Description

Technical Field

[0001] This utility model relates to the technical field of nursing practice devices, specifically to an arm nursing practice device. Background Technology

[0002] Venous puncture is a fundamental medical skill for practicing healthcare professionals. In clinical nursing demonstrations at schools or medical teaching institutions, venous puncture practice primarily involves learners performing punctures on each other. However, in the workplace, this is mainly achieved through puncturing patients. This approach increases patient discomfort and limits the number of practice sessions. Furthermore, discussing techniques in front of patients delays the time it takes for healthcare professionals to quickly master the skill.

[0003] The invention patent with authorization announcement number CN105632311B discloses an arm vein puncture model, including an arm model, a simulated blood vessel, a reservoir for storing simulated blood, and a turbine for providing power for the circulation of simulated blood; the reservoir is connected to the turbine, and the turbine is equipped with a stepless speed control switch; the arm model includes a simulated skin layer, a simulated subcutaneous tissue layer, and a muscle model arranged sequentially from the outside to the inside, and the surface of the muscle model has a groove for installing the simulated blood vessel; the simulated blood vessel part is located inside the arm model, and its inlet and outlet are connected to the outlet and inlet of the turbine, respectively.

[0004] In practical use, this invention uses simulated blood, which can easily leak and cause pollution after puncture. Furthermore, simulated blood needs to be added during practice, making it inconvenient for multiple people to practice for extended periods. Utility Model Content

[0005] The purpose of this invention is to provide an arm care practice device, which is mainly used to practice intravenous injection puncture. It can solve the technical problems in the prior art where the puncture easily causes leakage of simulated blood, resulting in pollution, and the need to add simulated blood during the practice process, which is not convenient for multiple people to practice for a long time.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] An arm care training device includes a simulated blood vessel assembly and a puncture assembly. The simulated blood vessel assembly includes a first air pump, a second air pump, a simulated blood vessel, a display, and a controller. The simulated blood vessel includes an inner layer and an outer layer, which are interconnected and form a cavity between them. The first air pump is connected to the cavity, the second air pump is connected to the inner layer, and the first air pump, the second air pump, and the display are connected to the controller.

[0008] The puncture assembly includes an injection needle body, a pressure detector, and a control board. The pressure detector is installed inside the injection needle body and connected to the control board, which is connected to a controller.

[0009] Furthermore, the inner layer is connected to a first pressure relief valve.

[0010] The puncture assembly also includes a battery, which is connected to a control board, and the control board is connected to a controller via a wireless signal.

[0011] Furthermore, the simulated blood vessel component also includes a human body model, with the simulated blood vessels pre-embedded inside the human body model according to the direction of human blood vessels.

[0012] Furthermore, the simulated blood vessel assembly also includes a turntable assembly, on which the human body model is mounted so that the human body model can rotate.

[0013] The turntable assembly includes a turntable and a base. The turntable is mounted on the base and rotates. The human model is mounted on the turntable. The first air pump, the second air pump, and the display are all mounted on the turntable.

[0014] Furthermore, a locking mechanism is provided between the turntable and the base.

[0015] Further optimization involves a locking assembly consisting of a spring and a locking ball. The turntable has mounting holes, and the base has several positioning holes arranged in a circumferential array. The spring is fixedly installed in the mounting holes, and the lower end of the spring is fixedly connected to the locking ball. Under the action of the spring, the locking ball engages with the positioning holes.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In practical use, this invention uses a first air pump to evacuate air from the cavity, reducing the internal air pressure, while a second air pump inflates the inner layer, increasing its pressure. During arm puncture practice, the injection needle is inserted into the simulated blood vessel. The puncture needle pierces both the outer and inner layers. During the puncture, the needle sequentially connects with the negative pressure cavity and the positive pressure environment of the inner layer, causing changes in the air pressure detected by the pressure gauge. Negative pressure indicates successful puncture of the outer layer, while positive pressure indicates successful puncture of the inner layer, achieving a normal puncture. This invention reflects the puncture result through changes in air pressure, as the simulated blood vessel... The tube is elastic, allowing the puncture needle to spring back and seal the puncture site after removal, preventing air leakage. Furthermore, the design uses inner and outer layers to create different regions within the simulated blood vessel: a hollow area near the vessel wall and a central area within the inner layer. When the puncture needle enters the central area, the puncture result is considered ideal. If the needle only enters the hollow area, the puncture depth and location are too close to the vessel wall, requiring more practice. Additionally, the puncture result can be reflected without adding simulated blood during the procedure, avoiding spillage and contamination, while also meeting the needs of multiple patients and extended practice sessions.

[0030] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0031] See Figures 1-3 This embodiment discloses an arm care practice device, specifically an arm puncture practice device, including a simulated blood vessel assembly and a puncture assembly. The simulated blood vessel assembly includes a first air pump 101, a second air pump 102, a simulated blood vessel 103, a display 104, and a controller. The simulated blood vessel 103 includes an inner layer 105 and an outer layer 106, which are interconnected, and a cavity 107 is formed between the inner layer 105 and the outer layer 106. The first air pump 101 is connected to the cavity 107, the second air pump 102 is connected to the inner layer 105, and the first air pump 101, the second air pump 102, and the display 104 are connected to the controller.

[0032] The puncture assembly includes an injection needle body 108, a pressure detector 109, and a control board 110. The pressure detector 109 is installed inside the injection needle body 108 and connected to the control board 110. The control board 110 is connected to a controller.

[0033] In practical use, this invention uses a first air pump 101 to evacuate air from the cavity 107, reducing the internal air pressure, while a second air pump 102 inflates the inner layer 105, increasing its pressure. During arm puncture practice, the injection needle body 108 is inserted into the simulated blood vessel 103. At this time, the puncture needle of the injection needle body 108 will pierce the outer layer 106 and the inner layer 105. During the puncture process, because the puncture needle sequentially connects with the negative pressure cavity 107 and the positive pressure environment of the inner layer 105, the air pressure detected by the pressure detector 109 changes. When the pressure is negative, it can be determined that the puncture has passed through the outer layer 106; when the pressure is positive, it can be determined that the puncture has entered the inner layer 105, achieving normal puncture. This invention uses changes in air pressure to... The simulated blood vessel 103 is elastic, allowing the needle to spring back and seal the puncture site after removal, preventing air leakage. Furthermore, the inner layer 105 and outer layer 106 create different regions within the simulated blood vessel 103: a cavity 107 region near the vessel wall and a central region of the inner layer 105. When the needle penetrates the central region, the puncture result is considered ideal. If the needle only enters the cavity 107 region, the puncture depth and location are too close to the vessel wall, requiring more practice. Additionally, the puncture result can be reflected without adding simulated blood during the procedure, avoiding spillage and contamination, while also meeting the needs of multiple patients and extended practice sessions.

[0034] In practical use, the inner layer 105 and the outer layer 106 are made of rubber or silicone materials with good elasticity.

[0035] The inner layer 105 and the outer layer 106 are connected at the lower side of the cross section to reduce the difficulty of fabricating the simulated blood vessel 103.

[0036] The inner layer 105 is connected to a first pressure relief valve, which enables a relatively stable air pressure to be formed inside the inner layer 105.

[0037] In actual use, the air pressure in the cavity and inner layer 105 is relatively small. When the puncture needle is inserted into the wall and the inner layer 105, the air pressure in the air pressure detector 109 should change. The specific air pressure value can be set according to actual needs.

[0038] The puncture assembly also includes a battery 111, which is connected to a control board 110. The control board 110 is connected to a controller via a wireless signal. This configuration allows the injection needle body 108 to be used independently, facilitating user operation and reducing the constraints of cables.

[0039] Furthermore, in some preferred embodiments, the simulated blood vessel component also includes a human body model 120, with the simulated blood vessels 103 pre-embedded inside the human body model 120 according to the direction of human blood vessels. This arrangement enables the present invention to have a higher similarity to the human body.

[0040] Furthermore, the simulated blood vessel assembly also includes a turntable assembly 112, on which the human body model 120 is mounted, enabling the human body model 120 to rotate. The human body model 120 has an internal skeleton and a surface covered with simulated rubber to mimic human structure.

[0041] The turntable assembly 112 includes a turntable 113 and a base 114. The turntable 113 is rotatably mounted on the base 114. The human model 120 is mounted on the turntable 113. The first air pump 101, the second air pump 102 and the display 104 are all mounted on the turntable 113.

[0042] In practical use, the position of the human body model 120 can be adjusted as needed to improve flexibility during practice.

[0043] A locking assembly 115 is provided between the turntable 113 and the base 114.

[0044] Furthermore, the locking assembly 115 includes a spring 116 and a locking ball 117. The turntable 113 has a mounting hole 118, and the base 114 has a plurality of positioning holes 119 arranged in a circumferential array. The spring 116 is fixedly installed in the mounting hole 118, and the lower end of the spring 116 is fixedly connected to the locking ball 117. Under the action of the spring 116, the locking ball 117 engages with the positioning hole 119. The locking assembly 115 enables positioning operations after the turntable 113 rotates.

[0045] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

It should be noted that any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
