Description

Technical Field

[0001] The utility model relates to the technical field of medical training equipment, in particular to a medical puncture teaching operation training device. Background Art

[0002] Medical puncture is an important clinical operation skill, covering various types, such as venipuncture, arterial puncture, thoracentesis, abdominal puncture, etc. These puncture operations play a key role in diagnosis, treatment and monitoring of patient conditions.

[0003] During instructional training, trainees need to learn and master the basic principles of puncture, including anatomical knowledge, operational procedures, techniques, and precautions. Through standardized training, trainees can reduce errors in actual operations and reduce patient pain and risk. Secondly, good puncture skills can help improve the efficiency of medical work, such as quickly establishing intravenous access for infusion, medication, and other treatment operations, and promptly obtaining patient body fluid samples for testing and diagnosis. Furthermore, skilled puncture operations can enhance patients' trust in medical personnel, improve their medical experience, and play a positive role in building a harmonious doctor-patient relationship.

[0004] However, in actual puncture operations, the flow of blood will produce a certain amount of resistance and pressure feedback on the puncture needle, and existing simulation devices cannot truly simulate this dynamic mechanical feeling. When trainees use these devices for training, the feeling after the puncture needle enters the "blood vessel" is quite different from the actual situation, and it is difficult to accurately grasp the force and depth of the needle insertion. Based on the above viewpoints, technical personnel in this field have proposed a medical puncture teaching operation training device. Utility Model Content

[0005] The purpose of the present utility model is to solve the shortcomings of the existing technology and propose a medical puncture teaching and operation training device. The medical puncture teaching and operation training device designed uses a micro pump to suck artificial blood stored in a storage tube, and injects the sucked artificial blood into a quick-detachable simulation liner through a delivery tube and flows back into the storage tube through a delivery tube, thereby simulating the flow state of blood in the blood vessels. When performing puncture operation training, students can feel resistance similar to that of a real human body, allowing students to better understand the force control of needle insertion under blood flow.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] The utility model provides a kind of medical puncture teaching operation training device, including micro pump, the input end of the micro pump is connected with storage cylinder, the other end of the storage cylinder and the output of the micro pump are connected with delivery pipe, the outside wall of the micro pump and storage cylinder is connected with placing rack, the upper side wall middle position of the placing rack is fixedly connected with mounting bracket, the left and right sides of the mounting bracket are all provided with pipeline interface, the inner side wall of two the pipeline interface is all connected with elastic member, the other end of two the delivery pipe is fixed in two pipeline interface respectively by the elastic member in two pipeline interface, the center of the mounting bracket is clamped with quick-release type simulation inner container.

[0008] Through the above technical scheme, the device pumps the artificial blood stored in the storage cylinder by micro pump, and injects the pumped artificial blood into quick-release type simulation inner container through delivery pipe and returns to the storage cylinder through a delivery pipe, to simulate the flow state of blood in blood vessels, so that students can feel similar resistance to real human body when practicing puncture operation, and better understand the force control of needle insertion under blood flow.

[0009] Further, a control panel is installed on the front side wall of the placing rack, and the control panel is electrically connected with the micro pump.

[0010] Through the above technical scheme, the pumping speed of the micro pump for the artificial blood stored in the storage cylinder is controlled through the control panel, to adjust the circulation speed of blood and realize the simulation of blood circulation at multiple rates.

[0011] Further, the quick-release type simulation inner container includes a simulation leather sheath, and elastic plugs are fixedly connected to the inner side walls of the simulation leather sheath.

[0012] Through the above technical scheme, the quick-release type simulation blood vessel is fixed in the simulation leather sheath by two elastic plugs, and the simulation leather sheath is fixed by friction with the inner wall of the mounting bracket, so that the quick-release type simulation inner container can be quickly and conveniently taken out of the mounting bracket, and when the student finishes puncture, the quick-release type simulation blood vessel can be taken out of the elastic plug for replacement, which is very convenient.

[0013] Further, springs are connected to spring sealing plates near the delivery pipe on the inner side wall of the mounting bracket.

[0014] Through the above technical scheme, when the quick-release type simulation inner container is taken out, the two spring sealing plates are lifted upward due to the loss of extrusion of the quick-release type simulation inner container, to seal the two pipeline interfaces, to prevent artificial blood from flowing out when the quick-release type simulation inner container is taken out.

[0015] Furthermore, a fixing frame is fixedly connected to the lower inner wall of the simulated leather case and located between the simulated leather case and the quick-detachable simulated blood vessel, and an adjustable puncture needle limiting frame is limitedly and slidably connected between the fixing frame and the simulated leather case;

[0016] Through the above technical solution, by adjusting the adjustable puncture needle limit frame to make it slide on the fixed frame, the exposure position of the quick-detachable simulated blood vessel can be adjusted, thereby realizing the simulation of the blood vessel puncture angle.

[0017] The utility model has the following beneficial effects:

[0018] 1. In this utility model, a micropump is used to draw artificial blood from a storage tube, which is then injected into a quick-detachable simulation liner through a delivery tube and then flows back into the storage tube through a delivery tube, thereby simulating the flow of blood in blood vessels. This allows trainees to feel resistance similar to that of a real human body during puncture training, allowing them to better understand the force control of needle insertion under blood flow.

[0019] 2. In the present invention, the simulated leather case is fixed by the friction between it and the inner wall of the mounting frame, so that the quick-detachable simulated liner can be quickly and conveniently removed from the mounting frame. At the same time, when the trainee completes the puncture, the quick-detachable simulated blood vessel can be removed from the elastic plug and replaced, which is very convenient.

[0020] 3. In the present invention, by adjusting the adjustable puncture needle limit frame to make it slide on the fixed frame, the exposed position of the quick-detachable simulated blood vessel can be adjusted, thereby achieving the simulation of the blood vessel puncture angle.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example: Refer to Figure 1-4 The present invention provides an embodiment of a medical puncture teaching and operation training device, comprising a micro pump 6, the input end of the micro pump 6 is connected to a storage cylinder 7, the other end of the storage cylinder 7 and the output end of the micro pump 6 are connected to a delivery tube 4, the outer wall of the micro pump 6 and the storage cylinder 7 are connected to a display rack 1, the middle position of the upper side wall of the display rack 1 is fixedly connected to a mounting rack 2, the left and right sides of the mounting rack 2 are provided with pipeline interfaces 9, the inner side walls of the two pipeline interfaces 9 are connected to elastic members, the other ends of the two delivery tubes 4 rely on two pipelines The elastic member in the interface 9 is fixed in the two pipe interfaces 9, and a quick-detachable simulation liner 3 is clamped at the center of the mounting frame 2. The device sucks the artificial blood stored in the storage tube 7 through the micro pump 6, and injects the sucked artificial blood into the quick-detachable simulation liner 3 through the delivery tube 4 and flows back into the storage tube 7 through a delivery tube 4, thereby simulating the flow state of blood in the blood vessels, so that trainees can feel the resistance similar to that of the real human body when performing puncture operation training, allowing trainees to better understand the force control of needle insertion in the presence of blood flow.

[0030] In an optional embodiment, a control panel 5 is mounted on the front sidewall of the display rack 1 and is electrically connected to a micropump 6. The control panel 5 controls the pumping speed of the artificial blood stored in the cylinder 7 by the micropump 6, thereby adjusting the blood circulation speed and simulating real-world blood circulation at various rates.

[0031] In an optional embodiment, the quick-detachable simulated liner 3 includes a simulated leather case 31, with elastic plugs 34 fixedly connected to the inner side walls of the simulated leather case 31. A quick-detachable simulated blood vessel 35 is mounted within the two elastic plugs 34. The quick-detachable simulated blood vessel 35 is secured within the simulated leather case 31 by the two elastic plugs 34, while the simulated leather case 31 is secured by friction with the inner wall of the mounting frame 2. This allows the quick-detachable simulated liner 3 to be quickly and easily removed from the mounting frame 2. Once the trainee completes the puncture, the quick-detachable simulated blood vessel 35 can be removed from the elastic plugs 34 for easy replacement, providing a very convenient experience.

[0032] In an optional embodiment, a spring-loaded sealing plate 8 is connected to the inner sidewall of the mounting frame 2 near the delivery tube 4 via a spring. When the quick-release simulated liner 3 is removed, the two spring-loaded sealing plates 8 lift upward due to the loss of the pressure from the quick-release simulated liner 3, thereby sealing the two pipe interfaces 9 and preventing the artificial blood from flowing out when the quick-release simulated liner 3 is removed.

[0033] In an optional embodiment: a fixing frame 32 is fixedly connected to the lower inner wall of the simulated leather case 31 and located between the simulated leather case 31 and the quick-detachable simulated blood vessel 35, and an adjustable puncture needle limiting frame 33 is slidingly connected between the fixing frame 32 and the simulated leather case 31. By adjusting the adjustable puncture needle limiting frame 33 to make it slide on the fixing frame 32, the exposed position of the quick-detachable simulated blood vessel 35 can be adjusted, thereby realizing the simulation of the blood vessel puncture angle.

[0034] Working principle: The device uses a micro pump 6 to suck the artificial blood stored in the storage tube 7, and injects the sucked artificial blood into the quick-detachable simulation liner 3 through a delivery tube 4 and flows back into the storage tube 7 through a delivery tube 4, thereby simulating the flow state of blood in the blood vessels, so that trainees can feel the resistance similar to that of the real human body when performing puncture operations, allowing trainees to better understand the force control of needle insertion under blood flow conditions. The control panel 5 controls the suction speed of the micro pump 6 for the artificial blood stored in the storage tube 7, thereby adjusting the blood circulation speed, and realizing the simulation of blood circulation at multiple rates. The simulation leather case 31 relies on its installation The friction force of the inner wall of the frame 2 achieves fixation, so that the quick-detachable simulated liner 3 can be quickly and conveniently removed from the mounting frame 2. At the same time, when the trainee completes the puncture, the quick-detachable simulated blood vessel 35 can be removed from the elastic plug 34 and replaced, which is very convenient. When the quick-detachable simulated liner 3 is removed, the two spring sealing plates 8 lose the squeezing of the quick-detachable simulated liner 3, causing it to lift up, and then close the two pipe interfaces 9 to prevent artificial blood from flowing out when the quick-detachable simulated liner 3 is removed. By adjusting the adjustable puncture needle limit frame 33 to make it slide on the fixing frame 32, the exposed position of the quick-detachable simulated blood vessel 35 can be adjusted, thereby realizing the simulation of the blood vessel puncture angle.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
