Description

Technical Field

[0001] The utility model relates to a receiving and fixing device, in particular to a catheter receiving and fixing device for popliteal vein catheterization. Background Art

[0002] Deep vein thrombosis of the lower extremities refers to the coagulation of venous blood in the deep veins of the lower extremities. At present, one of the commonly used interventional treatment methods in surgery is thrombolysis through popliteal vein puncture and catheterization at the popliteal fossa. Thrombolytic drugs are given through the thrombolytic catheter to treat deep vein thrombosis of the lower extremities. This method allows the thrombolytic drugs to act directly on the thrombus site, and the thrombolytic effect is good. During the treatment process of popliteal vein puncture and catheterization, the thrombolytic catheter needs to be retained in the patient's popliteal fossa for a long time (7-14 days). The exposed part of the catheter needs to be fixed and the exposed part of the thrombolytic catheter must be in a sterile environment.

[0003] At present, the excessive length of the catheter after popliteal vein catheterization is mostly fixed with medical tape or transparent dressing. The specific operation is: coil the excess part of the catheter, place it on the gauze that fits the patient's skin, and use medical tape or transparent dressing to fix the coiled catheter and gauze together. The port of the exposed part of the catheter is connected to the infusion tee for drug administration. This fixation method has the following defects: although there is gauze between the catheter and the skin, it may still cause abrasion of the patient's skin and even cause pressure sores; at the same time, the patient's limb movement will also cause the thrombolytic catheter to bend, so that the thrombolytic drug cannot reach the thrombus site smoothly; in severe cases, the catheter will shift or even fall off. After the thrombolytic catheter shifts or falls out, the catheter needs to be re-placed, which directly affects the treatment effect and poses a great safety hazard, which will have a great impact on the patient's body and economy.

[0004] The Chinese invention patent with application number 202110597292.1 discloses a spiral coiled storage and quick fixation device for a jugular vein thrombolytic catheter. In the prior art, the jugular vein thrombolytic catheter is coiled and stored in its storage shell, and then the thrombolytic catheter is fixed by a catheter routing fixing structure. In the device, the port of the exposed part of the catheter is completely placed in the inner cavity structure of the storage shell, which brings inconvenience to the drug administration treatment after the popliteal vein catheterization.

[0024] Embodiment A catheter storage and fixing device for popliteal vein catheterization

[0025] In this embodiment, Figure 1 , Figure 2 As shown, a catheter storage and fixing device for popliteal vein catheterization includes a storage fixture for coiling, storing and fixing the catheter, and also includes an adhesive component 8 for fixing the storage fixture below the popliteal fossa. The storage fixture includes a storage shell, a catheter coiling column 2, a catheter inlet and outlet 5, and a sealing sticker 7 for covering the coiled catheter.

[0026] The storage shell includes a bottom surface 11 of a circular plate structure, and also includes an edge 12 fixedly connected to the edge of the bottom surface 11 and arranged in the height direction. The connection between the edge 12 and the bottom surface 11 is rounded, which can reduce the discomfort of wearing. The catheter winding column 2 is a cylindrical structure, fixedly arranged on the bottom surface 11 of the storage shell, and arranged on the same side as the edge 12; the side wall of the catheter winding column 2 is a concave arc, where the concave means that the side wall of the catheter winding column 2 is concave toward the axis of the catheter winding column 2, so as to facilitate the winding of the catheter. A fixed cover 3 is fixedly arranged on one side of the catheter coiling column 2 away from the bottom surface 11 of the storage shell. The fixed cover 3 is circular and has a size larger than that of the catheter coiling column 2, so that a space for accommodating the catheter coiling is formed between the fixed cover 3, the catheter coiling column 2, and the storage shell. After the catheter is coiled on the catheter coiling column 2, the larger fixed cover 3 can effectively prevent the catheter from scattering from the catheter coiling column 2, thereby playing a fixing effect. Furthermore, the fixed cover 3 is arranged with four grooves 4 in an array in the circumferential direction, and the catheter coiled under the fixed cover 3 can be observed at any time through the grooves 4. The storage shell and the fixed cover 3 are made of hard materials with a fixing effect, such as plastic, metal, etc. The catheter coiling column 2 can be made of the same material as the storage shell and the fixed cover 3. The catheter coiling column 2 can also be made of a softer material, such as sterile foam, etc., to prevent the catheter from bending during the coiling process and affecting the treatment. The fixed cover 3 is made of a transparent material, which can further facilitate the observation of the coiled catheter.

[0027] A conduit inlet and outlet 5 is provided on the edge 12 of the storage shell. The conduit inlet and outlet 5 is an inverted "Ω"-shaped opening groove. The internal shape of the opening groove is adapted to the cross section of the conduit. The opening size of the opening groove is smaller than the outer diameter of the conduit, so that the conduit can be stuck in the conduit inlet and outlet 5 and relatively fixed. Furthermore, a fixing buckle 6 is provided on the upper part of the conduit inlet and outlet 5; the fixing buckle 6 is a strip-shaped structure, one end of which is hinged to the edge 12 of the storage shell, and the other end is clamped with the storage shell through a protruding portion. The side of the fixing buckle 6 facing the conduit inlet and outlet 5 is an arc that is adapted to the conduit. When the fixing buckle 6 is buckled on the conduit inlet and outlet 5, the fixing buckle 6 and the conduit inlet and outlet 5 together enclose a circular channel that is adapted to the outer diameter of the conduit. After the conduit is placed in the conduit inlet and outlet 5, the fixing buckle 6 is buckled to further fix the conduit.

[0028] At least two of the catheter inlets and outlets 5 are arranged at intervals. In this embodiment, four catheter inlets and outlets 5 are arranged at the edge 12 of the storage shell in a manner of 60° circumferential angle between each two, covering the 180° circumferential angle range of the storage shell. When in use, the four catheter inlets and outlets 5 with the appropriate direction are selected for use, which can not only adjust the direction of catheter extraction according to the characteristics of the catheter placement position of different patients, but also the extracted catheter is located outside the entire catheter storage and fixing device, which is convenient for drug administration or other operations after catheter placement.

[0029] The storage fixture also includes a sealing patch 7, which is a sterile transparent patch. In this embodiment, the sealing patch 7 is connected to the edge 12 of the storage shell where the catheter inlet and outlet 5 is not provided, which can facilitate the fitting operation of the sealing patch 7. The catheter inlet and outlet 5 is provided on the side of the storage shell away from the sealing patch 7. A release paper (not shown in the figure) is adhered to the sealing patch 7. When the catheter is coiled, the release paper is torn off, and the sealing patch 7 is fitted from the end connected to the storage shell to the end not connected to the storage shell. In order to ensure the fixing effect and the sterile environment of the catheter, the size of the sealing patch 7 is larger than the size of the storage shell, so that the sealing patch 7 can completely cover the storage fixture.

[0030] The adhesive component 8 is in the form of a sheet, and includes a circular main adhesive portion 81 that matches the shape of the bottom of the storage shell. The side of the main adhesive portion 81 facing the skin can be arc-shaped, so as to better fit the skin. The adhesive component 8 also includes a plurality of auxiliary fixing strips 82 that are integrally arranged with the main adhesive portion 81 and radially extend from the main adhesive portion 81, so as to further enhance the fixing effect. The side of the adhesive component 8 facing the storage fixture is fixedly connected to the bottom of the storage fixture. The side of the adhesive component 8 away from the storage fixture is provided with glue that can be attached to the skin, and the glue is covered with release paper (not shown in the figure). Specifically, the adhesive component 8 is a medical foam dressing, and the material can be soft silicone or the like.

[0031] When using this embodiment, peel off the release paper on the sticking component 8, stick the sticking component 8 under the popliteal fossa, and when sticking, point one of the catheter inlets and outlets 5 toward the catheter insertion point of the popliteal fossa, while ensuring that the other catheter inlet and outlet 5 faces the direction of subsequent drug administration and treatment, insert the catheter led out of the popliteal fossa into the catheter inlet and outlet 5 facing the popliteal fossa, coil the excessively long catheter on the catheter coiling column 2, and insert the end of the coiled catheter into the catheter inlet and outlet 5 facing the direction of subsequent drug administration and treatment, buckle the fixing buckle 6 of the catheter inlet and outlet 5 fixed with the catheter, tear off the release paper on the sealing sticker 7, and cover the sealing sticker 7 on the storage shell, the catheter coiling column 2, and the catheter inlet and outlet 5.
