Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a compression hemostasis device. Background Art

[0002] Blood tests are used to understand various indicators of the patient's physical condition, which helps medical staff understand the patient's condition and develop a treatment plan. After blood is drawn, pressure is required to stop bleeding for a period of time, 3-5 minutes for venous blood and 5-10 minutes for arterial blood. During this period, the patient or medical staff needs to continue to apply pressure to the blood drawing site until the bleeding stops.

[0003] For example, Chinese patent CN219962981U discloses a radial artery inflatable tourniquet, which stops bleeding for patients through an airbag and is fixed by a binding belt, making it easy to fix without damaging blood vessels and surrounding tissues, and can accurately adjust the inflation pressure of the airbag.

[0004] However, after the integrated airbag is inflated, the middle of the airbag becomes thicker and the edges are thinner, resulting in uneven pressure application. The thicker center portion is more difficult to accurately align with the wound, affecting the hemostasis effect. The device is also difficult to control the pressing time. Usually, in order to ensure that the pressing time is sufficient, the operator will choose to press overtime, causing the patient to use the device for too long, reducing the usage rate of the device.

[0005] Based on this, the utility model designs a compression hemostasis device to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the prior art, the utility model provides a compression hemostasis device.

[0007] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0008] A compression hemostasis device, comprising:

[0009] An inflatable belt, comprising a support bin, one side of which is open and a plurality of interconnected inflatable bags are evenly laid inside the support bin;

[0010] A binding assembly, comprising a binding belt, wherein two binding belts are respectively arranged on both sides of the support bin, and the distal ends of the two binding belts are respectively provided with a Velcro hook surface and a Velcro fleece surface; and

[0011] An installation box is installed inside which an air pump, a solenoid valve and a pressure sensor are installed. An air pipe is connected to the air outlet of the air pump, the other end of the air pipe is connected to the air bag, the solenoid valve is connected to the side wall of the air pipe through a connecting pipe, and the pressure sensor is connected to the side wall of the connecting pipe through a branch pipe. An operation panel electrically connected to the air pump, the solenoid valve and the pressure sensor respectively is installed on the outside of the installation box.

[0012] Furthermore, a timer is installed inside the installation box, and the timer is electrically connected to the operation panel.

[0013] Furthermore, a loudspeaker is installed inside the installation box, and the loudspeaker is electrically connected to the operation panel.

[0014] Furthermore, pads are provided at the opening of the support bin and the inner side of the binding belt.

[0015] Furthermore, one side of each of the inflatable bags facing the opening of the support compartment and the inner side of the binding belt are connected to the pad through Velcro.

[0016] The utility model has the following technical effects:

[0017] The utility model utilizes an air pump to inflate an inflatable belt through an air inflation tube. The inflated inflatable belt compresses the disinfection cotton and the blood collection site of the user to achieve a hemostasis effect. The blood collection site is compressed by multiple air bags to stop bleeding, so that the entire inflation and compression site is more uniform and the user's comfort is improved at the same time. The pressure sensor detects the pressure in the inflatable belt through a branch pipe, a connecting pipe and an inflatable pipe. After reaching a predetermined pressure intensity, the air pump is turned off to maintain a predetermined pressure in the inflatable belt, so that the device always presses the user according to the predetermined pressure, thereby ensuring the user's comfort and avoiding damage to the user caused by excessive pressure. After the pressing is completed, the operation panel opens the solenoid valve, and the gas in the inflatable belt is discharged from the solenoid valve through the inflatable pipe and the connecting pipe to complete the pressure relief, and the device is moved out to complete the hemostasis of the user's blood collection site.
