Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, specifically to an electric cardiopulmonary resuscitation machine with lifting, folding and quick locking functions. Background Technology

[0002] Cardiopulmonary resuscitation (CPR) machines, also known as cardiopulmonary resuscitation devices, are mechanical devices that replace human labor in performing basic life support operations such as artificial respiration and chest compressions. There are two main types: electric CPR machines and pneumatic CPR machines. These devices can provide high-quality, uninterrupted artificial circulation and ventilation support. Some portable CPR devices can also be used in hospital emergency rooms and will not affect their normal operation even when patients are transferred.

[0003] In emergency situations, cardiopulmonary resuscitation (CPR) machines are crucial emergency equipment, and their installation and portability significantly impact the effectiveness of resuscitation. However, traditional CPR machines are typically large, complex to operate, and difficult to combine quickly, severely affecting the timeliness and effectiveness of resuscitation. Utility Model Content

[0004] One of the technical problems this application aims to solve is that traditional cardiopulmonary resuscitation (CPR) machines are usually large in size, complex to operate, and difficult to combine quickly, which seriously affects the timeliness and effectiveness of rescue.

[0005] To address the aforementioned technical problems, this application provides an electric cardiopulmonary resuscitation (CPR) machine with a lifting, folding, and quick-locking function, comprising a CPR machine body, a control panel for controlling the CPR machine body, and further including:

[0006] Two folding arms are symmetrically arranged on both sides of the cardiopulmonary resuscitation machine body, and one end of each folding arm is rotatably connected to the outer wall of the cardiopulmonary resuscitation machine body.

[0007] Two lifting arms are fixedly installed on the two folding arms at the ends away from the main body of the cardiopulmonary resuscitation machine. The lifting arms are equipped with lifting buttons for controlling the extension and retraction of the lifting arms.

[0008] An annular groove is formed on the end of the lifting arm away from the folding arm;

[0009] The back plate structure has through holes at both ends that align with the bottom end of the lifting arm. A locking box is fixedly connected to the back plate structure below the through holes. A locking device is embedded in the inner cavity of the locking box, and an unlocking device is also installed on the outer wall of the locking box.

[0010] Preferably, the two folding arms are staggered when in the folded state, and each of the two folding arms is equipped with a folding button at the connection point between it and the main body of the cardiopulmonary resuscitation machine.

[0011] Preferably, the locking box is fixedly installed at the bottom of both ends of the back plate structure, and a limiting hole is provided on the top wall of the locking box, the diameter of which is equal to the diameter of the telescopic section of the lifting arm.

[0012] Preferably, the locking device consists of two limiting slide plates embedded in the locking box and capable of sliding within the locking box. Each of the two limiting slide plates is slidably connected to a locking slide plate. One adjacent end of each of the two locking slide plates has a semi-circular notch adapted to the annular groove, and the notch has a sloping step. A spring is provided between the two ends of the two locking slide plates and the inner wall of the locking box, and the two ends of the spring are fixedly connected to the ends of the locking slide plates and the inner wall of the locking box, respectively.

[0013] Preferably, bearings are rotatably connected to the outer walls of both locking slides, and inclined surfaces corresponding to the bearings are provided on the side walls of the limiting slides. The unlocking device is an unlocking button that slides on the side wall of the locking box, and one end of the unlocking button is fixed to the limiting slide inside the locking box.

[0014] Preferably, the back panel structure is a bed back panel located below the main body of the cardiopulmonary resuscitation machine, and the bed back panel has multiple fixing holes symmetrically opened at both ends.

[0015] Preferably, the backplate structure is an external backplate located below the main body of the cardiopulmonary resuscitation machine. Both ends of the external backplate are fixedly connected to pads, and through holes are also provided on the external backplate above the pads.

[0016] This utility model has at least the following beneficial effects:

[0017] 1. The bed back panel is fixed to the stretcher through fixing holes. When a patient needs to be resuscitated before the hospital, the folding arm can be unfolded and fixed. Then, the bottom end of the lifting arm is inserted into the locking box after passing through the bed back panel. The locking plate in the locking box, together with the annular groove at the bottom end of the lifting arm, fixes the main body of the cardiopulmonary resuscitation machine above the lifting arm. The cardiopulmonary resuscitation machine can then be started to resuscitate the patient. The installation and operation are convenient and quick, which greatly improves the efficiency of emergency treatment and the success rate of treatment.

[0018] 2. When going out to rescue patients, the lifting arm can be folded by rotating the folding arm. At the same time, the lightweight outer back panel is used to make it convenient for medical staff to carry. After inserting the bottom end of the lifting arm through the outer back panel into the locking box, the locking slide is used in conjunction with the annular groove opened at the bottom end of the lifting arm to fix the main body of the cardiopulmonary resuscitation machine above the lifting arm, so that the patient can be rescued.

[0027] 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.

[0028] Example 1

[0029] Please see Figure 1-6 This utility model provides a technical solution:

[0030] An electric cardiopulmonary resuscitation (CPR) machine with lifting, folding, and quick-locking functions includes a CPR machine body 1, a control panel 2 for controlling the CPR machine body 1, and further includes:

[0031] Two folding arms 3 are symmetrically arranged on both sides of the cardiopulmonary resuscitation machine body 1. One end of the folding arm 3 is rotatably connected to the outer wall of the cardiopulmonary resuscitation machine body 1, so that the user can fold the folding arm 3 when not in use, reducing the space occupied by the overall structure and making it convenient for medical staff to carry when going out.

[0032] Two lifting arms 5 are respectively fixedly installed at the ends of the two folding arms 3 away from the main body 1 of the cardiopulmonary resuscitation machine. Each lifting arm 5 is equipped with a lifting button 6 for controlling the extension and retraction of the lifting arm 5. The lifting arm 5 is raised and lowered by controlling the lifting button 6, adjusting the distance between the bottom of the main body 1 of the cardiopulmonary resuscitation machine and the patient's chest. The machine also includes:

[0033] An annular groove 7 is provided on the end of the lifting arm 5 away from the folding arm 3;

[0034] The backplate structure has through holes 9 at both ends that align with the bottom end of the lifting arm 5. A locking box 11 is fixedly connected to the backplate structure below the through holes 9. A locking device is embedded in the inner cavity of the locking box 11. The locking device is used to fix the bottom end of the lifting arm 5 in conjunction with the annular groove 7. An unlocking device is also installed on the outer wall of the locking box 11. The structure also includes:

[0035] The two folding arms 3 are staggered when they are folded to avoid interference between them during the folding process. Folding buttons 4 are installed at the connection points between the two folding arms 3 and the main body 1 of the cardiopulmonary resuscitation machine, so that the user can fix the unfolded or folded folding arms 3 by using the folding buttons 4.

[0036] The locking box 11 is fixedly installed at the bottom of both ends of the back plate structure. The top wall of the locking box 11 has a limit hole 12, the diameter of which is equal to the diameter of the telescopic section of the lifting arm 5.

[0037] The locking device consists of two limiting slide plates 21 embedded within the locking box 11 and capable of sliding within it. Locking slide plates 13 are slidably connected to each of the two limiting slide plates 21. Each locking slide plate 13 has a semi-circular notch at one adjacent end that matches the annular groove 7, and the notch has a sloping step. A spring 15 is provided between the two ends of the locking slide plates 13 and the inner wall of the locking box 11. The two ends of the spring 15 are fixedly connected to the ends of the locking slide plates 13 and the inner wall of the locking box 11, respectively. The device also includes:

[0038] Bearings 14 are rotatably connected to the outer walls of both locking slide plates 13. An inclined surface 16 corresponding to the bearing 14 is provided on the side wall of the limiting slide plate 21. The unlocking device is an unlocking button 17 slidably connected to the side wall of the locking box 11. One end of the unlocking button 17 is fixed to the limiting slide plate 21 inside the locking box 11. A slot 22 is provided on the side wall of the limiting slide plate 21. Two detection sliders 23 are symmetrically installed inside the locking box 11 above the limiting slide plate 21. The ends of the two detection sliders 23 that are far apart are fixedly connected to the inner wall of the locking box 11 by return springs. A locking post 24, which is slidably connected to the detection slider 23, is embedded in the end of each detection slider 23 near the slot 22. An elastic reset member 25 is fixedly connected to the end of the locking post 24 inside the detection slider 23. The extension length of the elastic reset member 25 is less than the sliding length of the detection slider 23. When the unlock button 17 is pressed into the locking box 11, the limit slide plate 21 will be pushed to slide into the locking box 11 in sync. When the slot 22 slides to be aligned with the pin 24, the pin 24 is inserted into the slot 22 under the squeezing action of the elastic reset member 25, locking the unlock button 17 and preventing the unlock button 17 from rebounding. When the bottom end of the lifting arm 5 is pulled out of the locking box 11, the detection slider 23 loses its blocking effect and slides towards the center of the locking box 11 under the push of the reset spring, driving the pin 24 to move and disengage the pin 24 from the slot 22. At this time, the unlock button 17 can be released and reset, avoiding the need to press the unlock button 17 at the same time to pull out the lifting arm 5.

[0039] The back panel structure is a bed back panel 8 located below the main body 1 of the cardiopulmonary resuscitation machine. Multiple fixing holes 10 are symmetrically opened at both ends of the bed back panel 8.

[0040] The bed backrest 8 is fixed to the stretcher through the fixing holes 10. When the patient needs cardiopulmonary resuscitation before the hospital, after the patient is laid flat on the bed backrest 8, the two folding arms 3 are manually rotated outward to unfold them and fixed by the folding button 4. Then, the lifting arm 5 is extended to its longest position by the lifting button 6. The bottom end of the lifting arm 5 can then penetrate the bed backrest 8 and be inserted into the locking box 11 through the limiting hole 12. Because the bottom end of the lifting arm 5 is hemispherical, the lifting arm 5 will squeeze the two locking slide plates 13 to slide in opposite directions when inserted into the locking box 11 until the annular groove 7 at the bottom end of the lifting arm 5 is aligned with the notch on the locking slide plate 13. At this time, the two locking slide plates 13 are pushed by the elastic force of the spring 15. Insert the lifting arm 5 into the annular groove 7 from both sides to lock the bottom end. Medical staff can then adjust the main body 1 of the cardiopulmonary resuscitation machine to a suitable height again using the lifting button 6, and start the main body 1 of the cardiopulmonary resuscitation machine to rescue the patient. After the rescue is completed, push the unlocking button 17 into the locking box 11. Use the unlocking button 17 to squeeze the limiting slide plate 21 to move. The inclined surface 16 on the limiting slide plate 21 pushes the bearing 14 to move to both sides, so that the two locking slide plates 13 slide in opposite directions until the ends of the locking slide plates 13 are disengaged from the annular groove 7. Then, pull out the lifting arm 5 inserted into the locking box 11 from above to complete the disassembly. The operation is convenient and quick, which greatly improves the efficiency of emergency treatment and the success rate of treatment.

[0041] Example 2

[0042] Please see Figure 7 This utility model provides a technical solution:

[0043] Unlike Embodiment 1, this solution provides another implementation of an electric cardiopulmonary resuscitation machine with lifting, folding, and quick-locking functions:

[0044] An electric cardiopulmonary resuscitation (CPR) machine with lifting, folding, and quick-locking functions includes a CPR machine body 1, a control panel 2 for controlling the CPR machine body 1, and further includes:

[0045] Two folding arms 3 are symmetrically arranged on both sides of the cardiopulmonary resuscitation machine body 1. One end of the folding arm 3 is rotatably connected to the outer wall of the cardiopulmonary resuscitation machine body 1, so that the user can fold the folding arm 3 when not in use, reducing the space occupied by the overall structure and making it convenient for medical staff to carry when going out.

[0046] Two lifting arms 5 are respectively fixedly installed at the ends of the two folding arms 3 away from the main body 1 of the cardiopulmonary resuscitation machine. Each lifting arm 5 is equipped with a lifting button 6 for controlling the extension and retraction of the lifting arm 5. The lifting arm 5 is raised and lowered by controlling the lifting button 6, adjusting the distance between the bottom of the main body 1 of the cardiopulmonary resuscitation machine and the patient's chest. The machine also includes:

[0047] An annular groove 7 is provided on the end of the lifting arm 5 away from the folding arm 3;

[0048] The backplate structure has through holes 9 at both ends that align with the bottom end of the lifting arm 5. A locking box 11 is fixedly connected to the backplate structure below the through holes 9. A locking device is embedded in the inner cavity of the locking box 11. The locking device is used to fix the bottom end of the lifting arm 5 in conjunction with the annular groove 7. An unlocking device is also installed on the outer wall of the locking box 11. The structure also includes:

[0049] The back panel structure is an external back panel 18 located below the main body 1 of the cardiopulmonary resuscitation machine. Both ends of the external back panel 18 are fixedly connected to pads 19. A through hole 20 is also provided on the external back panel 18 above the pads 19.

[0050] When it is necessary to perform cardiopulmonary resuscitation (CPR) on a patient outside the hospital, the patient can be laid flat on the outer back panel 18. The two folding arms 3 are manually rotated outward to unfold them. After unfolding the folding arms 3, they are fixed by the folding button 4. Then, the lifting arm 5 is extended to its longest position by the lifting button 6. The bottom end of the lifting arm 5 can then pass through the through hole 9 on the outer back panel 18 and be inserted into the locking box 11 through the limiting hole 12. Since the bottom end of the lifting arm 5 has a hemispherical structure, the lifting arm 5 will squeeze the two locking slide plates 13 to slide in the opposite direction when inserted into the locking box 11 until the annular groove 7 at the bottom end of the lifting arm 5 is aligned with the notch on the locking slide plate 13. At this time, the two locking slide plates 13 are pushed into the annular groove 7 from both sides by the elastic force of the spring 15, locking the bottom end of the lifting arm 5. The medical staff can then adjust the main body 1 of the CPR machine to a suitable height by the lifting button 6 and start the CPR machine to rescue the patient.

[0051] Both ends of the back of the outer back panel 18 are fixedly connected to pads 19, which can support the outer back panel 18 from below. The through holes 20 can effectively reduce the weight of the outer back panel 18, making it easier for medical staff to carry.

[0052] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
