Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a digital display compression hemostat. Background Technology

[0002] Radial artery hemostats, as common medical devices, play an indispensable role in surgery. They work by applying pressure to the artery to control blood flow. During surgery, the surgeon makes a puncture in the patient's wrist, inserts a catheter into the radial artery, and then secures the hemostatic device of the radial artery hemostat at the puncture site. The surgeon can then gently remove the catheter; at this point, the hemostatic device of the radial artery hemostat applies appropriate pressure to the puncture site, thereby controlling bleeding.

[0003] Radial artery hemostats use pressure to stop bleeding at the puncture site on the patient's wrist. In existing radial artery hemostats, the control of hemostatic pressure mainly relies on the patient's sensation. However, in this state, patients often exhibit greater tolerance and compliance for safety reasons, resulting in excessively high pressure values ​​and increased patient discomfort. Conversely, for some patients lacking medical knowledge and with poor tolerance, the pressure value may be too low, leading to bleeding from the puncture site. Therefore, we propose a digital display pressure hemostat to address these issues. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a digital display compression hemostat.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The pressurization module includes a connecting sleeve fixedly connected to the buckle plate, and a rotating sleeve rotatably connected to the connecting sleeve. The rotating sleeve has an internal thread, and a pressure rod is connected to the internal thread of the rotating sleeve. The lower end of the pressure rod is slidably connected to the connecting sleeve. A pressure plate is fixedly connected to the lower end of the connecting sleeve, and a pressure sensor is installed inside the pressure plate. The pressure sensor is electrically connected to the electronic control module. A rubber bladder is embedded in the pressure plate, and one end of the rubber bladder is connected to a drain pipe. A solenoid valve is installed on the drain pipe, and the solenoid valve is electrically connected to the electronic control module.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention uses a pressure module and a rotating sleeve with a pressure rod to apply pressure to the patient's puncture site to stop bleeding. A rubber bladder replaces the spring to provide elasticity and improve patient comfort. After hemostasis is achieved at the puncture site, the electronic control module controls the solenoid valve to drain the liquid from the rubber bladder, reducing the pressure of the pressure plate on the patient's wrist and initially ending the entire compression hemostasis process.

[0015] This invention, by setting up an electronic control module, can, on the one hand, use a pressure sensor to monitor the pressure of compression for hemostasis and display it on a display screen, and on the other hand, use a controller to time it. After a certain period of compression for hemostasis, the solenoid valve is automatically opened to reduce the pressure of the pressure plate on the patient's wrist, making the patient feel more comfortable.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-3 A digital display compression hemostat includes a buckle plate 1, a strap 2 is provided on the buckle plate 1, a pressure module is provided on the buckle plate 1, and an electronic control module is provided on the buckle plate 1.

[0022] The pressurization module includes a connecting sleeve 3 fixedly connected to the buckle plate 1, and a rotating sleeve 4 rotatably connected to the connecting sleeve 3. The rotating sleeve 4 has an internal thread 5, and a pressure rod 6 is connected to the internal thread 5 of the rotating sleeve 4. The lower end of the pressure rod 6 is slidably connected to the connecting sleeve 3. A pressure plate 7 is fixedly connected to the lower end of the connecting sleeve 3, and a pressure sensor is provided inside the pressure plate 7. The pressure sensor is electrically connected to the electronic control module. A rubber bladder 8 is embedded in the pressure plate 7, and one end of the rubber bladder 8 is connected to a drain pipe 9. A solenoid valve 10 is provided on the drain pipe 9, and the solenoid valve 10 is electrically connected to the electronic control module.

[0023] In this design, a rubber bladder 8 replaces the traditional compression spring. The elasticity of the bladder 8 increases the elastic variable, thereby improving patient comfort while ensuring effective hemostasis. After the puncture procedure, medical staff place the hemostat on the patient's wrist and align the pressure plate 7 with the puncture point. The staff then rotates the selection panel, using the rotating sleeve 4 to drive the pressure rod 6 downwards, applying pressure to the patient's wrist with the pressure plate 7. Based on the electronic control module, pressure sensor, and the patient's blood pressure data, the pressure of the pressure plate 7 on the patient's wrist is adjusted to a suitable range, ensuring hemostasis while minimizing patient discomfort. After a certain period of hemostasis, the electronic control module opens the solenoid valve 10, allowing the liquid inside the rubber bladder 8 to drain through the drainage tube 9, reducing the pressure of the pressure plate 7 on the patient's wrist. The patient and medical staff can then observe the puncture point. If bleeding continues, the pressure of the pressure plate 7 can be increased again. If there is no bleeding, the entire hemostat is removed after a brief observation period.

[0024] Furthermore, the electronic control module includes a housing 11 fixedly connected to the buckle plate 1. The housing 11 is provided with a receiving chamber 12, and a piston 13 is slidably connected in the receiving chamber 12. The receiving chamber 12 is connected to the drain pipe 9. A push rod 14 is fixedly connected to the side of the piston 13 away from the drain pipe 9. A signal processor and a controller are also fixedly connected in the housing 11. The signal processor is electrically connected to the pressure sensor, and the controller is electrically connected to the solenoid valve 10. A display 15 and control buttons 16 are also embedded in the housing 11.

[0025] In this design, by setting up piston 13 in conjunction with push rod 14, the liquid in the receiving chamber 12 can be quickly injected into the rubber bladder 8 when bleeding is still observed at the patient's puncture site, thereby quickly pressurizing the pressure plate 7 without adjusting its position. The display 15 can visually display the specific pressure data, making it convenient for medical personnel to adjust the pressure during hemostasis. In addition, the controller includes a timing function. When used with control button 16, the compression hemostasis time can be adjusted and timed according to the patient's own blood clotting function, blood pressure and other parameters, making it convenient for medical personnel and patients to remove the hemostat after the specified hemostasis time has been reached.

[0026] Furthermore, the buckle plate 1 is also provided with a soft pad 17, and a pulse sensor is provided inside the soft pad 17. The pulse sensor is electrically connected to the signal processor.

[0027] The soft pad 17, in conjunction with the pulse sensor, can monitor the patient's heart rate, obtain more accurate physical data, and assist in postoperative observation.

[0028] Furthermore, a buzzer alarm is embedded on one side of the housing 11, and the buzzer alarm is electrically connected to the controller;

[0029] Using a buzzer alarm can provide a more noticeable reminder to patients and medical staff when the designated hemostasis time is reached.

[0030] Furthermore, the pressure plate 7 includes a support frame 71, an arc-shaped plate 72 is slidably connected inside the support frame 71, and a limit sleeve 73 is provided inside the support frame 71. The rubber bladder 8 is located inside the limit sleeve 73 and abuts against the arc-shaped plate 72.

[0031] In this design, the limiting sleeve 73 is used to limit the position of the rubber balloon 8 and restrict the deformation range of the rubber balloon 8, ensuring the pressure effect of the pressure plate 7 on the puncture point at the patient's wrist, while avoiding the situation where the arc plate 72 tilts after the rubber balloon 8 deforms, resulting in uneven pressure of the arc plate 72 on the puncture point.

[0032] Furthermore, the curved plate 72 is made of transparent PC or ABS material, and a pressure pad is provided on the curved plate 72.

[0033] Using transparent PC or ABS material allows medical staff or patients to observe bleeding at the puncture point on the patient's wrist more quickly after the solenoid valve 10 is activated, and pressure can be increased in time to prevent continuous bleeding from the puncture point, thus reducing observation time. At the same time, it eliminates the need to move the arc plate 72 to a position away from the puncture point for observation.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
