Description

Technical Field

[0001] The present application relates to a catheter storage device during interventional procedures, belonging to the technical field of medical devices. Background Art

[0002] In endovascular interventional surgeries, catheters and microcatheters play a crucial role. In practice, a catheter usually represents a relatively thick tube used to enter blood vessels for interventional treatments such as angioplasty and stent implantation; while a microcatheter is a thinner tube for more delicate operations such as angiography and thrombus extraction. The diameter of a microcatheter is usually less than 0.5 mm, so it causes less damage to blood vessels during endovascular operations and is also easier to enter smaller blood vessels. Therefore, the importance of catheters in endovascular interventional surgeries is self-evident. Their selection and use will directly affect the treatment effect and the safety of patients.

[0003] The difference between a catheter and a microcatheter lies in the diameter, and there is no essential difference in structure. In the present application, catheters and microcatheters are collectively referred to as catheters.

[0004] During the intermittent placement of catheters during interventional procedures, they are usually placed in a hydrophilic-coated plate or box for easy access at any time and to maintain heparinization by keeping contact with heparinized saline. During use, doctors may need to place and remove catheters multiple times. When the catheter is not needed temporarily, it is generally placed in a plate or box to prevent damage or contamination. However, when performing complex interventional surgeries, multiple catheters will be used. The disorderly placement of catheters may cause chaos and even lead to the catheter being bent, affecting the continuation of the interventional surgery and then the quality and efficiency of the interventional surgery. Therefore, a device capable of orderly arranging catheters is needed. Summary of the Invention

[0005] The technical problem to be solved by the present application is how to orderly and properly store and place catheters during interventional surgeries.

[0006] To solve the above technical problem, the technical solution of the present application is to provide a catheter storage device during interventional procedures, including multiple fixing posts. On one side of each fixing post, there are multiple vertically distributed card slots. The card slots at the same height on all fixing posts are set as a group of card slots, and a group of card slots corresponds to placing one soaking storage strip; the soaking storage strip is a strip-shaped object with a notch and a hollow made of absorbent cotton, and the soaking storage strip is sequentially placed in each card slot of a group of card slots; the hollow of the soaking storage strip is used to store catheters.

[0007] Preferably, there are at least two fixing posts.

[0008] Furthermore, the bottom of the fixing post is provided with a fixing chassis, and the fixing chassis is fixed on the surgical instrument tabletop through a suction cup, a binding rope or a bolt.

[0009] Preferably, the cross-sectional shape of the card slot matches the outer contour of the infiltration storage strip, and the hollow shape of the infiltration storage strip matches the outer contour of the catheter to be stored.

[0010] Furthermore, the inner height of the card slot is greater than the outer diameter of the catheter to be stored, and the hollow height of the infiltration storage strip is less than the outer diameter of the catheter to be stored.

[0011] Preferably, snap-fit components are provided on both the upper and lower sides of the card slot.

[0012] Preferably, a liquid guide groove communicating with all the card slots is provided at the center of the fixing pile. A liquid guide cotton is provided in the liquid guide groove, and a liquid storage bottle is provided at the top of the fixing pile. The liquid guide cotton is inserted into the liquid storage bottle, and the liquid storage bottle contains heparinized saline.

[0013] Preferably, adjacent fixing piles are connected with cross connecting rods. A vertical sliding groove is provided on the other side of the fixing pile. The centers of the cross connecting rods are hinged, and both ends of the cross connecting rods are provided as sliders and arranged in the sliding grooves of the adjacent fixing piles.

[0014] Based on the above solutions, the catheter storage device provided by the present application has the following advantages:

[0015] 1. Effective classification: The device can place different types of catheters according to height, and corresponding identifiers can also be set beside the card slots of different heights to avoid confusion and cross-infection and improve operation efficiency;

[0016] 2. Convenient access: Through the device, the operator can conveniently access the required catheter, avoiding the problems of catheter entanglement and knotting and reducing the operation difficulty;

[0017] 3. Maintaining heparinization: The infiltration storage strip in the device can be saturated with heparinized saline to heparinize the catheter and avoid blood coagulation and thrombus formation;

[0018] 4. Catheter fixation: The device is equipped with snap-fit components to fix the catheter, avoiding catheter detachment or displacement and improving operation safety;

[0019] In summary, the catheter storage device has the advantages of classifying, accessing, heparinizing and fixing the catheter, etc., and can effectively improve the success rate and safety of interventional surgery. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, they do not have technical essence. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effects that the present application can produce and the purposes that can be achieved, should still fall within the scope that can be covered by the technical content disclosed in the present application. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" cited in this specification are only for the convenience of narration and are not used to limit the scope under which the present application can be implemented. The change or adjustment of their relative relationships, without substantial change of the technical content, should also be regarded as the scope under which the present application can be implemented.

[0026] The present application provides a catheter storage device during interventional procedures, which is used to store multiple catheters that may be used during interventional procedures, so that they are kept infiltrated with heparinized saline to maintain heparinization.

[0027] Refer to Figure 1 , the fixing device includes multiple fixing piles 1, Figure 1 As shown in

[0028] There are four fixing piles 1 at the bottom of the fixing pile 1, which serves as an example. Generally, at least two fixing piles 1 are provided. A fixing chassis 11 is arranged at the bottom of the fixing pile 1, and the fixing chassis 11 is fixed on the surgical instrument tabletop through connection methods such as suction cups, binding ropes, bolts, etc., so as to keep the fixing pile 1 stable; a plurality of card slots 12 distributed vertically are arranged on one side of the fixing pile 1. Figure 1 As shown in

[0029] Three card slots 12 are arranged on each fixing pile 1, which serves as an example. Of course, two or more than three card slots 12 can also be arranged. The card slots 12 at the same height on all the fixing piles 1 are a group of card slots, and a group of card slots corresponds to one infiltration storage strip 2. Figure 2, the infiltration storage strip 2 is a strip-shaped object with a notch and a hollow made of liquid-absorbing cotton material (such as sponge, etc.). The infiltration storage strips 2 are sequentially placed in each card slot of a group of card slots. The preferred cross-sectional shape of the card slot should match the cross-sectional shape of the infiltration storage strip 2, so that the infiltration storage strip 2 can be stuck in the card slot and not easily fall off; the hollow of the infiltration storage strip 2 is used to place the catheter to be stored. During use, the catheter is pressed into the hollow of the infiltration storage strip 2 from the notch of the infiltration storage strip 2. The inner height of the card slot and the hollow height of the infiltration storage strip 2 should be adapted to the outer diameter of the catheter to be stored. For example, the inner height of the card slot is greater than the outer diameter of the catheter to be stored, and the hollow height of the infiltration storage strip 2 is less than the outer diameter of the catheter to be stored. After the catheter to be stored is pressed into the hollow of the infiltration storage strip 2, the infiltration storage strip 2 can clamp the pressed-in catheter by its own elasticity.

[0030] In a further embodiment, snap-fit components can be provided on both the upper and lower sides of the card slot. After the catheter is pressed into the infiltration storage strip 2, it can be locked by the snap-fit components to further prevent the catheter from falling out of the infiltration storage strip 2.

[0031] See Figure 3 , a liquid guide groove 13 communicating with all the card slots 12 is provided in the center of the fixing pile 1. A liquid guide cotton is arranged in the liquid guide groove 13. A liquid storage bottle 14 is arranged on the top of the fixing pile 1. The liquid guide cotton is inserted into the liquid storage bottle 14. The liquid storage bottle 14 is used to hold heparinized saline. The liquid guide cotton conducts the heparinized saline to the infiltration storage strip 2 in the card slot 12, so that the infiltration storage strip 2 is saturated with heparinized saline, thereby maintaining the contact between the catheter stored in the infiltration storage strip 2 and the heparinized saline.

[0032] See Figure 4 , adjacent fixing piles 1 are connected with a cross link 3. A vertical sliding groove is arranged on the other side of the fixing pile 1. The center of the cross link 3 is hinged. Both ends of the cross link 3 are arranged as sliders in the sliding grooves of the adjacent fixing piles 1, so that the distance between the adjacent fixing piles 1 can be conveniently adjusted. At the same time, through the connection of the cross link 3, each fixing pile 1 forms an integral device. Further, multiple fixing piles 1 can be placed in a non-linear distribution, and the stability of the integral device is higher.

[0033] During interventional procedures, multiple catheters are usually used, and different catheters have different functions. During interventional surgery, catheters are prone to damage and cannot be used continuously, so they need to be protected. At the same time, during the operation in the blood vessel, the catheter is in contact with the blood and is prone to cause the formation of blood clots, so it needs to be heparinized to prevent the generation of thrombus. Placing different catheters in an orderly manner in the storage device provided by the present application can effectively avoid the occurrence of the above problems.

[0034] When using the storage device provided by the present application, first expand each fixing pile 1, fix it through the fixed chassis 11 after adjusting to a suitable spacing, inject heparin physiological saline into each liquid storage bottle 14, and complete the preparation work; during the intervention operation, place the catheter that is not temporarily used into the corresponding infiltration storage strip 2, so as to keep the catheter in contact with the heparin physiological saline, and the catheter can also be firmly fixed through the snap-fit component; when it is necessary to use the catheter that has been placed in the device, first open the snap-fit component, and pull out the catheter from one end, then the intervention operation can continue.

[0035] As described above, only the preferred embodiments of the present invention are provided, and there is no limitation in any form and substance to the present invention. It should be noted that for those of ordinary skill in the art in the technical field, without departing from the premise of the present invention, several improvements and supplements can still be made, and these improvements and supplements should also be regarded as the protection scope of the present invention. For those skilled in the art, without departing from the spirit and scope of the present invention, any equivalent changes such as slight modifications, decorations and evolutions made by using the technical content disclosed above are all equivalent embodiments of the present invention; at the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the substantial technology of the present invention still fall within the scope of the technical solution of the present invention.
