Description

Technical Field

[0001] The utility model belongs to the field of medical devices, and particularly relates to a drainage bag capable of accommodating a drainage tube. Background Technique

[0002] Drainage technology is one of the basic technologies widely used in clinical practice. Inserting a drainage tube can achieve good therapeutic effects on common surgical diseases such as abdominal effusion, infectious suppuration, and pleural effusion caused by liquefaction necrosis of tissues. Most surgical operations require the placement of a drainage tube, and with the continuous development of medical technology, the application of drainage tubes in clinical practice is becoming more and more extensive. It can be used not only in non-invasive drainage (such as indwelling catheterization, gastrointestinal decompression, etc.), but also in invasive drainage (such as abdominal drainage, biliary drainage, etc.). Many patients need to indwell the drainage tube at home after surgery. For example, in the early stage after cerebral hemorrhage surgery, indwelling a urinary catheter is required to prevent the occurrence of neurogenic urinary retention. Since patients after cerebral hemorrhage surgery have severe nerve function damage, a long course of disease, and slow recovery, even after the condition is stable during the acute-phase hospitalization, there are still patients who cannot have the tube removed and need to be discharged home with the tube for recuperation.

[0003] Indwelling the drainage tube after surgery restricts the patient's activities to varying degrees and affects the patient's comfort. Generally, a surplus is set when configuring the drainage tube. For patients, the redundant part of the drainage tube in the external extended part is prone to adverse events such as tube slippage, kinking, and blockage, which have a negative impact on the patient's recovery.

[0030] In this embodiment, the material of the plastic skeleton 1 is PE plastic, and the connection area 3 and the liquid collection area 4 form a sealed chamber through the hot-melt PVC material, so that the liquid collection area 4 can hold the drained liquid. A drain pipe 5 is connected to the liquid collection area 4, and a regulating valve 51 is arranged on the drain pipe 5. When the liquid level in the liquid collection area 4 is relatively high, the liquid in the liquid collection area 4 can be released by opening the regulating valve 51 on the drain pipe 5.

[0031] Embodiment Two:

[0032] Based on Embodiment One, this embodiment provides an alternative solution for the specific structure of the storage area.

[0033] In this embodiment, an openable and closable PVC diaphragm 21 is arranged on one side of the storage area 2. A through hole 23 is opened on the top wall of the storage area 2, and the drainage tube at the patient end passes through the through hole 23 and is connected to the connection area 3. A number of second snap buttons 22 are arranged on the PVC diaphragm 21, and the second snap buttons 22 are buckled with the snap buttons on the side wall of the storage area 2. The drainage tube at the through hole 23 is buckled between two adjacent second snap buttons 22, so as to clamp the drainage tube between the rear side wall of the storage area 2 and the PVC diaphragm 21. When the second snap buttons 22 on the PVC diaphragm 21 are buckled with the snap buttons on the side wall of the storage area 2, the drainage tube at the through hole 23 is buckled between two adjacent second snap buttons 22, thereby fixing the drainage tube, which can effectively prevent the drainage tube from detaching from the storage area; when it is necessary to store or pull the drainage tube, just unfasten the cooperation of the second snap buttons 22, and the operation is simple and convenient for patients of all age groups to operate.

[0034] Figures 1 to 3 Only the case where the plastic skeleton 1 is only provided with one through hole 23 is shown, and the number of through holes 23 on the plastic skeleton 1 can be flexibly set according to the number of drainage tubes, so that each drainage tube at the patient end passes through the through hole 23.

[0035] In this embodiment, the cross-sectional area of the through hole 23 is semi-circular. The semi-circular through hole can effectively prevent the drainage tube from swinging left and right in the through hole 23.

[0036] In a possible embodiment, the front and rear side walls of the storage area 2 are through, and PVC diaphragms 21 are arranged on both the front and rear sides of the storage area 2. The second snap buttons 22 on the PVC diaphragms 21 on the front and rear sides of the storage area 2 are buckled with each other, so as to clamp the drainage tube between the two PVC diaphragms 21.

[0037] In another possible embodiment, as Figure 5 shown, the front part of the storage area 2 is sealed, and the PVC diaphragm 21 is arranged in the area of the storage area 2 close to the through hole 23. In this embodiment, the movable area of the storage area 2 is smaller, which has a better limiting effect on the soft drainage tube curled in the storage area 2.

[0038] Embodiment III:

[0039] On the basis of any of the above embodiments, this embodiment provides an alternative solution for the specific structure of the connection area.

[0040] In this embodiment, a drainage channel 31 is provided in the connection area 3. The drainage channel 31 is used to connect the storage area 2 and the liquid collection area 4. A first one-way valve 25 and a second one-way valve 32 are respectively arranged at both ends of the drainage channel 31. A tower joint 24 is arranged in the storage area 2. The first one-way valve 25 is arranged between the tower joint 24 and the drainage channel 31. The tower joint 24 is used for quickly connecting with the drainage tube. Both the first one-way valve 25 and the second one-way valve 32 at both ends of the drainage channel 31 only allow the fluid to enter the liquid collection area 4 from the drainage tube unidirectionally, which can ensure the flow direction of the liquid in the drainage tube, effectively prevent the liquid from flowing back, and thus reduce the incidence of retrograde infection.

[0041] Figures 1 to 3 Only the case where one drainage channel 31 is provided in the connection area 3 is shown. When multiple drainage tubes are involved in draining liquid to the liquid collection area 4 at the same time, multiple drainage channels 31 can be provided in the connection area 3. Each drainage channel 31 is connected to the drainage tube in one-to-one correspondence, so as to realize the situation of simultaneously draining the accumulated liquid in multiple parts of the patient's body.

[0042] Embodiment IV:

[0043] On the basis of any of the above, this embodiment provides a fixing structure for the present utility model.

[0044] In this embodiment, as Figures 1 to 4 shown.

[0045] The drainage bag further includes a decorative layer 7. The decorative layer 7 can be detachably connected to both the front and back sides of the plastic skeleton 1. The decorative layer 7 is a cotton cloth with decorative patterns. A number of third snap buttons 71 are arranged on the decorative layer 7, and a number of first snap buttons 11 are arranged on the plastic skeleton 1. The third snap buttons 71 are snapped with the first snap buttons 11 to fix the decorative layer 7 on the plastic skeleton 1. Since it is necessary to observe the liquid level in the liquid collection area, both sides of the drainage bag are made of transparent PVC material. Usually, it can be fixed by the third snap buttons 71 and covered on both sides of the plastic skeleton 1. After removing the cotton cloth on one side, the drainage tube and the liquid level of the drainage liquid can be observed. The outer cotton cloth wraps the transparent chamber in all directions, making the appearance of the drainage bag a common leg bandage bag, similar to a portable small bag for outdoor activities, making the bag body popular.

[0046] At the same time, a detachable tie 12 is arranged at the top of the plastic skeleton 1. When it is necessary to hang the drainage bag, the detachable tie 12 can be sleeved in the notch at the top of the plastic skeleton 1. At this time, the whole drainage bag can be hung through the detachable tie 12.

[0047] Due to the need for drainage, the drainage bag should always be lower than the drainage wound plane. The present utility model is also provided with an elastic band so as to be able to bind the plastic skeleton 1 to the thigh of the patient, which can be lower than most of the drainage wound planes, can meet the drainage requirements, avoid unsmooth drainage and backflow of the drainage fluid, and reduce the incidence of retrograde infection.

[0048] Specifically, a fixing band 13 is provided at the rear side of the plastic skeleton 1, the elastic band 6 passes through the fixing band 13, and magic tapes 61 are provided on both sides of the elastic band 6.

[0049] In some other embodiments, the two ends of the elastic band 6 can also be structures such as buckles, loop hooks, pull hooks, etc. that can connect the two ends of the elastic band 6 together.

[0050] Before the present utility model is used, the patient should check that the regulating valve 51 is in the closed position, open all the third snap fasteners 71, and remove the outer decorative layer 7 of the drainage bag.

[0051] When in use, the patient needs to open the second snap fastener 22, fully unfold the storage area 2, connect the patient-side drainage tube interface with the tower joint 24 and fully tighten it. According to the height difference between the patient's drainage wound plane and the thigh, the length of the patient-side drainage tube, etc., place the drainage tube of an appropriate length properly in the storage area 2, and pass the drainage tube at the entrance of the storage area 2 through the through hole 23, and close the second snap fastener 22. Thereafter, the patient can connect the cotton cloth to both sides of the plastic skeleton 1 through the third snap fastener 71. After confirming that the connection is firm, fully unfold the elastic band 6, connect the two ends of the elastic band 6 together through the magic tape 61, select a suitable position and bind it to the leg; repeat the above operation to fix the other elastic band 6. Finally, the patient should readjust the storage length of the patient-side drainage tube and the fixing position of the drainage bag again in the upright position. If the patient wears clothing such as a belt that can be used for fixation, the detachable tie 12 can also be tied to the belt for fixation.

[0052] The drainage fluid enters from the drainage tube at the patient side, passes through the tower joint 24 and the first one-way valve 24 in the storage area 2 and flows into the drainage channel 31 in the connection area 3, and then flows into the liquid collection area 4 through the second one-way valve 32 at the other end of the drainage channel 31. The patient can roughly measure the amount of the drainage fluid through the identifier 41 on one side of the liquid collection area 4.

[0053] When draining the liquid, the patient needs to open all the third snap fasteners 71, remove the outer decorative layer 7 of the drainage band, open the regulating valve 51. After the liquid is emptied, gently squeeze the liquid collection area 4 to discharge the air. After the drainage is completed, the patient should close the regulating valve 5, connect the decorative layer 7 to the plastic skeleton 1 through the third snap fastener 71, and confirm that the connection is firm. During the drainage process, there is no need to untie the elastic band 6.
