Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a bladder fixation device for urinary care. Background Technology

[0002] Urological care is the prevention, treatment, and rehabilitation management of diseases of the urinary system (kidneys, ureters, bladder, urethra). It covers core aspects such as postoperative recovery, infection control, and intervention for urinary dysfunction. Its focus is on maintaining the integrity of urinary organ function, preventing complications (such as urinary tract infections and urinary retention), and improving patients' quality of life through professional medical means (such as catheterization, bladder irrigation, and local drug delivery) and nursing techniques.

[0003] Current methods for administering medication and providing care for the urethra and bladder typically use urinary catheters laid along the urinary tract. The catheter is used for flushing, catheterization, and medication administration based on treatment needs and frequency. Traditional catheters are fixed to the bladder and urinary tract by fixing the tail end. Considering the impact of flushing treatment on the support of the catheter fixation point and the disruption of the sterile environment of the catheter by the entry and exit of urinary tract medication, frequent catheter changes are usually required for flushing and medication administration. The high frequency of catheter insertion and removal increases the risk of invasive procedures. There is a lack of a fixation device that reduces the risk of invasive procedures to meet the needs of urinary care. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing catheter-type fixation devices for drug delivery have a high risk of invasive operation when administering drugs at high frequencies. To address the problems of the existing technology, this invention provides a urinary care bladder fixation device.

[0005] The purpose and effect of this utility model are achieved by the following specific technical means: including a tube seat and a fixing strap, wherein the two ends of the tube seat are respectively connected to composite molded multi-channel pipes, one end is provided with an external tube as an external pipe, and the other end is provided with a conduit as an internal pipe;

[0006] The catheter is a three-way composite tube. The catheter has a side opening at the end relative to the insertion seat, and an inner septum is formed in the catheter that communicates with the side opening. A valve is formed in the section of the inner septum away from the side opening, and an inflation clamp is attached to the valve. The tubing extending from the inflation clamp is formed in a wrapping shape outside the inner septum. An inflatable limiting airbag is formed at the rear section of the catheter with an air valve head connected inside the limiting airbag. The air valve head tubing is distributed between the inside of the catheter and the outside of the inflation clamp.

[0007] The external tube is connected to a valve seat at one end relative to the tube seat, and a three-way tube seat and an external air tube are respectively connected to the valve seat. The external air tube extends into the external tube with a branch tube, and the end of the branch tube is connected to the air valve head. The three-way tube seat is provided with three Luer connector interfaces, and a shunt tube is formed along the inner end of the external tube by the three-way tube seat, and the end of the shunt tube is connected to the conduit.

[0008] The fixing strap is fixed to the insertion seat, and the fixing strap is a medical elastic cloth bandage.

[0009] A further preferred embodiment: the fixing band and the tube insertion seat are connected by a fixing ring on the side near the external tube, and the fixing ring and the fixing band are corrugated telescopic portions at both ends, and the fixing band is sewn with Velcro ends at both ends.

[0010] A further preferred embodiment: the catheter insertion seat has a limiting ring fitted on one side of the catheter, and the limiting ring is a fan-shaped plate molded from medical silicone.

[0011] A further preferred embodiment: a corrugated sleeve is embedded in the tube holder, and the corrugated sleeve is sleeved and fixed to the outside of the connecting pipe section between the conduit and the shunt pipe.

[0012] A further preferred embodiment: the valve between the inflation clamp and the inner septum is an anti-backflow valve structure with a cross-shaped tip cut.

[0013] A further preferred embodiment: the limiting airbag is in contact with the external tube segment of the catheter when it is normally contracted, and a leaflet-shaped silicone layer is formed on the surface of the limiting airbag at one end relative to the side tube opening.

[0014] The beneficial effects of this utility model are:

[0015] This urinary care bladder fixation device, combined with its tubing structure, enables multi-channel drug delivery control for the internal catheter. The balloon structures corresponding to the catheter and bladder fixation provide bladder support during long-term catheter placement. The various ports of the three-way stopcock, the inner septum within the catheter, and the inflatable clamp serve as drug delivery, output, and urinary catheterization pathways, respectively. During long-term catheter placement, the inflatable septum, which closes during bladder irrigation, allows for both irrigation and subsequent urinary catheter flushing, facilitating catheter maintenance and meeting the needs of long-term catheter placement. This significantly reduces the frequency of invasive procedures, improving the device's safety and practicality. Attached Figure Description

Inflation tube clamp Detailed Implementation

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the following description is provided in conjunction with the accompanying drawings. Figures 1-5 The present invention will be further described in detail below with specific embodiments. The following embodiments are merely examples for implementing the present invention. It must be noted that the disclosed embodiments do not limit the scope of the present invention. On the contrary, any modifications and refinements made without departing from the scope of the present invention are within the patent protection scope of the present invention.

[0024] A urinary care bladder fixation device includes a catheter seat 1 and a fixation strap 2. The catheter seat 1 has composite molded multi-port tubing connected to both ends. One end is provided with an external tube 4 as an external tubing, and the other end is provided with a catheter 3 as an internal tubing.

[0025] The catheter 3 is a three-way composite tube. The catheter 3 has a side port 13 at its end relative to the insertion seat 1. An inner septum 14 communicating with the side port 13 is formed in the catheter 3. A valve is formed in the section of the inner septum 14 away from the side port 13. An inflation clamp 17 is attached to the valve. The tube extending from the inflation clamp 17 is wrapped around the inner septum 14. An inflatable limiting airbag 15 is formed at the rear of the side port 13 of the catheter 3. An air valve head 16 is connected inside the limiting airbag 15. The tubes of the air valve head 16 are distributed between the inside of the catheter 3 and the outside of the inflation clamp 17.

[0026] One end of the external tube 4 is connected to a valve seat 7 relative to the tube seat 1, and a three-way tube seat 8 and an external air tube 9 are respectively connected to the valve seat 7. The external air tube 9 extends into the external tube 4 with a branch tube 10, and the end of the branch tube 10 is connected to the air valve head 16. The three-way tube seat 8 is provided with three Luer connector interfaces, and a diversion tube 11 is formed along the inner end of the external tube 4, and the end of the diversion tube 11 is connected to the conduit 3.

[0027] The fixing strap 2 is fixed to the insertion base 1. The fixing strap 2 is a medical elastic cloth bandage.

[0028] This type of urinary care bladder fixation device, based on the installation method of a urinary catheter, uses both catheter 3 and external catheter 4 as flexible tubing. Catheter 3 extends along the patient's urinary tract to the bladder urethral orifice, serving as an indwelling catheter within the bladder. The side port 13 at the end of catheter 3 serves as both the external urinary catheter port and the internal bladder medication and irrigation port. Simultaneously... Figure 4 As shown, the limiting balloon 16 of catheter 3 will be maintained between the bladder urethral opening and the side tube opening 13. Then, through the external air tube 9, an external air source is used to inflate the limiting balloon 16 along the branch tube 10 and the valve head 16, so that the limiting balloon 16 is maintained as shown. Figure 5 The inflated state shown is achieved by using the limiting balloon 16 to lock into the bladder urinary tract opening during inflation, thereby fixing and maintaining the position of the catheter 3.

[0029] Based on the above, the external tube 4 is externally connected to the subsequent drug delivery line and the urinary bag via the three-way tube seat 8 on the valve seat 7. The shunt tube 11 formed by the inward extension of the three-way tube seat 8 will eventually be connected to the catheter, corresponding to the inlet and outlet tubes of the inner septum tube 14 and the air tube of the inflation clamp 17, respectively.

[0030] During normal catheterization, bladder urine will enter the inner septum tube 14 through the side tube opening 13 and be discharged along the outlet tube. If bladder flushing and medication administration are required, the trachea can be inflated first to close the terminal inflation clamp 17. Figure 5 As shown, after the inflation clamp 17 expands, it will clamp and fix the valve at the end to block the connection between the side port 13 and the rear section of the inner septum 14. At this time, the bactericidal solution can be injected into the inner septum 14 through the input tube to complete the flushing of the inner septum 14 in the closed section. After the flushing is completed, the bactericidal solution is pumped out along the pipeline, and then the repositioning inflation clamp 17 is reopened. The flushing solution is injected into the bladder through the input tube. During the process, the flushing solution is continuously delivered into and out of the bladder along the pipeline by pumping in and out once by the cleaning device or syringe to complete the bladder flushing treatment.

[0031] Compared to traditional single-dose catheter flushing therapy and catheter-assisted catheterization, this fixation device, with its fixed structure and built-in tubing, enables long-term indwelling of the tubing. The multi-port tubing structure also allows for daily aseptic maintenance of the tubing, ensuring the safety of long-term indwelling tubing. This reduces invasive procedures required for multiple drug administration treatments, significantly lowers operational risks, and improves the safety and practicality of the fixation device.

[0032] like Figure 1 As shown, a fixing ring 6 is fixed at the connection end of the fixing band 2 and the insertion seat 1 on the side near the external insertion tube 4, and the two ends of the fixing ring 6 are corrugated telescopic parts between the fixing band 2 and the fixing band 2. The two ends of the fixing band 2 are sewn with Velcro ends. The fixator mainly uses the fixing band 2 externally placed on the insertion seat 1 as the fixing and limiting structure of the inner and outer sections of the tube. The fixing band 2 can be fixed to the patient's groin by wrapping with the Velcro at the end. The fixing ring 6 maintains the neutral position of the insertion seat 1 on the fixing band 2 to ensure the stability of the position of the tubes at both ends. The corrugated telescopic part of the fixing band 2 ensures the stability of the winding structure of the fixing band 2 and maintains the effective winding size.

[0033] Based on the above, a limiting ring 5 is fitted onto one side of the catheter 3 in the catheter seat 1. The limiting ring 5 is a fan-shaped plate made of medical silicone. The added limiting ring 5 can serve as a separation and limiting structure between the catheter 3 and the catheter seat 1. The limiting ring 5 separates the catheter 3 from the outside of the urinary tract and the catheter seat 1, and maintains the fixation of the catheter 3 to the external protrusion end of the urinary tract.

[0034] Furthermore, a corrugated sleeve 12 is embedded in the catheter seat 1, and the corrugated sleeve 12 is sleeved and fixed to the outside of the connecting section between the catheter 3 and the shunt tube 11, so as to fill the corrugated sleeve 12 section between the catheter 3 and the shunt tube 11, to provide a buffer tube that can be pulled and moved between the external tube 4 and the catheter seat 1, so as to avoid the pulling of the tube and the connection end of the catheter seat 1 after being pulled, which would damage the stability of the connection structure. At the same time, the telescopic section of the corrugated sleeve 12 can adapt to the bending and movement changes at both ends of the catheter 3 and the external tube 4, ensuring that the pulling of the tube during the patient's movement will not affect the normal connection.

[0035] Furthermore, the valve between the inflation clamp 17 and the inner septum 14 is an anti-retrograde valve structure with a cross-shaped tip incision, such as... Figure 4 As shown, the inner septum tube 14 segment is closed by compression closure of the valve after being compressed. Under normal conditions, the repositioning of the cross-shaped tip incision will not affect the inflow and outflow of liquid at both ends of the segment.

[0036] Furthermore, when the limiting balloon 15 is normally contracted, it fits into the external segment of the catheter 3. A leaf-shaped silicone layer is formed on the surface of the limiting balloon 15 at one end relative to the side opening 13. The relatively rigid expansion edge structure serves as the contact and fixation end between the limiting balloon 15 and the bladder urinary tract opening, ensuring the limiting effect of the limiting balloon 15.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions 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 solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
