Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-5, the present invention provides an embodiment: jaw type tourniquet, including metal support 1, metal support 1 includes handle A101, handle B102, and handle A101, handle B102 form by the integrative concatenation of slope section 103, horizontal segment 104, and the slope section 103 of handle A101, handle B102 articulates each other and the tip of slope section 103 is integrative fixedly connected with jaw A105, jaw B106 respectively, and handle A101, the horizontal segment 104 of handle B102 then parallel arrangement from top to bottom.

Specifically, a groove 9 is formed in an inclined section 103 of the handle A101, the groove 9 is matched with the inclined section of the handle B102 in shape, the handle A101 and the handle B102 are overlapped in a crossed mode at the groove 9, and a through hole 10 penetrating through the handle A101 and the handle B102 is formed in the overlapped position. The support rod 16 is fixedly arranged on the connecting seat 11, the support rod 16 is inserted into the through hole 10 and is rotatably connected with the through hole 10, the connecting seat 11 is arranged on the metal bracket 1 through the support rod 16, and meanwhile, the handle A101 and the handle B102 are hinged. The nut 17 is connected to one end of the supporting rod 16 extending out of the through hole 10 through a thread, the inclined sections 103 of the handle A101 and the handle B102 are clamped and fixed in the middle by the nut 17 and the connecting seat 11, and the tightness of the hinged position of the handle A101 and the handle B102 can be adjusted by adjusting the position of the nut 17 on the supporting rod 16, so that the hinging effect is guaranteed.

Preferably, in order to prevent the handle a101 and the handle B102 from being opened and closed due to the abrasion of the support rod 16 after long-term use, and to facilitate disassembly, assembly, maintenance and maintenance, the sleeve 19 is coaxially sleeved on the portion of the support rod 16 located in the through hole 10, and the bearing 18 is coaxially sleeved outside the sleeve 19. The bearing 18 enables the handle A101 and the handle B102 to rotate smoothly relative to each other, mutual friction is reduced, the service life is prolonged, and the sleeve 19 can fix the bearing 18, so that the stability of the bearing 18 is ensured, and the supporting rod 16 can be protected, so that abrasion is prevented.

Preferably, the jaws a105 and B106 are arc-shaped and have opposite openings and are arranged vertically and symmetrically. The left ends of jaws a105 and B106 away from the hinged position are spaced apart such that jaws a105 and B106 form a jaw therebetween for gripping a patient's arm or arm. The big air bag 2 integrally and hermetically wraps the jaw A105 and the jaw B106. Preferably, in order to ensure that the disposable bag is used by one person and is clean and sanitary, the large air bag 2 is further wrapped with a disposable plastic bag 3, the disposable plastic bag 3 is convenient to replace, is extremely thin, and is extremely low in use cost.

The timer 4 is fixedly connected to the horizontal section 104 of the handle a 101. The timer 4 is a mature product available on the market, and therefore, the structure and the usage thereof are not described herein. During the use, can regularly with timer 4 according to the demand, the nurse is reminded promptly to the time, prevents effectively that the nurse from forgetting to disassemble the tourniquet.

The inner walls of the horizontal sections 104 of the handles A101 and B102 are respectively fixedly connected with an air bag seat 7, an air bag 8 is fixedly arranged between the two air bag seats 7, the air bag 8 is communicated with the large air bag 2 through an air pipe 14, and the middle part of the air pipe 14 is positioned in the horizontal section 104 of the handle B102. The airbag 8 is disposed between the handles a101 and B102, and can be inflated by pinching with the hand or by squeezing the handles a101 and B102. Horizontal segment 104 of handle B102 is close to left end lateral surface rotation of pincers A105 and is provided with fixture block 13, and is concrete, and the fixture block 13 front end is located outside horizontal segment 104, and the rear end stretches into horizontal segment 104 in and the tip fluting, trachea 14 middle part one end is located this inslot for trachea 14's middle part obtains supporting, is favorable to the gas circulation. Under normal conditions, the pipeline of the air pipe 14 is unblocked, when the air pipe is full of air and the air flow needs to be blocked, the clamping block 13 is manually rotated, the middle part of the air pipe 14 is folded in the rotation process, so that the air flow is blocked, and the air leakage of the large air bag 2 through the air pipe 14 is effectively prevented.

The inner walls of the horizontal sections 104 of the handle A101 and the handle B102 are fixed with spring guide rods 5, the two spring guide rods 5 are arranged in an up-down symmetrical mode but are not in contact with each other, the same spring 6 is coaxially sleeved outside the two spring guide rods 5, and two ends of the spring 6 are respectively fixed on the handle A101 and the handle B102. The spring 6 is provided to prevent the handle a101 and the handle B102 from being separated too much to be stored, and also to prevent the airbag 8 from being damaged by being pulled too much.

Preferably, the outer surfaces of the horizontal sections 104 of the handles a101 and B102 are provided with finger grooves 15 for the nurse to grasp. More preferably, the inner wall of the finger groove 15 is provided with a rubber pad 20, and the rubber pad 20 has elasticity, so that the medical staff can not only prevent slipping but also be more convenient to hold, and the gripping comfort level is improved.

The working principle of the forceps-type tourniquet of the utility model is as follows:

before use, a nurse firstly sleeves the disposable plastic bag 3 on the surface of the large air bag 2, then the arm or the arm of the patient is inserted into the jaw, then the nurse pinches the handle A101 and the handle B102 to enable the handle A101 and the handle B102 to be close to each other until the arm or the arm of the patient is clamped, then the air bag 8 is pinched by the hand to be inflated, meanwhile, the handle A101 and the handle B102 can be pinched again to squeeze the air bag 8 to be inflated, after the air is filled, the large air bag 2 is inflated, and the arm or the arm of the patient is clamped to a required state. For preventing that the nurse from forgetting to remove the tourniquet, can set up the definite time with timer 4 before beginning to aerify, then alright warning suggestion nurse in time solve the tourniquet of this application.

The clamp-on tourniquet of this application is simple structure, convenient operation, and blood vessel exposure time is fast, is showing and is improving nurse work efficiency, and the safety in utilization is high simultaneously, has effectively avoided the nurse to forget the unfavorable consequence that the tourniquet produced of relieving.
