[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1 to 8 As shown, the present invention provides an injection device for nursing operation training, including a mounting base 100, an injection device body 500 disposed inside the mounting base 100, an injection needle 600 inserted into the injection device body 500, and an injection needle cap 700 sleeved on the injection needle 600, and further including: The replacement mechanism 200 is located inside the injection device body 500; The reset mechanism 300 is located inside the injection device body 500; The fixing mechanism 400 is installed inside the mounting base 100; The replacement mechanism 200 includes a fixing groove 207 inside the injection device body 500, a fixing cylinder 201 fixedly installed inside the fixing groove 207, a fixing block 202 fixedly installed on the inner wall of the fixing groove 207, a first telescopic rod 203 fixedly installed on the fixing block 202, an insert block 204 fixedly installed on the movable end of the first telescopic rod 203, a first spring 205 sleeved on the side surface of the first telescopic rod 203, a sleeve 206 sleeved on the side surface of the injection device body 500, a control ring 208 slidably installed inside the fixing groove 207, a control rod 209 fixedly installed on the control ring 208, inclined grooves 211 on both sides of the insert block 204 for the control rod 209 to slide, a sliding groove 210 on the side surface of the injection device body 500 for the sleeve 206 to slide, and a slot 212 on the side surface of the injection needle 600 for the insert block 204 to be inserted into.

[0021] The plug 204 is slidingly installed inside the fixed cylinder 201 and penetrates the fixed cylinder 201, and the plug 204 is elastically connected with the fixed block 202 through the first spring 205, the inner wall of the sleeve 206 is fixedly connected with the control ring 208, and the injection needle 600 is inserted into the inside of the fixed cylinder 201.

[0022] With the above scheme: when the injection needle 600 needs to be replaced, the operator only needs to hold the sleeve 206 and then push away from the injection needle 600, so as to drive the control ring 208 to slide linearly along the sliding groove 210, and the control ring 208 also generates a corresponding displacement in the fixed groove 207, the control rod 209 fixedly connected with the control ring 208 is driven to move synchronously through the movement of the control ring 208, in the movement process of the control ring 208, the control rod 209 interacts with the inclined grooves 211 on both sides of the plug 204, so that the plug 204 is forced to overcome the elastic resistance of the first spring 205 and shrink into the inside space of the fixed cylinder 201, at this time, the mechanical connection between the old injection needle 600 and the fixed cylinder 201 is released, and the old needle can be pulled out of the fixed cylinder 201, then the operator takes a new injection needle 600 and aligns it with the opening of the fixed cylinder 201, when the new injection needle 600 is inserted, the front end thereof will first contact the inclined surfaces of the two plugs 204, under the action of the insertion force, the two plugs 204 will move to both sides at the same time and compress the first spring 205, as the injection needle 600 continues to penetrate, when the insertion slot 212 on the injection needle 600 is in the same horizontal position as the two plugs 204, the elastic potential energy stored in the first spring 205 is released, the plug 204 is accurately pushed into the inside space of the insertion slot 212, so as to realize reliable fixing of the new injection needle 600, the whole replacement process is designed ingeniously, and the operation steps are intuitive and clear, so that the replacement process is simplified and the efficiency during teaching demonstration and actual operation is improved.

[0023] As shown in Figure 1 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8 , the reset mechanism 300 comprises a lifting disc 301 sleeved on the side surface of the fixed cylinder 201 and movably connected with the fixed cylinder 201.

[0024] The side surface of the fixed cylinder 201 is sleeved with a second spring 302, and the lifting disc 301 is elastically connected with the top inner wall of the fixed groove 207 through the second spring 302.

[0025] The top of the control ring 208 is fixedly connected with a top rod 303, and the top of the top rod 303 is attached to the bottom of the lifting disc 301.

[0026] With the above scheme: during the operation of replacing the injection needle 600, the sleeve 206 needs to be pushed steadily away from the end of the injection needle 600 along the axial direction of the fixed cylinder 201, which will drive the top rod 303 fixedly connected thereto to produce synchronous displacement, the movement of the top rod 303 will directly act on the lifting disc 301 to make it slide steadily upward along the side surface of the fixed cylinder 201, in the process, the second spring 302 installed below the lifting disc 301 will be gradually compressed to produce corresponding elastic deformation, ensuring that the injection needle 600 can smoothly perform subsequent operation processes, or be safely pulled out from the inside of the fixed cylinder 201 for replacement and maintenance, when the operator releases the pushing force on the sleeve 206, the compressed second spring 302 will release the elastic potential energy stored therein, and the restoring force will drive the lifting disc 301 to move downward to return to the initial position, at the same time, the series of components such as the top rod 303, the control ring 208 and the control rod 209 linked with the lifting disc 301 will also be reset under the action of the spring force, returning to the original state before operation, fully preparing for subsequent use, ensuring that the injection device can work stably in a cycle.

[0027] As shown in Figure 1 and Figure 2 The fixing mechanism 400 includes a mounting groove 401 opened in the inside of the mounting seat 100, the injection device body 500 is arranged inside the mounting groove 401, and limit grooves 402 are opened in the inner walls of the two sides of the mounting groove 401.

[0028] The inside of the limit groove 402 is slidably connected with a moving plate 403, and the opposite side of each of the two moving plates 403 is fixedly connected with a clamping block 404 matched with the injection device body 500.

[0029] A second telescopic rod 405 is fixedly connected to the inner wall of one side of the limit groove 402, and the movable end of the second telescopic rod 405 is fixedly connected to the end of the moving plate 403 away from the clamping block 404.

[0030] The side surface of the second telescopic rod 405 is sleeved with a third spring 406, the moving plate 403 is elastically connected to the inner wall of one side of the limit groove 402 through the third spring 406, and the inside of the limit groove 402 is slidably connected with a sliding rod 407.

[0031] The sliding rod 407 penetrates through the limit groove 402 and is movably connected with the limit groove 402, one end of the sliding rod 407 is fixedly connected to one side of the moving plate 403, and the end of the sliding rod 407 away from the moving plate 403 is fixedly connected with a pull block 408.

[0032] When the injection device body 500 needs to be taken out for teaching use, the user can manually pull the pull block 408, the movement of the pull block 408 drives the sliding rod 407 connected thereto to slide along the limiting groove 402, the sliding action of the sliding rod 407 further drives the movement plate 403 to accurately linearly displace in the limiting groove 402, in this process, the second telescopic rod 405 is shortened under the action of the compression force, and the third spring 406 is also compressed and stores elastic potential energy, the two symmetrically arranged movement plates 403 simultaneously move in opposite directions, the relative movement releases the clamping connection between the clamping block 404 fixed on the movement plate 403 and the injection device body 500, so that the injection device body 500 can be smoothly taken out from the mounting groove 401, and the related operation training or maintenance work is facilitated.

[0033] The working principle and use process of the present application are as follows: When the injection device body 500 needs to be taken out for teaching use, the user can manually pull the pull block 408, the movement of the pull block 408 drives the sliding rod 407 connected thereto to slide along the limiting groove 402, the sliding action of the sliding rod 407 further drives the movement plate 403 to accurately linearly displace in the limiting groove 402, in this process, the second telescopic rod 405 is shortened under the action of the compression force, and the third spring 406 is also compressed and stores elastic potential energy, the two symmetrically arranged movement plates 403 simultaneously move in opposite directions, the relative movement releases the clamping connection between the clamping block 404 fixed on the movement plate 403 and the injection device body 500, so that the injection device body 500 can be smoothly taken out from the mounting groove 401, and the related operation training or maintenance work is facilitated.

[0034] When the training or maintenance work is completed, the injection device body 500 needs to be reinstalled on the mounting seat 100, just align the injection device body 500 with the opening position between the two clamping blocks 404, and then apply a vertical downward pressing force, which will make the side wall of the injection device body 500 in contact with the inclined surface of the clamping block 404, generating a horizontal component force to push the two clamping blocks 404 apart, and as the continuous downward pressing, the clamping block 404 will continue to move outward until the injection device body 500 is completely in the predetermined position of the mounting groove 401, at this time, the compressed third spring 406 will release the stored elastic potential energy, generating a reverse force to push the moving plate 403 to move inwardly, driving the clamping block 404 to re-clamp the fixed part of the injection device body 500, ensuring that the injection device body 500 can be firmly fixed in the mounting groove 401, maintaining a stable working state, providing reliable protection for subsequent reuse, the whole installation and fixing process is simple and easy to operate, and the fixing effect is stable and reliable. Through the setting of the injection needle cap 700, the injection needle 600 can be protected.

[0035] When the injection needle 600 needs to be replaced, just push the sleeve 206 away from the injection needle 600, thereby driving the control ring 208 to move in the fixed groove 207, and then driving the control rod 209 to move upward synchronously, and then making the insertion block 204 overcome the elastic force of the first spring 205 to shrink into the fixed cylinder 201, at this time, the old injection needle 600 can be pulled out from the fixed cylinder 201, the elastic potential energy of the second spring 302 will push the lifting disc 301 to reset downwardly, and at the same time, drive the top rod 303, the control ring 208 and the control rod 209 and other components to restore to the initial state, preparing for the next operation, and then inserting the new injection needle 600 into the fixed cylinder 201, the inclined surface of which will press the two insertion blocks 204 to move to both sides, and at the same time, compress the first spring 205, when the insertion slot 212 and the two insertion blocks 204 are in the same horizontal line, the elastic potential energy of the first spring 205 will push the insertion block 204 into the insertion slot 212, completing the replacement of the injection needle 600, the whole device is simple and easy to operate, improving the teaching and replacement efficiency, and being suitable for nursing operation training.
