Description

Technical Field

[0001] The present invention relates to the technical field of cardiopulmonary resuscitation training, and in particular to a training device for cardiopulmonary resuscitation. Background Art

[0002] Cardiopulmonary resuscitation is a life-saving technique for a stopped heart and breathing, aiming to restore the patient's spontaneous breathing and spontaneous circulation. The standard for high-quality cardiopulmonary resuscitation actions is that the compression depth is about 5 cm for adults and about 4 cm for children. Since each person has a different body posture, in order to achieve the same depth, different forces are required. To strengthen the training of the trainee's sense of compression depth distance, a training device for cardiopulmonary resuscitation is proposed.

[0003] In the prior art, most of the compression mechanisms in cardiopulmonary resuscitation training devices are composed of simple structures such as springs, enabling trainees to perform action training. However, since the resistance provided by the spring is related to its telescopic displacement and spring coefficient, and the spring coefficient is not easy to adjust, it follows that after the existing device is pressed to the standard depth, the resistance felt by the trainee's palm from the existing device is the same. Although the standard compression depth can be achieved, long-term use of this kind of training device for training will cause the trainee to judge the compression depth based on the force received by the palm. Therefore, in actual operation, due to different patient body postures, the compression depth may be insufficient. For example, obese patients may require greater force to reach a sufficient depth, while thin patients may have different force sensations, but the actual depth may already be sufficient or excessive. In addition, most cardiopulmonary resuscitation training devices use electronic devices such as sensors and controllers to digitally reflect the compression depth in real time, but the numbers are not convenient for trainees to understand the underlying logic of cardiopulmonary resuscitation and are not conducive to the in-depth understanding of trainees.

In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0024] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] The following will be combined with Figures 1 to 10 As shown in the figure, an embodiment of the present invention provides a training device for cardiopulmonary resuscitation, including: A base 1, a leather sleeve 201 is fixed on the top of the base 1, and a plate body 807 is fixed on the inner wall of the top of the leather sleeve 201; A metal box 202, the metal box 202 is fixed in the leather sleeve 201; Two adjusting components, both of the two adjusting components are fixed on the top of the metal box 202, and both of the two adjusting components are fixed to the plate body 807; Two buffer components, both of the two buffer components are fixed to the base 1; A display component, the display component is communicated with the two buffer components; A storage component, the storage component is communicated with the display component and the two buffer components, and both of the two adjusting components are communicated with the storage component; Among them, the adjusting component includes: A sleeve 801, the sleeve 801 is fixed on the top of the metal box 202, and a third piston 808 is slidably arranged in the sleeve 801; A sleeve rod 802, the sleeve rod 802 is fixed to the third piston 808, and the sleeve rod 802 is fixed to the plate body 807; A communication component, the communication component is fixed to the sleeve 801, and the communication component is located above the third piston 808. The communication component is used to cooperate with a vacuum pump to reduce the air pressure in the space of the sleeve 801 where the third piston 808 is located; An impact component, the impact component is arranged at the bottom of the sleeve 801, and the impact component is connected to the third piston 808.

[0026] Through the action of the communication component and in cooperation with the vacuum pump, the air pressure in the sleeve 801 above the third piston 808 is adjusted. When the air pressure here is lower, the greater the force required to push the third piston 808 downward. On the contrary, if the air pressure here is higher, the smaller the force required to push the third piston 808 downward. Therefore, in each training of this device, the required force can be appropriately adjusted to strengthen the sense of distance of the training pressing depth to ensure the quality of cardiopulmonary resuscitation actions; Through the display component and the storage component, during the pressing process, the gas in the sleeve 801 is injected into the storage component by the third piston 808. By using the force of this gas, the liquid can enter the display component to simulate the heart pumping effect during cardiopulmonary resuscitation, thereby strengthening the trainee's understanding of cardiopulmonary resuscitation.

[0027] Furthermore, it also includes: The first pipe body 803, the first pipe body 803 is connected to two sleeves 801, and the first pipe body 803 is located above the two third pistons 808; The second pipe body 804, the second pipe body 804 is connected to two sleeves 801, and the second pipe body 804 is located below the two third pistons 808.

[0028] Furthermore, the impact component includes: The connecting rod 810, the connecting rod 810 is fixed to the bottom of the sleeve 801; The hammer 811, the hammer 811 is slidably sleeved on the connecting rod 810. Two limiting grooves are provided on the inner wall of the hammer 811, and an inclined surface structure is provided on the top of the hammer 811; The cross groove 813, the cross groove 813 is provided on the top of the connecting rod 810; The transmission rod 814, the transmission rod 814 is slidably arranged in the cross groove 813; The fifth spring 817, one end of the fifth spring 817 is fixed to the transmission rod 814, and the other end of the fifth spring 817 is fixed to the inner wall of the cross groove 813; Two connecting rods 816, both of the two connecting rods 816 are rotatably connected to the transmission rod 814; Two limiting blocks 815, both of the two limiting blocks 815 are slidably connected to the cross groove 813, and the two limiting blocks 815 are respectively rotatably connected to the two connecting rods 816. The limiting blocks 815 are adapted to the limiting grooves; The fourth spring 812, the fourth spring 812 is fixed to the top of the hammer 811, and the fourth spring 812 is fixed to the third piston 808; The third spring 809, the third spring 809 is fixed to the third piston 808, and the third spring 809 is fixed to the inner wall of the bottom of the sleeve 801.

[0029] When the pressing depth is too large, the third piston 808 descends a large distance. The third piston 808 can abut against and push down the transmission rod 814 at the top of the connecting rod 810, while compressing the fourth spring 812. The descent of the transmission rod 814 drives the two brackets 805 to approach each other through the two connecting rods 816, so that the brackets 805 leave the limiting grooves on the hammer 811. After that, under the action of the fourth spring 812 in the compressed state, the hammer 811 is pushed to quickly strike the bottom of the sleeve 801, and cooperate with the metal box 202 at the bottom of the sleeve 801 to produce a sound, indicating that cardiopulmonary resuscitation of this degree will cause chest fractures and other conditions to the patient.

[0030] Further, the communication component includes: An air extraction pipe 301, the air extraction pipe 301 is communicated with one of the sleeves 801, and the air extraction pipe 301 is located above the third piston 808; A first one-way valve 302, the first one-way valve 302 is communicated with the air extraction pipe 301, and the air extraction pipe 301 penetrates through the leather sleeve 201; A plug 303, the plug 303 is arranged at the end of the air extraction pipe 301.

[0031] Through the action of the first one-way valve 302 and the vacuum pump, the gas in the air extraction pipe 301 is extracted, and in cooperation with the first pipe body 803, the air pressure above the third piston 808 in the two sleeves 801 is reduced, and the air pressure intensity is at the same level.

[0032] Further, the buffer component includes: A fixing plate 401, the fixing plate 401 is fixed to the base 1; A buffer tube 402, the buffer tube 402 is fixed to the top of the fixing plate 401; A third one-way valve 405, the third one-way valve 405 is arranged through the top of the buffer tube 402; A second one-way valve 403, the second one-way valve 403 is arranged through the top of the side wall of the buffer tube 402; A first piston 406, the first piston 406 is slidably arranged in the buffer tube 402; A first spring 407, the first spring 407 is fixed in the buffer tube 402, and the first spring 407 is fixed to the first piston 406.

[0033] Through the semi-circular structure of the semi-circular seat 701, it is convenient for the glitter powder to quickly settle at both ends of the bottom of the semi-circular seat 701. During the process of pressing down the plate body 807, the liquid entering the semi-circular seat 701 will also flow towards both ends of the semi-circular seat 701. The liquid in the semi-circular seat 701 enters the buffer tube 402 through the third one-way valve 405 and pushes the first piston 406 to descend. During this process, the liquid carries the glitter powder into the buffer tube 402; Further, the storage component includes: Storage tube 601, with a second connecting tube 602 provided at the top of the storage tube 601; Filter screen 603, fixed inside the storage tube 601; Connecting tube 404, connected to two second one-way valves 403, and the end of the connecting tube 404 penetrates through the top of the filter screen 603.

[0034] When the plate body 807 descends, two third pistons 808 are pushed downward by two sleeve rods 802. With the cooperation of the second tube body 804, during the descent of the third pistons 808, the gas below the third pistons 808 in the two sleeves 801 enters the connection tank 501 through the air delivery pipe 502, and the second piston 507 is pushed downward.

[0035] Furthermore, the storage assembly further includes: Support plate 503, fixed to the storage tube 601; Connection tank 501, fixed on the support plate 503; First connecting tube 504, one end of which penetrates through the bottom of the connection tank 501 and the side wall bottom of the storage tube 601; Second piston 507, slidably arranged inside the connection tank 501; Force sensor 505, fixed on the inner wall of the top of the connection tank 501; Second spring 506, one end of which is fixed to the force sensor 505 and the other end is fixed to the second piston 507; Air delivery pipe 502, penetrating through the side wall of the connection tank 501, and the air delivery pipe 502 is above the second piston 507. The air delivery pipe 502 penetrates through the bottom of the side wall of one of the sleeves 801.

[0036] During cardiopulmonary resuscitation, when pressing, the descent of the third piston 808 will inject the gas in the sleeve 801 into the connection tank 501 through the air delivery pipe 502, and push the second piston 507 downward to inject the liquid below the second piston 507 in the connection tank 501 into the storage tube 601 through the support plate 503; During the descent of the second piston 507, the force sensor 505 generates a signal intensity through the second spring 506, and the signal intensity of the force sensor 505 is related to the ascending and descending amplitudes of the second piston 507. Thus, by recording the data of the force sensor 505, the number and frequency of presses, the rebound depth, and the pressing depth during the entire training process can be recorded.

[0037] Furthermore, the display assembly includes: Semicircular seat 701, the semicircular seat 701 is connected to two third one-way valves 405, an installation hole is provided at the top of the semicircular seat 701, and the second connecting pipe 602 is disposed through the inner wall of the bottom of the semicircular seat 701; Transparent plate 702, the transparent plate 702 is fixed in the installation hole.

[0038] Through the transparent plate 702, it is convenient to observe the situation in the semicircular seat 701.

[0039] Furthermore, the storage pipe 601, the semicircular seat 701, and the space below the second piston 507 in the connection tank 501, and the space above the first piston 406 in the buffer pipe 402 are all filled with liquid. Glitter is placed above the filter screen 603 in the storage pipe 601.

[0040] When the liquid flows through the filter screen 603, it will carry the glitter on the filter screen 603 and enter the semicircular seat 701 together with the liquid. Through the properties of the glitter, it is convenient for the trainee to observe the amount of liquid entering the semicircular seat 701 during pressing, so as to increase the trainee's deeper understanding of the significance of cardiopulmonary resuscitation training.

[0041] Furthermore, it further includes: Bracket 805, the bracket 805 is fixed on the top of the metal box 202; Two support rods 806, both of the two support rods 806 are slidably connected to the bracket 805, and both of the two support rods 806 are fixed to the plate body 807.

[0042] The specific working method is: when in use, first connect the vacuum pump to the first one-way valve 302, and extract the gas in the suction pipe 301 through the vacuum pump and the first one-way valve 302. Through the action of the first pipe body 803, the air pressure above the third piston 808 in the two sleeves 801 is reduced. The smaller the air pressure above the third piston 808 in the sleeve 801, the greater the force required to push the third piston 808 down, so as to adjust the force required for cardiopulmonary resuscitation and simulate patients with different physiques; During the training action of performing cardiopulmonary resuscitation, when pressing, the root of the trainee's palm should touch the top of the leather sleeve 201 and press down, so as to push the plate body 807 down; When the plate body 807 descends, the two third pistons 808 are pushed downward by the two sleeve rods 802. With the cooperation of the second pipe body 804, when the third piston 808 descends, the gas below the third piston 808 in the two sleeves 801 is entered into the connection tank 501 through the air delivery pipe 502, and the second piston 507 is pushed down; When the second piston 507 descends, the liquid in the connection tank 501 below the second piston 507 is injected into the storage pipe 601 through the first connection pipe 504 and passes through the filter screen 603. During this process, the liquid carries the glitter above the filter screen 603 and enters the semi-circular seat 701 through the second connection pipe 602. At this time, the trainee can observe the glitter entering the semi-circular seat 701 through the transparent plate 702; When the pressing depth is relatively low, less liquid enters the semi-circular seat 701 through the second connection pipe 602, and thus less glitter is carried overall, indicating that cardiopulmonary resuscitation at this level will result in insufficient pump blood volume, and thus the pressing depth needs to be increased. Conversely, when the pressing depth is appropriate, more liquid enters the semi-circular seat 701 through the second connection pipe 602, and thus more glitter is carried. By observing the amount of glitter, it is possible to determine in real time whether the pressing depth meets the standard; When the pressing depth is too large, the third piston 808 descends a large distance. The third piston 808 can contact and push the transmission rod 814 at the top of the connecting rod 810 to descend, while compressing the fourth spring 812. The descent of the transmission rod 814 drives the two brackets 805 to approach each other through the two connecting rods 816, so that the brackets 805 leave the limiting groove on the hammer 811. After that, under the action of the fourth spring 812 in the compressed state, the hammer 811 is pushed to quickly strike the bottom of the sleeve 801, and cooperate with the metal box 202 at the bottom of the sleeve 801 to produce a sound, indicating that cardiopulmonary resuscitation at this level will cause the patient's chest fracture and other conditions; Due to the semi-circular structure of the semi-circular seat 701, it is convenient for the glitter to quickly settle at both ends of the bottom of the semi-circular seat 701. During the process of pressing down the plate body 807, the liquid entering the semi-circular seat 701 will also flow towards both ends of the semi-circular seat 701. The liquid in the semi-circular seat 701 enters the buffer pipe 402 through the third one-way valve 405 and pushes the first piston 406 to descend. During this process, the liquid carries the glitter into the buffer pipe 402. When the trainee stops applying pressure to the plate body 807, during the rebound process of the plate body 807, at this time, under the negative pressure above the third piston 808 in the sleeve 801 and the action of the third spring 809, the third piston 808 is reset. During the reset process of the third piston 808, the second piston 507 is also synchronously reset through the action of air pressure, and at the same time, in cooperation with the first spring 407, the first piston 406 is pushed to reset. During this process, the first piston 406 returns the liquid and glitter in the buffer pipe 402 into the storage pipe 601 through the second one-way valve 403 and the connecting pipe 404, and enters the position above the filter screen 603. Through the filtration of the filter screen 603, the glitter is left on the filter screen 603, while the liquid returns to the connection tank 501 through the first connection pipe 504, thus completing a cardiopulmonary resuscitation action; In the above process, the rise and fall of the second piston 507 both cause the force sensor 505 to generate a signal through the second spring 506, and the signal strength is related to the degree of rise and fall of the second piston 507. If the degree of fall is small, it indicates that the pressing depth is insufficient. If the fall depth is too large, it indicates that the pressing depth is too large. If the degree of rise is small, it indicates that the rebound degree is insufficient. If the degree of rise is appropriate, it indicates that the rebound degree is appropriate; In summary, after the entire training is completed, the data recorded by the force sensor 505 can illustrate the pressing frequency, number of times, the depth of each press, and the rebound distance, thus facilitating the trainee's summary.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
