Abstract

Disclosed is a hemostasis clip for a dorsal hand venipuncture spot. The hemostasis clip comprises an upper clip body, a lower clip body and a spindle. The upper clip body and the lower clip body are respectively composed of a hand shank, a locking arm and a contact press block. The locking arm is arch-shaped. The contact press block is fixedly connected with the front portion of the locking arm. The hand shank is fixedly connected with the back portion of the locking arm. A shaft lug is arranged on a joint between the hand shank and the locking arm. The shaft lugs of the upper clip body and the lower clip body are connected by the spindle. A torsional spring is sleeved on the spindle. The locking arm is composed of a pair of arc-shaped rods. Anti-skidding lines are arranged on the surface of the contact press block. The hemostasis clip for the dorsal hand venipuncture spot has the advantages of being simple in structure, convenient to use, firm in fixing, accurate in pressing the spot, good in hemostatic effect, wide in application range, oppressing the dorsal hand venous transfusion puncture spot effectively, avoiding and reducing bleeding, saving physical strength of a patient and applicable to the patients after intravenous anesthesia, the patients advanced in age and poor in health with weak arms, children and the patients who can not press the puncture spots for stopping bleeding by themselves because of some other reasons.

Description

Hand back vein point of puncture hemostatic clamp

Technical field

This utility model relates to medical supplies, and the hemostatic clamp that particularly uses on the hospital clinical specifically, is hand back vein point of puncture hemostatic clamp.

Background technology

Along with the extensive use of various no pain inspections at hospital clinical, intravenous anesthesia the patient increase gradually.Take gastroscope as example, during traditional gastroscopy, owing to will check that pipeline stretches into the stomach from the oral cavity through esophagus, the complexion changed that people hear, that a lot of patients have is nauseating, the tolerance response not such as vomiting.

The comfortable safety of painless endoscopy is easy to accept, and is that various scopes (gastroscope, intestinal mirror, 12 finger mirrors etc.) check and the trend for the treatment of.Painless scope anesthesia is by implementing to hand back vein path injecting anesthetic medicine.Before the inspection, the patient sets position, by the fugitive tranquilizer of full-time anaesthetist's intravenous injection, the patient enters sleep state after 30 seconds, then begins endoscopy, namely stop administration after finishing endoscopy, the patient is at once fully clear-headed, returns to the state before checking, realizes fully clear-headed rear nurse until the patient and extracts intravenous infusion syringe, then, the patient press...withes one's finger and presses point of puncture to stop blooding.

Yet some patient is because the body constitution aspect waits reason slowly such as the Liver and kidney metabolism, and the arm Myodynamia recovery is slow, and orientation force is poor, can not effectively oppress point of puncture, causes point of puncture hemorrhage, the adverse consequencess such as subcutaneous extvavasated blood.Some patient is owing to having cardiovascular and cerebrovascular disease and the long-term taking anticoagulation, and coagulation function is poor, and often or compressing time inadequate because of the dynamics of pressing falls short of, and it is hemorrhage that point of puncture occurs.Therefore, need to stop blooding by the hemostasis instrument, the hemostasis instrument that uses in the Hospitals at Present mainly is mosquito forceps, in operation, to use, its shape, structure are similar to operating scissors, are not suitable for the back of the hand point of puncture, so be badly in need of a kind of hand back vein point of puncture hemostasis of research and development specific purpose tool.

The utility model content

For addressing the above problem, the purpose of this utility model provides a kind of hand back vein point of puncture hemostatic clamp, and simple to operate, easy to use, fixed, pressure point is accurate, and haemostatic effect is good, and is applied widely.

For achieving the above object, this utility model is by the following technical solutions:

A kind of hand back vein point of puncture hemostatic clamp, comprise upper and lower clamp and rotating shaft, it is characterized in that: described upper and lower clamp all is by handle, jig arm, presses piece and consist of, jig arm is arc, press piece and be fixed in the front portion of jig arm, handle is fixed in the rear portion of jig arm, and the joining place of handle and jig arm is provided with the axle ear, the axle ear of upper and lower clamp connects by described rotating shaft, and cover has torsion spring in the rotating shaft.

Described jig arm is made of a pair of bow.

The described surface that presses piece is provided with anti-slip veins.

Be provided with intervalometer on the jig arm of described upper clamp.

The described piece that presses is made by elastomeric material.

Because adopt technique scheme, this utility model has following positive beneficial effect:

This product can effectively be oppressed the hand vein transfusion point of puncture, prevents and reduces hemorrhagely, saves patient's muscle power, is applicable to the patient that patient, the old unable patient of arm, child and other reasons after the intravenous anesthesia can not be pressed the point of puncture hemostasis voluntarily.

Innovation of the present utility model is:

1, adopt the structure of handle, rotating shaft, jig arm, utilize lever principle to open, close up jig arm, the hemostasis point is exerted pressure, swift to operate, easy to use, pressure point is accurate, and dynamics is suitable.

2, the front end of jig arm is provided with and presses piece, presses piece and is made by elastomeric material, and is when being clamped in hand, more comfortable.The material that presses piece can be selected natural rubber or silica gel, and this class material and skin have affinity, are difficult for causing skin allergy, and the surface that presses piece is provided with anti-slip veins, when contacting with hand skin, and the dislocation of can not skidding, fixed, guarantee that pressure point is accurate.

3, handle, rotating shaft, jig arm can be made by medical plastic, and torsion spring is made by metal material, and this product structure is simple, and is cheap, can disposablely use, also can be through Reusability after the sterilization.

4, this product is divided into large size, medium size, trumpet, and its main distinction is that jig arm length is different with radian, thereby can select different model according to the hand size.

5, this product is divided into two, a without electronic timer, another money is with electronic timer, by the button on the electronic timer timing can be set, for general patient timing can be set is 10 minutes, for special patient, the poor patient of long-term taking anticoagulation coagulation function for example, timing can according to circumstances prolong.
