blood collection aids

technical field

The utility model relates to a blood collection auxiliary device.

Background technique

Human blood and blood components are indispensable in the diagnosis and treatment of modern medicine. Therefore, in the daily work of the hospital, it is often necessary to collect blood for testing to provide a basis for the doctor's diagnosis. In blood collection work, blood collection pads and cuffs need to be used. The current working method is that blood collection pads are superimposed one by one and placed in one position. A new blood collection pad is placed, and the tourniquet is also placed in a container one by one, and then taken out when in use, and recycled and sterilized after use. This mode of operation has loaded down with trivial details steps, and the nurse's blood collection efficiency is low.

Chinese patent 201420376298.1 discloses a transmission-type blood collection mesh pad. Through the use of the transmission wheel transmission device, each time the subject’s blood collection is completed, the transmission device will remove the used mesh pad and remove a new mesh pad to avoid the previous blood collection. The mesh pad dripping blood caused cross-contamination to the latter subject, which effectively ensured the hygienic safety of the venous blood collection process. The mesh pad structure of this patent improves work efficiency to a certain extent, but it does not solve the problem of inconvenient access of the current cuff.

Contents of the invention

The technical problem to be solved by the utility model is: to provide a blood collection auxiliary device which can automatically move and replace the blood collection pad and the cuff is easy to take, which solves the above-mentioned problems in the prior art.

The technical solution to solve the above technical problems is: a blood collection auxiliary device, including a support seat for supporting the human arm, a blood collection pad placement cylinder, a blood collection pad reel, a blood collection pad drive motor for driving the blood collection pad reel, The detection device for detecting the human arm and the controller for receiving the signal of the detection device and controlling the driving motor of the blood collection pad. cuff assembly, cuff storage box and cuff drive motor, the cuff storage box includes a box cover, a box body and a cuff installation shaft that is movably installed in the box body, the cuff body is opened There is a cuff outlet, the box body is installed on the support base, the cuff installation shaft is connected to the cuff driving motor, and the cuff driving motor is electrically connected to the controller. The cuff assembly is installed on the cuff mounting shaft and extends to the outside through the cuff outlet.

The cuff assembly is composed of a plurality of cuffs connected, a break line is provided between two adjacent cuffs for easy tearing, and a connecting piece that is bonded to each other is provided at the head and tail of each cuff , the cuff is a thin rectangular elastic stretchable band.

The thickness of the cuff is 0.1-0.3cm.

The connecting parts are Velcro.

The supporting base is also provided with pressing rods I and II for flattening the blood collection pad.

The utility model adds a cuff storage box on the basis of the existing automatic blood collection pillow, and the cuff adopts a thin rectangular elastic stretchable belt, which is convenient to be rolled into a circle and placed in the cuff storage box. During the blood collection process, while the blood collection pad is automatically moved and replaced, the cuff can be automatically sent out from the cuff storage box for nurses to use. This working method has a high degree of automation, which improves the nurse's blood collection efficiency, and the nurse no longer needs to take the cuff from another container, which solves the problem of inconvenient access to the cuff. In addition, the cuff and the blood collection pad are fused together, which not only saves the space occupied by the items, but also facilitates storage.

Below, the technical features of the blood collection auxiliary device of the present utility model will be further described in conjunction with the drawings and embodiments.

detailed description

Embodiment 1: A blood collection auxiliary device, as shown in Figures 1-6, includes a blood collection pillow, and the blood collection pillow includes a blood collection pad, a support seat 1 for supporting a human arm, a blood collection pad placement cylinder 2, and a blood collection pad reel 4 , the blood collection pad driving motor 11 for driving the blood collection pad rewinding shaft, the detection device 6 for detecting the human arm and the controller 10 for receiving the detection device signal and controlling the blood collection pad drive motor, the blood collection pad placement cylinder and the blood collection pad collection The reels are respectively installed on the support base and located on both sides of the support base. The blood collection pad placement cylinder is a cylinder with a blood collection pad outlet, and it is installed on the support base 1 through a detachable structure to facilitate the installation of the blood collection pad. The above-mentioned supporting seat is also provided with pressure rod I3 and pressure rod II5 for flattening the blood collection pad. The blood collection pad 8 is installed in the blood collection pad placement cylinder 2, passes through the upper end surface of the support seat 1 and is flattened by the pressure rod I3 and the pressure rod II5, and then wound up on the blood collection pad winding shaft 4.

In this embodiment, a cuff assembly 9, a cuff storage box 7 and a cuff drive motor 12 are also included. The cuff storage box 7 includes a box cover 71, a box body 72 and a cuff that is movably installed in the box body. The cuff mounting shaft 73, the cuff outlet 74 is arranged on the box body, the box body is installed on the support base, the cuff mounting shaft 73 is connected with the cuff driving motor 12, and the cuff driving motor It is electrically connected with the controller 10 , the cuff assembly 9 is circular, and the cuff assembly is installed on the cuff installation shaft and extends to the outside through the cuff outlet 74 .
