Description

Technical Field

[0001] This utility model relates to the field of medical and nursing technology, and in particular to an automatic flushing device for reducing urinary catheter infections. Background Technology

[0002] A urinary catheter is a medical device used to introduce or drain urine. It is often used for patients who are unable to urinate normally due to surgery, illness, coma, or other reasons. It helps to drain urine, monitor urine volume, and maintain the normal function of the urinary system and the patient's water and electrolyte balance.

[0003] Automatic flushing devices can flush the urinary catheter to prevent impurities, blood, bacteria, etc. from accumulating in the catheter or bladder, avoiding blockages that affect urine drainage or cause complications such as infection. Flushing can remove these substances, keep the catheter unobstructed, reduce the risk of infection, and promote patient recovery.

[0004] However, existing flushing devices have shortcomings. In actual flushing, once the inside of the catheter becomes clogged with impurities, conventional continuous water flow flushing becomes ineffective. These impurities adhere tightly to the inner wall of the catheter, and ordinary water flow cannot generate enough impact force to flush them away, causing the impurities to remain inside the catheter, severely affecting the overall cleaning effect and reducing the actual value of flushing. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] In view of the problems of the above-mentioned automatic flushing device for reducing urinary catheter infection, this utility model is proposed.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an automatic flushing device for reducing urinary catheter infection, comprising a hollow column and at least one liquid storage bottle disposed outside the top of the column, wherein a flushing pipe extending from the bottom to the outside of the column is disposed inside the column, and at least one connecting pipe is disposed at the top of the flushing pipe to keep it in communication with the liquid storage bottle.

[0008] It also includes a mounting cylinder connected to the outside of the column, on which a pressure frame with one end in contact with the flushing pipe slides through, and the pressure frame and the mounting cylinder are elastically connected by a spring;

[0009] It also includes a servo motor installed on the outside of the column. The output shaft of the servo motor is provided with an extrusion roller that contacts the pressure frame. The outer contour of the extrusion roller is divided into an arc segment and a circular segment with the output shaft of the servo motor as the center. The circumference of the circular segment is greater than the circumference of the arc segment.

[0010] The extrusion wheel is controlled by a servo motor to rotate continuously. The pressure frame contacts the arc segment and is controlled by it to squeeze the flushing pipe, reducing its cross-sectional area. The extrusion wheel continues to rotate, and the pressure frame contacts the circular segment and is controlled by it to squeeze the flushing pipe, thus blocking the water flow.

[0011] As a preferred embodiment of the automatic flushing device for reducing urinary catheter infection described in this utility model, the pressure frame is composed of a slide rod, a wear-resistant block, and a square block. The slide rod is slidably inserted through one end of the mounting cylinder. The wear-resistant block is fixedly connected to the outer end of the slide rod and contacts the extrusion wheel. The square block is fixedly connected to the inner end of the slide rod and extends into the column, and the square block is connected to a spring.

[0012] In a preferred embodiment of the automatic flushing device for reducing urinary catheter infection described in this utility model, the length of the block is greater than the diameter of the flushing tube.

[0013] In a preferred embodiment of the automatic flushing device for reducing urinary catheter infection described in this utility model, the number of the liquid storage bottles is three, which are distributed in a circular and equidistant manner, and the number of the connecting pipes is the same as the number of liquid storage bottles.

[0014] In a preferred embodiment of the automatic flushing device for reducing urinary catheter infection described in this utility model, the top end of the connecting pipe is provided with a connector and connected to a corresponding storage bottle through the connector, and an adjusting valve is provided on the connecting pipe.

[0015] As a preferred embodiment of the automatic flushing device for reducing urinary catheter infection described in this utility model, the flushing pipe is provided with a connector at its bottom end and a one-way valve at the connector, and a pad is provided on the flushing pipe away from the block.

[0016] The beneficial effects of this invention are as follows: The pressure frame and squeeze wheel work together to compress the flushing tube, thus continuously applying pressure. During this process, the cross-sectional area of ​​the flushing tube dynamically changes. Simultaneously, the special structure of the round end and arc segment enables a periodic cycle of closing and opening the flushing tube. When the flushing tube is closed, the cleaning fluid gradually converges; upon opening, the converged cleaning fluid, under the pressure difference, rushes towards the catheter with greater pressure. This design significantly increases the flushing pressure, effectively enhances the overall flushing effect, ensures a more thorough cleaning of the catheter, and improves infection prevention.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0026] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale.

In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0027] Reference Figures 1-4 As an embodiment of this utility model, an automatic flushing device for reducing urinary catheter infection is provided, which includes a hollow column 1 and at least one liquid storage bottle 2 disposed on the outside of the top of the column 1. The liquid storage bottle 2 is filled with flushing fluid. The column 1 creates a height difference between the liquid storage bottle 2 and the urinary catheter to facilitate the downward flow of the flushing fluid. A flushing pipe 3 is disposed inside the column 1, with its bottom end extending outside the column 1. The flushing pipe 3 is a flexible tube, and at least one connecting pipe 4 is disposed at the top of the flushing pipe 3 to keep it in communication with the liquid storage bottle 2.

[0028] There are three storage bottles 2, which are evenly distributed around each other. By using three storage bottles 2, the flushing fluid in a single storage bottle 2 can be quickly switched to the next storage bottle 2 after it is used up, reducing replacement time and improving flushing efficiency. The number of connecting tubes 4 is the same as the number of storage bottles 2. The top of the connecting tube 4 is equipped with a connector and is connected to the corresponding storage bottle 2 through the connector. The connecting tube 4 is equipped with a regulating valve, which can adjust the flow rate of the flushing fluid in the storage bottle 2 to prevent the flow rate from being too fast or too slow and affecting the flushing effect. The bottom of the flushing tube 3 is equipped with a connector for connecting a urinary catheter, and a one-way valve is provided at the connector to prevent urine from flowing back into the flushing tube 3.

[0029] like Figure 3 and Figure 4 As shown, it also includes a mounting cylinder 5 connected to the outside of the column 1. A pressure frame with one end in contact with the flushing pipe 3 slides through the mounting cylinder 5, and the pressure frame and the mounting cylinder 5 are elastically connected by a spring 8. The spring 8 enables the pressure frame to have elastic force, so that it can move back and forth in conjunction with the extrusion roller 10.

[0030] The pressure frame consists of a slide rod 6, a wear-resistant block, and a square block 7. The slide rod 6 slides through one end of the mounting cylinder 5. The wear-resistant block is fixedly connected to the outer end of the slide rod 6 and contacts the extrusion wheel 10. The square block 7 is fixedly connected to the inner end of the slide rod 6 and extends into the column 1. The square block 7 is connected to the spring 8. The length of the square block 7 is greater than the diameter of the flushing pipe 3, which facilitates the complete compression of the flushing pipe 3 and prevents the formation of compression dead angles. A pad is provided on the flushing pipe 3 away from the square block 7. The pad can cooperate with the square block 7 to prevent the flushing pipe 3 from still having a gap with the inner wall of the column 1 after the square block 7 has compressed the flushing pipe 3.

[0031] It also includes a servo motor 9 installed outside the column 1. The output shaft of the servo motor 9 is provided with an extrusion roller 10 that contacts the pressure frame. The outer contour of the extrusion roller 10 is divided into an arc segment 101 and a circular segment 102 with the output shaft of the servo motor 9 as the center. The circumference of the circular segment 102 is greater than the circumference of the arc segment 101.

[0032] The squeezing wheel 10 is continuously rotated by the servo motor 9. The pressure frame contacts the arc segment 101 and is controlled by it to squeeze the flushing tube 3, reducing its cross-sectional area. The squeezing wheel 10 continues to rotate, and the pressure frame contacts the circular segment 102 and is controlled by it to squeeze the flushing tube 3, blocking the water flow. Through the rotation of the squeezing wheel 10, the arc segment 101 and the circular segment 102 periodically contact the pressure frame, thereby causing the flushing tube 3 to periodically repeat the opening and closing process. During the closing phase, the flushing fluid gathers inside the flushing tube 3; during the opening phase, the flushing fluid flows downward and has greater water pressure, resulting in stronger flushing force on the catheter and more effective cleaning of impurities on the inner wall of the catheter, thus improving the infection prevention effect.

[0033] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
