Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a brachial artery presser for clinical treatment. Background Art

[0002] In the clinical practice of cardiovascular medicine, interventional treatment techniques are widely used to diagnose and treat cardiovascular problems such as coronary artery disease. These techniques usually involve inserting a catheter through the femoral artery or radial artery to perform various operations, such as angiography, interventional stent placement, etc. With the completion of the interventional treatment, the doctor needs to remove the puncture needle, catheter or other interventional equipment from the artery, and the question that follows is how to effectively control the bleeding at the puncture site. At this time, effective compression of the brachial artery to stop bleeding becomes a crucial step.

[0003] Traditionally, hemostasis is performed by medical staff applying direct pressure with their fingers. However, this method has multiple limitations. First, manual compression requires medical staff to have extensive experience and skills to ensure that the pressure applied can effectively stop bleeding without causing tissue damage or blood flow blockage due to excessive compression. However, in actual operation, this manual method may not be effective due to fatigue, improper operation or negligence. In addition, manual compression requires medical staff to maintain a posture for a long time, which not only consumes human resources, but also takes up their time for other medical operations. Summary of the invention

[0004] The purpose of the present invention is to provide a brachial artery presser for clinical treatment, which can make the compression head further protrude while the fixing belt is tightened, thereby ensuring the compression effect.

[0005] In order to achieve the above technical objectives and the above technical effects, the present invention is implemented through the following technical solutions:

[0006] A brachial artery presser for clinical treatment, comprising a working part and a fixing belt, wherein the working part comprises a locking assembly and a compression assembly, one end of the fixing belt is detachably connected to the working part through a connector, and the other end is inserted into the working part and is wound around the locking assembly;

[0007] Furthermore, the locking assembly includes a ratchet gear and a transmission wheel, the fixing belt is provided with a ratchet bar and a transmission rack, the ratchet gear and the ratchet bar are adaptively meshed, and the transmission wheel and the transmission rack are adaptively meshed; one end of the fixing belt passes through the working part, around the locking assembly, and then passes out of the working part.

[0008] Furthermore, the transmission wheel and ratchet gear are each provided with a group, the ratchet gear is located beside the transmission wheel, the ratchet gear group is rotatably connected to the working part through a connecting shaft, and the working part is provided with a fixing button for fixing the rotation state of the connecting shaft; the connecting shaft is a hollow structure, and the transmission wheel is rotatably connected to the working part through a rotating shaft that penetrates the connecting shaft.

[0009] Furthermore, it also includes a bevel gear group, a transmission shaft, a driving gear, a driving rack, and an air cylinder. The rotating shaft drives the driving gear to rotate through the bevel gear group and the transmission shaft. The driving gear is meshed and connected with the driving rack. The head end of the driving rack penetrates into the air cylinder, and the head end is provided with a plunger adapted to the inner wall of the air cylinder; the air cylinder is connected to the compression assembly through a connecting pipe.

[0010] Furthermore, the compression assembly includes a compression head, with limit blocks on both sides of the compression head, an airbag on the rear side of the compression head, and the airbag is limited between the limit blocks on both sides and the compression head; the airbag is connected to the air cylinder through a connecting pipe.

[0011] Furthermore, a pressure sensor is provided between the compression head and the airbag, and the pressure sensor is electrically connected to a warning component provided on the working part, and the warning component is provided with a logic circuit, a buzzer component, and a light component.

[0012] Beneficial effects of the present invention:

[0013] The design of the fixing belt of the present invention achieves stable fixation through the meshing of the ratchet gear and the ratchet bar. Due to the one-way characteristic of the ratchet gear, it can prevent reverse sliding after the fixing belt reaches the required tightness, thereby ensuring that the fixing belt will not loosen during the compression process. This one-way meshing mechanism not only provides ease of operation, but also greatly improves the safety and stability of the fixing belt. In addition, the precise matching of the transmission wheel and the transmission rack allows the fixing belt to be tightened smoothly. This collaborative work ensures the stability of the applied pressure and avoids changes in the compression force caused by the displacement of the equipment.

[0014] The present invention combines the mechanical transmission system with the compression force adjustment, and converts the rotary motion into the linear motion of the plunger through the integrated design of the bevel gear set, the transmission shaft, the driving gear and the driving rack. Finally, the gas flow in the cylinder changes the pressure in the airbag through the connecting pipe, thereby realizing the automatic adjustment of the compression force. While the fixing belt is tightened, the compression head is further raised to ensure the compression effect of the compression head. The error and uncertainty caused by manual adjustment are reduced, the accuracy and consistency of the applied pressure are ensured, and it is suitable for the clinical needs of different patients.

[0015] The pressure sensor installed between the compression head and the airbag monitors the applied pressure in real time and provides feedback through the warning component of the working part. When the pressure exceeds the safe range, the warning component immediately issues an alarm through sound and light signals. This design provides an active safety guarantee mechanism. This function not only improves the operator's ability to control the applied pressure, but also reduces the risk of complications caused by excessive compression. The electrical connection design of the pressure sensor and the logic circuit, buzzer, and lighting component ensures the timeliness and accuracy of the response, which is an important safety supplement to the entire compression system.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Example 1

[0026] The present embodiment of the present invention provides a clinical treatment brachial artery presser, comprising a working part 1 and a fixing belt 2, wherein the working part 1 comprises a locking assembly 101 and a compression assembly 3, wherein one end of the fixing belt 2 is detachably connected to the working part 1 through a connector 203, and the other end of the fixing belt 2 is inserted into the working part 1 and is wound around and matched with the locking assembly 101;

[0027] In this embodiment, the locking assembly 101 includes a ratchet gear 102 and a transmission wheel 103, and the fixing belt 2 is provided with a ratchet bar 201 and a transmission rack 202, the ratchet gear 102 is adapted to mesh with the ratchet bar 201, and the transmission wheel 103 is adapted to mesh with the transmission rack 202; one end of the fixing belt 2 passes through the working part 1, wraps around the locking assembly 101, and then passes out of the working part 1.

[0028] The ratchet gear 102 meshes with the ratchet bar 201 on the fixing belt 2 to ensure that the fixing belt 2 will not slide in the reverse direction after being adjusted to the required tightness, thereby providing a reliable fixing effect. The fixing belt 2 passes through the ratchet gear 102 and the transmission wheel 103 and then passes out. When the fixing belt 2 is further tightened, the fixing belt 2 drives the transmission wheel 103 to rotate, and the ratchet gear 102 is fixed under the action of the fixing screw 1012; when the fixing belt 2 is tightened to a certain extent, the ratchet gear 102 presses against the ratchet bar 201 to fix the fixing belt 2; when the compression is completed, the ratchet gear 102 is turned to resume rotation, so that the fixing belt 2 can slide in the reverse direction, and the device is loosened.

[0029] In this embodiment, the transmission wheel 103 and the ratchet gear 102 are each provided with a group, and the ratchet gear 102 is located next to the transmission wheel 103. The ratchet gear 102 group is rotatably connected to the working part 1 through a connecting shaft 1011. The working part 1 is provided with a fixing screw 1012 for fixing the rotation state of the connecting shaft 1011; the connecting shaft 1011 is a hollow structure, and the transmission wheel 103 is rotatably connected to the working part 1 through a rotating shaft 1031 that penetrates the connecting shaft 1011.

[0030] It should be understood that during the tightening process of the fixed belt 2, the transmission rack 202 drives the transmission wheel 103 to rotate, the transmission wheel 103 drives the rotating shaft 1031 to rotate, the rotating shaft 1031 drives the transmission shaft 105 to rotate through the bevel gear set 104, one end of the transmission shaft 105 is connected to the bevel gear set 104, and the other end is fixed with a driving gear 106, the transmission shaft 105 drives the driving gear 106 to rotate, the driving gear 106 drives the meshing driving rack 107 to translate, and the end of the driving rack 107 is provided with a Some plungers 108 slide in the air cylinder 109, and the air cylinder 109 is connected with the air bag 303 provided in the compression component 3 through the connecting pipe 110. The air bag 303 is inflated under the action of the plunger 108. One end of the air cylinder 109 is connected with the connecting pipe 110, and the other end is provided with an air hole 111 near the inside. The plunger 108 returns to its position through the air hole 111, so that the air pressure in the air cylinder 109 is balanced, and the air bag 303 in the compression component 3 is deflated, so that the air cylinder 109 is filled with gas again for the next inflation.

[0031] In this embodiment, it also includes a bevel gear group 104, a transmission shaft 105, a driving gear 106, a driving rack 107, and an air cylinder 109. The rotating shaft 1031 drives the driving gear 106 to rotate through the bevel gear group 104 and the transmission shaft 105. The driving gear 106 is meshed and connected with the driving rack 107. The head end of the driving rack 107 penetrates into the air cylinder 109, and the head end is provided with a plunger 108 adapted to the inner wall of the air cylinder 109; the air cylinder 109 is connected to the compression component 3 through the connecting pipe 110.

[0032] It should be understood that the transmission shaft 105 is connected to the driving gear 106 through a bevel gear set 104. The rotation of the driving gear 106 is converted into linear motion through the driving rack 107 meshing therewith, thereby pushing the plunger 108 in the gas cylinder 109 to move. The movement of the plunger 108 directly affects the gas flow in the gas cylinder 109, changes the pressure in the air bag 303 through the connecting pipe 110, and realizes the adjustment of the pressure applied to the compression head 301.

[0033] In this embodiment, the compression assembly 3 includes a compression head 301, with limit blocks 302 on both sides of the compression head 301, and an airbag 303 on the rear side of the compression head 301, and the airbag 303 is limited between the limit blocks 302 on both sides and the compression head 301; the airbag 303 is connected to the air cylinder 109 through a connecting tube 110.

[0034] It should be understood that the compression component 3 is located at the front end of the working part 1 and is in direct contact with the patient's skin. The component includes a compression head 301, a limit block 302 and an airbag 303. The compression head 301 is the main component for applying pressure and is located between the limit blocks 302 to prevent lateral movement. The airbag 303 is arranged on the rear side of the compression head 301 and forms a closed space with the limit blocks 302. When the airbag 303 is inflated, it can apply appropriate pressure to the compression head 301. The airbag 303 is connected to the air cylinder 109 on the rear side through a connecting tube 110. The volume change of the air cylinder 109 directly affects the pressure in the airbag 303, thereby controlling the magnitude of the compression force.

[0035] In this embodiment, a pressure sensor is provided between the compression head 301 and the airbag 303 to monitor the magnitude of the applied pressure in real time. The pressure sensor is electrically connected to the warning component provided in the working part 1, and the warning component is provided with a logic circuit, a buzzer component, and a light component. When the pressure exceeds the safe range, the warning component will emit an audible and visual alarm to remind the operator to adjust the applied pressure in time.

[0036] Example 2

[0037] During cardiovascular interventions, such as coronary angiography or stent surgery, interventional devices are usually introduced into the patient's body through the femoral artery or radial artery. After the procedure, bleeding at the catheter removal site becomes a key issue. The brachial artery compressor plays an important role in this situation, ensuring effective bleeding by providing continuous, stable, and automated compression.

[0038] When using the compressor, you first need to conduct a comprehensive inspection of the device. Make sure all components, including the working part, fixing belt, compression component, locking and transmission system, are in good condition and clean. Confirm that the airbag has no leakage and the air cylinder and sensor are working properly, which is an important prerequisite for the effective operation of the device.

[0039] Once the equipment is ready, during the patient preparation process, the medical staff needs to let the patient lie flat on the operating table and stretch the arm to be operated in a convenient position. At this time, it is recommended that the blood and disinfectant at the puncture site have not been completely cleaned to more clearly locate the arterial puncture site and avoid possible infection risks.

[0040] The working part integrates the locking component and the compression component. The fixing belt is used to firmly tie the presser to the patient's arm. One end of the fixing belt is connected to the working part through a detachable connector, and the other end passes through the working part and cooperates with the locking component to achieve efficient fixation. The locking component involves the cooperation of the ratchet gear and the transmission wheel. The fixing belt is provided with a ratchet bar and a transmission rack. The ratchet gear meshes with the ratchet bar to prevent the fixing belt from sliding in the opposite direction after adjusting to the required tightness, and the transmission wheel meshes with the transmission rack to help tighten the fixing belt.

[0041] The other end of the fixing belt passes through the working part, around the ratchet gear and the transmission wheel, and then passes out. By tightening the fixing belt, the transmission wheel can be driven to rotate, and the ratchet gear is kept fixed by the fixing screw. When the fixing belt is appropriately tight, the ratchet gear presses against the ratchet bar to effectively limit the fixing belt. After the pressure is applied, the ratchet gear is unlocked by turning the fixing screw, allowing the fixing belt to slide in the reverse direction, thereby easily loosening the device.

[0042] The transmission wheel drives the bevel gear set through the rotating shaft, which in turn drives the transmission shaft to rotate. A driving gear is connected to one end of the transmission shaft, and a driving rack is fixed to the other end. The head of the driving rack enters and slides in the cylinder, and the cylinder is connected to the air bag in the compression assembly through a connecting pipe. In this process, the rotation of the transmission shaft is converted into linear motion through the bevel gear set, pushing the driving rack to translate, driving the plunger at its end to move in the cylinder. The movement of the plunger directly affects the flow of gas in the cylinder, thereby changing the pressure in the air bag. For example, when the plunger is pushed forward, the gas in the cylinder enters the air bag through the connecting pipe, inflating the air bag, and applying appropriate pressure to the patient through the compression head. Once the plunger is returned to its position, the cylinder balances the internal air pressure through the air hole, allowing the air bag to deflate and be ready for the next use.

[0043] When the equipment is safely in place, the operator controls the air intake of the air cylinder through the transmission of the rotating shaft and the bevel gear set, and then inflates the airbag. The compression head is limited by the limit blocks on both sides to prevent lateral movement. The airbag is located on the rear side of the compression head, and the limit blocks ensure the stability of the pressure when the airbag is inflated. After inflation, the airbag expands and pushes the compression head to apply the preset pressure to the brachial artery puncture point. At this time, the pressure sensor begins to monitor the actual applied pressure in real time. If the pressure is too high or too low, the monitoring system will send out an audible and visual alarm through the built-in warning component to remind the operator to make appropriate adjustments. Such a real-time monitoring mechanism ensures safety and avoids blood flow blockage caused by excessive pressure or hemostasis failure caused by insufficient pressure.

[0044] During the operation of the device, the operator should keep an eye on the patient. Ask the patient if he feels discomfort caused by excessive compression and be ready to adjust the pressure at any time. This process is both a way to stop bleeding and a real-time test of the device.

[0045] After waiting for about 15 to 30 minutes, gradually reduce the pressure according to the postoperative hemostasis rules. Loosen the fixing belt through the locking assembly to gradually release the pressure on the artery. This gradual release helps to detect whether the puncture site is completely healed and prevent recurrence of bleeding.

[0046] Finally, before removing the device, a final inspection of the puncture site is required to ensure that it is healing well and there is no sign of bleeding. After the compressor is used, it needs to be thoroughly cleaned and disinfected for subsequent use.
