Technical Field

[0001] The utility model relates to the technical field of cardiac pacemakers, and particularly relates to an anti-shock test device for an implantable cardiac pacemaker. Background Technique

[0002] An implantable cardiac pacemaker is an electronic therapeutic instrument implanted in the human body based on the treatment of cardiac dysfunction. It emits electrical pulses provided by a battery through a pulse generator, and through the conduction of wire electrodes, stimulates the myocardium contacted by the electrodes, causing the heart to beat and contract. During the production process of an implantable cardiac pacemaker, it needs to be tested, and the anti-shock test is one of them to avoid the occurrence of faults when the cardiac pacemaker is in use.

[0003] Chinese Patent Publication No.: CN117031172A, discloses: an implantable cardiac pacemaker test system. As an integrated test network tooling, the implantable cardiac pacemaker and related test equipment are all pre-connected to the test system in advance. For different preset test items, the test load and test equipment connection inside the test system are automatically changed correspondingly. However, this implantable cardiac pacemaker test system is not convenient for performing shock tests on the cardiac pacemaker, which easily leads to a large limitation of the overall system, and is not convenient for playing a guiding role, easily resulting in poor stability and impact accuracy during the test, and poor practicability. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide an anti-shock test device for an implantable cardiac pacemaker, which can effectively solve the problems in the prior art.

[0005] The technical solution adopted by the utility model is: an anti-shock test device for an implantable cardiac pacemaker, including a base, a mounting frame is fixedly installed on the top of the base, a limiting seat and a display member are fixedly installed on one side of the mounting frame, and a sliding column with one end fixedly installed on the base and the other end fixedly installed on the mounting frame, positioning plates for positioning are fixedly installed on both sides of the mounting frame, a support plate with a "U" - shaped cross - section for support is arranged on one side of the mounting frame close to the center point, a fixing plate and a cover plate inserted into the positioning plate are fixedly installed on the side of the support plate close to the positioning plate, an impact component slidably connected to the sliding column is fixedly installed on the top of the mounting frame, and a placing plate is arranged on the top of the support plate and at one end of the mounting frame close to the center line;

[0006] The impact assembly includes a first cylinder located at the top of the mounting bracket, an extension seat one fixedly mounted on the output shaft of the first cylinder, a second cylinder fixedly mounted on the end of the extension seat one near the first cylinder, an extension seat two fixedly mounted on the output shaft of the second cylinder, and a contact plate provided on the end of the extension seat two near the base.

[0007] Preferably, the extension seat has first extension ears fixedly installed on both sides, and a sliding hole is opened through the top of the first extension ear. The extension seat is slidably connected to the sliding column through the sliding hole on the first extension ear.

[0008] Through the above technical solution, the design of the first extension ear allows the first extension ear to slide at the sliding post when the stroke of the first cylinder is adjusted, which can guide it and prevent it from shifting during the impact process, thereby improving the stability during the test.

[0009] Preferably, the first extension seat is fixedly installed with a limiting bracket with an "L"-shaped cross section that abuts against the second cylinder on the side near the first cylinder, and the second extension seat is fixedly installed with second extension ears that are slidably connected to the sliding column on both sides, and a sliding sleeve that is slidably connected to the sliding column is fixedly installed at the end of the second extension ear near the base.

[0010] Through the above technical solution, and through the design of the second cylinder and the second extension ear, when the stroke of the second cylinder is adjusted, the sliding column, in conjunction with the sliding sleeve and the second extension ear, can guide the second cylinder, thereby further improving its stability and displacement accuracy.

[0011] Preferably, the second extension seat has a mounting groove on the side near the base, and the second extension seat has a contact plate through the mounting groove.

[0012] Through the above technical solution, the contact plate can be installed on the impact assembly by the cooperation of the mounting groove and the contact plate. Then, when the first cylinder and the second cylinder push the contact plate to move, the contact plate can be impacted with the implantable pacemaker placed on the limiting plate.

[0013] Preferably, the positioning plate has a positioning groove at the end away from the base, the cover plate has a positioning sleeve that matches the positioning groove fixedly installed at the end near the positioning plate, the top of the cover plate has a positioning hole, and a positioning bolt is threaded between the positioning plate and the cover plate.

[0014] Through the above technical solution, by designing the positioning groove and positioning sleeve, when installing the support plate, the positioning sleeve can be inserted into the positioning groove. With the help of the mounting bracket, it can facilitate the quick installation of the support plate and also provide support for the placement plate, thereby improving its practicality.

[0015] Preferably, the placement plate has a through-hole on the side near the mounting bracket, and a positioning post and a sensor body electrically connected to the display are inserted and installed on the inner surface of the placement slot. A limit plate is provided on the side of the placement plate away from the base.

[0016] Through the above technical solution, the limiting plate can be easily installed on the top of the placement plate by the cooperation of the placement slot and the positioning column. Then, when the impact assembly is tested, the data can be easily understood by the cooperation of the sensor body and the display.

[0017] Preferably, a reinforcing plate is welded to one end of the support plate near the center line, and the reinforcing plate and the support plate form a "triangular" structure. A spring is fixedly installed on one end of the placement plate near the sliding column.

[0018] Through the above technical solution and the spring design, when testing is carried out, the sliding sleeve can come into contact with the spring, which can play a buffering role and prevent the sliding sleeve from directly impacting the top of the limiting plate, thus avoiding a short service life.

In addition, the design of the first extension ear and the second extension ear can play a guiding role, and can further improve its stability and impact accuracy during impact testing.

[0021] 2. This impact resistance testing device for implantable cardiac pacemakers, through the design of positioning groove and positioning sleeve, allows the positioning sleeve to be inserted into the positioning groove when the support plate is installed. With the installation frame, it can facilitate the quick installation of the support plate and also provide support for the placement plate, thereby improving its practicality. Through the spring design, when the test is performed, the sliding sleeve can contact the spring, which can play a buffering role and prevent the sliding sleeve from directly impacting the top of the limiting plate, thus avoiding a short service life.

[0032] 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.

[0033] Example 1: As Figure 1-9As shown in the figure, a shock resistance test device for an implantable cardiac pacemaker provided by the utility model includes a base 1. On the top of the base 1, a mounting frame 2 is fixedly installed. A limit seat 3 and a display member 4 are fixedly installed on one side of the mounting frame 2, and a sliding column 19 is fixedly installed at one end with the base 1 and at the other end with the mounting frame 2. Positioning plates 5 for positioning are fixedly installed on both sides of the mounting frame 2. On one side of the mounting frame 2 near the center point, there is a support plate 7 with a "U" - shaped cross - section for support. On the side of the support plate 7 close to the positioning plate 5, a fixing plate 9 and a cover plate 10 inserted with the positioning plate 5 are fixedly installed. On the top of the mounting frame 2, a shock component 21 slidably connected with the sliding column 19 is fixedly installed. On the top of the support plate 7 and at one end of the mounting frame 2 near the center line, there is a placement plate 14;

[0034] The shock component 21 includes a first cylinder 2101 on the top of the mounting frame 2. A first extension seat 2102 is fixedly installed on the output shaft of the first cylinder 2101. A second cylinder 2106 is fixedly installed at one end of the first extension seat 2102 close to the first cylinder 2101. A second extension seat 2107 is fixedly installed on the output shaft of the second cylinder 2106. A contact plate 2111 is arranged at one end of the second extension seat 2107 close to the base 1.

[0035] Specifically, first extension ears 2103 are fixedly installed on both sides of the first extension seat 2102. A sliding hole 2104 is formed through the top of the first extension ear 2103. The first extension seat 2102 is slidably connected with the sliding column 19 through the sliding hole 2104 on the first extension ear 2103. The advantage is that through the design of the first extension ear 2103, when the first cylinder 2101 adjusts its stroke, the first extension ear 2103 can slide at the sliding column 19, which can play a guiding role for it, avoid its displacement during the impact process, and improve the stability during the test.

[0036] Specifically, a limit frame 2105 with an "L" - shaped cross - section and abutting against the second cylinder 2106 is fixedly installed on one side of the first extension seat 2102 close to the first cylinder 2101. Second extension ears 2108 slidably connected with the sliding column 19 are fixedly installed on both sides of the second extension seat 2107. A sliding sleeve 2109 slidably connected with the sliding column 19 is fixedly installed at one end of the second extension ear 2108 close to the base 1. The advantage is that through the design of the second cylinder 2106 and the second extension ear 2108, when the second cylinder 2106 adjusts its stroke, through the cooperation of the sliding column 19, the sliding sleeve 2109 and the second extension ear 2108, it can play a guiding role for the second cylinder 2106, and can further improve its stability and the accuracy of displacement.

[0037] It should be noted that there may be some inaccuracies in the translation due to the complexity of the technical content. You can adjust it according to the actual situation. Also, the cross - section description of the support plate 7 as "几" - shaped in Chinese is not very clear. I translated it as "U" - shaped here for the sake of understanding, but you may need to confirm the actual shape with the original text.Specifically, the extension seat 2107 has a mounting groove 2110 on the side near the base 1. The extension seat 2107 has a contact plate 2111 through the mounting groove 2110. The advantage is that the contact plate 2111 can be installed on the impact assembly 21 through the cooperation of the mounting groove 2110 and the contact plate 2111. Then, when the first cylinder 2101 and the second cylinder 2106 push the contact plate 2111 to move, the contact plate 2111 can be impacted with the implantable pacemaker placed on the limiting plate 18.

[0038] Example 2: Figure 2-9 As shown, this is an improvement on the previous embodiment.

[0039] Specifically, a positioning groove 6 is provided at the end of the positioning plate 5 away from the base 1, and a positioning sleeve 11 that matches the positioning groove 6 is fixedly installed at the end of the cover plate 10 near the positioning plate 5. A positioning hole 12 is provided through the top of the cover plate 10, and a positioning bolt 13 is threaded between the positioning plate 5 and the cover plate 10. The advantage is that, through the design of the positioning groove 6 and the positioning sleeve 11, when the support plate 7 is installed, it can be inserted into the positioning groove 6 through the positioning sleeve 11. With the help of the mounting bracket 2, it can facilitate the quick installation of the support plate 7, and at the same time, it can also support the placement plate 14, which can improve its practicality.

[0040] Specifically, a placement slot 15 is provided through the side of the placement plate 14 near the mounting bracket 2. A positioning post 16 and a sensor body 17 electrically connected to the display 4 are inserted and installed on the inner surface of the placement slot 15. A limit plate 18 is provided on the side of the placement plate 14 away from the base 1. The advantage is that the limit plate 18 can be easily installed on the top of the placement plate 14 through the cooperation of the placement slot 15 and the positioning post 16. Then, when the impact assembly 21 is tested, its data can be easily obtained through the cooperation of the sensor body 17 and the display 4.

[0041] Specifically, a reinforcing plate 8 is welded to one end of the support plate 7 near the center line. The reinforcing plate 8 and the support plate 7 form a "triangular" structure. A spring 20 is fixedly installed on one end of the placement plate 14 near the sliding column 19. The advantage is that, through the design of the spring 20, when testing is carried out, the sliding sleeve 2109 can come into contact with the spring 20, which can play a buffering role and prevent the sliding sleeve 2109 from directly impacting the top of the limiting plate 18, thus avoiding a short service life.

[0042] Working Principle: During use, the design of the first extension ear 2103 allows the first cylinder 2101 to slide at the sliding post 19 when its stroke is adjusted, thus guiding it and preventing displacement during impact, improving stability during testing. The design of the second cylinder 2106 and the second extension ear 2108 allows the second cylinder 2106 to be guided by the sliding post 19 in conjunction with the sliding sleeve 2109 and the second extension ear 2108 when its stroke is adjusted, further improving stability and displacement accuracy. The mounting groove 2110 and the contact plate 2111 allow the contact plate 2111 to be mounted on the impact assembly 21. Subsequently, when the first cylinder 2101 and the second cylinder 2106 push the contact plate 2111 to move... This allows the contact plate 2111 to undergo impact testing with the implantable pacemaker placed on the limiting plate 18. Through the design of the positioning groove 6 and the positioning sleeve 11, when the support plate 7 is installed, the positioning sleeve 11 can be inserted into the positioning groove 6. Combined with the mounting bracket 2, this facilitates the quick installation of the support plate 7 and also provides support for the placement plate 14, improving its practicality. Through the cooperation of the placement groove 15 and the positioning post 16, the limiting plate 18 can be easily installed on top of the placement plate 14. Subsequently, when the impact assembly 21 is tested, the sensor body 17 and the display 4 can be used to easily understand its data. Through the design of the spring 20, when testing, the sliding sleeve 2109 can contact the spring 20, providing a buffering effect and preventing the sliding sleeve 2109 from directly impacting the top of the limiting plate 18, thus avoiding a shorter service life.

[0043] 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.
