[0044] See also Figures 1 to 3 The present embodiment provides a puncture kit, comprising a first sleeve 1, a first catheter 2, a first hose 4 and a second catheter 3. The first sleeve 1 has a first output end 11 and a first input end 12. The first input end 12 is provided with a first passage, and the first output end 11 is provided with a second passage; the first catheter 2 is arranged between the first output end 11 and the first input end 12, and the two ends of the first catheter 2 are respectively connected with the first passage and the second passage; the first hose 4 is arranged at the first output end 11 and extends outward, the first hose 4 is connected with the other end of the second passage, and the first hose 4 can be placed in an object to be injected; the second catheter 3 is detachably arranged in the first passage, a first steel bar 5 is arranged in the second catheter 3, and the first steel bar 5 protrudes from the end of the second catheter 3, the first steel bar 5 is placed in the first catheter 2, and the second catheter 3 is sleeved on the outside of the first catheter 2, and the second catheter 3 is used to drive the first steel bar 5 to move toward the second passage, so that the first steel bar 5 protrudes from the first hose 4 to puncture the side wall of the object to be injected.

[0045] In this embodiment, a first conduit 2 is provided inside the first sleeve 1. Figure 1 As shown, the first conduit 2 is coaxially arranged with the first sleeve 1, the first output end 11 of the first sleeve 1 has a second passage, the first input end 12 has a first passage, and the first conduit 2 is arranged between the first output end 11 and the first input end 12. The material of the first hose 4 can be a silicone material, and the middle part of the second hose has a hollow pipe. The second conduit 3 is connected to the first conduit 2, and the first conduit 2 is connected to the first hose 4 through the second passage.

[0046] Specifically, the diameter of the second conduit 3 is greater than that of the first conduit 2. The second conduit 3 can pass through the first passage and be sleeved on the outside of the first conduit 2. A first steel bar 5 is provided inside the second conduit 3. The first steel bar 5 can be understood as an extremely fine steel wire. The first steel bar 5 can be placed in the first conduit 2, such as Figure 3As shown, the first steel bar 5 is covered by the first catheter 2 and the second catheter 3 from the inside to the outside in sequence. The first catheter 2 can guide the first steel bar 5 to the second passage and introduce it into the first hose 4. When puncture is required, the first steel bar 5 can protrude from the end of the first hose 4 to achieve the puncture operation on the object to be injected.

[0047] It should be noted that the object to be injected shown in this embodiment can be a blood vessel model or a patient or animal that needs a puncture operation. At the same time, the puncture kit shown in this embodiment is not limited to injection operations, but can also be used in various application environments such as sampling and drainage.

[0048] Through the combination of the second catheter 3 and the first steel bar 5, the puncture operation can more accurately locate and puncture the side wall of the object to be injected, reducing the risk of accidental injury and damage to surrounding tissues. The first hose 4 is connected to the second passage, and can directly transport the injection object to the target position. Since the first hose 4 is located inside the object to be injected, by controlling the movement of the second catheter 3 and the first steel bar 5, the side wall of the object to be injected can be accurately punctured to ensure that the injection object is accurately injected into the target area, ensuring the safety and reliability of the puncture operation, while reducing the risk of accidental injury to surrounding tissues. The setting of the first hose 4 can provide guidance for the first steel bar 5, so that the entire puncture kit can be changed according to the actual puncture path of the object to be injected, which is convenient for use.

[0049] See also Figure 1 and Figure 5 In some embodiments, it further includes a first pressing plate 6, which is arranged at the end of the second conduit 3, the first pressing plate 6 is detachably connected to the second conduit 3, and the first steel bar 5 is fixedly connected to the first pressing plate 6.

[0050] In this embodiment, the first pressing plate 6 is detachably connected to the second conduit 3, which can be understood as the first pressing plate 6 being detachably connected to the end of the second conduit 3, which can be in the form of threaded connection, snap-fit ​​connection, etc., and the second conduit 3 can be detached from the first pressing plate 6. The first steel bar 5 is fixedly connected to the first pressing plate 6, and after the puncture operation of the object to be injected is completed, the first steel bar 5 and the first pressing plate 6 can be removed, so that the hollow structure of the second conduit 3 can be used to further perform operations such as injection and suction, thereby reducing repeated puncture operations of the object to be injected and improving efficiency.

[0051] See also Figure 4 In some embodiments, a syringe 7 is further included, and the syringe 7 has a first injection end 71. The first injection end 71 can be sealed and connected to the second conduit 3 to inject the liquid in the syringe 7 into the object to be injected through the second conduit 3, the first conduit 2, the second passage and the first hose 4 in sequence.

[0052] The syringe 7 is a tool for injecting medicine or other liquids into the human body or animal body; it usually consists of a syringe, a piston and a needle. The syringe is a hollow cylindrical container, usually made of transparent material, so that the capacity and flow of the medicine can be observed. It has scale lines for accurately measuring the capacity of the medicine. There is usually a tapered connection port at the upper end of the syringe for fixing the needle. The piston is a sealed cylindrical part that fits tightly with the inner wall of the syringe. By pushing or pulling the piston, the entry and exit of the medicine can be controlled. The needle is a slender metal pipe connected to the syringe, with a sharp tip for puncturing the skin and injecting the medicine. The size and type of the needle can vary according to different injection requirements. When using the syringe 7, first suck the medicine to be injected into the syringe, and then push the piston to push the medicine out of the tip of the needle to puncture the skin or other parts and inject the medicine into the body. The use of the syringe 7 can ensure the accurate dosage of the medicine and the injection of the target part. The syringe 7 is widely used in the medical and veterinary fields for operations such as drug administration, vaccination, and blood sampling.

[0053] The liquid in the syringe 7 first enters through the second conduit 3, then passes through the first conduit 2, the second passage, and finally is injected into the object to be injected through the first hose 4. This flow path ensures the sequential injection of the liquid, so that the medicine or other liquid can enter the object to be injected according to the adjusted path. Through the sealed connection between the first injection end 71 and the second conduit 3, the liquid in the syringe 7 can be injected without leakage. The sealed connection ensures the safety and reliability of the injection process and prevents the loss or contamination of the medicine or other liquid.

[0054] See also Figure 1 In some embodiments, the first sleeve 1 has a first visible area, which is arranged along the extension direction of the first catheter 2; a dosage mark 13 is also provided on the outer wall of the first sleeve 1, and the dosage mark 13 is arranged along the extension direction of the first visible area.

[0055] The dosage mark 13 can be as follows Figure 1 The scale mark 13 is used to indicate the volume of the liquid or the dosage, so that the user can accurately measure and control the dosage of the injection. This marking design can improve the accuracy and precision of the injection and avoid overdosing or underdosing.

[0056] In some embodiments, the first sleeve 1 is made of glass, and the first visible area is the cylinder of the first sleeve 1. In this embodiment, the cylinder refers to the tubular structure of the first sleeve 1. When the first sleeve 1 is made of glass, the entire first sleeve 1 is a transparent structure, and the first visible area can be understood as the cylinder of the first sleeve 1.

[0057] In some embodiments, a sealing ring is further included, and the sealing ring is arranged at the connection between the second conduit 3 and the first conduit 2. The sealing ring can be an annular structure made of silicone, and the inner hollow area of ​​the sealing ring is smaller than the outer diameter of the first conduit 2. When the second conduit 3 is sleeved outside the first conduit 2, the sealing ring is placed between the first conduit 2 and the second conduit 3 to block the gap between the first conduit 2 and the second conduit 3. When injecting liquid, the liquid in the second conduit 3 will flow into the first conduit 2 and enter the first hose 4.

[0058] See also Figure 3 In some embodiments, the first conduit 2 protrudes from the first passage to the first input end 12. This structure facilitates the connection between the second conduit 3 and the first steel bar 5 and the first conduit 2.

[0059] See also Figure 1 In some embodiments, a first anti-slip pattern is further provided on the circumference of the first output end 11. The first anti-slip pattern can increase the surface friction of the first sleeve 1, making it easier to hold and control, reducing hand tremors or unstable factors, and reducing the risk of accidental slippage or loss of the user during injection.

[0060] Through the combination of the second catheter 3 and the first steel bar 5, the puncture operation can more accurately locate and puncture the side wall of the object to be injected, reducing the risk of accidental injury and damage to surrounding tissues. The first hose 4 is connected to the second passage, and can directly transport the injection object to the target position. Since the first hose 4 is located inside the object to be injected, by controlling the movement of the second catheter 3 and the first steel bar 5, the side wall of the object to be injected can be accurately punctured to ensure that the injection object is accurately injected into the target area, ensuring the safety and reliability of the puncture operation, while reducing the risk of accidental injury to surrounding tissues. The setting of the first hose 4 can provide guidance for the first steel bar 5, so that the entire puncture kit can be changed according to the actual puncture path of the object to be injected, which is convenient for use.

[0061] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of the utility model, this does not limit the scope of patent protection of the utility model.
