Embodiment 1

[0057] Please refer to Figure 1 to Figure 3 , figure 1 It is a perspective view of the use state of the fixation device for in vitro testing of the pacemaker in Embodiment 1 of the present invention, figure 2 It is the front view of the fixture device for in vitro testing of the pacemaker according to Embodiment 1 of the present invention, image 3 yes figure 2 Top view of the fixture shown.

[0058] Such as Figure 1 to Figure 3 As shown, the present embodiment provides a fixing device for in vitro testing of pacemakers, the fixing device includes a base 30 and a first fixing part 10 disposed on the base 30, and the first fixing part 10 defines an accommodation space 100 , which can be used to accommodate a pacemaker 40, and the first fixing part 10 can be locked with the pacemaker 40, that is, the first fixing part 10 can limit the direction and position of the pacemaker 40 . When testing the pacemaker 40, the pacemaker 40 is locked on the fixing device, and the ele...

Embodiment 2

[0099] Please refer to Figure 8 and Figure 9 , Figure 8 It is the front view of the fixture device for in vitro testing of the pacemaker according to the second embodiment of the present invention, Figure 9 yes Figure 8 Top view of the fixture shown.

[0100] The difference from the first embodiment is that the first fixing part 11 of this embodiment only has the fixing body 111 without the supporting body 124 , and only the third side wall 123 has a porous structure. Preferably, any two of the first side wall 121 , the second side wall 122 and the third side wall 123 are arranged on the same side and are perpendicular to each other.

[0101] Here, because the first fixing part 11 does not have a support body 124, the accommodating space 100 of the first limiting part 12 has a higher degree of opening than that of the first embodiment. When any side wall of a limiting part 12 is attached, most of the simulated fluid in vitro can be discharged through the open area of...

Embodiment 3

[0106] Please refer to Figure 10 and Figure 11 , Figure 10 is the front view of the fixture device for in vitro testing of the pacemaker according to Embodiment 3 of the present invention, Figure 11 yes Figure 10 Top view of the fixture shown.

[0107] The difference from the first embodiment is that the first fixing part 11 of this embodiment only has the fixing body 111 without the supporting body 124 , and only the second side wall 122 and the third side wall 123 are porous structures. Preferably, any two of the first side wall 121 , the second side wall 122 and the third side wall 123 are arranged on the same side and are perpendicular to each other.

[0108] In addition, in this embodiment, the fixing body 111 is preferably disposed parallel to the third side wall 123 , and is perpendicular to and connected to the first side wall 121 and the second side wall 122 respectively. The locking body 112 is preferably an elastic piece, one end of which is connected to t...

Abstract

The invention provides a fixing device, a testing device and a testing method for in vitro testing of a pacemaker. Specifically, the fixing device can conveniently fix the position of the pacemaker in an in vitro simulated fluid, and solve the problem of pacing and sensing in the test of a pacemaker. The adverse effect on the pacemaker test due to changes in the direction and position of the pacemaker during functioning. Specifically, the bipolar pacing and sensing test of the pacemaker can be realized through the first fixing part of the fixing device, and the unipolar pacing of the pacemaker can also be realized through the first fixing part and the second fixing part of the fixing device And sensing test, especially when testing the unipolar pacing and sensing function of the pacemaker, the relative position of the pacemaker and the electrode lead can be fixed to avoid the impedance change between the pacemaker and the electrode lead, thereby avoiding the pacemaker The adverse effect caused by the position change of the electrode wire and the electrode wire on the test is improved, and the accuracy of the test is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a fixture, a testing device and a testing method for in vitro testing of a pacemaker. Background technique [0002] Cardiac pacemaker is an electronic therapy device implanted in the body. It sends out electric pulses powered by batteries through the pulse generator, conducts through the electrode wires, and then stimulates the myocardium in contact with the electrodes to excite and contract the heart, thereby achieving The purpose of treating the disease of bradycardia. At the same time, the pacemaker also senses the electrical signal of the heart through the wire, so as to judge whether it needs to provide energy to send out the electric pulse. [0003] Before the pacemaker is implanted in the body, the pacemaker is generally placed at a predetermined position in the simulated fluid outside the body, so as to test the pacing and sensing functions of the pacemaker in th...
