Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a drainage fluid collection bag. Background Art

[0002] In the clinical care of digestive tract tumors, patients often experience symptoms such as excessive ascites and abdominal distension. Clinicians often place an indwelling abdominal drainage tube to drain the ascites and alleviate the patient's abdominal distension, thereby relieving the patient's discomfort. However, due to the poor nutritional status of patients in the late stages of cancer and poor healing of the tissue surrounding the puncture site, the indwelling abdominal drainage tube cannot be wrapped by the surrounding tissue. Furthermore, the patient has excessive ascites and high abdominal pressure, which can easily lead to fluid leakage around the abdominal drainage tube.

[0003] After searching, the Chinese patent authorization number CN115998969A discloses a drainage tube exudate collection bag, which collects ascites exuded around the abdominal drainage tube by fixing the drainage fluid collection bag on the skin around the puncture point.

[0004] The above patent also has the following shortcomings: the adhesive portion does not conform to the abdominal curve of the human body, and after being fixed on the human skin, it will restrict human activities and is prone to falling off. Utility Model Content

[0005] The purpose of the utility model is to provide a drainage fluid collection bag, wherein the adhesive portion is arranged according to the curve of the human abdomen so that the adhesive portion can fit the human abdomen and improve the adhesion stability between the drainage fluid collection bag and the human skin.

[0006] In a first aspect, the utility model provides a drainage fluid collection bag, comprising:

[0007] The bag body is provided with a liquid storage cavity and a drainage port, wherein the drainage port is used for inserting a drainage tube into the liquid storage cavity;

[0008] An adhesive portion is provided on the bag body, the adhesive portion is provided in an elliptical shape, and the drainage port is provided at the origin of the adhesive portion;

[0009] A liquid outlet pipe is communicated with the liquid storage cavity and is used to discharge the drainage liquid in the liquid storage cavity to the outside. The length extension direction of the liquid outlet pipe is parallel to the width extension direction of the adhesive portion.

[0010] The drainage fluid collection bag provided by the utility model has the length direction of the adhesive portion aligned horizontally with the human abdomen, and the width direction of the adhesive portion aligned vertically with the human abdomen when being fixed to the human skin, which helps to reduce the restriction of the adhesive portion on human activities and enhances the adhesion stability of the drainage fluid collection bag to the human skin.

[0011] Furthermore, the adhesive portion includes a first adhesive portion and a second adhesive portion, the drainage port is provided on the first adhesive portion, and the second adhesive portion is spaced around the first adhesive portion.

[0012] By adopting the above technical solution, by setting the first adhesive part and the second adhesive part, the corresponding adhesive part can be selected for fixation according to the size of the patient's abdomen, which helps to improve the fit between the adhesive part and the patient's abdomen.

[0013] Furthermore, the number of the second adhesive portions is at least two, the second adhesive portions are all arranged in an elliptical ring shape, the second adhesive portions are arranged at intervals along the circumference of the first adhesive portion, and the circumference of the second adhesive portions is arranged to increase from close to the drainage port to away from the drainage port.

[0014] Furthermore, the adhesive portion includes an adhesive layer and an oil paper layer, the adhesive layer is used to be adhered to the patient's skin, and the oil paper layer is detachably arranged on a side of the adhesive layer facing away from the bag body.

[0015] Furthermore, the bag body is further provided with a cleaning port, and the cleaning port and the drainage port are arranged on opposite sides of the bag body.

[0016] By adopting the above technical solution, there is no need to remove the entire drainage fluid collection bag, and the puncture port can be cleaned through the cleaning port, which is convenient for cleaning.

[0017] Furthermore, the bag body is provided with a third adhesive portion, which is arranged around the cleaning port and is used for adhering a sealing film.

[0018] By adopting the above technical solution, a third adhesive portion is provided for sticking the sealing film, which can reduce the odor of the drainage fluid from flowing out through the cleaning port when not cleaning; when cleaning is required, only the sealing film needs to be removed, which is convenient to use.

[0019] Furthermore, the distance from the cleaning port to the liquid outlet pipe is greater than the distance from the drainage port to the liquid outlet pipe.

[0020] Furthermore, it also includes a tube body, a plug body and a connecting block, and there are multiple connecting blocks. One end of the multiple connecting blocks is arranged on the inner wall of the tube body, and the other end is arranged on the outer wall of the plug body. The liquid outlet pipe can be inserted into the tube body so that the plug body closes the liquid outlet pipe.

[0021] By adopting the above technical solution, by inserting the liquid outlet tube into the tube body, the plug in the tube body can be extended into the liquid outlet tube for sealing, which helps to reduce the occurrence of drainage liquid accidentally flowing out of the liquid storage cavity through the liquid outlet tube.

[0022] Furthermore, a first limiting ring is provided on the outside of the liquid outlet tube, and a second limiting ring is provided on the inside of the tube body. The tube body can expand circumferentially until the inner diameter of the second limiting ring is larger than the outer diameter of the first limiting ring, so that the liquid outlet tube can be inserted into the tube body; the tube body can also shrink circumferentially until the inner diameter of the second limiting ring is smaller than the outer diameter of the first limiting ring, so as to limit the liquid outlet tube from separating from the tube body.

[0023] Furthermore, at least one end of the first limiting ring is provided with a rounded edge; and / or at least one end of the second limiting ring is provided with a rounded edge.

[0024] By adopting the above-mentioned technical solution, by setting rounded edges on the first limiting ring and the second limiting ring, when the first limiting ring and the second limiting ring approach each other, the rounded edges with linearly changing circumference can cause the tube body to gradually expand, which helps to reduce the occurrence of the first limiting ring and the second limiting ring being crushed.

[0025] As can be seen from the above, the drainage fluid collection bag provided by the present invention has an elliptical adhesive portion. Since the lateral deformation of the abdominal skin is much smaller than the vertical deformation when the human body moves, when fixing it to the human skin, by aligning the length direction of the adhesive portion with the horizontal direction of the human abdomen, it helps to enhance the adhesion stability of the adhesive portion to the human skin; by aligning the width direction of the adhesive portion with the vertical direction of the human abdomen, it helps to reduce the restriction of the adhesive portion on human activities.

[0026] Other features and advantages of the present application will be described in the following description, and in part will become apparent from the description, or understood by practicing the embodiments of the present application.

[0044] In one embodiment, the adhesive portion 200 includes an adhesive layer and an oil paper layer. The adhesive layer is used to adhere to the patient's skin, and the oil paper layer is detachably arranged on the side of the adhesive layer facing away from the bag body 100.

[0045] Specifically, when not in use, the oil paper layer keeps covering the adhesive layer, thereby maintaining the stickiness of the adhesive layer; when in use, the adhesive layer can be fixed to the patient's skin by simply removing the oil paper layer.

[0046] Reference Attachment Figure 3 In one embodiment, the bag body 100 is further provided with a cleaning port 130 , and the cleaning port 130 and the drainage port 120 are provided on opposite sides of the bag body 100 .

[0047] Specifically, the diameter of the cleaning port 130 may be 2 cm.

[0048] By adopting the above technical solution, there is no need to remove the entire drainage fluid collection bag, and the puncture port can be cleaned through the cleaning port 130, which is convenient for cleaning.

[0049] In one embodiment, the bag body 100 is further provided with a third adhesive portion 131 . The third adhesive portion 131 is provided around the cleaning opening 130 and is used for adhering a sealing film.

[0050] Specifically, the sealing film may be a transparent plastic film.

[0051] By adopting the above technical solution, by setting the third adhesive portion 131 for sticking the sealing film, the odor of the drainage fluid can be reduced from flowing out through the cleaning port when not cleaning; when cleaning is required, only the sealing film needs to be removed, which is convenient to use.

[0052] In one embodiment, the distance from the cleaning port 130 to the liquid outlet pipe 300 is greater than the distance from the drainage port 120 to the liquid outlet pipe 300 .

[0053] Specifically, the distance difference between the cleaning port 130 and the drainage port 120 may be 1 cm.

[0054] Reference Attachment Figure 4 , Attachment Figure 5 , Attachment Figure 6 In one embodiment, it also includes a tube body 410, a plug body 420 and a connecting block 430. There are multiple connecting blocks 430, one end of each connecting block 430 is arranged on the inner wall of the tube body 410, and the other end is arranged on the outer wall of the plug body 420. The liquid outlet pipe 300 can be inserted into the tube body 410 so that the plug body 420 closes the liquid outlet pipe 300.

[0055] By adopting the above technical solution, by inserting the liquid outlet tube 300 into the tube body 410, the plug body 420 in the tube body 410 can be extended into the liquid outlet tube 300 for sealing, which helps to reduce the occurrence of drainage liquid accidentally flowing out of the liquid storage cavity 110 through the liquid outlet tube.

[0056] In one embodiment, a first limiting ring 310 is provided on the outside of the liquid outlet tube 300, and a second limiting ring 411 is provided on the inside of the tube body 410. The tube body 410 can expand circumferentially until the inner diameter of the second limiting ring 411 is larger than the outer diameter of the first limiting ring 310, so that the liquid outlet tube 300 can be inserted into the tube body 410; the tube body 410 can also shrink circumferentially until the inner diameter of the second limiting ring 411 is smaller than the outer diameter of the first limiting ring 310, so as to limit the liquid outlet tube 300 from separating from the tube body 410.

[0057] It is worth noting that after the plug body 420 is separated from the liquid outlet tube 300, the liquid outlet tube 300 can still remain inserted into the tube body 410. At this time, the first limiting ring 310 and the second limiting ring 411 are abutted against each other, and the drainage liquid in the liquid storage cavity 110 can flow out to the outside through the gaps between the multiple connecting blocks 430, which is suitable for situations where a small amount of drainage liquid needs to be discharged; when a large amount of drainage liquid needs to be discharged, the tube body 410 and the liquid outlet tube 300 can be completely separated.

[0058] In one embodiment, at least one end of the first limiting ring 310 is provided with a rounded edge; and / or at least one end of the second limiting ring 411 is provided with a rounded edge.

[0059] By adopting the above technical solution, by setting rounded edges on the first limiting ring 310 and the second limiting ring 411, when the first limiting ring 310 and the second limiting ring 411 approach each other, the rounded edges with linearly changing circumference can cause the tube body 410 to gradually expand, which helps to reduce the occurrence of the first limiting ring 310 and the second limiting ring 411 being crushed.
