Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a guide wire retention puncture kit. Background Technology

[0002] A central venous catheter (CVC) is a specially designed catheter inserted through the skin into a deep vein (such as the subclavian vein, internal jugular vein, or femoral vein) for the infusion of special medications, hypertonic solutions, and hyperalimentation solutions. It can also be used to measure central venous pressure. The guidewire is typically made of high-strength, highly flexible materials, such as stainless steel or platinum-tungsten alloy, to ensure it is not easily kinked or broken during insertion.

[0003] After the procedure using existing techniques is completed, the guidewire should be removed from the body before suturing and fixation. However, in busy work situations, there is a chance that the guidewire might be forgotten to be removed. A guidewire remaining in a vein as a foreign body can cause inflammation, manifesting as redness, swelling, and pain. Simultaneously, the retained guidewire, as a foreign body, provides a potential source of bacterial infection. A guidewire in a vein can also obstruct blood vessels, inducing or exacerbating venous thrombosis, and even causing pulmonary embolism, thus endangering life. Furthermore, if the retained guidewire causes damage to blood vessels and the heart due to body movement, it can also endanger the patient's health and even life. In short, a guidewire remaining in a vein has numerous potential problems. Summary of the Invention

[0004] (I) Technical problem to be solved: In view of the shortcomings of the existing technology, this utility model provides a guide wire retention puncture pack, which has the advantage that the tool needed for the next suturing step can only be taken out after the guide wire is inserted, thus solving the problem in the existing technology that there is a probability that the guide wire is not removed before suturing.

[0005] (II) Technical Solution: To achieve the goal of removing tools needed for the next suturing step only after inserting a guidewire, this utility model provides the following technical solution: a guidewire retention prevention puncture pack, comprising a puncture pack body, wherein the puncture pack body is provided with a guidewire placement area and a suturing tool placement area, the suturing tool placement area being divided into a locked state and an open state, wherein the internal suturing tools cannot be removed in the locked state; a contact point is provided on the inner outer surface of the guidewire placement area, and the other end of the contact point is connected to an electromagnet via an electric wire; a [missing information - likely a device or feature] is provided on one side of the suturing tool placement area. A limiting block is provided, with a hollowed-out limiting hole inside. A movable channel is provided between the limiting block and the electromagnet, and a limiting rod is placed inside the channel. The limiting rod is made of a magnetic material and its position corresponds to the limiting hole. The length of the limiting rod is greater than that of the movable channel, and a spring is provided between the limiting rod on the outer side and the movable channel. In the locked state, one end of the limiting rod is located inside the limiting hole, and the other end is located inside the movable channel. In the open state, one end of the limiting rod is located inside the movable channel, and the other end is magnetically attracted by the electromagnet.

[0006] Preferably, the guidewire placement area is annular.

[0007] Preferably, an adhesive strip is provided on the inner outer surface of the guidewire placement area, and the number of adhesive strips is greater than or equal to one, which is evenly distributed along the inner outer surface of the guidewire placement area.

[0008] Preferably, a baffle is provided on the outer circumference of the limiting rod, and one side of the baffle is connected to the spring. When the equipment is in the locked state, the other side of the baffle is pressed against the outer surface of the limiting block.

[0009] Preferably, the number of the limiting rod and the limiting hole is greater than or equal to one.

[0010] Preferably, the limiting block is connected to a limiting cover, which covers the upper part of the suture tool placement area.

[0011] Preferably, the limiting block and the limiting cover are an integral structure.

[0012] Preferably, the upper end of the suture tool placement area is provided with a groove along the side surface.

[0013] (III) Beneficial Effects: Compared with the prior art, this utility model provides a guidewire retention prevention puncture kit, which has the following beneficial effects:

[0014] 1. This anti-guidewire retention puncture pack utilizes contact points on the inner surface of the guidewire placement area and an electromagnet and limiting rod inside the puncture pack to lock and open the suture tool placement area. Only when medical staff remove the used guidewire and place it back in the placement area do the contact points engage with the guidewire, forming a circuit. This energizes the electromagnet, causing it to become magnetic and attract the limiting rod, thus removing the limiting effect and allowing the suture tool placement area to open. Compared to existing technologies, this significantly reduces the risk of medical staff forgetting to remove the guidewire due to busy schedules. Previously, if the guidewire was left inside the body, it could become a foreign object, endangering the patient's health and potentially causing serious medical accidents. This intelligent anti-guidewire retention mechanism greatly improves the safety and reliability of surgical procedures, ensuring that every surgery is completed to the highest standards and providing patients with a more reassuring treatment experience.

[0015] 2. This type of guide wire retention puncture pack sets the guide wire placement area in a circular shape and then sets an adhesive strip on its inner surface. When placing the guide wire, the guide wire is placed around the circular placement area, and the adhesive strip is used to make the guide wire fit against the inner surface of the guide wire placement area, ensuring that the guide wire can trigger the contact mechanism while preventing the guide wire from getting tangled.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 A puncture kit for preventing guide wire retention includes a puncture kit body 1. Inside the puncture kit body 1 are a guide wire placement area 2 and a suture tool placement area 3. The suture tool placement area 3 has a locked state and an open state. In the locked state, the suture tool cannot be removed. After a guide wire is placed inside the guide wire placement area 2, the locked state changes to the open state, allowing the suture tool to be removed for the next step. The inner outer surface of the guide wire placement area 2 is provided with contacts 20. The other end of each contact 20 is connected to an electromagnet 4 via a wire. This circuit structure is powered by a battery. The electromagnet 4 circuit structure is existing technology and will not be described in detail here. The specific location of the battery is not shown in the accompanying drawings, but it can be distributed according to actual conditions. In this embodiment, there are two contacts 20. Utilizing the characteristic that guide wires are mostly made of conductive alloy material, when the guide wire simultaneously touches both contacts 20, the electromagnet 4 circuit is connected, the electromagnet 4 is energized, and a magnetic force is generated. A limiting block 5 is provided on one side of the placement area 3. When the limiting block 5 is fixed, the suturing tool is limited inside the placement area and cannot be removed. The limiting block 5 is hollowed out to form a limiting hole 50. A movable channel 10 is provided between the limiting block 5 and the electromagnet 4. A limiting rod 11 is placed inside the channel. The limiting rod 11 is made of magnetic material and its position corresponds to the limiting hole 50. The length of the limiting rod 11 is greater than that of the movable channel 10. A spring 12 is provided between the limiting rod 11 on the outside and the movable channel 10. The spring 12 can ensure that when the electromagnet 4 is de-energized and the magnetic force disappears, the limiting rod 11 will be pushed back to its original position and continue to limit the limiting block 5. In the locked state, one end of the limiting rod 11 is located inside the limiting hole 50 and the other end is located inside the movable channel 10, so that the limiting block 5 is locked and the suturing tool inside cannot be removed. In the open state, one end of the limiting rod 11 is located inside the movable channel 10 and the other end is magnetically attracted by the electromagnet 4, and the limiting block 5 regains its freedom.

[0023] Please see Figures 1-3 The guide wire placement area 2 is circular; the inner outer surface of the guide wire placement area 2 is provided with an adhesive strip 21, the number of adhesive strips 21 is greater than or equal to one, and they are evenly distributed along the inner outer surface of the guide wire placement area 2. When placing the guide wire, the guide wire is placed around the circular placement area, and the adhesive strip 21 is used to make the guide wire adhere to the inner surface of the guide wire placement area 2, so as to ensure that the guide wire can trigger the contact 20 mechanism while avoiding the guide wire from getting tangled.

[0024] In this embodiment, please refer to Figure 1 A baffle 110 is provided on the outer circumference of the limiting rod 11. One side of the baffle 110 is connected to the spring 12. When the equipment is in the locked state, the other side of the baffle 110 is pressed against the outer surface of the limiting block 5. The addition of the baffle 110 can facilitate the assembly of the equipment.

[0025] Please see Figure 4 The number of limit rods 11 and limit holes 50 is greater than or equal to one, so as to prevent the limit block 5 from rotating around the limit rod 11 when the limit rod 11 is circular, thus ensuring the stability of the locked state.

[0026] Please see Figures 3-4 The limiting block 5 is connected to the limiting cover 51, which covers the upper part of the suture tool placement area 3. The limiting block 5 and the limiting cover 51 are an integral structure. The upper end of the suture tool placement area 3 is provided with a groove 6 along the side surface, which allows the user to easily remove the limiting cover 51.

[0027] In summary, compared with the prior art, this anti-guidewire retention puncture kit uses the adhesive strip 21 to make the guidewire fit against the inner surface of the guidewire placement area 2, ensuring that the guidewire can trigger the contact 20 mechanism while preventing the guidewire from getting tangled. At the same time, the contact 20 triggers the locking device, avoiding the possibility that the guidewire may be forgotten to be removed during busy work, resulting in the guidewire remaining in the body as a foreign object and causing medical accidents.
