Technical field
The utility model belongs to medical instruments field, is related to a kind of anticlogging balloon expandable catheter.
Background technique
Catheter be with instrument made of natural rubber, silicon rubber or polyvinyl chloride, can be per urethram inserted into bladder with
Drainage of urine.Existing catheter is most frequently used with three-cavity catheter, and three-cavity catheter has the gas injection channel of air bag, note
The reservoir channel of liquid and the urethral catheterization passage of urethral catheterization, air bag are fixed in order to facilitate in catheter body, and reservoir channel is for carrying out wing
Guang rinses, and to prevent urinary infection, urethral catheterization passage is for connecting urinal discharge urine.
In Clinical Practice on Urinary Surgery, bladder internal haemorrhage, vesical calculus and cystospasm cause catheter to block
Major reason, existing catheter urethral catheterization hole aperture and limited amount, effective drainage channel usually vulnerable to clot, calculus even
It is the mucous membrane of urinary bladder blocking of spasm, causes inadequate drainage.Cystirrhagia forms the patient of blood clot or vesical calculus, if not in time
Its bladder is rinsed or is rinsed and is not thorough, will cause urethral catheterization blockage, it is likely that causes life danger to patient.In addition,
Easily there is cystospasm in the patient of retention catheterization, leads to urethral catheterization blockage, drainage is obstructed, and frequent bladder irrigation and replacement is led
Urinary catheter not only can form security risk to patient, also increase the routine work amount of medical personnel.Therefore, developing one kind can
Effectivelying prevent the catheter of blood clot in bladder, calculus or mucous membrane of urinary bladder obstruction nozzle is very necessary for patient and is
It is advantageous.
Utility model content
According to the above-mentioned deficiencies of the prior art, the utility model provides a kind of anticlogging balloon expandable catheter, can
It is effectively prevent blood clot in bladder, calculus or mucous membrane of urinary bladder obstruction catheter, mitigates patient and medical worker's burden.
A kind of anticlogging balloon expandable catheter described in the utility model, which is characterized in that including catheter tube body,
Urethral catheterization hole and liquid injection hole are offered in the tube body head side wall, urethral catheterization hole is connected to tube cavity, the tube body head
It is provided with air bag on the outer wall of rear end, gas injection channel and reservoir channel are offered on the tube wall of the tube body, the gas injection is logical
Road one end interlinks with air bag, and the other end and the gas injection interface of tube body tail portion interlink, described reservoir channel one end and fluid injection
Hole interlinks, and the other end and the fluid injection interface of tube body tail portion interlink, and the tube body head end is the one of split type connection
Degradable end, the material of the degradable end are biodegradable material.
Biodegradable material described in the utility model can be selected polylactic acid material, polyethanol acrylic materials and its
Copolymer etc..If the degradation of polylactic acid in vivo is mainly carried out with the non-enzymatic hydrolysis method of ester bond, in-between product is cream
Sour (sugared metabolite), and lactic acid can enter the tricarboxylic acid cycle of body metabolism, finally be metabolized to water and carbon dioxide, pass through
Urethra, urine, skin etc. excrete in a variety of manners.The degradable end being made using biodegradable material, when
After urethral catheterization hole blocks, new access way is formd after degradable end degradation, has reached the anticlogging purpose of catheter,
Extend the anti-clogging time of catheter, solves the susceptible to plugging difficult medical problem of present catheter.
Wherein, preferred embodiment is as follows:
The urethral catheterization tube head is bent upwards composition arcuate structure, and catheter is facilitated to be inserted into.
N group annular protrusion is provided in the tube body head side wall, the urethral catheterization hole and liquid injection hole are located at adjacent
Between annular protrusion.Urethral catheterization hole and liquid injection hole are easy to be attached on mucous membrane of urinary bladder, cause mucosal congestion and edema, it is possible to which obstruction is logical
Road, therefore annular protrusion is added, avoid urethral catheterization hole and liquid injection hole from being attached on mucous membrane of urinary bladder.
The tube cavity is evenly arranged with the supporting element of annular.Catheter is generally silica gel hose, is inserted into patient's body
It is interior to be easy to be squeezed by the urethra of patient flat, be easy to happen blocking, therefore annular supporting element is added and plays the role of support, avoid by
It squeezes flat.
Be adhesive with block piece on the tube body tail portion front end outer wall, the block piece include it is semicircle and with outside tube body
What wall was pasted pastes portion and pastes outwardly extending blocking portion in portion.The only interior fixed function of the air bag of catheter, if not adopting
Outer fixation is taken, when patient posture changes, catheter can be moved into bladder sometimes, increase the damage to mucous membrane of urethra, together
Shi Rongyi brings bacterium outside urethra into urethra and causes urinary infection.Therefore, block piece is added, it can be to avoid catheter to bladder
Interior movement reduces damage and unnecessary bacterium infection to mucous membrane of urethra.
Beneficial effect possessed by the utility model is: (1) the degradable end being made using biodegradable material
Head can effectively reduce urethral catheterization blockage incidence or extend the urethral catheterization blockage period, avoids and be repeatedly inserted into catheter to patient
Bring considerable distress, improves therapeutic effect, reduces the burden of medical staff；(2) it joined annular protrusion, avoid urethral catheterization
Hole and liquid injection hole are attached on mucous membrane of urinary bladder and cause congestion and edema to it；(3) annular support member in tube cavity is played to tube body
The effect of inner cavity support, avoids being crowded flat and blocks；(4) it joined block piece, can be moved to avoid catheter into bladder,
Reduce the damage and unnecessary bacterium infection to mucous membrane of urethra.
