In a cardiac catheterization operation, the utility model can replace the hemostatic operation of compressing the artery with fingers of doctors after the operation. The utility model has the advantages of simple and safe operation, easy fabrication and low cost, having the application to all hospitals.

Description

Arteria compressing hemostat

This utility model belongs to technical field of medical instruments.

Before the present utility model, for the hemostasis method of cardiac catheterization artery, generally adopt finger-press method in the prior art, sandbag method or rubber band method.Finger-press method and sandbag method be not only time-consuming, effort, and safety inadequately, and more patient's bleeding or subcutaneous oozing of blood are arranged, and especially for hypertensive patient, dangerous degree is just bigger.And for wartime wound, tremulous pulse from the breakdown wound etc., the hemostasis by ligation band that the rubber band method is adopted in the interruption artery blood flow, has also been blocked the backflow of venous blood, makes the fortune end tissue necrosis time shorten.

At above-mentioned present situation, the purpose of this utility model is to design a kind of easy tremulous pulse compression apparatus, but makes its purpose that reaches the option table shallow artery on convenient, practical basis, and safety, and is reliable, rapid, simple and direct.

Now this utility model design and technical solution are described below:

This utility model is formed (see figure 1) by haemostat pressing plate 1, compressing piston 2, lock pin handle 3, lock pin 4, lock pin active lever 5, rubber compressing medicated cap 6 etc., the two ends of haemostat pressing plate 1 have two slotted holes 7, so that penetrate fixing band 9, the centre has two protruding rectangular opening 8(of arc and sees Fig. 3), compressing piston 2 is two protruding cuboids of arc, have several ratchet (see figure 2)s on the bilateral cambered surface of the protruding cuboid of this pair arc, in order to block lock pin active lever 5, rubber compressing medicated cap 6 is equipped with in the bottom of compressing piston 2, in order to the compressing blood vessel, to reach the hemostasis purpose.Lock pin active lever 5 is L-shaped, its angle is fixed on the hemostasis pressing plate 1 with lock pin, fulcrum as active lever, the angle that the arm of force 10 on fulcrum both sides, the arm of force are 11 is 110 °＞α＞90 ° (see figure 4)s, the top of the arm of force 11 is connected to extension spring 12 extension springs, the other end is fixed on the haemostat pressing plate 1, in working order down, with finger compressing piston 2, lock pin active lever 5 is under the effect of extension spring 12 simultaneously, block the ratchet on the compressing piston 2, compressing piston 2 can be fixed by the position and the degree of depth of required compressing blood vessel.Under off working state, pinch the lock pin lever handle 3 of oppressing the piston bilateral with hands, make the arm of force 11 on the lock pin active lever produce displacements, the arm of force 10 breaks away from the ratchet on the compressing piston, compressing piston 2 can be return original position, unties fixing band 9 then, and hemostasis by compression work promptly stops.This haemostat can be made the various different sizes of different size according to practical situation, to adapt to order in various years, the requirement at various operations and various different arteries position.

Now that description of drawings is as follows:

Fig. 1: tremulous pulse compression apparatus forward is thrown view.

Fig. 2: tremulous pulse compression apparatus side sectional view.

Fig. 3: haemostat pressing plate

Fig. 4: lock pin active lever card and the state diagram of not blocking the compressing piston.

Wherein: 1, haemostat panel, 2, the compressing piston, 3, the lock pin handle, 4, lock pin, 5 lock pin active levers, 6, rubber compressing medicated cap, 7, slotted hole, 8, the protruding rectangular opening of two arc, 9, fixing band, 10, the arm of force, 11, the arm of force, 12, extension spring, 13, cover plate.

The utility model is compared with prior art, in cardiac catheterization, both can replace the operation of postoperative doctor finger pressure artery hemostasis, has again advantage simple to operate, safe and reliable; Have equally easy and simple to handle, the selective characteristics such as strong being used for the artery trauma hemostasis by compression. The manufacturing of this haemostat is simple, and is with low cost, can promote the use of in each hospital.

Claims (2)

1, a kind of tremulous pulse compression apparatus, it is characterized in that: by hemostasis pressing plate, compressing piston, extension spring, lock pin, lock pin handle, lock pin active lever, rubber compressing medicated cap constitute, the compressing piston is two protruding cuboids of arc, the prominent face of two arcs is provided with ratchet, the hemostasis panel is provided with two protruding rectangular openings of arc, and the lock pin active lever is L shaped, and angle is 110 °＞α＞90 ° between its two arm of force.

2, a kind ofly it is characterized in that according to the tremulous pulse compression apparatus described in the claim 1 that fixedly lock pin active lever institute is as its fulcrum with lock pin, one of them arm of force connects with extension spring.
