Description

Technical Field

[0001] The utility model relates to the technical field of drainage bags, and particularly relates to a drainage bag. Background Art

[0002] The drainage bags used clinically are mainly used to collect and store urine for patients with urinary incontinence, coma, paralysis, concussion, stroke, and after surgery, and can also be used for the elderly with urinary incontinence; many critically ill patients in the hospital are unable to get up and urinate by themselves. Especially some special surgical patients and some emergency patients in the ICU are unable to urinate by themselves. After these patients are hospitalized and bedridden, in order to reduce the workload of nurses, urinary catheters will be inserted and drainage bags will be hung.

[0003] At present, when a patient wears a mother-and-son drainage bag for treatment, the patient's urine and tissue flow into the mother-and-son drainage bag through a catheter for storage. However, the tissue is likely to cause blockage at the inlet of the catheter and the mother-and-son drainage bag during the flow into the mother-and-son drainage bag. After the pipeline is blocked, it is necessary to replace the mother-and-son drainage bag for treatment again. This situation greatly affects the treatment effect of the patient and increases the pain of the patient. Moreover, if the mother-and-son drainage bag needs to be replaced again just after replacement, it not only wastes resources but also increases the workload of medical staff. Therefore, this device provides a drainage bag. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a drainage bag for the deficiencies of the prior art to solve the above-mentioned technical problems.

[0005] The embodiment of the utility model adopts the following technical scheme: It includes a drainage bag for storing the patient's urine, a catheter, and a filtering device. The inlet of the drainage bag is connected to the catheter through the filtering device. The head end of the catheter is connected to the treatment position required by the patient. The filtering device is located at the inlet of the drainage bag and functions to filter the urine impurities inside the catheter. The drainage bag is a mother-and-son drainage bag. The inlet of the mother-and-son drainage bag is connected to the filtering device by a bolt connection method. The catheter is also fixed to the filtering device by a bolt connection method and is connected in communication.

[0006] Further, the filtering device includes a connection cap, a holding ring, a filtering tube, and a filter net. The inlet of the mother-and-son drainage bag is provided with an external thread. The inside of the connection cap is provided with an internal thread adapted to the external thread at the inlet of the mother-and-son drainage bag. The lower end of the filtering tube extends into it through the inlet of the mother-and-son drainage bag. The connection cap is located outside the filtering tube and is rotatably connected. The filter net is located inside the lower end of the filtering tube. The holding ring is arranged outside the filtering tube. The outside of the upper end of the filtering tube is provided with an external thread.

[0007] Further, the filter net is conical.

[0008] Furthermore, a fixing cap is rotatably arranged on the catheter. The inner part of the fixing cap is provided with an internal thread adapted to the external thread on the upper end of the filter tube. The fixing cap has the same structure and size as the connecting cap, and the internal thread inside the fixing cap is in an adapted state with the external thread at the inlet of the mother and child drainage bag.

[0009] Furthermore, the mother and child drainage bag is made of transparent plastic material, and scale values are provided on the mother and child drainage bag.

[0010] Furthermore, two hooks are symmetrically arranged at the upper end of the mother and child drainage bag.

[0011] The above at least one technical solution adopted in the embodiment of the present invention can achieve the following beneficial effects:

[0012] In the present invention, when a patient wears the mother and child drainage bag for treatment, the patient's urine and fine tissues flow into the mother and child drainage bag through the catheter for storage. And when the tissues flow into the mother and child drainage bag, the filter device can block the tissues. When it is necessary to replace the filter device when the tissues accumulate more, the medical staff first rotate the fixing cap to separate the fixing cap on the catheter from the upper end of the filter tube. Then, rotate the connecting cap to separate the fixing cap on the filter tube from the inlet of the mother and child drainage bag. Then, the medical staff holds it on the placing and taking ring, places the lower end of the filter tube in the new filter device into the inlet of the mother and child drainage bag, then rotates the connecting cap for the required fixation and connection, and then rotates the fixing cap to connect and communicate with the upper end of the filter tube. The whole observation is relatively convenient and has no difficulty at all. It not only does not affect the treatment effect of the patient, but also avoids the pain of the patient. At the same time, the cost is low and the operation is convenient, greatly reducing the workload of the medical staff, so it is convenient for wide use;

[0013] During the treatment of the patient, if, according to the judgment of the medical staff, the tissues of the patient will not cause the blockage of the inlet of the mother and child drainage bag and make it unusable, the filter device can be omitted, and only the fixing cap on the catheter needs to be rotated to be fixedly connected with the inlet of the mother and child drainage bag;

[0014] Since the tissues generally flow with the liquid flow, and the filter net is conically arranged, the filter holes on the filter net are in an inclined state at this time, so as to reduce the probability of the tissues flowing into the filter holes, thereby improving the service life of the filter device.

[0024] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the specific embodiments of the present utility model and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present utility model.

[0025] The technical solutions provided by the embodiments of the present utility model will be described in detail below with reference to the drawings.

[0026] An embodiment of the present utility model provides a drainage bag, which includes a drainage bag 1 for storing urine of a patient, a catheter 2 and a filtering device 3. The catheter 2 is connected and communicated through the filtering device 3 at the inlet 11 of the drainage bag 1. The head end of the catheter 2 is connected to the treatment position required by the patient. The filtering device 3 is located at the inlet 11 of the drainage bag 1 to filter the urine impurities inside the catheter 2. The drainage bag 1 is a mother - and - son drainage bag 1. The inlet 11 of the mother - and - son drainage bag 1 is connected to the filtering device 3 by a bolt connection method. The catheter 2 is also fixed to the filtering device 3 by a bolt connection method and is connected and communicated;

[0027] When the patient wears the parent-child drainage bag 1 for treatment, the patient's urine and fine tissue substances flow into the parent-child drainage bag 1 through the catheter 2 for storage. During the process of flowing into the parent-child drainage bag 1, the tissue substances can be blocked by the filtering device 3. And when there is a large accumulation of tissue substances, only the filtering device 3 needs to be replaced, which not only does not affect the treatment effect of the patient, but also avoids the pain of the patient. At the same time, the cost is low and the operation is convenient, greatly reducing the workload of medical staff, thus facilitating wide use.

[0028] In a further preferred embodiment of the present utility model, the filtering device 3 includes a connecting cap 31, a holding ring 32, a filtering tube 33 and a filtering net 34. An external thread is provided at the inlet 11 of the parent-child drainage bag 1. An internal thread adapted to the external thread at the inlet 11 of the parent-child drainage bag 1 is provided inside the connecting cap 31. The lower end of the filtering tube 33 extends into it through the inlet 11 of the parent-child drainage bag 1. The connecting cap 31 is located outside the filtering tube 33 and is rotatably connected. The filtering net 34 is located inside the lower end of the filtering tube 33. The holding ring 32 is arranged outside the filtering tube 33. An external thread is provided outside the upper end of the filtering tube 33. A fixing cap 21 is rotatably arranged on the catheter 2. An internal thread adapted to the external thread outside the upper end of the filtering tube 33 is provided inside the fixing cap 21. The fixing cap 21 has the same structure and size as the connecting cap 31. The internal thread inside the fixing cap 21 is in an adapted state with the external thread at the inlet 11 of the parent-child drainage bag 1.

[0029] When the patient wears the parent-child drainage bag 1 for treatment, the patient's urine and fine tissue substances flow into the parent-child drainage bag 1 through the catheter 2 for storage. During the process of flowing into the parent-child drainage bag 1, the tissue substances can be blocked by the filtering device 3. When it is necessary to replace the filtering device 3 when there is a large accumulation of tissue substances, the medical staff first rotate the fixing cap 21 so that the fixing cap 21 on the catheter 2 is separated from the upper end of the filtering tube 33. Then, rotate the connecting cap 31 so that the fixing cap 21 on the filtering tube 33 is separated from the inlet 11 of the parent-child drainage bag 1. Then, the medical staff hold the holding ring 32 and take out the entire filtering device 3 and place it at the required position. Through the holding ring 32, the medical staff can avoid contacting the urine inside the filtering net and the filtering tube. Place the lower end of the filtering tube 33 in the new filtering device 3 inside the inlet 11 of the parent-child drainage bag 1, and then rotate the connecting cap 31 to the required position for fixing and connecting. Then rotate the fixing cap 21 to connect and communicate with the upper end of the filtering tube 33. The whole observation is more convenient and has no difficulty at all. It not only does not affect the treatment effect of the patient, but also avoids the pain of the patient. At the same time, the cost is low and the operation is convenient, greatly reducing the workload of medical staff, thus facilitating wide use.

[0030] During the treatment of a patient, if, according to the judgment of medical staff, the patient's tissue will not cause blockage at the inlet 11 of the mother-child drainage bag 1 and render it unusable, there is no need to follow the filtering device 3. Instead, only the fixing cap 21 on the catheter 2 needs to be rotated and fixed in communication with the inlet 11 of the mother-child drainage bag 1.

[0031] In a further preferred embodiment of the present utility model, the filter net 34 is conically arranged.

[0032] Since tissue generally flows along with the liquid flow, and the filter net 34 is conically arranged, the filter holes on the filter net 34 are in an inclined state at this time, thereby reducing the probability of tissue flowing into the filter holes and improving the service life of the filtering device 3.

[0033] In a further preferred embodiment of the present utility model, the mother-child drainage bag 1 is made of transparent plastic material, and a scale value 13 is provided on the mother-child drainage bag 1.

[0034] With the mother-child drainage bag 1 made of transparent plastic material and a scale value 13 provided on the mother-child drainage bag 1, it is convenient for personnel to check the required liquid volume and the liquid condition.

[0035] In a further preferred embodiment of the present utility model, two hooks 12 are symmetrically provided at the upper end of the mother-child drainage bag 1.

[0036] With two hooks 12 symmetrically provided at the upper end of the mother-child drainage bag 1, it is convenient to hang the mother-child drainage bag 1 at the required position for use.

[0037] The above are only the embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, various modifications and changes can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the scope of the claims of the present utility model.
