Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a bandage for use in cardiopulmonary resuscitation equipment. Background Technology
[0002] Cardiopulmonary resuscitation (CPR) equipment typically uses bandages to restrain the patient's chest cavity, preventing it from expanding outwards or allowing the chest to contract actively. Traditional products employ a one-piece design, achieving fixation only through simultaneous tightening from both sides. In emergency situations, medical personnel must spend extra time installing the bandages, significantly impacting the critical window for rescue. Therefore, the applicant seeks to improve the bandages used in CPR equipment. Utility Model Content

[0024] To facilitate understanding of this utility model, a more comprehensive description will be given below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.
[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0026] Current CPR equipment uses a one-piece bandage design, which suffers from compatibility issues. Traditional bandages can only achieve fixation by tightening simultaneously from both sides. This structural characteristic necessitates the availability of multiple sizes to accommodate patients of different body types. In emergency situations, medical personnel must spend extra time matching the correct size, severely impacting the critical window for rescue. Traditional bandages also have operational positioning defects. The symmetrical tightening method of existing products requires rescuers to apply force with both hands simultaneously. In practice, uneven force application on both sides can easily cause axial displacement of the CPR equipment, directly affecting the accuracy of compression positioning. Furthermore, the two-handed operation mode limits the rescuer's other emergency response capabilities and poses a risk of secondary medical intervention.
[0027] Figure 1 This is a top view of a bandage used in a cardiopulmonary resuscitation device in one embodiment of this application. Figure 2 This is a bottom view schematic diagram of a bandage used in a cardiopulmonary resuscitation device according to one embodiment of this application. Figure 1 The diagram shown is a top view of the structure with the bandages fixed to the cardiopulmonary resuscitation equipment in the deployed state. Figure 2 The diagram shows a top-down view of the structure with the bandages fixed to the cardiopulmonary resuscitation (CPR) device and in the unfolded state. L1 represents the distance from the side of the first bandage 100 furthest from the CPR device 10 to the first side of the CPR device 10. L2 represents the distance from the side of the second bandage 200 furthest from the CPR device 10 to the second side of the CPR device 10. L1' represents the distance from the side of the first bandage 100 closest to the CPR device 10 to the first side of the CPR device 10. W represents the length of the CPR device 10.
[0028] In one embodiment, the bandage provided in this application for use in a cardiopulmonary resuscitation (CPR) device may include a first bandage 100 and a second bandage 200 that are independent of each other, wherein the length of the first bandage 100 is less than the length of the second bandage 200. A first fixing member 11 and a second fixing member 13 may be respectively provided on a first side and a second side opposite to each other of the CPR device 10. One end of the first bandage 100 may be connected to the first fixing member 11, and one end of the second bandage 200 may be connected to the second fixing member 13. A first connecting member 110 may be provided on the first surface of the first bandage 100, and a second connecting member 210 may be provided on the second surface of the second bandage 200. The first bandage 100 and the second bandage 200 may be fixed together by the first connecting member 110 and the second connecting member 210.
[0029] The shorter first bandage 100 is fixed to the first side of the cardiopulmonary resuscitation (CPR) device 10 via the first fastener 11, and the longer second bandage 200 is fixed to the second side of the CPR device 10 via the second fastener 13. The bandage design provided in this application for use in a CPR device is a two-section bandage, with both sections fixed to the CPR device 10 via single-end fixation. This single-end fixation of the two sections reduces the risk of the CPR device 10 shifting its center, facilitating single-person operation. Furthermore, the single-end fixation method also reduces the total length of the bandage.
[0030] In application, the longer second bandage 200 can be wrapped around the patient's body. After wrapping around the patient's body, the second bandage 200 is fixed to the shorter first bandage 100 to restrain the patient. That is, a bandage on one side wraps around the chest cavity and is fixed and tightened to the bandage on the other side, restricting the patient's chest cavity between the cardiopulmonary resuscitation device 10 and the bandage. When the cardiopulmonary resuscitation device 10 is working, the bandage can prevent the patient's chest cavity from expanding outward, thus ensuring the effectiveness of the cardiopulmonary resuscitation device 10 in compressing the patient's chest cavity.
[0031] This design allows users to quickly and securely fasten patients to the CPR device 10, ensuring patient stability and the effectiveness of the procedure during CPR. Simultaneously, the design of the first connector 110 and the second connector 210 allows for easy connection or separation between the two bandages. Furthermore, adjusting the length of the longer second bandage 200 allows for adaptation to patients with different chest circumferences, reducing bandage selection time and increasing emergency response time. Different lengths of the second bandage 200 can adapt to different usage scenarios or needs, reducing the risk of the CPR device 10 not being securely fastened after an incorrect bandage selection.
[0032] In one embodiment, the first connector 110 and the second connector 210 are Velcro. Since Velcro can accommodate a certain degree of size difference, the method by which the first bandage 100 and the second bandage 200 are secured using the first connector 110 and the second connector 210 can be suitable for patients of different body types, increasing the flexibility of bandage use. When the first connector 110 and the second connector 210 are properly bonded, they provide sufficient fixing force to ensure that the patient remains in a stable operating position relative to the CPR device 10 during CPR, reducing the risk of secondary injury caused by moving the CPR device 10.
[0033] In one specific embodiment, the first connector 110 may be the hook side of the hook and loop fastener, and the second connector 210 may be the loop side of the hook and loop fastener; or, the first connector 110 may be the loop side of the hook and loop fastener, and the second connector 210 may be the hook side of the hook and loop fastener.
[0034] In one embodiment, the first surface of the first bandage 100 and the second surface of the second bandage 200 may be on different planes. For example, the first surface of the first bandage 100 may be the front side of the first bandage 100, and the second surface of the second bandage 200 may be the back side of the second bandage 200. A portion of the back side of the second bandage 200 may be the contact surface with the patient, and the second bandage 200 is bonded and fixed to the first bandage 100 after being wrapped around the patient's body.
[0035] In one embodiment, the width of the first connector 110 and the width of the second connector 210 can both be greater than or equal to 80 mm, and the length of the first connector 110 can be greater than or equal to 100 mm.
[0036] In one embodiment, the width of the first connector 110 and the width of the second connector 210 are in the range of 80mm to 160mm, and the length of the first connector 110 is in the range of 100mm to 220mm.
[0037] Experiments have shown that when the width of the hook and loop fastener interface is ≥100mm and the length is ≥120mm, a secure bond between the two sections of bandage can be ensured, preventing loosening or displacement. Therefore, in this embodiment, preferably, the width of the first connector 110 and the second connector 210 can be designed to be ≥100mm, and the length of the first connector 110 can be designed to be ≥120mm, to ensure effective binding between the first connector 110 and the second connector 210. In a preferred embodiment, the width of the first connector 110 and the width of the second connector 210 can be 100mm, and the length of the first connector 110 can be 200mm.
[0038] Figure 3 This is a top view of a bandage used in a cardiopulmonary resuscitation device according to another embodiment of this application. Figure 4This is a bottom view schematic diagram of a bandage applied to a cardiopulmonary resuscitation (CPR) device according to another embodiment of this application. Wherein, L1 represents the distance from the side of the first bandage 100 furthest from the CPR device 10 to the first side of the CPR device 10; L2 represents the distance from the side of the second bandage 200 furthest from the CPR device 10 to the second side of the CPR device 10; L1' represents the distance from the side of the first bandage 100 closest to the CPR device 10 to the first side of the CPR device 10; W represents the length of the CPR device 10; L3 represents the distance between the side of the second connector 210 furthest from the rigid section 220 and the second side of the CPR device 10; L2' represents the length of the second connector 210; and L4 represents the length of the rigid section 220.
[0039] In one embodiment, the end of the second bandage 200 furthest from the second fastener 13 may have a rigid section 220. The rigid section 220 may include a first fabric layer, a rigid plate layer, and a second fabric layer stacked together. The second bandage 200 may have two opposing ends, one of which is fixed to the second fastener 13, and the other end has the rigid section 220. The rigid plate layer of the rigid section 220 provides a certain degree of rigidity, ensuring that the second bandage 200 will not easily bend or fold during insertion, allowing the second bandage 200 to pass smoothly through narrow spaces or closely conform to the body's curves. The first and second fabric layers wrap around the rigid plate layer, which can reduce friction damage to the patient's skin during insertion and also provides a more comfortable contact surface.
[0040] The rigid section 220 is designed to allow the second bandage 200 to pass more easily across the patient's back while the patient is lying down, reducing the need to move the patient and thus avoiding potential additional discomfort or injury. In emergency situations, this design helps first responders complete immobilization more quickly.
[0041] In one embodiment, one side of the second connector 210 may coincide with one side of the rigid section 220. That is, the surface of the rigid section 220 does not cover the second connector 210, and the second connector 210 is disposed adjacent to the rigid section 220. Since the rigid section 220 is mainly used for support and guidance of the second bandage 200 during the insertion process, if Velcro is placed on it, it may increase friction with the patient's body or clothing during insertion, causing discomfort or inconvenience. Placing the second connector 210 next to the rigid section 220 can avoid this situation.
[0042] In one embodiment, the distance L3 between the side of the second connector 210 away from the rigid section 220 and the second side of the cardiopulmonary resuscitation device 10 satisfies L3 = A - L1' - Wx. Here, A is the minimum chest circumference. L1' is the distance between the side of the first connector 110 near the cardiopulmonary resuscitation device 10 and the first side of the cardiopulmonary resuscitation device 10, W is the length of the cardiopulmonary resuscitation device 10, and x is a reference constant. The units of L3, A, L1', W, and x are all mm.
[0043] In one embodiment, considering that the bonding strength between the hook and loop fastener interfaces of hook and loop fasteners made of different materials may vary, the value of x can be determined based on the bonding strength requirements of the hook and loop fastener interfaces. x can be a fixed constant. For example, when the bonding length of the hook and loop fastener interfaces needs to be ≥120mm to ensure a firm bond between the two hook and loop fasteners, and considering the production and application costs of the bandage, the value of x can be selected as 120mm.
[0044] In one embodiment, the length L2' of the second connector 210 satisfies L2' = B + xW - L1 - L3, where B is the maximum chest circumference, L1 is the distance between the side of the first connector 110 furthest from the cardiopulmonary resuscitation device 10 and the first side of the cardiopulmonary resuscitation device 10, and the units of L2', B, and L1 are all mm. The length of the second bandage 200 can be designed by comprehensively considering the strength of the hook and loop fastener adhesive surface and the chest dimensions of different patients. Clinical measurements show that the anteroposterior diameter of the chest in the adult population in my country ranges from 710 to 1370 mm.
[0045] In one embodiment, L1 ranges from 220mm to 260mm, L1' ranges from 40mm to 80mm, W ranges from 180mm to 220mm, L4 ranges from 140mm to 180mm, and x ranges from 100mm to 140mm. In a preferred embodiment, L1 = 240mm, L1' = 60mm, W = 200mm, L4 = 160mm, and x = 120mm.
[0046] In this embodiment, taking the parameters L1 = 240mm, L1' = 60mm, W = 200mm, L4 = 160mm, A = 710mm, B = 1370mm, and x = 120mm as examples, the determination of the length of the second bandage 200 based on the minimum and maximum chest circumference calculation formulas will be explained. Here, L4 is the length of the rigid section 220.
[0047] Minimum chest circumference calculation formula: A=W+L3+L1'+x
[0048] Maximum chest circumference calculation formula: B=W+L1+L3+L2'-x
[0049] Substituting the above parameters into the minimum chest circumference calculation formula, L3 = 330mm can be calculated, meaning the distance L3 between the side of the second connector 210 furthest from the rigid section 220 and the second side can be designed to be 330mm. After determining L3, substituting it into the maximum chest circumference calculation formula, L2' = 720mm can be calculated. The length of the second bandage 200 is L2 = L3 + L2' + L4 = 1210mm. By designing the length of the second bandage 200 to 1210mm, it can adapt to the anteroposterior diameter range of 710-1370mm, and ensures that the width of the Velcro fastener joint surface between the first bandage 100 and the second bandage 200 is ≥100mm and the length is ≥120mm.
[0050] The bandage provided in this application is designed based on the length of the second bandage 200 mentioned above, ensuring that the bandage can be adapted to patients of different body types during use, eliminating the need to set different length specifications for the bandage. Furthermore, in emergency situations, medical personnel do not need to spend extra time matching the bandage size to the patient's body type, improving rescue efficiency.
[0051] Figure 5 This is a top view of a bandage used in a cardiopulmonary resuscitation device 10 in another embodiment of this application. In one embodiment, a third connector 230 is provided on the first surface of the second bandage 200, one side of the third connector 230 coincides with one side of the rigid section 220, and a fourth connector 240 is provided on the first surface of the rigid section 220.
[0052] When performing CPR on patients with small chest cavities, the second bandage 200 may have a section remaining after being secured to the first bandage 100, which could hinder emergency procedures. In this embodiment, by providing a third connector 230 on the first surface of the second bandage 200 and a fourth connector 240 on the first surface of the rigid section 220, the excess bandage can be folded and secured. Figure 6 This is a schematic diagram of the structure for folding excess bandage in one embodiment of this application. Velcro is designed on the reverse side of the second bandage 200 to fold and fix the excess length, preventing the excess bandage from swinging or dragging at will, and reducing interference with medical operations or other emergency procedures.
[0053] In one embodiment, the first surface of the first bandage 100, the first surface of the second bandage 200, and the first surface of the rigid segment 220 may be on the same plane. For example, the first surface of the first bandage 100 may be the front side of the first bandage 100, and the first surface of the second bandage 200 may be the front side of the second bandage 200.
[0054] In one embodiment, the third connector 230 and the fourth connector 240 are hook and loop fasteners. In a specific embodiment, the third connector 230 may be the hook side of the hook and loop fastener, and the fourth connector 240 may be the loop side of the hook and loop fastener; or, the third connector 230 may be the loop side of the hook and loop fastener, and the fourth connector 240 may be the hook side of the hook and loop fastener.
[0055] In one embodiment, a loop is attached to the end of the first bandage 100 away from the first fixing member 11. That is, the first bandage 100 has two opposing ends, one fixed to the first fixing member 11 and the other fixed with a loop. The loop at the end of the first bandage 100 facilitates quick lifting of equipment by emergency responders. In emergencies, every second counts. The loop design allows emergency responders to rapidly move the equipment to the required location, thereby improving the efficiency of rescue efforts.
