Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to a urinary catheter dredging cleaning brush. Background Art
[0002] In order to relieve the symptoms of urinary incontinence and urinary retention caused by prostate diseases, bladder diseases, etc., urinary catheterization has become a necessary means. However, urinary catheterization is an invasive operation, which is prone to urinary tract infection, and the flocs produced can cause urinary catheter blockage. Therefore, for patients with long-term urinary catheterization, bladder irrigation is one of the measures to prevent and control urinary tract infection.
[0003] Frequent bladder flushing will also increase the risk of infection. The main reason is that the invasion of external fluid into the bladder will increase the risk of infection. In the existing method, direct unblocking through the urethra can solve the problem of urinary tract obstruction, and can also effectively reduce the risk of infection caused by the invasion of external fluid into the bladder. Because the urethra is narrow and long, when directly unblocking the urethra, it is necessary to take into account the full unblocking of the urethra while not invading the bladder. The cleaning brush in the existing cleaning method is directly exposed to the urethra to clean and unblock the urethra. On the one hand, it may cause impurities such as flocs in the urethra to be pushed into the bladder. On the other hand, the direct contact cleaning brush will also produce back and forth friction on other parts when scrubbing back and forth, which is easy to cause flocs to form inside the urethra. Therefore, a special urethra unblocking cleaning brush is needed to unblock it. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0028] like Figure 1 As shown, the utility model provides a urinary catheter cleaning brush, comprising:
[0029] The guide wire 1 has a brush body 11 at its end that can enter the urinary catheter 4; the brush body 11 is made of a flexible material, and when the brush body 11 is in the urinary catheter, its outer edge is bent to abut against the inner wall of the urinary catheter 4;
[0030] The brush cover 2 is sleeved on the brush body 11 to reduce the expansion range of the outer edge of the brush body 11;
[0031] The brush sleeve 2 is fixed with a drawing wire 3 which is wound around the guide wire 1 . The drawing wire 3 can move along the winding path on the guide wire 1 under the traction of external force, so that the brush sleeve 2 is displaced relative to the brush body 11 .
[0032] The utility model aims to pass the brush body 11 into the urinary catheter 4 indwelling in the patient's body through the guide wire 1, and use the brush body 11 to clean the inner wall of the urinary catheter 4, so as to avoid the formation of flocs on the inner wall of the urinary catheter 4 and cause urinary catheter blockage after the indwelling urinary catheter operation causes urinary tract infection, maintain normal urine drainage, and avoid the invasion of external liquid into the bladder to increase the risk of infection during bladder flushing; on the other hand, the utility model also prevents the brush body 11 from pushing the dirt on the inner wall of the urinary catheter 4 into the patient's bladder during the process of entering the urinary catheter 4 by the brush cover 2 arranged on the outside of the brush body 11, and can pull the brush cover 2 through the wire drawing 3 after entering the inside of the urinary catheter 4 to expose the brush body 11, so that the inner wall of the urinary catheter 4 can be cleaned by the brush body 11. It should be noted that in the actual use of the urinary catheter cleaning brush provided by the utility model, the brush body 11 is preferably a fiber ball, a cotton ball, a sponge ball, etc., which can achieve the purpose of cleaning the inner wall of the urinary catheter 4.
[0033] In the above embodiment, since the position of the drawing wire 3 when it is wrapped around the guide wire 1 is not fixed, it is difficult to determine the spiral path of the drawing wire 3 when it moves on the guide wire 1. This will cause the medical staff to pull the brush cover 2 by pulling the drawing wire 3, causing the displacement of the brush cover 2 on the central axis of the urinary catheter 4 to vary, thereby affecting the normal removal of the brush cover 2 from the inside of the urinary catheter 4.
[0034] In order to solve the above problems, Figure 2-4 As shown, in the preferred embodiment provided by the utility model based on the above embodiment, a notch 12 is provided on the guide wire 1 for limiting the position of the drawing wire 3;
[0035] The notch 12 is spirally formed on the guide wire 1 .
[0036] In the present embodiment, by embedding the drawing wire 3 into the spirally opened groove 12 on the guide wire 1, the moving path of the drawing wire 3 on the side of the guide wire 1 can be restricted, which can not only avoid the problem of the medical staff's displacement on the axis of the urinary catheter 4 being large or small when using the drawing wire 3 to remove the brush cover 2, but also avoid the problem that the drawing wire 3 is entangled with each other on the side of the guide wire 1 during the pulling process of the medical staff, which makes it difficult for the medical staff to pull the drawing wire 3, thereby avoiding the failure of removing the brush cover 2.
[0037] In order to facilitate the removal of the brush cover 2 from the brush body 11 inside the urethra 4, as shown in FIG. Figure 5As shown, in another embodiment provided by the utility model, an extension sleeve 21 extending toward the end of the urinary tube 4 is provided at the end of the brush sleeve 2, and the brush sleeve 2 can be displaced relative to the brush body 11 by pulling the extension sleeve 21;
[0038] The diameter of the extension sleeve 21 gradually decreases along the direction of the guide wire 1 to form a tapered sleeve structure, so as to reduce the contact area between the extension sleeve 21 and the inner wall of the urinary catheter 4 .
[0039] In this embodiment, by further providing an extension sleeve 21 at the end of the brush sleeve 2, the medical staff can clamp the other end of the extension sleeve 21 to tear the brush sleeve 2 off the brush body 11 after the brush sleeve 2 enters the appropriate position of the urinary catheter 4, so that the brush body 11 can be exposed to the inside of the urinary catheter 4 to clean the inner wall of the urinary catheter 4; on the other hand, this embodiment also reduces the contact area between the extension sleeve 21 and the urinary catheter 4 by providing a conical structure of the extension sleeve 21, thereby preventing the extension sleeve 21 from rubbing against the inner wall of the urinary catheter 4 and scraping off the dirt thereon during the process of the brush sleeve 2 entering the urinary catheter 4, and entering the patient's body as the extension sleeve 21 is extended, thereby reducing the risk of infection of the patient when cleaning the indwelling urinary catheter.
[0040] In order to further solve the problems raised by the above embodiments, different from the above embodiments, as Figure 6 , 8 As shown, in another embodiment provided by the utility model, an extension sleeve 21 extending toward the end of the urinary tube 4 is provided at the end of the brush sleeve 2, and the brush sleeve 2 is displaced relative to the brush body 11 by pulling the extension sleeve 21;
[0041] The extension sleeve 21 is provided with recesses 22 for accommodating impurities scraped off the inner wall of the urinary tube 4 ; the recesses 22 are arranged in a spiral shape along the axis of the extension sleeve 21 on the peripheral wall.
[0042] In this embodiment, spirally arranged recesses 22 are provided on the extension sleeve 21, so that the dirt scraped off by the extension sleeve 21 after friction with the inner wall of the urinary catheter 4 can be retained by the recesses 22, thereby preventing the dirt from entering the patient's body as the extension sleeve 21 is extended, thereby reducing the risk of infection to the patient when cleaning the indwelling urinary catheter.
[0043] In the above embodiment, the brush cover 2 needs to be completely removed by the pulling action of the wire drawing 3 or the extension sleeve 21 inside the urinary catheter 4 to expose the brush body 11 before the inner wall of the urinary catheter 4 can be cleaned. Since the brush body 11 has a certain length coverage range, it will take a long time for medical staff to control the wire drawing 3, making it difficult to improve the cleaning efficiency of the urinary catheter 4.
[0044] In order to solve the above problems, Fig. 9As shown, in another embodiment provided by the present utility model, the brush body 11 includes bristles 111, and the bristles 111 are arranged in a circular pattern on the guide wire 1;
[0045] The brush cover 2 is provided with a plurality of through holes 23 capable of accommodating the bristles 111 to pass through. When the brush cover 2 is displaced relative to the brush body 11 , the bristles 111 enter into the through holes 23 adjacent thereto and abut against the inner wall of the ureter 4 .
[0046] In the present embodiment, a through hole 23 is provided on the brush cover 2 for the bristles 111 to pass through, so that the brush cover 2 can be limited by the bristles 111 inserted into the through hole 23 after being moved a certain distance outside the patient's body, so that the bristles 111 protruding from the brush cover 2 can be used to clean the inner wall of the urinary catheter 4, thereby improving the efficiency of medical staff in cleaning the urinary catheter 4 using the cleaning brush provided in the present embodiment.
[0047] In order to enable medical personnel to obtain corresponding prompts of the depth of the guide wire 1 entering the patient's body, such as Figure 6-7 As shown, in another embodiment provided by the utility model, a ring-shaped convex mark 13 is provided on the guide wire 1 near its end, and the convex mark 13 is used to indicate the depth of the guide wire 1 entering the urinary catheter 4. Generally speaking, the depth of the urinary catheter in the human body is fixed, that is, the medical staff can judge whether the head of the brush body 11 of the guide wire 1 will reach the other end opening of the urinary catheter 4 according to the remaining length of the guide wire 1 at one end opening of the urinary catheter 4 outside the patient, thereby avoiding the brush body 11 directly invading the patient's bladder and causing unnecessary infection risks.
[0048] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
