Description

Technical Field

[0001] The utility model belongs to the technical field of medical instruments, and particularly relates to a medical catheter. Background Art

[0002] A catheter is a tube inserted into the bladder through the urethra for draining urine. It is a tube made of natural rubber, silicone rubber or polyvinyl chloride. It can be inserted into the bladder through the urethra to drain urine. After the catheter is inserted into the bladder, there is an airbag near the head end of the catheter to fix the catheter in the bladder and prevent it from slipping out easily. The drainage tube is connected to a urine bag to collect urine.

[0003] Currently, the general catheter uses a circular balloon design and the balloon is far from the front end of the catheter, making the front end of the catheter more prominent. When a patient uses the catheter, the spherical balloon on the catheter in the patient's bladder has a larger area after being inflated with water, so that the spherical balloon has a larger contact area with the patient's bladder, and the sharp part at the front end of the catheter will cause damage and irritation to the mucosa in the bladder, thus causing more irritation to the bladder and bringing discomfort symptoms to the patient.

[0004] Traditional catheters generally adopt a design with one drainage hole. This kind of catheter will cause the patient's urine to drain smoothly. When a patient uses a traditional catheter, due to the relatively high position of the upper drainage hole, a certain amount of urine needs to accumulate in the bladder before the urine can flow into the catheter through the upper drainage hole and then be discharged to the required storage bag through the end of the catheter. At this time, there will still be residual urine at the bottom of the bladder. At this time, the residual urine will drain out of the body through the gap between the catheter and the urethra, resulting in wet clothes and increasing the occurrence of urinary tract infections, bringing inconvenience to patients and medical staff. Therefore, the present device provides a medical catheter. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a medical catheter for the deficiencies of the prior art to solve the above-mentioned technical problems.

[0006] The embodiment of the utility model adopts the following technical scheme: It includes a catheter for assisting a patient in catheterization. An airbag is arranged on the catheter. After being inserted into the bladder part, the airbag expands by injecting water or inflating to play a limiting role. The airbag is butterfly-shaped and integrally formed with the front end of the catheter. Upper drainage holes and lower drainage holes for the patient's urine to drain are arranged on the catheter. The upper drainage holes and the lower drainage holes are respectively located above and below the airbag and are symmetrical to each other.

[0007] After the device is inserted into the required treatment position of the patient, the balloon provides inflation and is fixed to the bladder. The balloon is butterfly-shaped, reducing the contact between the balloon and the trigone of the bladder, reducing urinary tract irritation symptoms, alleviating the discomfort symptoms of the patient, and being able to drain the residual urine in the bladder more efficiently, improving the discomfort symptoms of the patient and reducing the occurrence of urinary tract infections. At the same time, the tip of the catheter head will not cause irritation and damage to the bladder mucosa.

[0008] Further, the balloon is located near the front end of the catheter. The balloon is in a contracted state before use and assumes a butterfly shape after being filled with water or inflated.

[0009] Further, the upper drainage hole and the lower drainage hole are arranged facing the same side.

[0010] Further, a urine discharge hole is provided at the end of the catheter.

[0011] Further, a water injection tube is provided on one side of the tail of the catheter. The interface of the water injection tube and the syringe is in a matching state. The water injection tube is connected to the balloon and is not connected to the upper drainage hole and the lower drainage hole. The balloon is in a sealed state after being inflated or filled with water. A rubber valve is provided at the end of the water injection tube.

[0012] Further, the catheter is made of an anti-corrosion material;

[0013] Since the catheter is inserted into the bladder for a long time, the catheter is easily corroded, shortening the service life of the catheter, requiring regular replacement of the catheter, increasing the patient's expenses, and imposing an economic burden on the patient. Through the anti-corrosion design of the catheter, the service life of the catheter can be extended, avoiding the pain caused to the patient by replacing the catheter, and solving the problem of the short service life of traditional medical catheters.

[0014] The above at least one technical solution adopted in the embodiment of the present utility model can achieve the following beneficial effects:

[0015] When the catheter is in the patient's bladder, the urine in the patient's bladder flows into the catheter through the upper drainage hole and the lower drainage hole at the front end of the catheter, and then flows out of the body through the urine discharge hole and into the required storage bag;

[0016] When a patient needs to use a urinary catheter, first insert the head end of the urinary catheter into the urethral orifice, and then slowly send it into the bladder. Next, draw the required amount of water with a syringe, connect the injection port of the syringe to the water injection tube, and then inject water into the balloon through the water injection tube by pushing the syringe to make the balloon expand. The expansion of the balloon will make the urinary catheter stay in the bladder and not fall off by itself, achieving a limiting effect, ensuring that there is no risk of the urinary catheter falling off under normal use conditions, improving the treatment effect. When it is not necessary to inflate or inject water into the balloon, the water injection tube at the tail end of the urinary catheter can be closed through the rubber valve provided at the end of the water injection tube.

[0025] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present invention.

[0026] The technical solutions provided by the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] An embodiment of the present invention provides a medical catheter, including a catheter 1 for assisting in urinary catheterization of patients. A balloon 2 is provided on the catheter 1, which is inflated by injecting water or air after being inserted into the bladder to play a limiting role. The balloon 2 is butterfly-shaped and integrally formed with the front end of the catheter 1. The catheter 1 is provided with an upper drainage hole 3 and a lower drainage hole 4 for discharging urine of the patient. The upper drainage hole 3 and the lower drainage hole 4 are respectively located above and below the balloon 2 and are symmetrical to each other.

[0028] After the device is placed at the treatment position of the required patient, the balloon 2 provides inflation and is fixed at the bladder. The butterfly-shaped balloon 2 reduces the contact between the balloon 2 and the bladder trigone, reduces urinary tract irritation symptoms, alleviates the discomfort symptoms of the patient, and can more efficiently drain the residual urine in the bladder, improving the discomfort symptoms of the patient and reducing the occurrence of urinary tract infections. At the same time, the sharp tip of the front end of the catheter 1 will not cause irritation and damage to the bladder mucosa.

[0029] In a further preferred embodiment of the present invention, the balloon 2 is located close to the front end of the catheter 1. The balloon 2 is in a contracted state before use and assumes a butterfly shape after being injected with water or air.

[0030] Currently, the general design of the catheter 1 uses a circular balloon 2 and the balloon 2 is far from the front end of the catheter 1, making the front end of the catheter 1 more prominent. When the patient uses the catheter 1, the spherical balloon 2 on the catheter 1 in the patient's bladder has a larger area after being injected with water, so that the spherical balloon 2 has a larger contact area with the patient's bladder, and the sharp part at the front end of the catheter 1 will cause damage and irritation to the mucosa in the bladder, thus causing more irritation to the bladder and bringing discomfort symptoms to the patient. However, by designing the balloon 2 of the catheter 1 into a butterfly shape in this device, the contact area between the balloon 2 and the bladder can be reduced, and the irritation to the bladder can be reduced. At the same time, through the design of the balloon 2 close to the front end of the catheter 1, the balloon 2 is almost in a close state with the front end of the catheter 1 after being inflated by injecting water, reducing the irritation and damage caused by the protruding part at the front end of the catheter 1 to the bladder mucosa, alleviating the discomfort symptoms of the patient, and improving the treatment effect.

[0031] In a further preferred embodiment of the present invention, the upper drainage hole 3 and the lower drainage hole 4 are arranged facing the same side.

[0032] Traditional urinary catheters 1 generally adopt a design with a single drainage hole. This type of urinary catheter 1 can cause unsmooth urine drainage in patients. When patients use traditional urinary catheters 1, due to the relatively high position of the upper drainage hole 3, a certain amount of urine needs to accumulate in the bladder before the urine can flow into the urinary catheter 1 through the upper drainage hole 3, and then be discharged to the required storage bag through the end of the urinary catheter 1. At this time, there will still be residual urine at the bottom of the bladder. At this time, the residual urine will drain out of the body through the gap between the urinary catheter 1 and the urethra, resulting in wet clothes and increasing the occurrence of urinary tract infections, bringing inconvenience to patients and medical staff. However, in this device, through the design of the upper drainage hole 3 and the lower drainage hole 4 on the urinary catheter 1, when patients use the urinary catheter 1, after a certain amount of urine accumulates in the patient's bladder, the urine flows into the urinary catheter 1 through the upper drainage hole 3 of the urinary catheter 1 and is discharged to the required storage bag through the end of the urinary catheter 1. At this time, the residual urine on the side will slowly flow into the urinary catheter 1 through the lower drainage hole 4 and will also be discharged to the required storage bag through the end of the urinary catheter 1. Therefore, the residual urine in the bladder can flow out, avoiding the long-term storage and accumulation of residual urine, alleviating the symptoms, reducing the occurrence of infections, improving the discomfort symptoms of patients, and reducing the workload of nursing staff and the resistance of patients to wearing urinary catheters.

[0033] In a further preferred embodiment of the present utility model, a urine discharge hole 5 is provided at the end of the urinary catheter 1;

[0034] When the urinary catheter 1 is in the patient's bladder, the urine in the patient's bladder flows into the urinary catheter 1 through the upper drainage hole 3 and the lower drainage hole 4 at the front end of the urinary catheter 1, and then is discharged out of the body through the urine discharge hole 5 and flows into the required storage bag.

[0035] In a further preferred embodiment of the present utility model, a water injection pipe 6 is provided on one side of the tail of the urinary catheter 1. The interface of the water injection pipe 6 is adapted to the interface of a syringe. The water injection pipe 6 is connected to the balloon 2 and is not connected to the upper drainage hole 3 and the lower drainage hole 4. The balloon 2 is in a sealed state after inflation or water injection. A rubber valve 7 is provided at the end of the water injection pipe 6;

[0036] When a patient needs to use the urinary catheter 1, first insert the head end of the urinary catheter 1 into the urethral orifice and then slowly send it into the bladder. Then, draw the required amount of water with a syringe, connect the injection port of the syringe to the water injection pipe 6, and then inject water into the balloon 2 through the water injection pipe 6 by pushing the syringe to make the balloon 2 expand. The expansion of the balloon 2 can make the urinary catheter 1 not fall off by itself in the bladder, playing a limiting role, ensuring that there is no risk of the urinary catheter 1 falling off under normal use conditions, improving the treatment effect. When the balloon 2 does not need to be inflated or injected with water, the rubber valve 7 provided at the end of the water injection pipe 6 can be used to close the water injection pipe 6 at the tail of the urinary catheter 1.

[0037] In a further preferred embodiment of the present utility model, the urinary catheter 1 is made of anti-corrosion material;

[0038] Since the urinary catheter 1 is inserted into the bladder for a long time, the urinary catheter 1 is prone to corrosion, shortening the service life of the urinary catheter 1. It is necessary to regularly replace the urinary catheter 1, which increases the expenditure of the patient and imposes an economic burden on the patient. Through the anti-corrosion design of the urinary catheter 1, the service life of the urinary catheter 1 can be extended, avoiding the pain brought to the patient by replacing the urinary catheter 1, and solving the problem of the short service life of the traditional medical urinary catheter 1.

[0039] The above are only the embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the scope of the claims of the present utility model.
