Description

Technical Field

[0001] This application relates to the field of cardiopulmonary resuscitation (CPR) teaching equipment technology, and in particular to a CPR teaching aid. Background Technology

[0002] Cardiopulmonary resuscitation (CPR) instruction is a systematic and standardized educational process based on evidence-based medicine, integrating knowledge transfer, skills training, attitude development, and decision-making practice.

[0003] Existing technologies offer a variety of auxiliary teaching devices. For example, the CPR self-service teaching device with authorization notice number CN214335962U is equipped with dual screens for easy viewing by both teachers and students, and its adjustable pedals can accommodate operators of different heights. Another example is the emergency CPR device with authorization notice number CN218187257U, which uses a positioning sliding plate to adapt to the patient's body shape and a spring structure to limit the depth and force of chest compressions; its principle is also applicable to teaching scenarios.

[0004] However, CPR training often requires flexible switching of teaching locations depending on the participants, which places high demands on the portability of equipment. The aforementioned equipment all have significant limitations in actual transport: self-service CPR teaching equipment is usually large and difficult to move; while emergency CPR devices, although advertised as "portable," are actually separate from the necessary teaching mannequins, and their own structures (such as sliding plates and hand connection components) often cannot be folded or compactly stored. Instructors need to pack the device and the mannequin separately, which not only takes up space and increases the burden of transportation but also easily leads to damage or loss of parts. Therefore, carrying the aforementioned equipment or devices may be relatively inconvenient for different teaching scenarios. Utility Model Content

[0005] The technical problem to be solved by this application is to provide a cardiopulmonary resuscitation teaching tool that can improve portability in mobile teaching scenarios.

[0006] To solve the above-mentioned technical problems, this application adopts the following technical solution:

[0007] A cardiopulmonary resuscitation (CPR) teaching aid includes a box for storing a mannequin, the box comprising a bottom plate, a left side plate, a right side plate, a front side plate, a rear side plate, and a top plate, wherein all plates except the bottom plate can be flattened;

[0008] An adjustment assembly is provided on the inner wall of the left side panel of the box. The adjustment assembly includes two fixing rods, which are rotatably housed on the left side panel.

[0009] The inner wall of the left side plate is also provided with a diagonal brace for fixing the left side plate upright, and the bottom of the diagonal brace abuts against the bottom plate of the box body;

[0010] An auxiliary pressing assembly is installed between the two fixed rods. The auxiliary pressing assembly includes a crossbar, a first pressing rod that can slide up and down is provided in the middle of the crossbar, a first pressing pad is provided at the bottom of the first pressing rod, a hollow second pressing rod is sleeved on the top of the first pressing rod, a second pressing pad is provided on the top surface of the second pressing rod, and a tightening element for locking is provided on the side wall of the second pressing rod.

[0011] In some embodiments, a downwardly extending vertical groove is formed in the middle of the inner wall of the left side plate, and the fixing rod is hinged to the top of the vertical groove. When the fixing rod is in the retracted state, it is located within the vertical groove. This solves the problem of adjusting component storage during the transfer of teaching aids.

[0012] In some embodiments, the top surface of the fixing rod is provided with a horizontally arranged connecting plate, the connecting plate having a through hole, and a first bolt being disposed within the through hole. The first bolt passes through the through hole and is threadedly connected to the left side plate. This solves the problem of how to fix the fixing rod.

[0013] In some embodiments, the bottom of the diagonal brace has a bend with a through hole. A second bolt is installed in the through hole, passing through it and threadedly connected to the base plate. This solves the problem of how to fix the diagonal brace to the base plate of the housing.

[0014] In some embodiments, a third bolt is fixed to the bottom of each end of the crossbar, and the top surfaces of the two fixing rods are respectively provided with through holes that match the third bolts. The third bolts pass through the corresponding through holes and are locked in place by nuts. This solves the problem of how to detachably fix the crossbar to the fixing rods.

[0015] In some embodiments, a threaded hole is provided on the side of the second pressing rod, and the tightening element is threaded into the threaded hole. This addresses the issue of how to adjust the pressing depth during instruction.

[0016] In some embodiments, fasteners are provided between the outer walls of the left side panel, front side panel, and rear side panel and the top panel to solve the problem of how to assemble and secure the enclosure.

[0017] Compared with the prior art, this application achieves at least the following beneficial effects: The cardiopulmonary resuscitation teaching aid is designed to be flattened, and the adjustment connector and auxiliary compression component for adjusting different compression depths to simulate different objects are integrated into the box. The overall structure is compact. When the mannequin is placed in the box, during transportation, since the box, auxiliary compression component for teaching and mannequin form an integrated structure, there is no need for separate packaging, saving space and improving portability to different teaching locations.

Therefore, they should not be construed as limiting the scope of protection of this application.

[0046] like Figure 1-6 As shown, in at least one embodiment of the cardiopulmonary resuscitation teaching aid of this application, a box (the material of which can refer to medical boxes, supply boxes, etc.) for storing a mannequin 70 is included. The box includes a bottom plate 8, a left side plate 1, a right side plate 4, a front side plate 5, a rear side plate 6, and a top plate 3. The bottom plate 8 is hinged to the left side plate 1, the right side plate 4, and the front side plate 5 by at least two hinges 7. The right side of the top plate 3 is also hinged to the upper middle part of the right side plate 4 by at least two hinges 7. Except for the bottom plate 8, the other plates can be flattened to the desired height by the action of the hinges 7. Figure 5 or Figure 6In this state, teaching and practice are conducted. To ensure smooth flattening of the box, mounting grooves 81 for embedding hinges 7 are provided on the inner side walls of the bottom plate 8, left side plate 1, right side plate 4, front side plate 5, rear side plate 6, and top plate 3. After the hinges 7 are installed, the axis of rotation of the hinge 7 is coaxial with the four top edges of the bottom plate 8 and the corresponding hinge edges of the left side plate 1, right side plate 4, and front side plate 5, as well as with the top edge of the right side plate 4 and the bottom right edge of the top plate 3.

[0047] An adjustment assembly is provided on the inner wall of the left side panel 1 of the box. The adjustment assembly includes two fixed rods 10 with a certain width, which are rotatably stored on the left side panel 1.

[0048] The inner wall of the left side plate 1 is also provided with a diagonal brace 9 for fixing the left side plate 1 upright, and the bottom of the diagonal brace 9 abuts against the bottom plate 8 of the box.

[0049] An auxiliary pressing component 40 is installed between the two fixed rods 10 to allow trainees to experience different pressing depths. The auxiliary pressing component 40 includes a crossbar 401, which is fixedly resting on the top surface of the two fixed rods 10. A through hole is opened in the middle of the crossbar 401, and a cylindrical first pressing rod 404 that can slide up and down is installed in the through hole. A first pressing pad 406 is fixedly connected to the bottom of the first pressing rod 404. The first pressing pad 406 is used to simulate the trainee's hand and includes a circular metal plate with a size similar to a human hand. A leather pad is glued or sewn to the bottom of the metal plate. The leather pad is filled with elastic padding such as sponge, making the leather pad slightly bulge. The design closely resembles the shape of a person's hand during CPR. A cylindrical second pressing rod 403 is fitted onto the top of the first pressing rod 404. The second pressing rod 403 can slide up and down on the first pressing rod 404. A second pressing pad 402 is provided on the top surface of the second pressing rod 403. The structure of the second pressing pad 402 is the same as that of the first pressing pad 406, except that the pad is placed on top of the metal plate, and the metal plate is smaller in size, making it easier for the trainee to hold and press. The side wall of the second pressing rod 403 is provided with a locking element to prevent the second pressing rod 403 from sliding along the first pressing rod 404 when using the auxiliary pressing assembly 40.

[0050] A downward-extending vertical groove 13 is provided in the middle of the inner wall of the left side plate 1. A shaft head is provided on the top left and right side walls of the fixing rod 10. A countersunk hole for placing the shaft head is provided on the top left and right inner walls of the vertical groove 13, so that the fixing rod 10 and the vertical groove 13 form a hinged connection. When the fixing rod 10 is in the retracted state (i.e., swinging downward), the fixing rod 10 is located in the vertical groove 13.

[0051] A horizontally arranged connecting plate 101 is welded to the top surface of the fixing rod 10. A threaded through hole is provided at the front end of the connecting plate 101, and a first bolt 20 is provided in the threaded through hole. A threaded hole 11 is provided on the inner wall of the left side plate 1, above the vertical groove 13. The first bolt 20 passes through the threaded through hole of the connecting plate 101 and is threadedly connected to the left side plate 1 through the threaded hole 11. The purpose of setting the fixing rod 10 as an unfoldable / foldable structure is to avoid damage caused by hard contact between its edge and the model man 70 when it is in the carrying state (when the fixing rod 10 is in the unfolded position), and to prevent damage to the connection point that may be caused by the shaking of the end of the fixing rod 10 due to bumps.

[0052] The side wall of the vertical groove 13 is also provided with a clearance slot 12, which exposes the side of the fixing rod 10. When it is necessary to unfold the fixing rod 10, the fixing rod 10 can be engaged through the clearance slot 12.

[0053] When unfolding the fixing rod 10, first swing the fixing rod 10 upwards until it is parallel to the base plate 8. At this time, the connecting plate 101 and the inner wall of the left side plate 1 are in contact, and the first bolt 20 and the threaded hole 11 of the left side plate 1 are coaxial. Then, the first bolt 20 is screwed into and tightened into the threaded hole 11 of the left side plate 1, completing the unfolding and fixing of the fixing rod 10. After unfolding, the right end of the fixing rod 10 is exactly above the chest cavity of the model man 70.

[0054] The function of the diagonal brace 9 is to hold the left side plate 1 in place after it is erected, preventing it from tilting. Therefore, the top surface of the diagonal brace 9 is fixedly connected to the left side plate 1. The bottom of the diagonal brace 9 is provided with a bend 91. The bottom surface of the bend 91 is flush with and in contact with the bottom plate 8. The top surface of the bend 91 is provided with a threaded through hole. A second bolt 30 is provided in the threaded through hole. The bottom of the bottom plate 8 is also provided with a threaded hole (not shown in the attached figure due to obstruction). The second bolt 30 passes through the through hole and is threadedly connected to the threaded hole on the bottom plate 8.

[0055] There are two of each, including the fixed rod 10 and the diagonal brace 9, to balance the corresponding forces.

[0056] Tighten the second bolt 30, and the diagonal brace 9 will support the left side plate 1 to keep it upright. Loosen and remove the second bolt 30 so that it is not connected to the base plate 8, and the left side plate 1 can be flattened.

[0057] The auxiliary pressing component 40 is used to allow trainees to experience different pressing depths. It is detachably installed on the right end of the unfolded fixed rod 10. For the detachable installation method, vertically downward third bolts 4011 are welded to the bottom of both ends of the crossbar 401. The top surface of the right end of the two fixed rods 10 is provided with through holes that match the third bolts 4011. The third bolts 4011 pass through the corresponding through holes and are locked and fixed by nuts, so that the crossbar 401 is fixed on the two fixed rods 10.

[0058] The tensioning element is used to fix the position of the second pressing rod 403 on the first pressing rod 404. The second pressing rod 403 has a screw hole on its side. The tensioning element is a fourth bolt 405, which is threaded into the screw hole.

[0059] The outer wall of the first pressing rod 404 is marked with graduations.

[0060] During assembly, insert the first pressing rod 404 into the through hole of the crossbar 401, then place the second pressing rod 403 on top of the first pressing rod 404 and slightly tighten the fourth bolt 405. Next, install the crossbar 401 onto the fixing rod 10 using the third bolt 4011. At this point, the first pressing pad 406 is positioned above the area on the mannequin 70 where CPR is being performed. Loosen the fourth bolt 405 to allow the second pressing rod 403 to slide upwards a specified distance to adjust the compression depth (the compression depth should be at least 5 cm (not exceeding 6 cm) for adults, approximately 5 cm for children, and approximately 4 cm for infants). For example, sliding the second pressing rod 403 upwards between 5 cm and 6 cm simulates adult CPR, approximately 5 cm simulates child CPR, and approximately 4 cm simulates infant CPR. After adjustment, tighten the fourth bolt 405 to fix the second pressing rod 403 onto the first pressing rod 404. Since the outer diameter of the second pressing rod 403 is larger than the inner diameter of the through hole on the crossbar 401, when pressed down, the bottom surface of the second pressing rod 403 contacts the top surface of the crossbar 401 to form a limit, preventing the entire auxiliary pressing assembly 40 from moving excessively downward.

[0061] Except for the third bolt 4011, the first bolt 20, the second bolt 30 and the fourth bolt 405 are all wing bolts, which are convenient for operators to loosen / tighten by hand.

[0062] like Figure 1-3 As shown, latches 2 (existing products) are installed between the outer walls of the left side panel 1, front side panel 5, and rear side panel 6 and the top panel 3. When the box is closed, the latches 2 are locked to prevent the box from unfolding.

[0063] A U-shaped handle 31 groove is provided on the top surface of the top plate 3. A handle 31 is hinged in the handle 31 groove. When the box is flat, the handle 31 sinks into the handle 31 groove, so that the top plate 3 can fit with the ground.

[0064] On the inner wall of the front panel 5, a rectangular hollow storage basket 50 is fixedly connected (by glue or bolts) for placing the disassembled auxiliary compression assembly 40. On the inner wall of the right panel 4, a mat 90 is attached. Considering that medical staff usually perform CPR in a kneeling position, the mat 90 can improve the comfort of the medical staff's knees.

[0065] The base plate 8 is also fitted with a first strap 60 and a second strap 80 for securing the model figure 70. The base plate 8 has hook-and-loop fasteners, and the ends of the first strap 60 and the second strap 80 are respectively fitted with hook-and-loop loop fasteners. The first strap 60 is used to secure the model figure 70 around its neck, and the second strap 80 is used to secure the model figure 70 around its waist. This prevents the model figure 70 from shaking excessively inside the box.

[0066] The arrangement of the model man 70 in this embodiment is only for example purposes. The head of the model man 70 can also face the front side panel 5 without affecting the teaching.

[0067] When taking it out, place the model figure 70 inside the case and secure it with the first strap 60 and the second strap 80 (at this time, the fixing rod 10 is in the storage state, and the auxiliary pressing component 40 is kept inside the storage basket 50). Cover the top plate 3 and check that the buckles 2 on the front side plate 5, the left side plate 1, and the rear side plate 6 are fastened to prevent the case from unfolding during carrying (the internal effect is as shown). Figure 2 and Figure 3 (Demonstration), then grasp the handle 31 on the top plate 3 to go outside.

[0068] There are two modes for teaching CPR using this teaching aid: mode with auxiliary compression component 40 and mode without auxiliary compression component 40.

[0069] When using the auxiliary press component in mode 40:

[0070] First, flatten the entire box.

[0071] After the latch 12 is engaged and the two fixing rods 10 are raised from the left side plate 1, the first bolt 20 on the connecting plate 101 is screwed into the threaded hole of the left side plate 1 to prevent the fixing rods 10 from swinging.

[0072] Remove the auxiliary pressing component 40 from the storage basket 50 and install it on the fixing rod 10 as described above;

[0073] Erect the left side plate 1 so that it is perpendicular to the base plate 8. At this time, the bend 91 at the bottom of the diagonal brace 9 contacts the top surface of the base plate 8. Screw the second bolt 30 on the bend 91 into the threaded hole on the base plate 8 so that the diagonal brace 9 and the base plate 8 form a fixed connection and the left side plate 1 is stably erected.

[0074] Then, adjust the pressing depth of the auxiliary pressing component 40 as described above. After adjustment, the structure of the teaching aid is as follows: Figure 4 As shown, trainees can kneel on the mat 90 on the right side board 4 and hold the second compression pad 402 with both hands to simulate CPR compressions.

[0075] After a period of practice, the trainee has roughly mastered the pressing depth. At this point, the mode without using the auxiliary pressing component 40 can be switched: loosen the second bolt 30 at the bend 91 of the diagonal brace 9, so that the left side plate 1 is as... Figure 5 When flattened as shown, CPR can be performed without the aid of compression component 40.

[0076] After the teaching is completed, Figure 5 For final use, first remove the auxiliary pressing component 40 and put it back into the storage basket 50. Then loosen the first bolt 20 and swing the fixing rod 10 into the vertical slot 13. Then, in sequence, stand up the left side panel 1, right side panel 4, front side panel 5 and rear side panel 6 and cover it with the top panel 3. Finally, fasten the buckles 2 on the left side panel 1, front side panel 5 and rear side panel 6 and the top panel 3 to complete the storage.

[0077] It should be understood that all the above embodiments are exemplary and not restrictive. Various modifications or variations made by those skilled in the art to the specific embodiments described above under the concept of this application should be within the protection scope of this application.
