Abstract

The utility model relates to a hemostatic clip which comprises a first arc-shaped clamping arm (1) and a second arc-shaped clamping arm (2). The tail end of the first arc-shaped clamping arm (1) and the tail end of the second arc-shaped clamping arm (2) are connected together to form a sealed end, the other end of the first clamping arc-shaped clamping arm (1) and the other end of the second arc-shaped clamping arm (2) are provided with a first arc-shaped clamping arm twisting end (3) and a second arc-shaped clamping arm twisting end (4) respectively, the hemostatic clip can be opened or closed by twisting and movement between the first arc-shaped clamping arm twisting end (3) and the second arc-shaped clamping arm twisting end (4), and the closed hemostatic clip is wholly round or oval. The designed hemostatic clip is quite solid, the phenomenon that the hemostatic clip falls off or shifts due to behaviors of experimental animals is avoided, and the hemostatic clip is good in hemostasis effect, time-saving and labor-saving.

Description

Hemostatic clamp

Technical field

This utility model relates to medical instruments field, is specifically related to a kind of intravenous injection hemostatic clamp.

Background technology

At present, along with development biological and pharmaceutical technology, zoopery has become a kind of infrastest method of biology and medical science, medicine in clinical practice before human body, usually all need be by means of some laboratory animals, as mice, rat, rabbit, dog etc., pharmacodynamics, pharmacology and the toxicology etc. of medicine are studied.

In zoopery, the experimenter because laboratory animal has automatic control preferably unlike the people, can not reach people's cooperate degree after carrying out intravenous administration to laboratory animal, therefore need the experimenter to press cotton balls with hemostasis by compression with hands.If but bleeding stopping period needs more than 1 minute or during the longer time, can influence follow-up speed of experiment in the experiment.And the experimenter to press strength inhomogeneous, also may increase the misery of laboratory animal.Traditional hemostasis method wastes time and energy.

Notification number is in the utility model patent of CN201668446U, discloses a kind of venous transfusion hemostatic clamp, the rear end hinge of its upper frame and underframe, and front end is fixed with Magnet, and upper and lower framework is built-in with sebific duct.Notification number is in the utility model patent of CN201617892U, discloses a kind of intravenous injection hemostatic clamp, and it comprises operating grip and arc hemostatic clamp up and down.Notification number is in the utility model patent of CN2538284Y, discloses a kind of hemostatic clamp that is made of two clamping plate.The main application of these used for intravenous injection hemostatic clamps all is, before intravenous administration, hemostatic clamp is fixed in patient's wrist place, makes patient's blood vessel reach filling degree, is beneficial to the medical worker and accurately intravenous infusion syringe penetrated in the patient vessel.

But, in the prior art, also do not have to be used for pressing the intravenous injection hemostatic clamp of hemostasis behind the intravenous administration.Especially there is not the intravenous injection hemostatic clamp at laboratory animal.

The utility model content

At above shortcomings in the prior art, one of technical problem to be solved in the utility model provides a kind of intravenous injection hemostatic clamp.

This utility model purpose is achieved by the following technical solution:

A kind of hemostatic clamp comprises that the end of the first arc jig arm 1 and the second arc jig arm, 2, the first arc jig arm 1 and the second arc jig arm 2 links together, and forms blind end; The other end has the first arc jig arm twist end 3 and the second arc jig arm twist end 4 respectively, movement can be opened or closed hemostatic clamp by reversing between the first arc jig arm twist end 3 and the second arc jig arm twist end 4, and closed hemostatic clamp is whole rounded or oval.

Preferably,

There is pad 5 inboard of the first arc jig arm 1.

Described pad 5 has elasticity, is beneficial to the compressing to the bleeding part, accelerates anthemorrhagic speed.

Described pad 5 can be made for the rubber-like material.As rubber, cork, nylon and plastics.

Described pad 5 is by elastomeric element, as spring etc., is fixed in the hemostatic clamp inboard.

There is claw-like support component 6 the second arc jig arm, 2 inboards.

The preferred of claw-like support component 6 is plastic, to prevent the damage to animal.

Be placed with cotton wool in the claw-like support component 6, cotton wool can be changed at any time, and safety and sanitation prevent from polluting.

The end of the described first arc jig arm 1 and the second arc jig arm 2 preferably is connected by articulated manner.

This utility model compared with prior art has following advantage:

1, the intravenous injection hemostatic clamp of this utility model design is easy to use, laborsaving, and experimental implementation person can a hand control laboratory animal, and another hands one hand can be fixed in hemostatic clamp on the vein blood vessel of laboratory animal;

2, the hemostatic clamp of this utility model design can be changed cotton wool, prevents the cross infection of animal;

3, the hemostatic clamp of this utility model design is very firm, can hemostatic clamp be come off or be shifted, and haemostatic effect is good, saving experimenter's time.

Description of reference numerals: 1, the first arc jig arm; 2, the second arc jig arm; 3, the first jig arm twist end; 4, the second jig arm twist end; 5, pad; 6, claw-like support component.

The specific embodiment

Be further described below in conjunction with this utility model of embodiment.Definition contact laboratory animal one side is inboard in this utility model, and rightabout is the outside.

Embodiment

As illustrated in fig. 1 and 2, be a kind of hemostatic clamp, comprise that the end of the first arc jig arm 1 and the second arc jig arm, 2, the first arc jig arm 1 and the second arc jig arm 2 links together by articulated manner, form blind end; The other end has the first arc jig arm twist end 3 and the second arc jig arm twist end 4 respectively, movement can be opened or closed hemostatic clamp by reversing between the first arc jig arm twist end 3 and the second arc jig arm twist end 4, and closed hemostatic clamp is whole rounded or oval.

The inboard of the first arc jig arm 1 has and has the pad 5 that rubber is made, and pad 5 is fixed on the hemostatic clamp by spring; The claw-like support component 6 that the second arc jig arm, 2 inboards have plastics to make is placed with cotton wool in the claw-like support component 6.

After giving the laboratory animal intravenous administration, the first arc jig arm twist end 3 and the second arc jig arm twist end 4 are reversed closure, make on the firm limbs that are fixed on laboratory animal of hemostatic clamp, the cotton wool in the claw-like support component 6 is by being pressed in hemostasis place.

Haemostatic effect is good, and the firm difficult drop-off of hemostatic clamp is time saving and energy saving.

This utility model can be applicable to laboratory animals such as new zealand rabbit, rat, Cavia porcellus, dog and monkey.
