Description

Technical Field

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

[0002] Cardiopulmonary resuscitation is a life-saving technique for the heart and breathing that have stopped, aiming to restore the patient's spontaneous breathing and 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 everyone has different body postures, different forces are required to achieve the same depth. 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, the compression mechanisms in most 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 stretching 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 feel different forces, but the actual depth may already be sufficient or excessive.

[0004] In addition, most cardiopulmonary resuscitation training devices use electronic devices such as sensors and controllers to reflect the compression depth situation in real time using numbers, 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.

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 situations.

[0082] The following is 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:

[0083] A base 1, on the top of the base 1, a leather sleeve 201 is fixed, and on the inner wall of the top of the leather sleeve 201, a plate body 807 is fixed;

[0084] A metal box 202, which is fixed inside the leather sleeve 201;

[0085] Two adjusting components, both of which are fixed on the top of the metal box 202, and both adjusting components are fixed to the plate body 807;

[0086] Two buffer components, both of which are fixed to the base 1;

[0087] A display component, which is communicated with the two buffer components;

[0088] A storage component, which is communicated with the display component and the two buffer components, and both adjusting components are communicated with the storage component;

[0089] Among them, the adjusting component includes:

[0090] A sleeve 801, which is fixed on the top of the metal box 202, and a third piston 808 is slidably arranged inside the sleeve 801;

[0091] A sleeve rod 802, which is fixed to the third piston 808 and is fixed to the plate body 807;

[0092] A communication component, which is fixed to the sleeve 801 and 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;

[0093] An impact component, which is arranged at the bottom of the sleeve 801 and is connected to the third piston 808.

[0094] By means of the function of the connected components in cooperation with a vacuum pump, the air pressure above the third piston 808 in the sleeve 801 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 session of this device, the required force can be appropriately adjusted to strengthen the sense of distance of the training pressing depth, so as to ensure the quality of cardiopulmonary resuscitation actions;

[0095] 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.

[0096] Furthermore, it also includes:

[0097] The first pipe body 803, the first pipe body 803 is connected to the two sleeves 801, and the first pipe body 803 is above the two third pistons 808;

[0098] The second pipe body 804, the second pipe body 804 is connected to the two sleeves 801, and the second pipe body 804 is below the two third pistons 808.

[0099] Furthermore, the impact component includes:

[0100] The connecting rod 810, the connecting rod 810 is fixed to the bottom of the sleeve 801;

[0101] 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;

[0102] The cross groove 813, the cross groove 813 is provided on the top of the connecting rod 810;

[0103] The transmission rod 814, the transmission rod 814 is slidably arranged in the cross groove 813;

[0104] 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;

[0105] Two connecting rods 816, both of the two connecting rods 816 are rotatably connected to the transmission rod 814;

[0106] 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, and the limiting blocks 815 are adapted to the limiting grooves;

[0107] 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;

[0108] The third spring 809 is fixed to the third piston 808 and is fixed to the inner wall of the bottom of the sleeve 801.

[0109] 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. Thereafter, 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 to this extent will cause the patient's chest to fracture and other situations.

[0110] Furthermore, the connecting component includes:

[0111] The air extraction pipe 301 is connected to one of the sleeves 801 and is located above the third piston 808;

[0112] The first one-way valve 302 is connected to the air extraction pipe 301, and the air extraction pipe 301 penetrates through the leather sleeve 201;

[0113] The plug 303 is arranged at the end of the air extraction pipe 301.

[0114] 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.

[0115] Furthermore, the buffer component includes:

[0116] The fixing plate 401 is fixed to the base 1;

[0117] The buffer pipe 402 is fixed to the top of the fixing plate 401;

[0118] The third one-way valve 405 is arranged through the top of the buffer pipe 402;

[0119] The second one-way valve 403 is arranged through the top of the side wall of the buffer pipe 402;

[0120] The first piston 406 is slidably arranged in the buffer pipe 402;

[0121] The first spring 407 is fixed inside the buffer tube 402, and the first spring 407 is fixed to the first piston 406.

[0122] Due to 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;

[0123] Furthermore, the storage assembly includes:

[0124] A storage tube 601, with a second connecting tube 602 provided at the top of the storage tube 601;

[0125] A filter screen 603, fixed inside the storage tube 601;

[0126] A connecting pipe 404, communicating with two second one-way valves 403, and the end of the connecting pipe 404 penetrates through the top of the filter screen 603.

[0127] When the plate body 807 descends, two third pistons 808 are pushed to move downward by two sleeve rods 802. With the cooperation of the second tube body 804, during the descent of the third piston 808, the gas below the third piston 808 in the two sleeves 801 is introduced into the connection tank 501 through the air delivery pipe 502, and the second piston 507 is pushed to descend.

[0128] Furthermore, the storage assembly further includes:

[0129] A support plate 503, fixed to the storage tube 601;

[0130] A connection tank 501, fixed on the support plate 503;

[0131] A first connecting pipe 504, one end of which penetrates through the bottom of the connection tank 501, and the first connecting pipe 504 penetrates through the bottom side wall of the storage tube 601;

[0132] A second piston 507, slidably arranged inside the connection tank 501;

[0133] A force sensor 505, fixed on the inner wall of the top of the connection tank 501;

[0134] A second spring 506, one end of which is fixed to the force sensor 505, and the other end of the second spring 506 is fixed to the second piston 507;

[0135] The gas transmission pipe 502 is disposed through the side wall of the connection tank 501, and the gas transmission pipe 502 is located above the second piston 507. The gas transmission pipe 502 penetrates the bottom of the side wall of one of the sleeves 801.

[0136] During cardiopulmonary resuscitation, when pressing, the third piston 808 descends, and the gas in the sleeve 801 will be injected into the connection tank 501 through the gas transmission pipe 502, and the second piston 507 is pushed to descend, so as to inject the liquid below the second piston 507 in the connection tank 501 into the storage pipe 601 through the support plate 503;

[0137] 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. Therefore, 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.

[0138] Furthermore, the display component includes:

[0139] The semi-circular seat 701 is communicated with two third one-way valves 405. An installation hole is opened at the top of the semi-circular seat 701, and the second connecting pipe 602 is disposed through the inner wall of the bottom of the semi-circular seat 701;

[0140] The transparent plate 702 is fixed in the installation hole.

[0141] Through the transparent plate 702, it is convenient to observe the situation in the semi-circular seat 701.

[0142] Furthermore, the storage pipe 601, the semi-circular seat 701, 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.

[0143] When the liquid flows through the filter screen 603, it will carry the glitter on the filter screen 603 and enter the semi-circular 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 semi-circular seat 701 during pressing, so as to increase the trainee's deeper understanding of the significance of cardiopulmonary resuscitation training.

[0144] Furthermore, it further includes:

[0145] The bracket 805 is fixed on the top of the metal box 202;

[0146] Two support rods 806 are both slidably connected to the bracket 805, and both of the two support rods 806 are fixed to the plate body 807.

[0147] The specific working method is as follows: When in use, first connect the vacuum pump to the first one-way valve 302, and extract the gas in the air extraction 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 downward, so as to adjust the force required for cardiopulmonary resuscitation and simulate patients with different physiques;

[0148] During the training action of cardiopulmonary resuscitation, when pressing, the root of the trainee's palm should be in contact with the top of the leather sleeve 201 and press downward to push the plate body 807 downward;

[0149] 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 enters the connection tank 501 through the air delivery pipe 502, and the second piston 507 is pushed downward;

[0150] When the second piston 507 descends, the liquid below the second piston 507 in the connection tank 501 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;

[0151] When the pressing depth is relatively low, less liquid enters the semi-circular seat 701 through the second connection pipe 602, and thus the overall amount of glitter carried is less, indicating that this degree of cardiopulmonary resuscitation will result in insufficient pump blood volume, and thus the pressing depth needs to be increased. On the contrary, 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;

[0152] 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 downward, while compressing the fourth spring 812. The downward movement of the transmission rod 814 drives the two brackets 805 to approach each other through the two connecting rods 816, so that the bracket 805 leaves 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. The cooperation with the metal box 202 at the bottom of the sleeve 801 produces a sound, indicating that this degree of cardiopulmonary resuscitation will cause the patient's chest fracture and other situations;

[0153] Due to 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 down. During this process, the liquid carries the glitter powder into the buffer tube 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 acting 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 synchronously reset by 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 passes the liquid and glitter powder in the buffer tube 402 into the storage tube 601 through the second one-way valve 403 and the connecting tube 404, and enters the position above the filter screen 603. Through the filtration of the filter screen 603, the glitter powder is left on the filter screen 603, while the liquid returns to the connection tank 501 through the first connecting tube 504, thus completing a cardiopulmonary resuscitation action;

[0154] During the above process, the rise and fall of the second piston 507 both cause the force sensor 505 to generate signals through the second spring 506, and the signal intensity is related to the rise and fall degree of the second piston 507. If the fall degree 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 rise degree is small, it indicates that the rebound degree is insufficient. If the rise degree is appropriate, it indicates that the rebound degree is appropriate;

[0155] In summary, after the entire training, 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 summary by the trainee.

[0156] 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 it; 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 make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
