A T TORNE Y INTRAVENOUS CATHETER APPARATUS WITH CATHETER TELESCOPEI) INSIDE PUNCTURING CANNULA My invention relates to an intravenous catheter apparatus for inserting a flexible venous catheter into a patients vein. These flexible venous catheters are often inserted into a patients vein so he can move his arm without a rigid cannula gouging into his vein.
There are basically two types of intravenous catheter apparatus. One has the flexible catheter on an outside surface of the puncturing cannula and the other has the flexible catheter fed down through the cannulas bore. I have a related application filed on even date entitled Intravenous Catheter Apparatus with Catheter Telescoped on Outside of Puncturing Cannula" Ser. No. 645,655 filed June 13, 1967 deals with the former type. The present application deals with the latter type.
In this application (catheter inside cannula) I have provided three embodiments of a unique hub construction for holding the cannula while making the venipuncture. In one embodiment, this hub has a pair of opposed jaws which grip tightly around the cannula. Once the venipuncture is made, the jaws separate and the entire hub can be pulled back over the catheter, leaving only the cannula on the catheter. The cannula slides to a rear of the catheter where it is encased in a protector that keeps the cannulas sharp puncturing end from damaging the catheter.
My invention can best be understood with reference to the drawings, in which:
FIG. 1 is a side elevational view of the intravenous catheter apparatus showing a first embodiment of my hub construction;
FIG. 2 is a cross-sectional view taken along line 2-2 of FIGURE 1;
FIG. 3 is an enlarged side elevational view of the first embodiment of my split hub;
FIG. 4 is a cross-sectional view taken along line 4-4 of FIGURE 1;
FIG. 5 is a top plan view of the venous catheter and cannula with the cannula encased in a first embodiment of my cannula protector;
FIG. 6 is a front elevational view of this first embodiment cannula protector showing it in open position;
FIG. 7 is a side elevational view of this first embodiment cannula protector;
FIG. 8 is a side elevational view of a second embodiment of the cannula protector showing it in open position;
FIG. 9 is a top plan view of a second embodiment of my split-apart hub;
FIG. 10 is a side elevational view of this second embodiment hub showing a removable cam locking member;
FIG. 11 is a front elevational view of this second embodiment hub;
FIG. 12 is a top plan view of a third embodiment of my splitapart hub;
FIG. 13 is a side elevational view of this third embodiment hub; and
FIG. 14 is a front elevational view of this third embodiment hub. Referring in detail to these drawings, the intravenous catheter apparatus includes a cannula 1 with a flexible venous catheter 2 slideable through its bore. A rearward end of this cannula is tightly held in a hub 5. A first embodiment of this hub (FIGS. 1-4) includes a sheath-receiving portion 6 with a rigid lower jaw 7 and a hinged upper jaw 8 attached to this sheath-receiving portion 6. Opposed grooves 10 and 11 in the jaws present surfaces which tightly grip against an outside surface of the cannula and are held in this relationship by a removable rigid band 9. One of the grooves 10 or I] has a shoulder 12 against which a rear end of the cannula abuts when pushing the cannula into a vein.
Extending rearwardly through the hub is venous catheter 2 which has a hollow adapter 3 at its rear end with a tapered internal surface for connecting to an administration set. When not so connected, a plug 4 closes off the adapter. These elements (rearward portion of catheter, adapter and plug) are all protected from contamination by a flexible sheath 23 which is removably connected to sheath-receiving portion 6 of the hub.
In the past there has been some problem with the puncturing cannula of such apparatus. The puncturing cannula has a sharp edge at its forward end through which the soft flexible catheter extends. If the catheter is flexed and the cannula moves along the catheter, the cannula's sharp point can gouge into the soft catheter, possibly severing its wall. I have overcome this disadvantage by providing a protector for cannula I.
A first embodiment of this protector 14 (shown in FIGS. 5-7) includes a pair of panels 15 and I6 with opposed grooves 18 and 19 for holding the cannula. These grooves are narrowed at their ends sufficiently to prevent the cannula from slipping out but still let the catheter pass through the protector. The panels 15 and 16 have their ends hinged together at 17. They are hinged on just one side of the grooves and have a transverse opening 22 leading into the grooves. Thus, the cannula protector 14 can be laterally slipped onto the catheter. Catch members 20 and 21 hold the panels together to encase the cannula and keep it from gouging into the catheter.
In a second embodiment of the protector (FIG. 8) the panels 24 and 25 are hinged along their sides by hinge 26. This second embodiment of the protector with grooves 27 and 28 can also laterally slip onto the cannula and be clamped shut to protect the cannula.
Both cannula protector embodiments are preferably made of polypropylene plastic with integral polypropylene hinges between panels 15 and I6 and panels 24 and 25.
Having described in detail the cannula protector, we turn now to the second and third embodiments of my hub. The first embodiment (FIGS. 1-4) has been described previously.
The second embodiment (FIGS. 9-11) of my hub has a base wall 30 with a pair of upstanding arms 31 and 32 on opposite sides of cannula l. A lid 33 pivotally connects to these upstanding arms through pivot shafts 34 and 35 which fit into pivot pockets in these arms. Numeral 36 denotes the pivot pocket in arm 31, and there is a like pivot pocket in arm 32.
This lid 33 swings longitudinally towards base wall 30 and a portion 37 tightly clamps the cannula 1 against base wall 30. If desired, lid 33 can grip against a hub 48 on one end of cannula 1. Holding the lid 33 and base wall 30 in this gripping relationship is a cam member 40 with pivot shafts 4! and 42 that removably fit into pivot pockets in a second set of upstanding arms 38 and 39. Numeral 43 denotes the pivot pocket in arm 38 and arm 39 has a like pivot pocket. To open this embodiment of my hub, the operator pulls up on a handle of cam member 40 to release cam pressure on lid 33. After removing cam member 40 he then swings open lid 33 and pulls pivot shafts 34 and 35 out of the pivot pockets in upstanding arms 31 and 32. This lets the base wall 30 and the upstanding arm portions of the hub slide out from under the cannula.
Another feature of this second embodiment of the hub is the way a flexible sheath 23 is held to the hub. On each side of cannula 1 are cavities 44 and 45 in base wall 30 which can extend completely through the base wall if desired. Cooperating with these cavities are lugs 46 and 47 on lid 33 which push the flexible sheath 23 into the cavities where it is retained. When the lid is removed to release catheter 2, it simultaneously releases flexible sheath 23.
The third and final embodiment of my hub (FIGS. I2-I4) has a base wall 50 also with upstanding arms 53 and 54. Here, however, the lid 55 is hingedly connected to one arm 53 and transversely swings across the cannula l to grip the cannula or a hub 48 at one end of the cannula l to base wall 50. An opening 56 in lid 55 receives a catch means 57 on upstanding arm 54 to lock the lid against the cannula. As in the second embodiment, lugs and 61 cooperate with cavities 58 and 59 to simultaneously grip the flexible sheath 23.
The three hub versions described above can be made of various materials. However, the first and third embodiments are preferably made of polypropylene plastic with an integral polypropylene hinge between the jaws of the first embodiment and between the lid and upstanding arm of the third embodiment.
Having explained the structure of the various embodiments of my invention, we now turn to a brief description of how it is used. First, the operator takes the intravenous catheter apparatus as shown in FIG. 1 and makes the venipuncture'. Next, he pulls off band 9 (or removes cam member 40 or releases catch 57) and opens up the hub to release pressure on the cannula. He then pulls the flexible sheath 23 and the hub back over the catheter. He can remove the flexible sheath 23 and hub while they are still connected to each other or he can pull flexible sheath 23 off of hub 5 and remove them separately. Enlarged catheter opening 13 in hub 5 passes over adapter 3 and plug 4. Next, he slides the cannula rearwardly along the catheter and locks it inside the cannula protector 14. Finally, all that remains is a flexible catheter in the patients vein. There is no rigid cannula that can cause injury to him.
In the foregoing specification, I have described my invention using certain specific embodiments. It is understood that persons skilled in the art can make modifications to these embodiments without departing from the spirit and scope of this invention.
