The present invention is not influenced by an operator and external factors.

Description

Telescopic device for suspension injection

Technical field

The present invention relates to a kind of medical infusion apparatus, particularly a kind of medical treatment, health department of being used for, the operator of being convenient to differing heights is convenient, the telescopic device for suspension injection of safe handling.

Background technology

Raising along with living standards of the people, the continuous improvement of medical condition, original drip stand of moving formula or being fixed on bedside, hinder patient's activity and medical worker's work again because of its occupation of land side eventually, and locking, localized pressure are relevant with the operator, use inconvenient, dangerous and are eliminated gradually.

The patent No. 96219931.1 " telescopic scalable drip stand ", though its location and locking are not subjected to the influence of operator's pressure, during use behind the only with hand Push switch, governor motion by its control is located automatically, is locked, use safelyr, reliable, but its structure is complicated, and part is many, difficult making, the production cost height.

Summary of the invention

Technical problem to be solved by this invention is: a kind of telescopic device for suspension injection is provided, and its simple in structure, easy making, production cost are low, are convenient to convenient, the safe operation of user of arbitrary height, and highly sensitive, telescopic adjustment speed is fast.

The present invention addresses the above problem the technical scheme that is adopted: telescopic device for suspension injection, comprise the hook rack that is externally connected with the band hook, in be connected with the interior pipe of control stick, be connected with the outer tube of suspension hook ring and by the governor motion of button control, interior pipe and outer tube are assembled into one, described governor motion is by described control stick, described button, the location keyframe of band spring and positioning key, button spring and be installed in have jack between pipe and outer tube positioning strip cooperate constitute, control stick connects described button, described location keyframe and described button spring, pinning button moves up control stick, the big end of control stick is put in the positioning key through hole, the compressing positioning key moves to the spring direction, thereby positioning key is withdrawn in the keyframe of location and break away from positioning strip on the contacting of jack, on, pipe release button to the desired location in moving down, effect lower control arm small end at button spring and gravity enters the positioning key through hole, positioning key is ejected under the effect of spring, tip in the jack on the positioning strip, thereby pipe and outer tube in automatically locking, the lower end of outer tube is fixed with low head, the upper end of outer tube and positioning strip, the suspension hook ring is fixed into one.

Compared with prior art, the invention has the advantages that: this apparatus structure is simple, inner and outer pipe, control stick, and the positioning strip of band jack is made into by pipe, square tube, round bar, iron plate, so easy processing and fabricating, cost is low.Because of the governor motion in this device is to cooperate with jack on the positioning strip by the positioning key on the control stick to finish, be not subjected to the influence of operator's pressure, have nothing to do with extraneous factor, so safe in utilization, reliable.Button is mounted in the lower end of control stick, is convenient to the user operation, especially can make things convenient for short people's operation, use.This device is simple to operate in addition, only with hand is pinned button, positioning key indentation at once disengaging contacts with positioning strip, interior pipe can upper and lowerly move on the desired position with regard to without hindrance, release button then, positioning key can stretch out again, reset to be buckled in the jack on the positioning strip and pin automatically, and telescopic adjustment speed is fast, highly sensitive.

The specific embodiment

Below in conjunction with accompanying drawing embodiments of the invention are described in further detail.

Outer tube 9 is made by rectangular tube, and at the tight embedding in upper and lower port place, rivet clasp upper cover 2, low head 10 is arranged, and upper cover 2, low head 10 are for the middle square pipe box that manhole is arranged, and be also porose on the two corresponding sidewalls.

Positioning strip 15 is the lengthy motion picture bar shaped, and a rectangle jack 17 and a through hole uniform, that size is identical are arranged on it.

Positioning key 18 is the middle rectangular block that through hole is arranged, and there is flange the centre at left and right edge, and a side of a flange is the inclined-plane.

Location keyframe 3 is the middle stairstepping that through hole is arranged, and big end is for square, and small end is circular, on one side of big end the hole that cooperates with positioning key 18 is arranged, the inside is placed with spring 19 and positioning key 18, and the waist hole that communicates is arranged on small end two corresponding side walls, is used to control the collapsing length of control stick.

Use pin 4 peg buttons 14 on one termination of control stick 8, the termination is stairstepping and conical transition in addition, near it convex tendon 7 places are with pad 6, button spring 5, and pass the waist hole of locating on the keyframe 3 and the through hole on the control stick 8 with pin 4, fixedly have the location keyframe 3 of spring 19, positioning key 18.

In three hook three open slots of 13 rivet clasps on hook rack 12, be fixed into holistic bottle stand, link up with not the time spent and can upwards draw in, bottle stand also can be made of two hooks or four hooks as required.

The control stick 8 that assembles is inserted oneself to be equipped with in the interior pipe 11 of bottle stand, deviate from for stopping the bottle stand landing, there is flange other termination of interior pipe, low head 10 covers on inner pipe, location keyframe 3 rivet clasps on the control stick 8 are fixed into one on the top of interior pipe 11, the outer tube 9 that will have upper cover 2 again is enclosed within outside the interior pipe 11, and insert positioning strip 15 in the crack betwixt, make positioning key 18 facing to positioning strip 15, at last suspension hook ring 1 is inserted in the upper cover 2, with screw with outer tube 9, positioning strip 15 and suspension hook ring 1, upper cover 2 is fixed into one, again low head 10 rivet clasps in the outer tube lower end, retractor device is assembled into.

Be fixed on this device on the ceiling or be placed in the slide rail that is fixed on the ceiling by suspension hook ring 1 and use by the pulley dolly.

Use for convenient:, can carry out long and short adjusting this retractor device according to the demand of operator's sub-height.During use, only with hand is pinned button 14 on pointing to, control stick 8 moves up, step-like small end 16 on it is reached outside the hole on the positioning key 18, and big end puts in the hole, and compressing positioning key 18 moves to spring 19 directions, and be withdrawn in the keyframe 3 of location, break away from positioning strip 15 on the contacting of jack 17, manage 11 unobstructed can going up in making, move down and regulate, up to the desired position, release button 14 again, under the effect of button spring 5 and gravity, control stick 8 returns to original position, and control stick small end 16 reenters the through hole on the positioning key 18, cannot keep under control spring 19, positioning key 18 is ejected again under the effect of spring 19, tips in the jack 17 on the positioning strip, thereby pins interior pipe 11 more automatically after reaching telescopic adjustment, the purpose of outer tube 9.

Time spent not after if liquid medicine has hung, can directly up shift control stick 8 onto satisfied height after, control stick 8 is pinning jack 17 automatically.
