Embodiment approach

[0033] The most preferred implementation is as follows:

[0034] The shell 1 and the motor bracket 13 are fastened together by four screws. The motor bracket 13 is divided into a lower load-bearing part and an upper fixed part. The load-bearing part adopts a trapezoidal hollow design, and the interior is divided into two parts; The groove is designed to firmly embed the motor 21 in it to avoid accidental rotation of the motor 21 during work and affect the smooth operation of the machine as a whole; the fixed part is a longitudinal integrated cover plate fixed to the bottom of the motor 21 by four screws to avoid The motor 21 moves horizontally; there is a through hole for the wire in the middle, which is convenient for later debugging and wiring.

[0035]The slide rail base 27 is fixed through the pre-designed card slot inside the housing 1. The slide rail base 27 is designed in a "concave" shape, and the first bearing seat 23 and the second bearing seat 24 are embedded in the...

Abstract

The arm vein tourniquet comprises a shell, a vein pressing module and a driving module, symmetrical guide grooves are formed in the two side walls of the shell, the vein pressing module comprises a vein pressing unit and a movable workbench, connecting frames are arranged on the two sides of the movable workbench, a movable workbench body is installed in the shell, and the driving module is connected with the connecting frames. The connecting frame extends out of the guide grooves in the two sides, the driving module is installed in the shell and connected with the movable workbench, and the driving module drives the movable workbench to slide in the axial direction of the shell. The pulse pressing unit comprises a shell, a disinfectant storage chamber and an air pump are distributed in the shell, and cameras, outer side disinfection nozzles and inner side disinfection nozzles are arranged on the two sides of a middle groove of the shell. Compared with the prior art, the nursing bed is simple in structure and high in integrity, does not occupy a large space, and is easy for medical staff to carry, disassemble and use; the fitting degree with the human arm is good; the sanitary safety coefficient is high.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an arm vein tourniquet for assisting venipuncture. Background technique [0002] In medical practice, when intravenous infusion or blood collection, it is necessary to tighten the rubber tube to increase the partial filling of the vein, which is conducive to venipuncture. However, the traditional method has many problems, such as time-consuming, complicated operation, increased workload of medical staff, difficulty in disinfection, and potential risk of cross-infection. At the same time, in the field of intelligent medical care that is currently developing rapidly, especially in the process of machine blood drawing or intravenous injection for patients, relying solely on ultrasound, camera and other technical means, accuracy is still common in some special scenarios. , accuracy, and other issues, and it has high requirements on algorithms and external conditions. If the automatic ...
