Description

Technical Field

[0001] This utility model belongs to the field of temporary pacemaker technology, and in particular relates to a fixation component for a temporary pacemaker. Background Technology

[0002] A temporary pacemaker is a cardiac pacing device used for short-term purposes, primarily to maintain a patient's heart rate in emergency situations or to provide cardiac rhythm support during cardiac surgery or medication adjustments. Temporary pacemakers are commonly used for patients requiring temporary heart rate management due to acute bradycardia, cardiac conduction block, or other electrical activity abnormalities.

[0003] There are many types of temporary pacemakers on the market. For example, a temporary cardiac pacemaker is disclosed on the China Patent Network with the publication number CN210963571U. This temporary cardiac pacemaker has a simple structure and is more convenient for temporary cardiac pacing. However, there are some defects and shortcomings that need to be improved: (1) Some existing temporary pacemakers are non-implantable devices with related components located outside the body. They can be used by hanging them on the bedside or clothing through hooks or other structures. However, the hook structure is often fixed to the temporary pacemaker device and is difficult to disassemble. When the hook is deformed or even broken due to long-term stress, it cannot be replaced separately; (2) Some existing temporary pacemakers require connecting wires when in use, but there is a lack of effective fixation for the wires. This makes it easy for the wires to twist or become tangled after being connected to the temporary pacemaker, thus affecting the normal use of the temporary pacemaker; (3) Some existing temporary pacemakers are prone to loosening after the wires are inserted into the interface. When the patient moves slightly, the wires will be pulled, causing the connector to fall off from the interface. Therefore, the temporary pacemaker fixation component provided by this utility model is of great significance in addressing the above problems. Utility Model Content

[0004] This invention provides a fixing component for a temporary pacemaker. A hook allows the housing and pacemaker body to be suspended together on a bedside rail or clothing for use. When the hook deforms or breaks due to prolonged stress, the housing can be slid off the pacemaker body 5 for replacement. By squeezing the lead wire, it can be inserted into the wire-fixing groove until it fits into the wire-fixing hole. The wire-fixing hole effectively fixes the lead wire, preventing twisting or tangling after connection to the pacemaker body, which would affect the normal use of the temporary pacemaker. The magnetic force generated by the magnet attracts the magnetic block, firmly fixing the connector within the interface. This effectively prevents the connector from detaching from the interface due to pulling on the lead wire during slight patient movement. In summary, this invention solves the problems in the prior art.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model discloses a temporary pacemaker fixing component, comprising a housing with a C-shaped side and a hook fixedly connected to its back. Several blocks are fixedly connected to the top and bottom inner walls of the housing. Several docking holes are provided on the top of the housing. A pacemaker body is disposed inside the housing, and a display screen and buttons are respectively installed on the pacemaker body. Several interfaces are provided on the top of the pacemaker body, and connectors that mate with the interfaces are inserted into the interfaces. Wires are electrically connected to the connectors, and the other end of the wires is electrically connected to electrode pads. Wire holders are installed on both sides of the pacemaker body. The wire holders are C-shaped, with wire-fixing holes on the top and bottom, and wire-fixing grooves are formed between the wire-fixing holes and the side walls of the wire holders.

[0007] Furthermore, the hook is 7-shaped, and its inner wall surface is provided with a layer of anti-slip pad, the surface of which is engraved with herringbone anti-slip patterns.

[0008] Furthermore, the distance between the stop block and the front end face of the housing is equal to the thickness of the pacemaker body. The wire support frame is provided with positioning holes. Fixed shafts are fixedly connected to both sides of the pacemaker body. The diameter of the fixed shaft is equal to the diameter of the positioning hole. The end of the fixed shaft passes through the positioning hole and is fixedly connected to a protrusion. The protrusion is attached to the side wall of the wire support frame.

[0009] Furthermore, the wire-fixing hole is circular, and its diameter is equal to the diameter of the wire; the wire-fixing groove is rectangular, and its width is smaller than the diameter of the wire-fixing hole.

[0010] Furthermore, the number of the mating holes is the same as the number of interfaces, the diameter of the holes is equal to the diameter of the wires, and the center of each mating hole is on the same straight line as the center of each interface.

[0011] Furthermore, magnets are provided on both sides of each of the mating holes. The magnets are fixedly connected to the top of the housing and are symmetrically distributed about the mating holes. A magnetic block is fixedly connected to one end of the wire near the connector.

[0012] Furthermore, a sleeve is fitted onto one end of the wire near the electrode plate. Several adhesive tapes are fixedly connected to the outer walls of both sides of the sleeve. The adhesive tapes are long strips and are distributed linearly at equal intervals along the length of the sleeve. A layer of release paper is pasted on both the front and back of the adhesive tapes.

[0013] The present invention has the following advantages over the prior art:

[0014] (1) When using a temporary pacemaker fixing component of this utility model, the housing and pacemaker body can be hung together on the bedside railing or clothing by means of a hook. When the hook is deformed or even broken due to long-term stress, the housing can be removed from the pacemaker body 5 by sliding so that the housing and hook can be replaced.

[0015] (2) When using a temporary pacemaker fixing component of the present invention, the wire can be squeezed into the fixing groove until the wire is attached to the fixing hole. The wire can be effectively fixed through the fixing hole to prevent it from twisting or tangling after being connected to the pacemaker body, which would affect the normal use of the temporary pacemaker.

[0016] (3) When using a temporary pacemaker fixing component of this utility model, the magnetic force generated by the magnet can attract the magnetic block so as to firmly fix the connector in the interface, thereby effectively preventing the lead wire from being pulled when the patient moves slightly, causing the connector to fall off from the interface.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0029] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] In the description of this utility model, it should be understood that the terms "relative", "one end", "inner", "lateral", "end", "both ends", "both sides", "front", "one end face", "the other end face", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0031] Please see Figure 1-8As shown, a temporary pacemaker fixing component of this utility model includes a housing 1. The side of the housing 1 is C-shaped, and a hook 2 is fixedly connected to its back. Several blocks 3 are fixedly connected to the top and bottom inner walls of the housing 1. Several docking holes 4 are opened on the top of the housing 1, and a pacemaker body 5 is arranged inside the housing 1. The pacemaker body 5 is equipped with a display screen 6 and buttons 7. Parameters such as heart rate, pulse amplitude, and pacing mode can be set through the buttons 7. The pacemaker body 5 has a built-in battery to power it, ensuring continuous operation of the device in emergency situations. Several interfaces 8 are opened on the top of the pacemaker body 5, and the interfaces 8 are inserted into... The device has a connector 9 that mates with it. A wire 10 is electrically connected to the connector 9. The other end of the wire 10 is electrically connected to an electrode pad 11. The electrode pad 11 is attached to the patient's chest and is used to transmit pulses. When the connector 9 is inserted into the interface 8, the electrode pad 11 and the pacemaker body 5 can be electrically connected through the wire 10 so that the electrical pulse can be transmitted to the myocardium. The electrode pad 11 can then emit electrical stimulation pulses to trigger the contraction of the heart muscle to maintain heart rate and blood circulation. Both sides of the pacemaker body 5 are equipped with a wire holder 12. The wire holder 12 is C-shaped and has wire holes 13 at its top and bottom. A wire groove 14 is formed between the wire hole 13 and the side wall of the wire holder 12.

[0032] The hook 2 is shaped like the number 7, and its inner wall surface is provided with a layer of anti-slip pad 15. The surface of the anti-slip pad 15 is engraved with herringbone anti-slip texture. The hook 2 is made of soft plastic material, which is elastic and can be slightly deformed when subjected to external force. The shell 1 and the pacemaker body 5 can be hung together on the bed rail or clothing through the hook 2 for use. The anti-slip texture on the surface of the anti-slip pad 15 can increase the friction between the hook 2 and the bed rail or clothing, so as to play an anti-slip role and prevent the pacemaker body 5 from slipping and shifting when suspended.

[0033] The distance between the stop block 3 and the front end face of the housing 1 is equal to the thickness of the pacemaker body 5. The pacemaker body 5 can be inserted and fitted between the stop block 3 and the front end face of the housing 1 to fix the housing 1 on the rear side of the pacemaker body 5. When the hook 2 is deformed or even broken due to long-term stress, the housing 1 can be removed from the pacemaker body 5 by sliding so that the housing 1 and the hook 2 can be replaced. The cable holder 12 is provided with a positioning hole 16. The two sides of the pacemaker body 5 are fixedly connected to the fixing shaft 17. The diameter of the fixing shaft 17 is equal to the diameter of the positioning hole 16. The end of the fixing shaft 17 passes through the positioning hole 16 and is fixedly connected to the protrusion 18. The protrusion 18 fits against the side wall of the cable holder 12. The cable holder 12 can be fixed by the mutual cooperation between the fixing shaft 17 and the protrusion 18. The cable holder 12 can rotate around the fixing shaft 17 so that the angle of the cable holder 12 can be adjusted as needed.

[0034] The wire fixing hole 13 is circular, and its diameter is equal to that of the wire 10. The wire fixing groove 14 is rectangular, and its width is smaller than that of the wire fixing hole 13. The wire fixing frame 12 is made of soft plastic, which is elastic and will deform slightly when subjected to external force. By squeezing the wire 10, it can be inserted into the wire fixing groove 14 until the wire 10 fits in the wire fixing hole 13. At this time, the wire fixing hole 13 can effectively fix the wire 10 to prevent it from twisting or tangling after being connected to the pacemaker body 5, which would affect the normal use of the temporary pacemaker.

[0035] The number of mating holes 4 is the same as that of interfaces 8, and their diameter is equal to that of wires 10. The center of each mating hole 4 is on the same straight line as the center of each interface 8. When the connector 9 is inserted into the interface 8, the wires 10 can be inserted into the mating holes 4 and fit against the inner wall of the mating holes 4 to play a role in limiting and guiding.

[0036] Each docking hole 4 has a magnet 19 on both sides. The magnets 19 are fixedly connected to the top of the housing 1 and are symmetrically distributed about the docking hole 4. A magnetic block 20 is fixedly connected to one end of the wire 10 near the connector 9. The magnetic block 20 is made of metal. When the connector 9 is inserted into the interface 8, the magnetic block 20 can come into contact with the magnet 19. At this time, the magnetic force generated by the magnet 19 can attract the magnetic block 20, so as to firmly fix the connector 9 in the interface 8. This can effectively prevent the wire 10 from being pulled when the patient moves slightly, causing the connector 9 to fall off from the interface 8.

[0037] The lead wire 10 is fitted with a sleeve 21 at one end near the electrode pad 11. Several adhesive tapes 22 are fixedly connected to the outer walls of both sides of the sleeve 21. The adhesive tapes 22 are long strips and are distributed linearly at equal intervals along the length of the sleeve 21. A layer of release paper 23 is pasted on both the front and back of the adhesive tapes 22. When the electrode pad 11 is pasted on the patient's chest, the release paper 23 on the adhesive tapes 22 can be peeled off, and the adhesive tapes 22 can be pasted on the skin around the patient's chest. At this time, the sleeve 21, the lead wire 10 and the electrode pad 11 can be fixed together by the multiple adhesive tapes 22 to prevent the position of the electrode pad 11 from shifting. The sleeve 21 can drive the adhesive tapes 22 to slide up and down along the lead wire 10 so as to adjust the position of the adhesive tapes 22 as needed.

[0038] The circuits, electronic components, and chip modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0039] All standard parts used in the application documents can be purchased from the market. All components in this application document can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The electrical components mentioned in this document are all connected to the external main controller and 220V mains power. The main controller is a conventional known device that can play a control role.

[0040] The working principle of this utility model is as follows:

[0041] In use, the pacemaker body 5 can be inserted and fitted between the stop block 3 and the front end face of the housing 1, so that the housing 1 can be fixedly installed on the rear side of the pacemaker body 5. The housing 1 and the pacemaker body 5 can be hung together on the bedside rail or clothing by the hook 2. The pacemaker body 5 is equipped with a display screen 6 and a button 7. The heart rate, pulse amplitude, pacing mode and other parameters can be set by the button 7. The pacemaker body 5 has a built-in battery to power the pacemaker body 5, so that the device can continue to operate in an emergency. The electrode pads 11 are attached to the patient's chest to transmit pulses. When the connector 9 is inserted into the interface 8, the electrode pads 11 and the pacemaker body 5 can be electrically connected by the wire 10 so that the electrical pulses can be transmitted to the myocardium. The electrode pads 11 can then emit electrical stimulation pulses to trigger the contraction of the heart muscle to maintain heart rate and blood circulation. By squeezing the wire 10, it can be inserted into the wire fixing groove 14 until the wire 10 is attached to the wire fixing hole 13. The lead wire 10 can be effectively fixed through the fixing hole 13 to prevent it from twisting or tangling after being connected to the pacemaker body 5, which would affect the normal use of the temporary pacemaker. When the connector 9 is inserted into the interface 8, the magnetic block 20 can contact the magnet 19. At this time, the magnetic force generated by the magnet 19 can attract the magnetic block 20 to firmly fix the connector 9 in the interface 8, thereby effectively preventing the lead wire 10 from being pulled and causing the connector 9 to fall off from the interface 8 when the patient moves slightly. When the electrode pad 11 is pasted on the patient's chest, the release paper 23 on the tape 22 can be peeled off and the tape 22 can be pasted on the skin around the patient's chest. At this time, the cannula 21, together with the lead wire 10 and the electrode pad 11, can be fixed together by multiple tapes 22 to prevent the position of the electrode pad 11 from shifting. When the hook 2 is deformed or even broken due to long-term stress, the shell 1 can be removed from the pacemaker body 5 by sliding to replace the shell 1 and the hook 2.
