The pressure induction switch is arranged corresponding to the needle-piercing tube and is on the same horizontal line. The pressure induction switch is electrically connected to a pressure controller, and the pressure controller is electrically connected to the electric valve.
[0006] Furthermore, the simulation teaching target is made of silica gel material, and both the simulation teaching target and the leather tube are transparent.
[0007] Furthermore, a liquid adding tube is fixedly arranged on one side at the top of the sealed liquid storage box, and a liquid adding tube cover body is threadedly arranged at the top of the liquid adding tube.
[0008] Furthermore, a leather tube sleeve is fixedly arranged through the bottom of the simulation teaching fixing seat. The leather tube passes through the leather tube sleeve, and the leather tube is fixedly connected to the leather tube sleeve.
[0009] Further, the non-invasive needle mechanism includes a hand-held block. A rope-passing hole is longitudinally formed at the top of the hand-held block. A connecting rope is fixedly arranged on the outer wall of the upper end of the simulation teaching target. The connecting rope passes through the rope-passing hole and extends downward. A limiting ball is fixedly arranged at the bottom end of the connecting rope, and the limiting ball is in limiting cooperation with the bottom end of the rope-passing hole.
[0010] Further, the non-invasive needle mechanism further includes an installation vertical block. The installation vertical block is fixedly connected to the hand-held block.

[0027] Please refer to Figures 1-5 , an infusion port teaching trainer, comprising a simulation teaching target 9 and a non-invasive needle mechanism. The simulation teaching target 9 is made of silicone material and is transparent, facilitating the observation of the internal structure and state. Inside the simulation teaching target 9, a simulation teaching fixing seat 10 is fixedly arranged. The inside of the simulation teaching fixing seat 10 is hollow. On one side inside the simulation teaching fixing seat 10, a sealed liquid storage box 15 is fixedly arranged. Inside the sealed liquid storage box 15, a detection liquid 16 is arranged. The detection liquid 16 is ordinary red water liquid, used to simulate blood after needle puncture. On the outer wall of the simulation teaching fixing seat 10, a needle-passing tube 11 is fixedly arranged. At the bottom of the sealed liquid storage box 15, a flowing water hole 17 is opened. An electric valve 21 is fixedly arranged in the flowing water hole 17. When the electric valve 21 is opened, the detection liquid 16 in the sealed liquid storage box 15 can flow out through the flowing water hole 17.
[0028] At the bottom of the sealed liquid storage box 15, an intermediate hopper tube 1 is fixedly arranged. At the bottom of the intermediate hopper tube 1, a leather tube 13 is fixedly arranged. The liquid flowing out from the flowing water hole 17 flows out through the leather tube 13. The leather tubes 13 are all transparent, facilitating the observation of the liquid flow inside. The bottom end of the leather tube 13 penetrates through the simulation teaching fixing seat 10 and extends downward. On the outer wall of the sealed liquid storage box 15, a pressure induction switch 18 is fixedly arranged. The pressure induction switch 18 is arranged corresponding to the needle-passing tube 11 and is on the same horizontal line. The pressure induction switch 18 is electrically connected to a pressure controller. The pressure controller is used to collect the electrical signal of the pressure induction switch 18. The pressure controller is electrically connected to the electric valve 21 and is used to control the opening of the electric valve 21 when the pressure induction switch 18 detects a pressure signal. Among them, the pressure induction switch 18, the pressure controller and the electric valve 21 are all components purchased on the market. The pressure controller controls the opening and closing of the electric valve 21 by sending an electrical signal command, and its control principle belongs to conventional technology and will not be elaborated.
[0029] During operation, hold the holding block 5 and drive the non-invasive needle 8 to insert into the needle-passing tube 11. When the non-invasive needle 8 is successfully punctured, the non-invasive needle 8 just touches the pressure induction switch 18. The pressure induction switch 18 senses the pressure and transmits the pressure signal to the pressure controller. The pressure controller controls the opening of the electric valve 21. At this time, it can be seen that red water liquid flows into the leather tube 13, indicating successful puncture. On the contrary, if no red water liquid comes out, it indicates unsuccessful puncture.
[0030] As an improvement of the above technical solution, a leather tube sleeve 12 is fixedly arranged through the bottom of the simulation teaching fixed seat 10. The leather tube 13 is inserted into the leather tube sleeve 12, and the leather tube 13 is fixedly connected to the leather tube sleeve 12. The leather tube sleeve 12 is fixed at the bottom of the simulation teaching fixed seat 10, and the leather tube 13 is fixedly connected to the leather tube sleeve 12, which improves the firmness of the connection between the leather tube 13 and the simulation teaching fixed seat 10.
[0031] A trainer proposed by the utility model can conduct puncture training for nurses or doctors to improve the puncture success rate. A liquid adding tube 19 is fixedly arranged on one side of the top of the sealed liquid box 15. The arranged liquid adding tube 19 is convenient for adding liquid into the sealed liquid box 15. A liquid adding tube cover body 20 is arranged at the top of the liquid adding tube 19 in a threaded manner, which is convenient for covering the liquid adding tube 19 to prevent liquid leakage.
[0032] The non-invasive needle mechanism includes a hand-held block 5. A rope-passing hole 6 is longitudinally formed in the top of the hand-held block 5. A connecting rope 2 is fixedly arranged on the outer wall of the upper end of the simulation teaching target 9. The connecting rope 2 is convenient for connecting the simulation teaching target 9 and the hand-held block 5 together. The connecting rope 2 passes through the rope-passing hole 6 and extends downward. A limiting ball 7 is fixedly arranged at the bottom end of the connecting rope 2. The limiting ball 7 is in limiting cooperation with the bottom end of the rope-passing hole 6 to prevent the connecting rope 2 from passing upward through the rope-passing hole 6.
[0033] The non-invasive needle mechanism further includes a mounting vertical block 4. The mounting vertical block 4 is fixedly connected to the hand-held block 5. A non-invasive needle 8 is fixedly arranged on the side of the mounting vertical block 4 away from the hand-held block 5. The non-invasive needle 8 can pass through the needle-passing tube 11. Limiting buckle grooves 14 are arranged on the front and back sides of the hand-held block 5. An operator's thumb or ring finger can be buckled into the limiting buckle grooves 14, and through the limiting buckle grooves 14, it is convenient for the operator to hold the hand-held block 5.
[0034] To achieve a stable connection between the handheld block 5 and the connecting rope 2, a threaded hole penetrating through to the rope-passing hole 6 is provided on the outer wall of the handheld block 5. A limiting threaded block mechanism 3 is horizontally arranged in the threaded hole. The limiting threaded block mechanism 3 includes a limiting threaded block 31, and the limiting threaded block 31 is in threaded fit with the threaded hole. The connecting rope 2 is fixed by tightening the limiting threaded block 31 against it. That is, during the process of screwing the limiting threaded block 31, the limiting threaded block 31 moves along the threaded hole towards the rope-passing hole 6 and gradually abuts against the connecting rope 2. To prevent the limiting threaded block 31 from directly squeezing the connecting rope 2 and causing damage to it, a rotating groove 32 is provided inside the limiting threaded block 31, and a rotating block 34 is rotatably arranged in the rotating groove 32 through a rotating shaft 33. The outer side edge of the rotating block 34 extends beyond the outer side edge of the limiting threaded block 31 by a certain distance. As a result, during the process of rotating the limiting threaded block 31, the rotating block 34 will contact the connecting rope 2, and under the action of the rotating shaft 33, the rotating block 34 will have a slight rotational effect along with the connecting rope 2, ensuring that the connecting rope 2 is not directly squeezed but is squeezed after being properly adjusted in position, reducing the damage to the connecting rope 2. During operation, according to the needs of the user's puncture distance, the connecting rope 2 is pulled up or down to a suitable position, and the limiting threaded block 31 is rotated. Under the action of the rotating block 34 and the rotating shaft 33, the connecting rope 2 is fixed by being abutted against by the tightened limiting threaded block 31 and / or the rotating block 34, and thus the distance between the simulation teaching target 9 and the handheld block 5 can be adjusted to adapt to different people for puncture.
[0035] The working principle and usage method of the present utility model:
[0036] During use, first, according to the needs of the operator, the distance between the teaching target 9 and the handheld block 5 is adjusted. The connecting rope 2 is pulled up or down to a suitable position, and the limiting threaded block 31 is rotated. Under the action of the rotating block 34 and the rotating shaft 33, the connecting rope 2 is fixed by being abutted against by the tightened limiting threaded block 31 and / or the rotating block 34. Then, hold the handheld block 5 and drive the non-damaging needle 8 to insert into the needle-passing tube 11. When the non-damaging needle 8 successfully punctures, the non-damaging needle 8 just touches the pressure sensing switch 18. The pressure sensing switch 18 senses the pressure and transmits the pressure signal to the pressure controller. The pressure controller controls the electric valve 21 to open. At this time, it can be seen that red liquid flows into the leather tube 13, indicating successful puncture. On the contrary, if no red liquid flows out, it means the puncture is unsuccessful. The structure of the present utility model is simple, the operation is convenient, and the practicability is strong.
[0037] The above is only used to illustrate the technical solution of the present utility model, rather than to limit it; although the present utility model 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 described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; any equivalent structural or equivalent process transformation made by using the content of the specification and drawings of the present utility model, whether directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present utility model.
