Description

Technical Field

[0001] The utility model relates to the technical field of intelligent medical devices, in particular to an arm fixing device for machine blood collection. Background Technique

[0002] In the traditional clinical blood collection process, nurses' experience and skills are usually relied on to locate the patient's blood vessels, and a soft pad at the bottom of the arm is used to assist in fixing the patient's arm. Due to the flexibility of manual operation, the patient can adjust the arm position under the guidance of the nurse to facilitate finding the best puncture point. However, with the development of medical technology, machine blood collection has gradually become possible. Machine blood collection mainly relies on precise blood vessel recognition technology. Therefore, the stability of the patient's arm and the accurate positioning of the blood vessels in the cubital fossa have become particularly crucial. The blood vessels in the cubital fossa are closer to the skin surface, easy to identify, and cause less pain during puncture. However, if the patient moves the arm during blood collection, it may interfere with the blood vessel positioning and puncture process, which requires higher requirements for the fixation and positioning accuracy of the patient's arm.

The cavity formed between the support base 22 and the upper pressure plate 23 is used to support and fix the arm. A pressure sensor is also provided between the upper pressure plate 23 and the support frame 21. In this embodiment, the number of pressure sensors is two, which are respectively fixed at different positions between the upper pressure plate 23 and the support frame 21, and are used to measure the pressure on the patient's arm when the patient's arm is fixed, so as to avoid harm to the patient's arm.

[0029] The holding handle mechanism 3 includes a handle 31, a moving guide rail 32, a guide groove 33, and a fixed electromagnet 34. The moving guide rail 32 is fixed on the surface of the support part 12, the guide groove 33 is fixed on the handle 31 and moves along the moving guide rail 32, and a fixed electromagnet 34 is provided on the guide groove 33 to realize adsorption and fixation with the moving guide rail 32. When the arm support and fixation mechanism 2 places the patient's arm in a suitable position, the patient holds the handle 31. When reaching the suitable position, the arm determination button on the blood collection machine is activated, and the fixed electromagnet 34 starts the magnetic adsorption work to realize the fixation of the handle 31.

[0030] The drape feeding and recycling mechanism 4 includes a first drape feeding and recycling unit 41 and a second drape feeding and recycling unit 42. The first drape feeding and recycling unit 41 includes a first feeding reel 411, a second feeding reel 412, and a first recycling reel 413. The second drape feeding and recycling unit 42 includes a third feeding reel 421 and a second recycling reel 422. The first drape feeding and recycling unit 41 is used for feeding and recycling the drape for the arm support and fixation mechanism 2. Specifically, the first feeding reel 411 is fixed on one side of the support portion 12, and the first recycling reel 413 is fixed on the other side of the support portion 12. The drape located on the first feeding reel 411 passes through the upper surface of the support base 22 and is wound onto the first recycling reel 413. The second feeding reel 412 is fixed on the top side of the support frame 21, and the drape located on the second feeding reel 412 passes through the lower surface of the upper pressure plate 23 and is wound onto the first recycling reel 413. The second feeding reel 42 is used for feeding and recycling the drape for the holding handle mechanism 3.

The drape on the third feeding reel 421 passes through the surface of the handle 31 and is wound onto the second recycling reel 422.

[0031] For the arm fixation device for machine blood collection provided by the present utility model, the usage process is as follows. When the blood collection machine receives the patient information, the support base 22 of the arm support and fixation mechanism 2 is lowered to the lowest position by the base drive motor 24. At the same time, the reels of the first recycling reel 413 and the second recycling reel 422 rotate, and a pollution-free new drape covers the support base 22, the upper pressure plate 23, and the handle 31. The patient's arm is placed on the support base 22, and the handle 31 is held with the palm facing up. The handle 31 is moved back and forth so that the elbow of the patient's arm is placed in the center of the support base 22. The arm position fixation confirmation button on the blood collection machine is pressed. At this time, the fixed electromagnet 34 starts to work to fix the handle 31. At the same time, the support base 22 lifts the arm upward to the upper pressure plate 23. As the support base 22 continuously lifts the arm, when the pressure sensor between the upper pressure plate 23 and the support frame 21 reaches the preset threshold value, the movement of the support base 22 stops. At this time, the fixation and positioning of the entire arm are completed.
