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 for in-vitro test of a pacemaker, a test device, and a test method, which can conveniently fix the position of the pacemaker in in-vitro simulation liquid through the fixing device and can solve the adverse influence on the test of the pacemaker due to change of the direction and the position of the pacemaker during the test of pace-making and perception functions of the pacemaker. Specifically, bipolar pace-making and perception test of the pacemaker can be realized through a first fixing portion of the fixing device, unipolar pace-making and perceptiontest of the pacemaker can also be realized through the first fixing portion and a second fixing portion of the fixing device, the relative positions of the pacemaker and an electrode wire can be fixedespecially during the test of unipolar pace-making and perception functions of the pacemaker, the impedance change between the pacemaker and the electrode wire can be avoided, the adverse influence caused by the position change of the pacemaker and the electrode wire on the test is avoided, and the test accuracy 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...
