Description

Three-cavity single-bag urinary catheter not easy to block

Technical Field

The utility model relates to an uropoiesis surgical medical treatment consumptive material technical field especially relates to a three chamber list bag ureters that are difficult for blocking.

Background

Three chamber single bag ureters are the medical consumables that the frequency of use is higher in urinary surgery, and some patients to having the urinary system hemorrhage or the urinary system to accept the operation often need give three chamber single bag ureters and last the bladder and wash to avoid the blood clot to stuff the bladder.

An existing common three-cavity single-bag urinary catheter structure is shown in fig. 1 and 2, and generally comprises a catheter body 1, a urinary catheter head 2 and a urinary catheter tail 3 are respectively arranged at two ends of the catheter body 1, three cavities are arranged at the urinary catheter tail 3, and respectively comprise an air bag water injection cavity 4, a liquid outlet cavity 6 and a flusher connection cavity 7, wherein a water injection hydraulic valve 5 is arranged on the air bag water injection cavity 4, the water injection hydraulic valve 5 can be connected with an injector to inject sterile water, the flusher connection cavity 7 can be connected with a flusher, a matched urinary catheter plug 8 is arranged at one side of the flusher connection cavity, two symmetrical strip-shaped side holes 9 are arranged on the side wall of the catheter body 1 close to the urinary catheter head 2, the side holes 9 are about 5mm in length and about 2mm in width, an air bag 10 is arranged behind the side holes 9, a flushing hole 11 for water inlet flushing is arranged on the side surface of the urinary catheter head 2, and the flushing hole 11 is generally circular and about 1mm in diameter;

the operation method comprises the following steps: the urinary catheter is smoothly remained according to the aseptic operation, wherein the air bag 10 can be filled with 10-50ml of water according to the situation, when the hematuria is serious, the urinary catheter plug 8 can be opened, the connecting cavity 7 of the flusher is connected with the infusion apparatus to be connected with the aseptic normal saline for bladder flushing, flushing fluid flows out from the side hole 9, the flushing speed is adjusted according to the hematuria degree, when no obvious bleeding exists, the flushing can be stopped, and the urinary catheter plug 8 is closed after local disinfection.

The three-cavity single-sac urinary catheter has the advantages that during the indwelling period of a patient, the situation that the three-cavity single-sac urinary catheter is blocked due to blood clots occurs occasionally, many times, blood clot strips are blocked at the position of the side hole 9 of the urinary catheter, the blood clots blocked at the position of the side hole 9 are difficult to clear, even if a doctor repeatedly washes the high-pressure bladder manually, the blood clots at the position are difficult to clear, at last, only a new urinary catheter can be replaced, and the new urinary catheter can often face the situation. The operation is repeated, the pain is brought to the patient, and the workload and the medical expense of the doctor are increased.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a three chamber single bag ureters that are difficult for the jam to solve above-mentioned problem.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a three chamber list bag ureters that are difficult for blockking up, includes the body, the both ends of body are ureter head and ureter afterbody respectively the ureter afterbody is provided with three chambers, is water injection chamber, play sap cavity and flusher connection chamber respectively the position that the body is close to the ureter head is provided with the gasbag, is provided with two mouths at the ureter head, is mutually independent respectively and washes mouth and delivery port, wherein the delivery port is located the tip intermediate position of ureter head, washes a mouthful and is located delivery port one side. Keep somewhere difficult clot jam of being in the ureter period, even if blockked up by the clot, because of its improvement delivery port position, the clot can wash rivers along with the bladder and get back to the bladder or flow through the delivery port that ureter port department newly established when manual bladder is washed, so can make the bladder wash the unobstructed and difficult jam of circulation of business turn over water, can wash along with unobstructed washing to the clot of getting back to the bladder and disintegrate for following rivers behind the littleer clot.

The utility model discloses a cancel the side opening, the method of resetting the delivery port, because the reason that rivers direction and the impact force direction that receives change, the clot jam condition of the delivery port that new position was newly established improves the front ureter and obviously reduces, even if blockked up also be convenient for the doctor and clear up by the clot, because of its improvement delivery port position, wash through the bladder, the clot can be in the same direction as bladder washes rivers and get back to the bladder or flow through the delivery port that the ureter port department was newly established, can make the bladder wash unobstructed and difficult the jam of circulation of business turn over water, can disintegrate along with unobstructed washing for littleer clot and wash out along with rivers after getting back to the clot of getting back to get back to the bladder, thereby solve the problem of vascular jam.

As a preferable technical scheme: the delivery port external diameter is greater than and washes the mouth, and the delivery port that preferentially establishes newly is bigger than original washing mouth diameter promptly, guarantees that the velocity of water outlet is greater than the velocity of water inflow to guarantee the effect of washing and the catheter urine drainage function. Compared with the traditional ureter, the improved ureter is not easy to be blocked by blood clots, so that the patient is relieved of pain caused by repeated manual bladder flushing or ureter replacement, and the comfort level of the patient during indwelling of the ureter is improved.

The improved ureter can greatly reduce the situation of blockage by blood clots, and a doctor is easy to dredge after blockage, thereby obviously lightening the operation burden of medical personnel and also obviously reducing the economic burden of a patient.

The urinary catheter is made of the same material, and is generally required to be replaced within 1 week due to blockage before improvement, and even the urinary catheter is replaced for several times in 1 day; after improvement, the usable time of the ureter can be prolonged to 1 month, the replacement period is greatly prolonged, the operation burden of medical personnel is obviously lightened, and the economic burden of a patient is also obviously reduced.

As a preferred technical scheme: the water outlet is circular, and the diameter of the water outlet is 3-5mm, and the water outlet is preferably 4 mm.

Compared with the prior art, the utility model has the advantages of: the utility model provides a ureter structure, difficult quilt of ureter is blockked up by the clot during keeping somewhere, even if blockked up by the clot, the clot can be in the same direction as high pressure rivers and get back to the bladder or flow along with water through the delivery port that newly establishes at the end to can keep the unobstructed of washing, the clot of getting back to the bladder can be along with usual washing disintegrate and wash out for following rivers behind the less clot, thereby solve vascular blockage's problem. This ureter can greatly alleviate the patient and relapse the bladder and wash and frequently change the discomfort of ureter, and the operation is also simple, has also obviously reduced doctor's work load and patient's medical expenses to the structure after the improvement is simpler, and the preparation technology is simpler, and cost reduction changes the popularization in clinical, the utility model discloses on clinical trial, doctor and patient all react well.
