Description

Technical Field

[0001] The utility model relates to the field of simulating the chest undulation of the human body, in particular to a simulation teaching model for simulating the chest undulation. Background Art

[0002] During the medical teaching process, intubation operation is one of the teaching focuses and more importantly, the teaching difficulty. Intubation operation usually refers to inserting a special pipeline or catheter into the body through the body surface and internal cavities of the human body to achieve the purpose of medical examination, treatment or other needs. Among them, the operation of intubating through the oral cavity or nasal cavity has relatively high requirements for medical staff. It requires not only familiarity with human anatomy, but also proficient operation skills, and cannot be operated and repeatedly practiced on patients. During the training in the medical teaching stage, specific human models are often used for operation training. The chest undulation model in the human model is an important part of the human model. During the teaching of oral intubation, it is necessary to simulate the chest undulation caused by normal breathing of the human chest and the physiological reactions in various scenarios during the intubation process. The simulation of the human chest undulation has become a key link in teaching, directly affecting the quality and effect of intubation teaching. The existing human model technology does not have a corresponding chest undulation model and cannot achieve the best intubation teaching effect. To solve this teaching difficulty, a human chest undulation simulation teaching model is provided, which can more realistically simulate the intubation scenarios through the oral cavity or nasal cavity, shorten the training time and improve the operation technology.

[0021] Embodiment

[0022] As Figures 1 to 3 shown, a simulation teaching model for simulating chest undulation includes a chest simulation model 201. The surface of the chest simulation model 201 has a chest pressing undulating part 2011. Inside the chest simulation model 201, there is a pressing undulating component corresponding to the chest pressing undulating part 2011. The pressing undulating component includes a support base 204, a limit sleeve 203, and a lifting undulating rod 202. At least one limit sleeve 203 is installed on the support base 204, and a lifting undulating rod 202 is installed for lifting and lowering in each limit sleeve 203. The top of the lifting undulating rod 202 correspondingly abuts against the chest pressing undulating part 2011. A servo motor 210 for repeated lifting and lowering movement is further provided between the chest pressing undulating part 2011 and the support base 204. The servo motor 210 of the present utility model realizes the repeated lifting and lowering operation, providing power for the undulating movement of the chest pressing undulating part 2011. The present utility model may also not include the servo motor 210 (in this case, a return spring needs to be added), and medical personnel can train the artificial chest pressing first aid operation. Preferably, a pressing sensor is provided on the chest pressing undulating part 2011. Under the lifting drive of the servo motor 210 (because the chest undulating movement is not large, the lifting arc of the servo motor 210 is not large, and the lifting frequency of the servo motor 210 can be set, such as setting the undulating frequency of a normal person or the undulating frequency of a certain patient; since the lifting arc of the servo motor 210 is not large, the present utility model can use only one lifting undulating rod 202 and a matching limit sleeve 203 to realize the chest undulating operation), the lifting undulating rod 202 moves up and down in the limit sleeve 203, thereby driving the chest pressing undulating part 2011 to move up and down, simulating the chest undulating movement of the human body, making the medical teaching more realistic.

[0023] In some embodiments, Figure 1 As shown, the surface of the chest simulation model 201 also has an ups and downs auxiliary part 2012 (simulating the position of the human abdomen, generally moving synchronously with the chest), and the chest simulation model 201 has an ups and downs auxiliary component corresponding to the ups and downs auxiliary part 2012 inside. The ups and downs auxiliary component includes a telescopic airbag tube 208 (simulating the inhalation and exhalation of the human body, the utility model is a part of the applicant's human medical model, and only the chest ups and downs operation is recorded in the technology of this application. The telescopic airbag tube 208 simulates the inhalation and exhalation operation of the heart, and there is a corresponding trachea connection in other technical patents), and a driving plate arranged at the bottom of the telescopic airbag tube 208 and driving the telescopic airbag tube 208 to contract. Figure 3 As shown, when the driving plate moves upward, it will drive the telescopic airbag tube 208 to contract, thereby compressing the telescopic airbag tube 208; when the driving plate moves downward, it will drive the telescopic airbag tube 208 to increase its volume and return to its original state. The telescopic airbag tube 208 is connected to an air inlet pipe 2081 and an air outlet pipe 2082 (there are corresponding air pipe connections in other technical patents. The air inlet pipe 2081 and the air outlet pipe 2082 of the utility model only correspond to each other to realize the telescopic operation of the telescopic airbag tube 208. When the volume of the telescopic airbag tube 208 increases, the air inlet pipe 2081 takes in air, and when the volume of the telescopic airbag tube 208 decreases, the air outlet pipe 2082 exhausts air). The bottom end of the lifting and undulating rod 202 passes through the limiting sleeve 203, and a multi-link module 206 is connected between the bottom end of the lifting and undulating rod 202 and the driving plate at the bottom of the telescopic airbag tube 208 (see Figure 3 ), the middle part of the multi-link module 206 is rotatably hinged on the support seat 204 through the rotating pin 205, so that the lifting and lowering movement of the lifting and lowering rod 202 is synchronously transmitted to the driving plate through the multi-link module 206, and the telescopic movement of the telescopic airbag tube 208 is realized through linkage.

[0024] In some embodiments, the undulation auxiliary portion 2012 is made of silicone material, and the cavity shell portion of the chest simulation model 201 can also be made of silicone material.

[0025] In some embodiments, although the above description is an implementation description of a lifting and undulating rod 202 and a limiting sleeve 203, a further preferred technical solution is as follows: limiting sleeves 203 are respectively provided on both sides of the support seat 204, and the top ends of the two lifting and undulating rods 202 jointly support the bottom of the chest pressing undulating part 2011, and the two lifting and undulating rods 202 are respectively linked to the two sides of the driving plate at the bottom of the telescopic airbag tube 208 through the multi-link module 206.

[0026] like Figure 2 , Figure 3As shown, a top seat 209 is further provided at the top of the telescopic airbag cylinder 208 (the top seat 209 is located inside the undulating auxiliary part 2012), and a base 207 is correspondingly provided at the bottom of the telescopic airbag cylinder 208. The base 207 can be integrated with the support seat 204.

[0027] As Figure 3 shown, the multi-link module 206 includes a linkage main rod, a first link and a second link movably hinged to both ends of the linkage main rod. The multi-link module 206 is composed of three parts: the linkage main rod, the first link and the second link. The middle of the linkage main rod is hinged to the support seat 204 through a rotating pin 205. The end of the first link and the end of the second link are respectively hinged to both ends of the linkage main rod. The end of the first link is movably hinged to the bottom end of the lifting undulating rod 202, and the end of the second link is movably hinged to the driving plate at the bottom of the telescopic airbag cylinder 208. When the lifting undulating rod 202 moves downward, the end of the first link descends and drives the constrained end of the linkage main rod ( Figure 3 the left end) to descend correspondingly. In this way, the other end of the linkage main rod ( Figure 3 the right end) rises correspondingly, thereby driving the second link to move and driving the driving plate to compress the telescopic airbag cylinder 208. When the lifting undulating rod 202 moves upward, the end of the first link rises and drives the constrained end of the linkage main rod ( Figure 3 the left end) to rise correspondingly. In this way, the other end of the linkage main rod ( Figure 3 the right end) descends correspondingly, thereby driving the second link to move and driving the driving plate to move downward, and the telescopic airbag cylinder 208 increases in volume and resets.

[0028] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
