Abstract

A disposable device for clamping and cutting an umbilical cord or the like, comprising at least one clamp (1) slidably mounted in a holder (5). The holder further includes a knife (8). The cord is cut when the holder is moved along the clamp.

Description

A DEVICE FOR CLAMPING AND CUTTING E.G. AN UMBILICAL CORD.
The present invention relates to a device for squeezing and cutting e.g. an umbilical cord, and the device has at least one clamp with two legs interconnected by a hinge at one end of the clamp, and a holder by means of which the clamp can be closed. The holder has a knife cutting the umbilical cord after it has been squeezed by the clamp.
US-A- 4.856.517 relates to such a device where the holder consists of a lower part and an upper part interconnected by a hinge. The holder has two grooves into which two open clamps can be inserted. When the holder closes on an umbilical cord, the clamps are also closed. The holder and the clamps are locked in the end position. After the umbilical cord has thus been squeezed in two places, it is cut by a slide and knife being shifted on the holder between the two clamps. The locking mechanism of the holder is then released, and the two squeezed parts of the umbilical cord can be released from the holder. Because of the two-piece holder and the separate slide this prior art device is very complicated to make. And when the holder is opened after an umbilical cord has been cut, the knife is exposed which has to be considered very unfortunate from a safety point of view. The objective of the invention is to show a device of the said kind, but without the above-mentioned disadvantages. The device must, therefore, be simple to make (fewer parts and simpler shapes), and the knife must be placed so that it is always inaccessible. According to the Danish Working Environment Service, inaccessibility means that no access to the knife has an opening larger than approx. 6 mm. According to the invention this is achieved by the holder being provided with a through-going bore of a design allowing the hinged end of the clamp to be inserted in the bore and of a size allowing the holder to be moved along the legs of the clamp so that the clamp is closed and the knife of the holder is stationary and placed in such a way that the umbilical cord is cut when the clamp is closed and the holder is shifted further along the legs of the clamp.
To cut an umbilical cord, two clamps are normally used, and according to the invention it is, therefore, expedient that the holder should have a second identical bore, in parallel with the first-mentioned bore, for a second identical clamp and that the knife should be placed between the two bores.
In the said device, the knife is stationary inside the holder so that it will not be accessible even after cutting an umbilical cord. And the holder is constituted e.g. by a die cast part without a separate slide. The entire device thus consists of a holder and one or two clamps.
According to the invention it is expedient that the second clamp should have a catch at the free end of the legs for locking the clamp in the closed position, and that the second bore should open outwards and be equipped with blocking devices which interact with corresponding devices on the second clamp in order that the second clamp can be withdrawn through the opening when the holder is shifted past the position in which the clamp is locked and the umbilical cord is cut. When the umbilical cord has been cut, the second locked clamp can then be separated easily from the holder which is still locking the first clamp.
In what follows, the invention is described further in connection with the drawings where
Fig. 1 is a perspective of the disposable safety squeezing device in the open position, with two clamps of which the control clamp faces downward, Fig. 2 a side view of the disposable squeezing device in the open position and with the control clamp mounted, Fig. 3 a side view of the slide seen from one side, Fig. 4 a side view of the control clamp in the open position, Fig. 5 a side view of the second clamp in the open position,
Fig. 6 a side view of the slide seen from the other side, and
Fig. 7 a perspective of the disposable safety squeezing device in the closed position, with one clamp released after the umbilical cord has been cut.
Fig. 1 shows a disposable double squeezing device with a control clamp 1 and a second clamp 12.
The control clamp 1 and the second clamp 12 are pushed into through-going bores or grooves 13 and 13a in the slide 5. The slide 5 has two control tabs 6 and a partition 7 between the two grooves 13 and 13a. An inclined knife 8 is mounted in the partition 7.
Clamps 1 and 12 are secured in one direction in grooves 13 and 13a of the slide by their initial tension. In the opposite direction, at right angles to the first-mentioned direction, the control clamp 1 is secured by the outer wall 14 which closes the groove 13a, and some projections 9 which close the groove 13 for the second clamp 12.
The control clamp 1 has a contact part 3 (Fig. 4) which, when it is desired to use the second clamp 12, secures the latter in the same fixed position as the control clamp 1.
The second clamp 12 has recesses 11 which after shifting of the slide 5 to the closed position (Fig. 7) are placed opposite to the projec¬ tions 9 on the slide. In this position it is pos- sible to release the second clamp 12 from the slide 5. in its closed position the second clamp 12 is locked to the object by the catch 15.
Both clamps have recesses 4 in their longitudinal direction which secure that deformations caused by squeezing will take place in these recesses. The object which may be an umbilical cord is inserted in the opening between clamps 1 and 12 (Fig. 1). The control clamp 1 has a control part 2 which is used as a counterpressure part when the slide 5 is shifted with two fingers on the control tabs 6.
The object is squeezed during the first stage of shifting. Further shifting brings the inclined knife 8 of the slide into contact with the object which is then cut (Fig. 7). After cutting, the control clamp 1 continues to squeeze one part of the object and can be released from the object again by shifting the slide 5 in the opposite direction.
When released from the slide 5, the second clamp 12 remains locked in the closed position by the catch 15 and is released by cutting the spring bow 16 of the clamp.
