TECHNICAL FIELD
[0001] The utility model relates to the technical field of medical collecting bag, specifically is a exudation collecting bag. BACKGROUND
[0002] In various endoscopic surgeries, there are some cases where the patient's body still has some incisions after the operation, such as the incision left after the removal of the drainage tube. At this time, the incision is usually only covered with medical gauze to allow the incision to heal naturally. During this process, the incision will continuously exude blood or tissue fluid and other liquids, and medical staff need to regularly replace the gauze to keep the incision clean. However, the natural healing of the incision is relatively slow, and frequent replacement of the gauze also increases the workload of the medical staff, and there is also a risk of infection of the incision during this process. SUMMARY
[0003] The utility model aims to at least solve one of the technical problems in the related art: to provide an exudate collecting bag that can promote rapid healing of the incision by actively sucking the exudate from the incision and reduce the risk of infection.
[0004] To this end, one object of the utility model is to provide an exudate collecting bag, which comprises a bag body, and the back of the bag body has an exudate collecting port. The utility model is characterized in that: it further comprises a patch, one side of the patch has an adhesive layer, the other side is provided with a connecting piece that is detachably connected with the bag body, and the patch has a through hole for communicating with the exudate collecting port. A negative pressure balloon is provided outside the bag body, and the negative pressure balloon is in communication with the inner cavity of the bag body through a drainage tube.
[0005] The above technical solution has the following advantages or beneficial effects: first, the negative pressure balloon provides a negative pressure suction force on the patient's incision, thereby actively sucking the exudate from the deep part of the patient's incision, thereby helping to promote healing of the incision. Second, the detachable patch and bag body allow the bag body to be regularly detached for cleaning of the bag body and the negative pressure balloon, allowing the bag body to be reused.
[0006] According to one example of the utility model, a drainage tube is provided between the negative pressure balloon and the bag body, one end of the drainage tube is in communication with the negative pressure balloon, the other end extends into the bag body through the bottom of the bag body, and the end of the drainage tube located in the bag body extends to the position of the exudate collecting port. The inner wall of the drainage tube has a plurality of small holes at the position corresponding to the exudate collecting port. The small holes on the drainage tube are directly aligned with the exudate collecting port, thereby directly acting on the patient's incision for negative pressure suction, reducing the probability of not being able to suck due to the bag body being flattened under the negative pressure force and covering the incision, and improving the negative pressure suction effect.
[0007] According to one example of the utility model, the drainage tube and the bag body are of an integrated structure.
[0008] According to an example of the present utility model, the drainage tube is detachably connected with the negative pressure balloon. The detachable negative pressure balloon enables the exudate in the negative pressure balloon to be regularly cleaned.
[0009] According to an example of the present utility model, a drainage port is arranged on the negative pressure balloon. The drainage port on the negative pressure balloon enables the exudate in the negative pressure balloon to be regularly cleaned.
[0010] According to an example of the present utility model, the outer side wall of the drainage tube has a concave liquid passing groove in the bag body, and the small holes are arranged on the liquid passing groove. The liquid passing groove prevents the small holes from being easily blocked when the bag body is compressed and flattened, thereby maintaining the reliability of the negative pressure suction process.
[0011] According to an example of the present utility model, the drainage tube is made of a detachable plastic material. Medical staff can arbitrarily detach and change the pore size of the small holes on the drainage tube according to the differences in patient conditions.
[0012] According to an example of the present utility model, the front surface of the bag body is made of a transparent material. The front surface of the bag body can be used to observe the patient's wound, drainage tube, and small holes on the drainage tube in real time, so that adjustments can be made in time when blockage occurs.
[0013] According to an example of the present utility model, the part of the drainage tube outside the bag body is provided with a switch valve for opening and closing the drainage tube, and the end of the drainage tube inside the bag body has an auxiliary ball with an inner diameter larger than the diameter of the drainage tube.
[0014] Additional aspects and advantages of the present utility model will be partially given in the following description, some will become apparent from the following description, or will be understood through the practice of the present utility model. BRIEF DESCRIPTION OF DRAWINGS

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0021] The exudate collection bag according to an embodiment of the present invention will now be described in detail with reference to the accompanying drawings.
[0022] This utility model provides an exudate collection bag, such as Figure 1 As shown, it includes a bag 1 with an inner cavity, the bag having a front 1.1 and a back 1.2. The back 1.2 of the bag 1 has an exudate collection port 1.3 communicating with the inner cavity of the bag 1. The exudate collection bag also includes a patch 2, one side of which has an adhesive layer that can be attached to the patient's skin, and the other side has a connector 3 that is detachably connected to the bag 1. The connector 3 is fixedly connected to the patch 2. The bag 1 has a connecting component that matches the connector 3, thereby allowing the patch 2 and the bag 1 to be detachably connected through the connector 3 and the connecting component. The patch 2 has a through hole 2.1 for communicating with the exudate collection port 1.3. A negative pressure balloon 4 is provided outside the bag 1, and the negative pressure balloon 4 communicates with the inner cavity of the bag 1 through a drainage tube 5.
[0023] Preferably, the through hole 2.1 has an annular cover sheet that is designed to be cut, thereby making the diameter of the through hole 2.1 adjustable by cutting the cover sheet.
[0024] Specifically, the connector 3 has a ring structure, and the connector 3 is snapped together with the connecting component on the bag body 1. The patch extends into the connector 3 to form a cover.
[0025] The negative pressure balloon 3 is formed by the elastic restoring force of the negative pressure balloon 3 after its internal volume is reduced due to external compression. This gives the negative pressure balloon 3 a negative pressure suction force that draws air into the negative pressure balloon 3.
[0026] Based on the above preferred embodiment, one end of the drainage tube 5 is in communication with the negative pressure balloon 4, and the other end extends into the bag body 1 through the bottom of the bag body 1, and the end of the drainage tube 5 in the bag body 1 extends to the position of the exudate collection port 1.3, and the inner wall of the drainage tube 5 has a plurality of small holes 5.1 at the position corresponding to the exudate collection port 1.3. In this embodiment, the patch 2 is attached to the patient, and the through hole 2.1 on the patch is aligned with the wound of the patient, so that the exudate collection port 1.3 of the bag body 1 is aligned with the wound of the patient, and at this time, due to the negative pressure suction force provided by the negative pressure balloon 3, the small holes 5.1 on the drainage tube 5 are directly close to the wound of the patient, which can better suck out the exudate in the wound of the patient, and the sucked exudate is introduced into the negative pressure balloon 3 through the drainage tube 5.
[0027] Preferably, the drainage tube 5 and the bag body 1 are in an integrated structure. Thus, the risk of liquid leakage at the connection between the drainage tube 5 and the bag body 1 is reduced.
[0028] In order to periodically clean the exudate in the negative pressure balloon 4 and restore the negative pressure suction force of the negative pressure balloon 4, the drainage tube 5 and the negative pressure balloon 4 are preferably detachably connected. After the negative pressure balloon 4 is detached from the drainage tube 5, the negative pressure balloon 4 can be directly cleaned, then the negative pressure balloon 4 is re-flattened, and finally the negative pressure balloon 4 is re-connected with the drainage tube 5.
[0029] In order to periodically clean the exudate in the negative pressure balloon 4 and restore the negative pressure suction force of the negative pressure balloon 4, the negative pressure balloon 4 is preferably provided with a drainage port 4.1. Through the drainage port 4.1, the exudate in the negative pressure balloon 4 can be easily cleaned.
[0030] Preferably, the negative pressure balloon 4 is made of transparent material, and the negative pressure balloon 4 has a scale line.
[0031] In the process of negative pressure suction of exudate from the wound of the patient to promote deep wound healing of the patient, due to the existence of negative pressure, the bag body 1 is in a suction state under the action of negative pressure, that is, the inner side wall of the front surface 1.1 of the bag body 1 is attached to the surface of the wound of the patient, at this time, it is easy to cause the inner side wall of the front surface 1.1 of the bag body 1 to block the small holes 5.1 on the suction tube 5, so that the exudate cannot be sucked out from the small holes 5.1, and in order to facilitate the movement of the patient and reduce the pressure sores caused by the pressure and friction between the bag body 1 and the skin of the patient during wearing, therefore, the bag body 1 can only be made of flexible plastic material. For this reason, the improvement of this embodiment is that: Figure 4As shown, the part of the outer wall of the drainage tube 5 located in the bag body 1 has a concave liquid passage 5.2, and each hole 5.1 is arranged on the liquid passage 5.2. That is, on the basis of the tubular drainage tube 5, the tube wall of the drainage tube 5 is concave to form a concave liquid passage 5.2, the liquid passage 5.2 is strip-shaped, and each hole 5.1 on the drainage tube 5 is arranged on the liquid passage 5.2. Therefore, even if the front surface 1.1 of the bag body 1 covers the drainage tube 5 under the action of negative pressure suction, each hole 5.1 can still be connected through the liquid passage 5.2, and the negative pressure suction can be continuously provided when any position of the liquid passage 5.2 corresponds to the wound of the patient, so that the exudate can flow into the drainage tube 5 from each hole 5.1 through the liquid passage 5.2, and the purpose of continuously negative pressure suction of the exudate is achieved.
[0032] Specifically, the tube wall of the drainage tube 5 is concave radially inward to form an axially extending liquid passage 5.2, and the holes 5.1 are arranged at positions of the liquid passage 5.2 in an axial direction.
[0033] Based on the above-mentioned preferred drainage tube 5, the drainage tube 5 is made of a plastic material which can be cut off. Therefore, medical staff can change the hole diameter of the holes 5.1 on the drainage tube 5 according to the condition of different patients and the amount of exudate.
[0034] Preferably, the bag body 1 is made of a flexible plastic material. The front surface of the bag body 1 is transparent, or the front surface 1.1 of the bag body 1 has a transparent observation area 1.1.1 at a position corresponding to the exudate collection port 1.3. Therefore, the situation of the exudate sucked by the drainage tube in the bag body 1 can be observed in time, and the blockage of the holes 5.1 on the drainage tube 5 can be found by the patient or the patient's family or medical staff in time.
[0035] As shown in Figure 2 and Figure 4 The drainage tube 5 is provided with a bottom drainage hole 5.4 at a position corresponding to the bottom of the inner cavity of the bag body 1. Although most of the exudate can flow into the negative pressure balloon 4 through the drainage tube 5 during the process of negative pressure suction of the exudate by the drainage tube 5 on the wound of the patient, part of the exudate will remain in the bag body 1 and accumulate at the bottom of the bag body 1. During the cleaning process after the bag body 1 is detached from the patch 2, the sewage in the bag body 1 can be sent into the drainage tube 5 through the bottom drainage hole 5.4 by flushing clean water into the exudate collection port 1.3, and finally discharged from the end corresponding to the negative pressure balloon 4, which facilitates the cleaning of the bag body 1.
[0036] As shown in Figure 2 and Figure 4As shown, due to the possibility of clogging the small holes 5.1 on the drainage tube 5 during the process of absorbing the exudate of the patient's wound, if the bag 1 needs to be disassembled and processed every time the clogging occurs, not only the operation is inconvenient, but also the repeated opening of the bag 1 increases the risk of wound infection. Therefore, the improvement of the embodiment is that the part of the drainage tube 5 outside the bag 1 is provided with a switch valve 6 for opening and closing the drainage tube 5, and the end of the drainage tube 5 inside the bag 1 has an auxiliary ball 5.3 with an inner diameter larger than the diameter of the drainage tube 5. Thus, when it is found that the small holes 5.1 on the drainage tube 5 are clogged to a certain extent, the switch valve 6 can be closed, and the auxiliary ball 5.3 can be squeezed through the bag 1 to reverse the dirt adsorbed on the small holes 5.1 and flush it out. The dirt will be detached from the small holes 5.1 and remain in the bag 1, which can be cleaned at one time.
[0037] Preferably, the auxiliary ball 5.3 is located at the edge of the bag 1. That is, as shown in Figure 1 and Figure 2 As shown, the auxiliary ball 5.3 is located in the position close to the top side wall of the inner cavity of the bag 1, so that the top of the bag 1 does not turn outward and downward to form a curled edge after the whole bag 1 is under negative pressure suction. Due to the supporting effect of the auxiliary ball 5.3, the top of the bag 1 can remain flat. In addition, since the auxiliary ball 5.3 is closer to the top of the bag 1, the auxiliary ball 5.3 can be pinched from the front 1.1 and back 1.2 positions of the top of the bag 1 at the same time, and the auxiliary ball 5.3 can be squeezed. Compared with the auxiliary ball 5.3 located in the middle position of the bag 1, it is more convenient for patients or medical staff to squeeze the auxiliary ball 5.3 when needed.
[0038] Although the embodiments of the present application have been shown and described above, it should be understood that the above embodiments are exemplary and should not be construed as limiting the present application. Those skilled in the art can make changes, modifications, replacements and variations to the above embodiments within the scope of the present application.
[0039] For those skilled in the art, various changes and modifications will undoubtedly be apparent after reading the above description. Therefore, the appended claims should be considered as covering all changes and modifications within the true intent and scope of the present application. Any and all equivalent ranges and contents within the scope of the claims should be considered as still within the intent and scope of the present application.
