Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an electronic radial artery compressor. Background Art

[0002] After the radial artery is punctured, a radial artery compressor is required to compress and stop bleeding to prevent bleeding at the puncture site or subcutaneous hematoma. The working principle of the radial artery compressor is based on the principle of hemodynamics. When the pressure on the radial artery wall is equal to the continuous pressure of the blood flow, the blood flow will be interrupted to achieve the hemostasis effect.

[0003] Conventional radial artery compressors rely on the experience and subjective judgment of medical staff to control the pressure at the radial artery puncture point, which often leads to excessive or insufficient pressure at the puncture point. For example, excessive pressure may cause radial artery occlusion, which may cause irreparable trauma to the patient, and the radial artery cannot be re-examined. Inadequate pressure may cause bleeding or subcutaneous hematoma at the puncture point, causing limb pain, high error, and affect the hemostasis effect.

[0004] Furthermore, the patent number is CN202122534594.2, which discloses an intelligent hemostasis instrument, including: an inflatable cuff; a pressure sensor, the pressure sensor is arranged on the inner surface of the inflatable cuff, and is used to detect the human pulse beating signal; the device body, the device body includes a device shell and an air pump and a controller arranged in the device shell, the air pump is connected to the inflatable cuff, and the controller is electrically connected to the pressure sensor and the air pump, and is used to control the air pump to stop inflating when the pressure sensor cannot detect the pulse beating signal. According to the intelligent hemostasis instrument provided by the embodiment of the utility model, a pressure sensor is provided in the inflatable cuff. When in use, the pressure sensor can be used to detect the pulse beating signal. When the inflatable cuff is tied to the patient's limb, when the pressure sensor cannot detect the pulse beating signal, it means that the blood flow is completely blocked. At this time, the controller controls the inflation pump to stop inflation. In this way, it is possible to automatically complete inflation and achieve the effect of blood flow blocking without relying on experience or incision observation. The operation is more convenient and simple, which is conducive to blood flow blocking and surgical operations.

[0005] However, the following technical problems still exist:

[0006] 1. The material of the inflatable cuff is soft and there is no positioning component. During the hemostasis process, the bleeding at the puncture point is easy to stain the inflatable cuff, resulting in reduced friction between the inflatable cuff and the puncture point, which is prone to relative displacement, and then drives the pressure sensor to shift. Since there is more than one radial artery on the forearm, the detection error is high, affecting the hemostasis effect;

[0007] 2. The inner wall of the inflatable cuff is in direct contact with the patient's puncture point, and blood can easily contaminate the inflatable cuff, making cleaning and disinfection difficult. Utility Model Content

[0026] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0027] like Figure 1 , 2 As shown, the utility model provides an electronic radial artery compressor, comprising a cuff body 1, a pulse sensor 9, and a compression structure and a limiting structure arranged on the pressurized outer wall surface of the cuff body 1; the pulse sensor 9 is arranged corresponding to the compression structure; during the inflation and pressurization process of the cuff body 1, the compression structure is driven to form a compression effect on the puncture point of the radial artery; the limiting structure is arranged on at least one side of the compression structure, for keeping the relative position of the compression structure and the puncture point of the radial artery unchanged during the inflation and pressurization process.

[0028] The utility model sets a compression structure and a limiting structure on the pressurized outer wall surface of the cuff body 1. During the inflation and pressurization process, the cuff body 1 drives the compression structure to compress the puncture point of the radial artery. At the same time, the pulse sensor 9 detects the pulse of the radial artery in real time until the pulse of the radial artery cannot be detected. The cuff body 1 stops inflating and maintains the current pressurization state to achieve hemostasis of the puncture point of the radial artery. And because the limiting structure is set on one side of the compression structure, even if the puncture point bleeds, the limiting structure can fit tightly with the skin around the puncture point, and can keep the relative position of the compression structure and the puncture point of the radial artery unchanged during the inflation and pressurization process, ensuring the accuracy of the detection process of the pulse sensor 9 and the real-time feedback response, and the hemostasis effect is good.

[0029] Furthermore, a waterproof surface layer 102 is added to the pressurized outer wall surface of the cuff body 1, and an installation cavity is formed between the waterproof surface layer 102 and the pressurized outer wall surface of the cuff body 1 for installing the compression structure, the limit structure and the pulse sensor 9. The connecting wire of the pulse sensor 9 is placed in the installation cavity to avoid being exposed.

[0030] As an optional embodiment, the compression structure includes a compression part 2 and a disposable silicone sleeve 3, the compression part 2 is arranged on the pressurized outer wall surface of the cuff body 1 and protrudes from the pressurized outer wall surface of the cuff body 1, the outer periphery of the compression part 2 is provided with an annular protrusion 201, and the disposable silicone sleeve 3 has a groove adapted to the annular protrusion 201.

[0031] Furthermore, the first end of the compression portion 2 is adhered and fixed to the pressurized outer wall surface of the cuff body 1 , and the second end thereof passes through the waterproof surface layer 102 and extends to the outside.

[0032] During the inflation and pressurization process of the cuff body 1, the compression part 2 is driven to drive the disposable silicone sleeve 3 to compress the puncture point of the radial artery. The disposable silicone sleeve 3 is in direct contact with the puncture point. Since the disposable silicone sleeve 3 is a disposable item and is used by one person once, cross infection between patients can be effectively prevented.

[0033] The cuff body 1 is sterilized and disinfected according to medical standards to ensure safety in use.

[0034] As an optional implementation, the pressing part 2 has a receiving cavity for placing the pulse sensor 9 to improve the detection sensitivity of the pulse sensor 9. And the closed end of the pressing part 2 is close to the disposable silicone sleeve 3.

[0035] As an optional implementation, there is at least one limiting structure, which includes a limiting portion 4 and a limiting block 5. The limiting portion 4 is arranged on the pressurized outer wall surface of the cuff body 1 and protrudes from the pressurized outer wall surface of the cuff body 1. The limiting portion 4 has a limiting groove 401, and the opening end of the limiting groove 401 faces the patient's skin. The limiting block 5 is snap-fitted with the limiting groove 401, and the limiting block 5 protrudes from the opening end of the limiting groove 401.

[0036] Furthermore, the number of the limiting structures can be set to one, two or more according to usage requirements.

[0037] The stopper 5 is made of silicone material, which can be slightly deformed and fit the skin better. Since the stopper 5 is detachably connected to the stopper groove 401, the stopper 5 can be designed to be disposable or non-disposable according to the use requirements.

[0038] During the inflation and pressurization process, the cuff body 1 drives the compression part 2 to drive the disposable silicone sleeve 3 to form a compression effect on the puncture point of the radial artery. At the same time, the limiting part 4 is driven to drive the limiting block 5 to fit closely with the patient's skin. The contact between the limiting block 5 and the patient's skin can increase the friction force to reduce the relative displacement between the compression part 2 and the puncture point, thereby ensuring the accuracy of the detection process of the pulse sensor 9 and the real-time feedback response.

[0039] As an optional implementation, the air inlet of the cuff body 1 is connected to the air pump 7 through the air inlet pipeline 6, and an electronic deflation valve 8 is provided at the air outlet of the cuff body 1. The specific structure of the inflation and deflation of the cuff body 1 adopts the existing technology, which will not be described in detail.

[0040] As an optional implementation, a controller is further included, and the controller is electrically connected to the pulse sensor 9, the air pump 7 and the electronic deflation valve 8. The specific circuit connection relationship between the controller and the pulse sensor 9, the air pump 7 and the electronic deflation valve 8 is prior art and will not be described in detail here.

[0041] When in use, the controller controls the air pump 7 to pump air into the cuff body 1, driving the compression part 2 to compress the puncture point of the radial artery. At the same time, the pulse sensor 9 detects the pulse of the radial artery in real time until the pulse of the radial artery is no longer detected, and then feeds back to the controller. The controller controls the air pump 7 to stop inflating, and the cuff body 1 maintains the current pressurized state.

[0042] When the cuff body 1 needs to be depressurized, the controller controls the electronic degassing valve 8 to open to discharge the gas in the inflation cavity 101 of the cuff body 1 .

[0043] As an optional implementation, a pressure sensor is provided on the cuff body 1 for detecting the gas pressure in the inflation cavity 101 of the cuff body 1 , and the pressure sensor is electrically connected to the controller.

[0044] During the pressurization or depressurization process of the cuff body 1, the gas pressure of the inflation cavity 101 of the cuff body 1 is monitored in real time by the pressure sensor and fed back to the controller. The controller controls the air pump 7 or the electronic depressurization valve 8 to keep the pressurization rate or depressurization rate of the cuff body 1 at the preset rate value to ensure safety and stability in use.

[0045] As an optional implementation, a buzzer is provided on the cuff body 1 for broadcasting a sound reminder alarm, and the buzzer is electrically connected to the controller.

[0046] Since compression and hemostasis need to be maintained on the puncture point for 6 to 8 hours after the puncture, the compression and hemostasis time is preset on the controller. When the preset time is reached, the controller controls the buzzer to broadcast a sound to remind medical staff.

[0047] As an optional embodiment, the inner diameter of the cuff body 1 is adjustable.

[0048] Furthermore, the cuff body 1 is a long strip structure, a Velcro 10 is provided on the outer wall surface of the first end of the cuff body 1, and a Velcro 11 is provided on the inner wall surface of the second end of the cuff body 1. By adjusting the relative positions of the Velcro 11 and the Velcro 10, the inner diameter of the cuff body 1 can be adjusted to adapt to patients of different body shapes.
