Description

Technical Field

[0001] The present invention relates to the technical field of cardiac pacemakers, in particular to a switching structure for switching a permanent pacemaker to a temporary pacemaker. Background Art

[0002] Temporary pacemakers are used for patients who need cardiac pacing temporarily. However, because the electrodes of temporary pacemakers are not screwed onto the heart, they may be dislocated due to patient activities, affecting the pacing effect and the patient's life safety. The electrodes of permanent pacemakers can be screwed onto the heart, are not easily dislocated, and do not affect the patient's activities, but need to be used in conjunction with permanent pacemakers.

[0003] In clinical use, in many cases, it is not necessary to use a permanent pacemaker for a long time. In many cases, a temporary pacemaker is used for temporary pacing operations. However, due to the problem that the temporary pacemaker electrodes are easily dislocated, there are defects in use. If the temporary pacemaker is used in conjunction with the electrodes of the permanent pacemaker that can be screwed onto the heart, then the defect of the temporary pacemaker electrodes being not firmly fixed can be compensated.

[0004] However, the current permanent pacemaker electrode wire has a column-type plug, while the temporary pacemaker electrode wire has a pin-type plug, and the two models are not interchangeable. Therefore, in clinical use, the permanent pacemaker electrode wire cannot be connected to the temporary pacemaker for temporary use, and its use is limited. Summary of the invention

[0043] 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.

[0044] The present invention provides two technical solutions:

[0045] Figure 1-Figure 5 The first embodiment is shown: a switching structure of a permanent pacemaker to a temporary pacemaker, comprising a housing 1, and further comprising:

[0046] The adapter 2 is inserted into the housing 1, one end of the adapter 2 is provided with two sockets 21 for plugging the columnar plug of the permanent pacemaker, and the other end of the adapter 2 is connected to two pin plugs 22 connected to the temporary pacemaker through a wire 23;

[0047] A fastener 3, disposed on the top of the housing 1, for manually fastening two cylindrical plugs of the permanent pacemaker at the same time;

[0048] The flip cover 4 is rotatably arranged at a bottom corner of the outer shell 1 by means of a hinge, and the flip cover 4 forms a complete shell when closed with the outer shell 1, and the fastener 3 fastens the two columnar plugs while fastening the flip cover 4 synchronously; a vertical rib 42 is arranged on the inner wall of the flip cover 4 near the rotating end, so that after the flip cover 4 is closed with the outer shell 1, the vertical rib 42 abuts against one end of the adapter 2 to limit the movement of the adapter 2, so that the adapter 2 does not need an additional fixing structure; the flip cover 4 is designed to be openable, which is convenient for inserting and removing the fastener 3, and is also convenient for winding or releasing the wire 23 after opening, and is also convenient for fixing the gear cover 36 with screws from the inside.

[0049] A wire fixing structure 5, arranged on one side of the top of the housing 1, for fixing the wire harness of the permanent pacemaker columnar plug;

[0050] The pin plug 22 can be snap-fitted and fixed between the housing 1 and one end of the flip cover 4. A ring groove 25 is provided on the surface of the pin plug 22. A round hole 12 for snapping into the ring groove 25 is correspondingly provided at one end of the housing 1 and the flip cover 4. Alternatively, the pin plug 22 can be detached from the housing 1 and the flip cover 4 and extended for use through a wire 23. A winding tube 13 sleeved on the outside of a long fastening screw 31 is provided at the bottom of the inner surface of the housing 1. The winding tube 13 is used to wind the wire 23.

[0051] In this embodiment, the fastener 3 includes:

[0052] A long fastening screw 31 passes through one side of the top of the housing 1, and a first nut 41 corresponding to the position of the long fastening screw 31 is fixed inside the flip cover 4. The flip cover 4 is fixed after the long fastening screw 31 and the first nut 41 are tightened;

[0053] Two short fastening screws 32 pass through the middle of the top of the shell 1. A second nut 24 adapted to the two short fastening screws 32 is fixed on one side of the top of the adapter 2. A fastening hole vertically connected to the socket 21 is opened inside the second nut 24 at the top of the adapter 2, so that the short fastening screws 32 are screwed into the inner thread of the second nut 24 to tighten the permanent pacemaker columnar plug.

[0054] A small gear 33 is fixed to the top of the long fastening screw 31 and the two short fastening screws 32, and a large gear 34 is meshed between the three small gears 33. A screw cap 35 is inserted in the center of the large gear 34. A gear cover 36 for covering the large gear 34 and the small gear 33 is provided on the top of the housing 1, and the central axis of the screw cap 35 passes through the gear cover 36. Elastic members 38 are provided on the tops of the large gear 34 and the small gear 33 to elastically press down the large gear 34 and the small gear 33. The elastic member 38 is a spring. The downward pressure of the spring can promote the long fastening screw 31 and the two short fastening screws 32 to be smoothly screwed into the nut.

[0056] In order to fix the adapter structure on the body surface, a flexible silicone sleeve 7 is fixed to the bottom of the flip cover 4 and the shell 1, and the top of the flexible silicone sleeve 7 is lower than the hinge to avoid the hinge rubbing the skin when it is attached to the skin surface; a medical tape 6 can be inserted inside the flexible silicone sleeve 7 to stick the adapter structure to the body surface.

[0057] By setting up an adapter 2, one end of which can be inserted into the columnar plug of the permanent pacemaker, and the pin plug 22 at the other end can be inserted into the connector of the temporary pacemaker, thereby connecting the electrode wire of the permanent pacemaker to the temporary pacemaker to meet temporary use, so that the electrode of the temporary pacemaker can also be firmly fixed to the heart; and the fastener 3 set on the device can conveniently fix the columnar plug with sight, and there is no need to tighten the screw with a screwdriver like in the prior art. It only needs to manually turn the screw cap 35, which is convenient for temporary manual operation, and two columnar plugs can be tightened at the same time, which also improves efficiency.

[0058] Figure 6-Figure 7 A second embodiment is shown, which is mainly different from the first embodiment in that the wire fixing structure 5 comprises:

[0059] The bottom plate 51 is fixed to the top of the housing 1, and a lower rubber pad 57 is pasted on the top of the bottom plate 51; a gap for the gear cover 36 to slide needs to be reserved between the bottom plate 51 and the buckle 11;

[0060] Two sets of elastic arched pressing pieces 52, one end of which rotates with the top of the bottom plate 51 through the rotating shaft 53, and the other end of the elastic arched pressing piece 52 is bent and set to a sleeve-type structure 521;

[0061] The fixing rod 54 passes through the sleeve-type structure 521 of the two sets of elastic arched pressing pieces 52, and the fixing rod 54 can slide in the sleeve-type structure 521 along the length direction of the elastic arched pressing piece 52, and a space is reserved for the fixing rod 54 to slide, so that it can pass over the ferrule 55 and cover the ferrule 55. The two ends of the fixing rod 54 are thickened, and the inner arc surface of the elastic arched pressing piece 52 is pasted with a rubber pad 56;

[0062] The clamping sleeve 55 is used to clamp the fixing rod 54 to limit the flipping and opening of the elastic arched pressing piece 52; the top part of the clamping sleeve 55 is tilted so that when the elastic arched pressing piece 52 bounces up the fixing rod 54, it will prompt the fixing rod 54 to slide toward the corner of the clamping sleeve 55, thereby preventing the fixing rod 54 from detaching from the clamping sleeve 55. The fixing rod 54 can be detached from the clamping sleeve 55 only by manually pressing and pushing it.

[0063] By designing a wire fixing structure 5 on the top of the adapter structure, the electrode wire can be fixed by a simple pressing operation to prevent it from moving randomly and being pulled, thereby positioning the electrode wire. The fixing and releasing operations are simple and convenient, and the axial sliding of the electrode wire can also be avoided by using the rubber pad.
