Description

Technical Field

[0001] This utility model relates to the field of medical device testing technology, specifically to an implantable pacemaker pressure cycle tester. Background Technology

[0002] Implantable pacemakers are important medical devices used to treat cardiac rhythm disorders such as bradycardia. They stimulate the heart by delivering electrical pulses to maintain a normal rhythm and pumping function, thereby greatly improving patients' quality of life and saving many lives. With the aging population and the rising incidence of cardiovascular diseases, the clinical demand for implantable pacemakers is constantly increasing, and their application is becoming more and more widespread. After being implanted in the human body, the pacemaker is subjected to periodic pressure changes with each heartbeat. These pressure changes may affect the pacemaker's packaging structure, internal circuitry, and electrode connections. Long-term accumulation may lead to problems such as component fatigue, seal failure, and circuit malfunction, which can affect the normal operation of the pacemaker and even endanger the patient's life. Therefore, pressure cycle testing equipment is often used to test its performance.

[0003] Chinese Utility Model Patent Publication No. CN 219016464 U discloses a testing device for a leadless pacemaker. This device uses a ring-shaped conductive end connection mechanism to clamp the proximal ring electrode of the leadless pacemaker, preventing damage to its outer surface. The ring-shaped conductive end connection mechanism drives the electrode conductive end connection mechanism, facilitating clamping of the leadless pacemaker and preventing it from detaching during testing, thus ensuring accurate results. However, while this testing device can perform tests, it is not convenient for pressure adjustment, resulting in limited versatility during testing. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an implantable pacemaker pressure cycle tester, which can effectively solve the problems in the prior art.

[0005] The technical solution adopted by this utility model is: an implantable pacemaker pressure cycle tester, including a base plate, a test canister fixedly installed on the base plate, and a controller electrically connected to the test canister. A drain pipe is provided through the test canister on the side near the base plate. A limiting component is fixedly installed near the outer wall of the test canister. An extension plate is fixedly installed at the other end of the test canister away from the base plate. A top cover adapted to the limiting component is provided at the other end of the test canister away from the base plate. A connecting end and a connecting wire are provided at the end of the test canister near the base plate. The other end of the connecting wire away from the test canister is connected to the controller.

[0006] The limiting assembly includes a limiting block one fixedly installed on the outer wall of the test tank. A rotating rod is rotatably installed at the other end of the limiting block one away from the test tank. A threaded rod is fixedly installed near the center line of the rotating rod. A pad block and a limiting block two are threadedly connected to the other end of the threaded rod away from the limiting block one.

[0007] Preferably, a hook is fixedly installed at the other end of the limiting block away from the pad block, and the hook has a semi-circular cross-section.

[0008] With the above technical solution, through the cooperation of the limiting block 2, the pad block and the hook, when the test piece is placed inside the test tank, the limiting block 2 can be rotated by the hook, and then the pad block and the limiting block 2 can be screwed into the threaded rod. Then the pad block can press against the top cover, and then the limiting block 2 and the top cover can be locked together, which can prevent pressure leakage during pressure testing.

[0009] Preferably, the pad is in contact with the top cover, and the pad and the limiting block 2 penetrate the extension plate and extend to the top of the top cover.

[0010] Through the above technical solution, the design of the pad increases the contact area between the limiting block and the top cover when the limiting block is screwed in, preventing it from easily shifting and causing pressure loss, which would affect its normal use.

[0011] Preferably, an extension port is fixedly installed at one end of the top cover near the center and on the side away from the test tank, and a screw cap is threaded to the outer edge of the extension port.

[0012] With the above technical solution and the design of the extension port, when inserting the test piece, the cap can be unscrewed, and then the test piece can be inserted through the extension port. The above operation can then be repeated to lock the cap, which facilitates quick insertion of the test piece. The top cover and the cap can be removed and removed according to the actual situation, thereby improving its versatility in use.

[0013] Preferably, the top cover has an inlet at the end away from the test tank, and there are two identical inlets, both of which penetrate the top cover and communicate with the test tank.

[0014] Through the above technical solution, the design of the inlet allows test water to be injected into one inlet, and then a booster pump can be connected to another inlet to pressurize the inside of the test tank. It can also be connected to detect electrical signals from devices such as pacemakers, thus facilitating testing.

[0015] Preferably, a solenoid valve is provided at the outer edge of the drain pipe away from the test tank, handles are fixedly installed on both sides of the controller away from the center line, and a test tube and a test gauge are provided at the other end of the top cover away from the bottom plate.

[0016] Through the above technical solution and the design of the solenoid valve, the drain pipe can be opened and closed by the solenoid valve after the test is completed and during the test, so as to facilitate the drainage of the test tank. In conjunction with the test tube and test gauge, the internal pressure value can be easily observed.

[0017] Preferably, the controller has a display screen at one end near the handle, and an operation button is located at the center of the two display screens.

[0018] Through the above technical solution and the design of the controller, the pressure value inside the test tank can be viewed through the display screen and operation buttons, which facilitates the understanding of data changes and thus improves the versatility of use.

[0019] Compared with the prior art, this utility model provides an implantable pacemaker pressure cycle testing device, which has the following beneficial effects:

[0020] 1. This implantable pacemaker pressure cycle tester, through its inlet design, allows for the injection of test water into one inlet, followed by the connection of a booster pump to another inlet to pressurize the test tank. This enables adjustment of the internal pressure value and increases the versatility of testing. Furthermore, with the extension port design, when inserting a test piece, the cap can be unscrewed, and the test piece can be inserted through the extension port. The above operation can then be repeated to lock the cap, facilitating quick insertion of test pieces. The top cover and cap can be removed and replaced as needed, further enhancing its versatility in use.

[0021] 2. This implantable pacemaker pressure cycle tester, through the cooperation of limit block two, pad block and pull hook, when the test piece is placed inside the test canister, limit block two can be rotated by pull hook, and then the pad block and limit block two are screwed into the threaded rod, which can then make the pad block squeeze the top cover, and then limit block two and the top cover are locked together, which can prevent pressure leakage during pressure testing.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1: As Figure 1-7 As shown, the present invention provides an implantable pacemaker pressure cycle tester, including a base plate 1, a test canister 2 fixedly installed on the base plate 1, and a controller 15 electrically connected to the test canister 2. A drain pipe 3 is provided through the test canister 2 on the side near the base plate 1. A limit component 5 is fixedly installed near the outer wall of the test canister 2. An extension plate 6 is fixedly installed at the other end of the test canister 2 away from the base plate 1. A top cover 7 adapted to the limit component 5 is provided at the other end of the test canister 2 away from the base plate 1. A connecting end 13 and a connecting line 14 are provided at the end of the test canister 2 near the base plate 1. The other end of the connecting line 14 away from the test canister 2 is connected to the controller 15.

[0032] The limiting assembly 5 includes a limiting block 501 fixedly installed on the outer wall of the test tank 2. A rotating rod 502 is rotatably installed at the other end of the limiting block 501 away from the test tank 2. A threaded rod 503 is fixedly installed near the center line of the rotating rod 502. A pad 504 and a limiting block 505 are threadedly connected to the other end of the threaded rod 503 away from the limiting block 501.

[0033] Specifically, a hook 506 is fixedly installed at the other end of the limiting block 505 away from the pad 504. The hook 506 has a semi-circular cross-section. The advantage is that, through the cooperation of the limiting block 505, the pad 504 and the hook 506, when the test piece is placed inside the test tank 2, the limiting block 505 can be rotated by the hook 506, which then causes the pad 504 and the limiting block 505 to be screwed into the threaded rod 503. Subsequently, the pad 504 can press the top cover 7, and then the limiting block 505 and the top cover 7 can be locked together, which can prevent pressure leakage during pressure testing.

[0034] Specifically, the pad 504 contacts the top cover 7. The pad 504 and the second limiting block 505 pass through the extension plate 6 and extend to the top of the top cover 7. The advantage is that, through the design of the pad 504, when the second limiting block 505 is screwed in, the contact surface between the second limiting block 505 and the top cover 7 can be increased, preventing it from easily shifting, which would cause it to depressurize and affect its normal use.

[0035] Specifically, an extension port 9 is fixedly installed on one end of the top cover 7 near the center and on the side away from the test tank 2. A screw cap 10 is threadedly connected to the outer edge of the extension port 9. The advantage is that, through the design of the extension port 9, when the test piece is inserted, the screw cap 10 can be unscrewed, and then the test piece can be inserted through the extension port 9. The above operation can be repeated to lock the screw cap 10, which facilitates quick insertion of the test piece. The top cover 7 and the screw cap 10 can be removed and removed according to the actual situation, thereby improving its versatility in use.

[0036] Example 2: Figure 2-7 As shown, this is an improvement on the previous embodiment.

[0037] Specifically, an inlet 8 is provided at the other end of the top cover 7 away from the test tank 2. There are two identical inlets 8, both of which penetrate the top cover 7 and communicate with the test tank 2. The advantage is that, through the design of the inlets 8, test water can be injected into one inlet 8, and then a booster pump can be connected to the other inlet 8 to pressurize the inside of the test tank 2. It can also be connected to detect the electrical signals of devices such as pacemakers, thus facilitating testing.

[0038] Specifically, a solenoid valve 4 is installed on the outer edge of the drain pipe 3 away from the test tank 2, and handles 16 are fixedly installed on both sides of the controller 15 away from the center line. A test tube 11 and a test gauge 12 are installed on the other end of the top cover 7 away from the bottom plate 1. The advantage is that, through the design of the solenoid valve 4, the drain pipe 3 can be opened and closed by the solenoid valve 4 after the test is completed and during the test, so as to facilitate the drainage of the test tank 2. With the help of the test tube 11 and the test gauge 12, the internal pressure value can be easily observed.

[0039] Specifically, a display screen 17 is provided at one end of the controller 15 near the handle 16, and an operation button 18 is provided at the center of the two displays 17. The advantage is that, through the design of the controller 15, the pressure value inside the test tank 2 can be understood through the display screen 17 and the operation button 18, which makes it easier to understand the changes in its data and thus improves the versatility of use.

[0040] Working Principle: During use, the design of inlet 8 allows test water to be injected into one inlet 8, and a booster pump can be connected to the other inlet 8 to pressurize the inside of the test tank 2. It can also be connected to detect electrical signals from devices such as pacemakers, facilitating testing. The design of extension port 9 allows the cap 10 to be unscrewed when inserting a test piece, and the test piece can then be inserted through extension port 9. Repeating this process locks the cap 10, facilitating quick insertion of test pieces. The top cover 7 and cap 10 can be removed depending on the situation, increasing its versatility. The design of pad 504 increases the contact area between the limiting block 505 and the top cover 7 when the limiting block 505 is screwed in, preventing displacement and pressure loss that could affect normal use. 05. The cooperation of pad 504 and hook 506: When the test piece is placed inside the test tank 2, the limit block 505 can be rotated by hook 506, which then causes pad 504 and limit block 505 to be screwed into threaded rod 503. Subsequently, pad 504 can press the top cover 7, and limit block 505 can be locked with the top cover 7, which can prevent pressure leakage during pressure testing. Through the design of solenoid valve 4, the drain pipe 3 can be opened and closed through solenoid valve 4 after the test is completed and during the test, which facilitates drainage of test tank 2. With the help of test tube 11 and test gauge 12, the internal pressure value can be easily observed. Through the design of controller 15, the internal pressure value of test tank 2 can be understood through display screen 17 and operation button 18, which can facilitate understanding of its data changes and improve the versatility of use.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
