Abstract
The utility model discloses a kind of catheter, belong to medical instruments field, this catheter comprises the air bag being arranged on catheter head and the inflation port being arranged on afterbody, air bag is the multiple ballonets arranged along body one section distribution and around body, and after inflation/topping up, ballonet external diameter is greater than catheter external diameter.The air bag of inflation topping up plays fixing catheter, and rear gasbag of bleeding, without protrusion, effectively can reduce tube drawing resistance and the damage to mucous membrane of urethra, thus alleviate the misery of patient.
Description
Technical field
This utility model belongs to medical mechanical domain, specifically be a kind of catheter.
Background technology
After catheter per urethra inserts bladder, inflate in the air bag near catheter head end, the air bag of expansion can make catheter be fixed on intravesical, not easily deviates from, thus reaches the object connecting urinal collection urine.The head end of the catheter of current use is an air vesicle structure, and when extracting catheter, even if extract out to greatest extent the gas in air bag, expanded air bag still can larger projection, cannot return to initial shape completely.Protruding air bag causes in tube drawing process and occurs pain, later stage dysuria, brings certain misery to patient.
Utility model content
Technical problem to be solved in the utility model is when catheter needs to extract, the air bag of fixing catheter bleeds/drawing liquid after exist large protruding, cause tube drawing smooth, cause pain and later stage dysuric problem.
This utility model solves the technical scheme that its technical problem adopts: a kind of catheter, comprise the air bag being arranged on catheter head and the inflation port being arranged on afterbody, described air bag is the multiple ballonets arranged along body one section distribution and around body, and after inflation/topping up, ballonet external diameter is greater than catheter external diameter.
Further, the original state of ballonet is to pipe sunken inside.
This utility model changes traditional catheter head end air vesicle structure into some ballonet structure, and some ballonets can reach the object of fixing catheter under less inflation/topping up distortion, and after bleeding when tube drawing, it is without protruding, and can effectively reduce tube drawing resistance.As optimizing structure the original state of ballonet is designed to pipe sunken inside structure, although during tube drawing air bag place cannot return to insufflation gas before duplicate state, at least can return to compared with other position external diameters of body without any projection.Greatly reduce the resistance of tube drawing and the damage to mucous membrane of urethra like this, thus alleviate the misery of patient.

Below in conjunction with drawings and Examples, this utility model is further illustrated.

Detailed description of the invention
Catheter of the present utility model, comprise the air bag 1 being arranged on catheter head and the inflation port 2 being arranged on afterbody, air bag 1 is the multiple ballonets arranged along body one section distribution and around body, and after inflation/topping up, ballonet external diameter is greater than catheter external diameter.
When catheter is inserted urethra, air bag 1 is in original state (as depicted in figs. 1 and 2), by inflation port 2 to insufflation gas or liquid in air bag 1, what air bag 1 became expands (as shown in Figure 3 and Figure 4), then by catheter, slowly tractive is to meeting resistance outward, and now explanation air bag 1 plays fixation.During tube drawing, by inflation port 2 place, the gas/liquid in air bag is extracted out, air bag retraction (as shown in Figure 5 and Figure 6).In the present embodiment, air bag 1 original state is to pipe sunken inside, although air bag 1 is difficult to the original state returning to Fig. 1 during tube drawing, now tube drawing also has no resistance.
Claims (2)
1. a catheter, comprise the air bag being arranged on catheter head and the inflation port being arranged on afterbody, it is characterized in that: described air bag is the multiple ballonets arranged along body one section distribution and around body, and after inflation/topping up, ballonet external diameter is greater than catheter external diameter.
2. catheter according to claim 1, is characterized in that: the original state of ballonet is to pipe sunken inside.
