Description
Technical Field
The utility model relates to the technical field of medical equipment, especially, relate to a leak protection urine gasbag catheter.
Background
The english name Foley Catheters of balloon Catheters is also known as Foley Catheters. Balloon catheters are widely used in urology surgery, and are often used for dysuria, urinary bladder injury, after urology surgery, and the like. The balloon catheter has the characteristics of simple operation, stable internal fixation, no need of adhesive tape fixation, convenience in nursing and the like. When the balloon catheter is used, the balloon catheter needs to be inserted into the urethra of a human body, the medium is filled into the balloon to expand the balloon, and the communicating port between the bladder and the urethra is clamped after the balloon enters the bladder. However, due to various factors in clinic, the balloon catheter often has unplanned tube drawing, and how to reduce the slippage rate of the catheter is a problem which needs to be solved urgently at present. For this reason, a balloon for a catheter has been studied.
For example, the patent of invention named as "catheter" disclosed in chinese patent document with application number CN201811512554.4 and publication date of 2019, 3 and 8, discloses a catheter, which relates to the technical field of medical instruments, and comprises a main conduit and a plurality of air bags located at the head of the main conduit; the air bags are arranged on the outer wall of the main pipeline and are arranged at intervals along the circumferential direction of the main pipeline; a drainage channel and a plurality of water injection channels are arranged inside the main pipeline; drainage holes communicated with the drainage channel are formed between the air bags on the main pipeline, and one end, far away from the air bags, of the drainage channel is communicated with the outside; the plurality of water injection channels are communicated with the plurality of air bags, and each water injection channel is communicated with at least one air bag. When one or more air bags leak, the rest air bags which do not leak can continue to work normally so as to ensure that the main pipeline continues to be fixed relative to the bladder and the drainage holes are positioned in the bladder. The disadvantages are that: 1. the air bags are arranged outside the main pipeline at intervals, a gap area is formed between the air bags, and a gap is easy to appear between the main pipeline and the urethra, so that the catheter is easy to leak; 2. the main pipeline is uniformly supported by the supporting force of the air bags in the circumferential direction, after one air bag fails, the circumferential stress of the main pipeline is unbalanced, and although the air bag can still block the urethral orifice of the bladder, the lateral leakage at the outer side of the main pipeline is easily caused; 3. the separate arrangement of the air bags can generate pressure distributed at intervals on the inner wall of the bladder, and cause discomfort to the human body.
Therefore, it is necessary to design a balloon catheter which has better fit with the urethral orifice in the bladder and can prevent urine leakage.
SUMMERY OF THE UTILITY MODEL
The utility model discloses overcome the gasbag structure of gasbag catheter among the prior art and the laminating performance of urethral orifice in the bladder is poor causes easily not enough of urine leakage, provides a leak protection gasbag catheter, one of the purposes of the utility model is that the laminating nature of urethral orifice is good in gasbag and the bladder, and the block is stable, prevents that the gasbag catheter from leaking urine.
The second purpose of the utility model is to form a double-layer structure by the auxiliary balloon and the balloon, and the auxiliary balloon is limited with the urethra when the balloon is damaged or leaked, so as to prevent the catheter from directly dropping off.
In order to achieve the above purpose, the present invention adopts the following technical solution.
An anti-leakage air bag catheter comprises a main pipeline and an air bag; the main pipeline penetrates through the air bag, the air bag is in a shuttle shape with two small ends and a large middle, and the two ends of the air bag are hermetically attached to the main pipeline; a drainage channel and a control channel are arranged in the main pipeline, and the control channel is communicated with the air bag; the drainage channel and the control channel can be communicated with the outside; one end of the main pipeline close to the air bag is provided with a drainage hole communicated with the drainage channel.
One end of the catheter, which is provided with the drainage hole, extends into the human body, and drainage of body fluid of the human body to the outside is completed through the drainage hole and the drainage channel; the shuttle-shaped surface of the air bag is more easily attached to the urethral orifice in the bladder, and a conical plug structure is formed at the matching part of the air bag and the urethral orifice, so that urine leakage can be effectively prevented when the air bag catheter is used; the clamping is stable, the stress on the surface of the air bag is uniform, and the leakage cannot occur.
Preferably, a sealing cover is arranged at one end, close to the air bag, of the main pipeline, and the end face, back to the air bag, of the sealing cover is spherical. The friction damage to the urethra in the process of being placed into the bladder of the main pipeline is reduced through the sealing cover, and the stimulation to a human body is reduced.
Preferably, one end of the control channel far away from the air bag is provided with a one-way control valve. The water injection amount of the air bag can be conveniently controlled at any time; the flow direction of water flow is limited, and the water in the control channel is prevented from flowing backwards and outwards.
Preferably, the drainage apertures are located in the wall of the main conduit between the cover and the bladder. The gasbag expands in the bladder, and the width size of gasbag is greater than the size of trunk line, and only gasbag surface and bladder laminating, drainage hole and bladder surface separation prevent that the drainage hole from being stopped up.
Preferably, an auxiliary bag is arranged on a main pipeline in the air bag, and an injection channel communicated with the auxiliary bag is arranged on the main pipeline. When in use, the water body is firstly introduced to expand the auxiliary bag and then the air bag is expanded. When the catheter is used, the condition of air bag breakage or expansion is generated, the auxiliary bag can replace the air bag to complete sealing and limiting between the main pipeline and the bladder urethral orifice, the air bag catheter is prevented from being leaked or directly separated from the urethra, and subsequent replacement is facilitated.
Preferably, the auxiliary bag is located at a middle position of the airbag, and an outer side surface of the auxiliary bag is in contact with an inner side surface of the airbag. Because the gasbag is the big shuttle-shaped structure in the middle of the both sides is little, and the auxiliary bag is located the intermediate position of gasbag and compares other positions that the auxiliary bag set up in the gasbag, and the volume that the auxiliary bag can set up is bigger to the supplementary spacing ability of auxiliary bag is stronger, improves supplementary spacing and sealed ability of auxiliary bag after the gasbag is damaged.
Preferably, the end of the filling channel remote from the auxiliary bladder is provided with a one-way filling valve. The water injection amount of the auxiliary bag is convenient to control.
The utility model discloses an useful part lies in: the air bag has good fit with the urethral orifice in the bladder, and the clamping is stable, so that the air bag catheter is prevented from leaking urine; form bilayer structure through supplementary bag and gasbag, supplementary bag is spacing with the urethra when the gasbag is damaged or reveals, prevents that the catheter from directly deviating from.
