Description

Technical Field

[0001] The utility model relates to a nursing appliance for medical environment, in particular to an anti-reflux drainage bag. Background Technique

[0002] In clinical work, due to the need of disease treatment, various drainage tubes (urinary catheter, thoracic drainage tube, pericardial drainage tube, abdominal drainage tube, etc.) need to be placed on the patient for drainage treatment of body fluid accumulation. The drained body fluid needs to be temporarily collected and stored using a drainage bag. Therefore, the drainage bag is a common nursing appliance in clinical treatment.

[0003] The existing drainage bag for drainage consists of a drainage tube, a drainage bag and a drainage pipe. In long-term use, it is found that the existing drainage bag only relies on the buckle on the drainage tube to achieve the anti-reflux function. When the patient changes body position, forgets to close the buckle or uses it improperly, the drained body fluid may flow back, which is not conducive to treatment.

[0004] Currently, anti-reflux drainage devices are also used for drainage treatment in clinical practice. For example, the technology with the name of "anti-reflux drainer", publication number CN2507464Y and publication date August 28, 2002 disclosed in the Chinese patent literature. The above technical measures add a drip kettle to the drainage tube to slow down the liquid flow rate. Although the speed of backflow is reduced to a certain extent, the drip kettle does not have the function of preventing backflow, and backflow still exists. Moreover, the drip kettle slows down the flow rate of the drained liquid, which is not conducive to clinical drainage treatment and needs to be improved. Content of the Utility Model

[0005] The technical object of the utility model is to provide an anti-reflux drainage bag that does not interfere with treatment and has a good anti-reflux effect in view of the particularity of clinical drainage treatment and the deficiencies of the existing technology.

[0006] The technical object of the utility model is achieved by the following technical solution: an anti-reflux drainage bag, comprising a drainage bag body;

[0007] The upper part of the drainage bag body is connected with a drainage tube, and the lower part is connected with a drainage pipe. The upstream end of the drainage tube is used for being placed on the patient, and the drainage pipe is connected with a drainage valve;

[0008] The downstream end of the drainage tube extends into the drainage bag body, and an anti-reflux structure is connected in the drainage bag body at the downstream end of the drainage tube;

[0009] The anti-reflux structure is a flexible film structure covering the downstream end of the drainage tube. The flexible film below the downstream end of the drainage tube forms an adsorption fit with the drainage bag body or the relative flexible film under the action of liquid adhesion.

[0010] The drainage bag of the above technical measures is provided with an anti-backflow structure. During drainage treatment, the flexible film below the downstream end of the drainage tube forms an adsorption cooperation with each other or the bag wall under the action of liquid adhesion, so that the liquid can only enter but not exit. It has a good anti-backflow effect without affecting the drainage treatment.

[0011] The drainage bag body is used as a part for inserting the drainage tube, and is sealed and connected to a supporting base plate with a hard structure;

[0012] The lower part of the support base plate is sealed and connected to the drainage bag body, the upper part of the support base plate extends out of the drainage bag body, and a limiting ring capable of passing a drainage tube is formed on one side of the portion where the support base plate extends out of the drainage bag body;

[0013] The downstream end of the drainage tube passes through the limiting ring on the supporting base plate and extends into the drainage bag body in a sealed manner.

[0014] The drainage tube of the above technical measures is inserted into the drainage bag through a limiting ring on a supporting base plate of a hard structure that is sealed and connected to the drainage bag. The limiting ring on the supporting base plate limits and fixes the drainage tube, and the hard supporting base plate supports the soft drainage bag, making it convenient for staff to take / operate.

[0015] The support base plate is formed with a hinge seat convexly on the side opposite to the limiting ring;

[0016] The hinge seat is hinged with an epitaxially formed bending structure hook.

[0017] The support base plate of the above technical measure is hinged with a hook with a bent structure through a hinge shaft on the side facing away from the limiting ring. During drainage treatment, the hook can fix the drainage bag hook on the armrests on both sides of the bed, which is simple to operate and easy to use.

[0018] The sealed connection between the drainage bag body and the support base plate is provided with two rope threading holes at both ends of the support base plate;

[0019] A knottable connecting rope is inserted into the rope threading hole.

[0020] The drainage bag support base plate of the above technical measures has rope threading holes at both ends for threading the connecting rope. The connecting rope can be used to reinforce the connection between the drainage bag and the bed armrest on the one hand, and can be used to store the excess length of the drainage tube on the other hand.

[0021] The drainage tube is connected with a buckle;

[0022] The buckle is used to control the drainage tube on / off.

[0023] The drainage tube connected to the drainage bag of the above technical measures is also provided with a buckle, which is used to control the on / off of the drainage tube, further increasing the anti-backflow performance of the drainage bag, and having good anti-backflow performance.

[0024] The upstream end of the drainage tube has a through hole;

[0025] The through hole position is a one-way structure matching the needle receiving post of the handheld syringe.

[0026] The upstream section of the drainage tube of the above technical measures has a through hole, and the position of the through hole matches the needle receiving hole of the syringe. When the drainage tube is blocked by body tissues during drainage treatment, there is no need to disassemble and separate the drainage tube from the drainage bag, and the drainage tube can be directly dredged through the through hole, with simple operation.

[0027] The drainage bag body has a belly-expanding structure with a circular bottom expanding outward on a plane, and a drain pipe is hermetically connected to the bottom center of the belly-expanding structure through a convex structure that gradually extends downward;

[0028] Along the height direction of the drainage bag body, a first measurement scale is formed on one side wall of the drainage bag body. This technical measure facilitates medical staff to observe the drainage process and results of a large volume in the drainage bag.

[0029] At the belly-expanding structure of the drainage bag body, an obliquely arranged second measurement scale is formed on one side wall of the drainage bag body;

[0030] The height direction of the second measurement scale corresponds to the bottom of the belly-expanding structure of the drainage bag body;

[0031] The measured value of the second measurement scale is less than the measured value of the first measurement scale.

[0032] The above technical measures are also provided with a second measurement scale, which is used for the measurement work during small-volume drainage.

[0033] The beneficial technical effect of the present utility model is that: through the adsorption cooperation of the flexible films below the downstream end of the drainage tube with each other or with the bag wall under the action of liquid adhesion, the present utility model achieves the effect that the liquid only enters and does not exit. While not affecting the drainage treatment, it has a good anti-backflow effect, which is beneficial to clinical treatment. BRIEF DESCRIPTION OF THE DRAWINGS
