Problems solved by technology

For medical staff, repeating the above actions continuously and frequently, the labor intensity is very high, they are prone to fatigue, and the overall time spent on drawing blood from a patient increases
In addition, medical staff manually bind the tourniquet, and there is also the problem of improper tightness, which may make the veins not obvious, which will easily cause puncture failure and increase the pain of patients

Embodiment 1

[0043] Basic as attached figure 1 , attached figure 2 And attached image 3 As shown, the device for automatically binding a disposable tourniquet includes a workbench 1 with a through hole 11, and the upper part of the workbench 1 is made of a transparent material, such as transparent glass. The top of workbench 1 is transparent and can observe the working situation in the through hole 11.

[0044] There is a chute located on the outer periphery of the through hole 11 on the workbench 1, and a driven gear 3 is arranged on the workbench 1. The driven gear 3 is concentric with the through hole 11. The driven gear 3 is welded with a chute extending into the chute. A plurality of slide blocks, the slide blocks are evenly distributed along the circumference of the driven gear 3, and the slide blocks are slidably connected with the chute. The driven gear 3 meshes with the driving gear 5, and the gear ratio between the driving gear 5 and the driven gear 3 is 1:5-1:10. In this em...

Embodiment 2

[0052] The difference between embodiment two and embodiment one is that, as attached Figure 7 As shown, the output shaft of the stepper motor 4 is fixed with a cam 51 coaxial with the driving gear 5, and an air box 13 is arranged below the cam 51, and the air box 13 is fixed on the workbench 1 by fastening bolts. Vertical sliding is connected with pressure plate 131 in the air box 13, and the bottom of pressure plate 131 is welded with the stage clip (not shown) that bears against with air box 13, and the top of pressure plate 131 is welded with the pressure plate that runs through air box 13 top walls. Push rod 134, push rod 134 and cam 51 offset.

[0053] The left side wall of the air box 13 is fixed with an intake check valve 132 by bolts, and the intake check valve 132 communicates with the air box 13. When the pressure in the air box 13 decreases, the gas enters the air through the intake check valve 132. In the box 13, the right side wall of the gas box 13 is fixed wit...

Abstract

The invention relates to the technical field of medical devices, and discloses an automatic-binding disposable tourniquet device which comprises a working table. A through hole is formed in the working table; a placement platform is fixed into the through hole; a driven gear concentric to the through hole is arranged on the working table and is rotatably connected with the working table; the driven gear meshes with a driving gear; the driving gear is driven by a drive piece; a rotating frame is concentrically fixed onto the driven gear; a recovery frame is fixed onto the rotating frame; a conveying frame far away from the recovery frame is fixed onto the working table; a recovery roller is rotatably connected onto the recovery frame, and is connected with a power piece fixed onto the recovery frame; a conveying roller is rotatably connected onto the conveying frame; a tourniquet is wound on the conveying roller; and one end of the tourniquet penetrates through the rotating frame and isfixed onto the recovery roller. The automatic-binding disposable tourniquet device provided by the invention is simple in structure, and facilitates replacing, collection and binding of the tourniquet.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a device for automatically binding a disposable tourniquet. Background technique [0002] The tourniquet is a medical device used by clinical medical staff to puncture blood vessels. It is frequently used in blood drawing, blood transfusion, and infusion. When the tourniquet is used, it is usually tied to the patient's arm to highlight the blood vessels on the patient's arm. Blood draw or infusion is performed after the patient's blood vessel is punctured. [0003] Hose-type tourniquets have been used clinically, and hose-type tourniquets will be used alternately and repeatedly. This will lead to common phenomena such as non-sterilization or incomplete disinfection, and excessively long disinfection intervals, resulting in common problems such as serious contamination of tourniquets. Therefore, disposable tourniquets are widely promoted on the market at present. Disp...
