Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to an elastomer kit with the function of lubricating a urinary catheter. Background Technique
[0002] Users of urinary catheters (such as intermittent urinary catheters) insert the catheter four to six times a day by themselves. Users carry a tube or package of lubricant with them to lubricate their urinary catheter before inserting the catheter. With the update and iteration of products, urinary catheters with lubricating functions have gradually emerged on the market.
[0003] Currently, the lubricating function of urinary catheters on the market mainly relies on coatings. The coating technology is relatively mature, but the requirements for coating technology are high, the investment in coating equipment is large, although it is mature but not necessarily stable, the defective rate of products is also high, the raw material liquid ratio of the coating is difficult to prepare, and the storage is difficult. Strict requirements are imposed on the equipment, and the production environment also needs to control temperature, humidity, etc. There are also a series of problems such as the possibility of the coating blocking the side holes of the urinary catheter. Even qualified urinary catheters need to be moistened before use, and there are requirements for the volume and duration of the moistening treatment. The process is cumbersome. Content of the Utility Model
[0004] (1) Technical Problems to be Solved
[0005] In view of the deficiencies of many existing technologies of coated urinary catheters, the utility model provides an elastomer kit with the function of lubricating a urinary catheter, which solves the problems mentioned in the above background technique.
[0006] (2) Technical Solutions
[0007] To achieve the above object, the utility model is realized through the following technical solutions: an elastomer kit with the function of lubricating a urinary catheter, assembled on the urinary catheter, including a housing and an elastic liquid storage sleeve. The elastic liquid storage sleeve is sleeved on the urinary catheter, and a cavity for storing lubricant is formed between the outer wall of the elastic liquid storage sleeve and the urinary catheter. The housing is sleeved outside the urinary catheter and the elastic liquid storage sleeve, and can drive the elastic liquid storage sleeve to slide synchronously when sliding.
[0008] Preferably, the elastic liquid storage sleeve includes an elastic sleeve body and upper and lower conical thin edges arranged at its upper and lower ends, and the ports of the upper and lower conical thin edges are slightly smaller than the outer diameter of the urinary catheter.
[0009] Preferably, a plurality of protruding blocks are circumferentially arranged at the upper end of the elastic sleeve body.
[0010] Preferably, the housing includes an upper section shell, a middle section shell and a lower section shell integrally formed. The inner diameter of the middle section shell is larger than the outer diameter of the elastic sleeve body, and the inner diameters at the joints of the upper section shell, the lower section shell and the middle section shell are slightly smaller than the outer diameter of the elastic sleeve body.
[0011] Preferably, the bottom end of the lower shell is closed and completely sleeved outside the catheter. The port of the upper shell is open, and its diameter is between the upper and lower port diameters of the trumpet-shaped joint of the catheter.
[0012] Preferably, the port diameter of the upper shell is smaller than the outer edge diameter of the clamping block.
[0013] (III) Beneficial effects
[0014] The utility model provides an elastomer kit with the function of lubricating a catheter, which has the following beneficial effects:
[0015] 1. When installing the elastomer kit with the function of lubricating the catheter, a syringe is inserted into the edge of the elastic sleeve body to fill the cavities of the elastic sleeve body and the catheter, so that the lubricant is stored therein. Then, the catheter with the elastic liquid storage sleeve and the lubricant is squeezed into the outer shell together. When the catheter needs to be unsealed and used, just hold the catheter joint and pull it out. Since the four clamping blocks above the elastic sleeve body will clamp the inner wall of the outer shell, the catheter will be separated from the elastic sleeve body when pulled out. At this time, the lubricant in the elastic sleeve body will lubricate the whole catheter, achieving the expected goal. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] An embodiment of the utility model provides an elastomer kit with the function of lubricating a catheter, as Figures 1-4 shown, which is assembled on the catheter 1 and includes an outer shell 2 and an elastic liquid storage sleeve 3.
[0022] The elastic liquid storage sleeve 3 is sleeved on the catheter 1, and a cavity for storing lubricant is formed between the outer wall of the elastic liquid storage sleeve 3 and the catheter 1. The outer shell 2 is sleeved outside the catheter 1 and the elastic liquid storage sleeve 3, and can drive the elastic liquid storage sleeve 3 to slide synchronously when sliding.
[0023] AsFigures 3-4 As shown, the elastic liquid storage sleeve 3 is made of a soft elastic material such as silicone, rubber, etc. The elastic liquid storage sleeve 3 includes an elastic sleeve body 31 and upper and lower conical thin edges 32 and 33 provided at its upper and lower ends. When filling the lubricant, first put the elastic liquid storage sleeve 3 on the catheter 1. When assembling the elastic liquid storage sleeve 3 and the catheter 1, first pass the elastic sleeve body 31 through the catheter 1 until the upper port touches the catheter connector. Then, inject the elastic sleeve body 31 through a syringe at the edge to fill the cavity of the elastic sleeve body 31 and the catheter 1, so that the lubricant is stored therein. The ports of the upper conical thin edge 32 and the lower conical thin edge 33 are both conical, and the ports are slightly smaller than the outer diameter of the catheter 1, so that it tightly wraps around the outside of the catheter 1 to prevent the lubricant in the elastic liquid storage sleeve 3 from flowing out.
[0024] Four protruding blocks 34 are circumferentially arranged at the upper end of the elastic sleeve body 31. The blocks 34 are used to be stuck on the outer shell 2 when the elastic liquid storage sleeve 3 is pulled out.
[0025] When the lubricant is injected into the elastic liquid storage sleeve 3, the catheter 1 with the elastic liquid storage sleeve 3 and the lubricant is squeezed into the outer shell 2 together.
[0026] As Figure 2 shown, specifically, the outer shell 2 includes an upper shell segment 21, a middle shell segment 22 and a lower shell segment 23 formed integrally. The inner diameter of the middle shell segment 22 is larger than the outer diameter of the elastic sleeve body 31, and the inner diameters at the joints of the upper shell segment 21, the lower shell segment 23 and the middle shell segment 22 are slightly smaller than the outer diameter of the elastic sleeve body 31.
[0027] The bottom end of the lower shell segment 23 is closed, and it completely covers the outside of the catheter 1 to prevent the lower segment of the catheter 1 from being contaminated. The port of the upper shell segment 21 is open, and its diameter is between the upper and lower mouth diameters of the trumpet-shaped connector of the catheter 1, so that it can be stuck on the connector. The port diameter of the upper shell segment 21 is smaller than the outer diameter of the block 34. When installing the outer shell 2, since the upper end of the elastic liquid storage sleeve 3 abuts against the catheter 1 connector, the elastic liquid storage sleeve 3 utilizes its flexibility to enable the upper shell segment 21 of the outer shell 2 to pass through the elastic liquid storage sleeve 3, so that the middle shell segment 22 is sleeved outside the elastic liquid storage sleeve 3. When the catheter 1 needs to be unsealed for use, hold the catheter 1 connector and pull it out. Since the four blocks 34 above the elastic sleeve body 31 will catch the top wall of the middle shell segment 22, the outer shell 2 will drive the elastic liquid storage sleeve 3 to separate from the catheter 1 when pulled out. At this time, the lubricant in the elastic sleeve body 31 will lubricate the entire catheter 1 to achieve the expected goal.
[0028] This elastic body kit can replace the production of coatings with cumbersome processes and high quality requirements. Fundamentally, it simplifies the process, optimizes the process, and reduces costs.
[0029] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
