Description

Technical Field

[0001] The utility model relates to a medical device, in particular to a dialysis chair armrest with a hemodialysis blood seepage alarm. Background Art

[0002] Hemodialysis is one of the renal replacement therapies for patients with acute and chronic renal failure. It drains blood from the body to the outside of the body through a dialyzer composed of countless hollow fibers. The blood and an electrolyte solution (dialysate) containing electrolytes at similar concentrations to the body are exchanged inside and outside the hollow fibers through the principles of diffusion, ultrafiltration, adsorption and convection, thereby removing metabolic waste from the body and maintaining electrolyte and acid-base balance. At the same time, it removes excess water from the body and returns the purified blood. The entire process is called hemodialysis. Once the equipment used in hemodialysis has bleeding or bleeding, it needs to be treated immediately, otherwise it will have serious consequences. Therefore, medical staff need to detect bleeding in hemodialysis in a timely manner.

[0003] During hemodialysis, the patient usually sits on a dialysis chair and places his arms on the armrests, and the dialysis needle pierces the skin of the patient's arm.

[0004] Therefore, how to design a dialysis chair armrest that can provide a bleeding alarm during hemodialysis has become an urgent problem to be solved in the field of medical devices. Utility Model Content

[0005] The utility model aims to provide a dialysis chair armrest with a hemodialysis blood seepage alarm. When blood seepage occurs during hemodialysis, the alarm reminds the medical staff to discover and handle it in time, thus avoiding shock caused by excessive blood loss of the patient.

[0006] In order to achieve the above-mentioned invention object, the utility model adopts the following technical solutions:

[0007] A dialysis chair armrest with a blood seepage alarm includes an armrest board and a pressure pad. The patient's arm is placed on the armrest board, and the pressure pad is pressed against the dialysis puncture site. A first sensor is provided on the skin-contacting surface of the pressure pad, and the first sensor detects whether there is blood seepage at the dialysis puncture site. The armrest board is provided with an alarm, and the alarm is electrically connected to the first sensor.

[0008] Compared with the prior art, the dialysis chair armrest with hemodialysis blood seepage alarm using the above technical solution has the following beneficial effects:

[0009] 1. When the dialysis chair armrest with hemodialysis blood seepage alarm is used, the patient's arm is placed on the armrest. When bleeding occurs at the hemodialysis puncture site of the patient's arm, the blood is stained on the surface of the first sensor of the pressure pad contacting the skin, triggering the alarm to send out an alarm signal. Medical staff can discover and deal with it in time to avoid shock caused by excessive blood loss.

[0010] 2. There are two reasons for bleeding during hemodialysis. One reason is that the patient's arm movement causes the dialysis puncture needle to be detached from the skin. The other reason is that the dialysis tube joint is not tightened and accidentally loosens. Use a pressure pad to apply pressure to the dialysis puncture site on the arm to prevent the dialysis needle from being detached from the skin.

[0011] 3. In the preferred embodiment, the dialysis tube connector is clamped in the clamping groove of the tube clamp to prevent the dialysis tube connector from accidentally loosening; moreover, when bleeding occurs at the dialysis tube connector, the blood sticks to the surface of the second sensor on the inner wall of the clamping groove, triggering the alarm to send an alarm signal, so that medical staff can discover and deal with it in time to avoid shock caused by excessive blood loss in patients.

[0012] Preferably, an armrest pad is provided on the armrest board, and a triangular positioning groove is provided on the armrest pad, and the groove walls on both sides of the positioning groove are inclined, and the patient's arm is placed obliquely in the positioning groove. The positioning groove plays a positioning role for the patient's arm, preventing the patient's arm from accidentally turning over, and keeping the patient's arm in an oblique position.

[0013] Preferably, the angle between the two side walls of the positioning groove is 90°, and the angle between the two side walls of the positioning groove is rounded. The positioning groove of the armrest pad fits the patient's arm closely, increasing the contact area and making the patient's arm feel comfortable.

[0014] Preferably, a strap and a buckle are provided on both sides of the pressure pad, the movable end of the strap passes over the top of the positioning slot, and is fixed by Velcro after passing through the buckle, and the pressure pad is arranged on the surface of the strap close to the positioning slot, so that the patient's arm is clamped between the skin-contacting surface of the pressure pad and the side wall of the positioning slot. The medical staff adjusts the length of the strap extending from the buckle, thereby adjusting the pressure exerted by the pressure pad on the patient's arm according to needs, and it is suitable for the arms of patients of different body shapes.

[0015] Preferably, the pressure pad is detachably connected to the bandage, and the pressure pad is provided with a belt ring through which the bandage passes. The medical staff pulls the bandage out of the belt ring to remove the pressure pad from the bandage, and the pressure pad can be replaced and cleaned to keep the pressure pad clean and avoid cross infection.

[0016] Preferably, the armrest pad moves along the length direction of the armrest board. Medical staff can move the armrest pad to different positions on the armrest board according to needs, which is suitable for different dialysis puncture positions of the patient's arm.

[0017] Preferably, the utility model also includes two tube clamping members, each of which is provided with a clamping groove, and a second sensor is provided on the inner wall of the clamping groove, the second sensor is electrically connected to the alarm, and the two dialysis tube connectors are respectively clamped in the clamping grooves of the two tube clamping members, and the second sensors of the two tube clamping members respectively detect whether the two dialysis tube connectors are bleeding. When the dialysis tube connectors are bleeding, the blood is stained on the surface of the second sensor, triggering the alarm to send out an alarm signal.

[0018] Preferably, the tube clamp is provided with a trapezoidal base, the bottom surface of the base is flat, and the bottom surface of the base is made of elastic silicone material. The bottom surface of the base is close to the skin of the patient's arm, which plays a limiting role for the tube clamp. The bottom surface of the silicone material can increase friction and improve skin-friendly feeling, prevent displacement and twisting of the dialysis tube, and avoid accidental loosening of the dialysis needle and dialysis tube joint to cause bleeding.
