Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to a layered liquid collection bag. Background Art

[0002] Most patients undergoing urological surgery will have a urinary catheter indwelling after the operation to collect postoperative urine and observe the color, quality, and quantity of the urine to judge the postoperative bleeding symptoms of the patients.

[0003] Two types of urine bags are commonly used in clinical practice: one is a 2000 ml anti-reflux drainage bag connected to patients undergoing catheterization; the other is a 5000 ml anti-reflux drainage bag connected to patients undergoing bladder irrigation. The capacities of the two types of urine bags are relatively large, reducing the frequency of pouring urine. However, at the same time, there is a technical drawback: since the collected urine is stored in the same cavity of the bag body, the urine collected at different time periods is mixed together, and it is impossible to observe the properties of the urine collected in the urine bag during a certain time period, which may lead to missing the opportunity to correctly judge the bleeding of the patient's urinary system. The urinary system includes the kidneys, ureters, bladder, etc., affecting the accurate judgment of the properties of urine by medical staff during a certain time period. If medical staff pour the urine bag every once in a while to collect urine at different time periods, it will undoubtedly increase the workload of medical staff.

[0004] To sum up, the technical problem existing in the prior art is that it is impossible to separately collect urine at different time periods without replacing the urine bag to avoid the mixing of urine at different time periods and affecting the judgment of the properties of the patient's urine by medical staff. In other words, the core technical problem existing in the prior art is how to use the same urine bag to achieve the separate collection of urine at different time periods. Content of the Utility Model

The second fluid channel communicates with the first fluid channel through the fluid opening provided therein; the lower cavity adjacent to the upper cavity communicates with the upper cavity through the fluid opening provided therein.

[0017] Further, it further includes a liquid outlet pipe. Along the first direction, the liquid outlet pipe is connected to the lower cavity farthest from the upper cavity; and a switching valve is further provided on the liquid outlet pipe, and the switching valve is restricted outside the bag body.

[0018] Further, it further includes a handle, and the handle is connected to the bag body.

[0029] Embodiment 1

[0030] As Figures 1 to 2 shown, this embodiment provides a layered liquid - collecting bag, which includes a bag body 1. A number of barrier parts 2 are arranged in the bag body 1, and the bag cavity in the bag body 1 is divided into a plurality of functional cavities and a plurality of fluid channels by the barrier parts 2. Among them, the plurality of functional cavities are at least respectively configured as an upper cavity 3 and a number of lower cavities, and the upper cavity 3 and the number of lower cavities are arranged in sequence along the first direction. Any one of the fluid channels penetrates one of the lower cavities along the first direction, and fluid holes 6 are provided on the channel wall body of the fluid channel. Any one of the fluid channels is only communicated with the lower cavity penetrated by the fluid channel through the fluid holes 6 provided therein.

[0031] At the same time, one end of any one of the fluid channels facing the upper cavity 3 has a fluid opening. For any two adjacent fluid channels along the first direction, the fluid channel close to the upper cavity 3 is the first fluid channel 4, and the fluid channel away from the upper cavity 3 is the second fluid channel 5. The second fluid channel 5 is communicated with the first fluid channel 4 through the fluid opening provided therein. The lower cavity adjacent to the upper cavity 3 is communicated with the upper cavity 3 through the fluid opening provided therein.

[0032] A floating member 8 is also arranged in any one of the fluid channels. The density of the floating member 8 is a preset density. The floating member 8 is movable and inseparable in the fluid channel, and the floating member 8 can block the fluid opening or be separated from the fluid opening. It also includes a liquid inlet pipe 9, and the liquid inlet pipe 9 is connected to the upper cavity 3.

[0033] The bag body 1 is preferably made of a soft material, such as soft plastic, and has the advantage of being foldable; it has a bag cavity inside, and the formation of the bag cavity is not limited here.

[0034] The barrier part 2 is preferably formed by a hot processing technique, that is, the two side surfaces of the bag body 1 are heated. After the materials on both sides of the bag body are melted, they are bonded to each other and then cooled to form an adhesion. The adhered part is the barrier part 2. The number of the barrier parts 2 is multiple, so that the bag cavity in the bag body 1 is divided into multiple functional cavities and multiple fluid channels by the barrier parts 2.

[0035] Such as Figure 1 , Figure 4 As shown, at least multiple functional cavities are respectively configured as an upper cavity 3 and several lower cavities. In this embodiment, the number of lower cavities is two, namely the first lower cavity 16 and the second lower cavity 17. Along the first direction, the first lower cavity 16 is located between the second lower cavity 17 and the upper cavity 3.

[0036] In this embodiment, the first direction is the vertically downward direction; that is, along the vertical direction, the upper cavity 3 is located at the topmost layer, the second lower cavity 17 is located at the bottommost layer, and any fluid channel extends along the first direction.

[0037] Preferably, in order to enable the urine entering the upper cavity 3 to automatically converge and flow towards the first fluid channel or the second fluid channel under the action of gravity, in this embodiment, along the first direction, the barrier parts 2 are distributed in a converging shape, and the fluid opening is located at the end where the converging shape converges.

[0038] Correspondingly, in this embodiment, the fluid channel penetrating the first lower cavity 16 is the first fluid channel 4, and the fluid channel penetrating the second lower cavity 17 is the second fluid channel 5; moreover, a first fluid hole is provided on the inner wall of the channel of the first fluid channel 4, and the first fluid channel 4 communicates with the first lower cavity 16 only through the first fluid hole. A second fluid hole is provided on the inner wall of the channel of the second fluid channel 5, and the second fluid channel 5 communicates with the second lower cavity 17 only through the second fluid hole. A first fluid opening is provided at the end of the first fluid channel 4 facing the upper cavity 3, and the first fluid channel 4 communicates with the upper cavity 3 through the first fluid opening. A second fluid opening is provided at the end of the second fluid channel 5 facing the upper cavity 3, and the second fluid channel 5 communicates with the first fluid channel 4 through the second fluid opening.

[0039] The density of the floating member 8 is a preset density, and the preset density should be less than the density of human urine. In this way, after urine flows into the first fluid passage 4 and the second fluid passage 5 in this embodiment, the floating member 8 is located on the upper layer of the urine to achieve the purpose of blocking the fluid opening. In this embodiment, the number of floating members 8 is two, namely the first floating member and the second floating member. The first floating member is located in the first fluid passage 4 and is used to block or open the first fluid opening. The second floating member is located in the second fluid passage 5 and is used to block or open the second fluid opening.

[0040] Preferably, in order to prevent the floating member 8 from blocking the fluid hole, in this embodiment, along the radial direction of the fluid passage, the cross-sectional diameter of the floating member 8 is between the caliber of the fluid opening and the diameter of the circumscribed circle of the cross-section of the fluid passage.

[0041] As Figure 1 , Figures 4 to 6 As shown, when the layered liquid collection bag of this embodiment is in use, first, urine flows into the bag body 1 through the liquid inlet pipe 9. Under the action of gravity, the urine flows through the first fluid opening into the first fluid passage 4. The urine located in the first fluid passage 4 floats up the first floating member, and the first floating member opens the second fluid opening. The urine enters the second fluid passage 5 through the second fluid opening and then enters the second lower cavity through the second fluid hole provided on the inner wall of the second fluid passage 5. During this process, the liquid level of the urine in the second fluid passage 5 is always flush with the liquid level of the urine in the second lower cavity. As the urine is continuously collected, the liquid levels of the urine in the second fluid passage 5 and the second lower cavity rise continuously, and the second floating member is always located on the upper layer of the urine liquid level. This causes the second floating member to float up continuously and finally block the second fluid opening. At this time, the collection of urine in the second lower cavity is completed. Subsequently, the urine is continuously collected by the first lower cavity, and the collection process is similar to the above process until the first floating member blocks the first fluid opening. At this time, the collection of urine in the first lower cavity is completed. Subsequently, the urine is continuously collected by the upper cavity until the upper cavity is filled with urine, thus completing the layered collection of urine. The urine located in the second lower cavity is the urine flowing out in the first time period, the urine located in the first lower cavity is the urine flowing out in the second time period, and the urine located in the upper cavity is the urine flowing out in the third time period. Among them, the first time period, the second time period, and the third time period are arranged in the order of time passage. For example, the first time period is the 0s - 10s when the patient's urine flows out, the second time period is the 11s - 20s when the patient's urine flows out, and the third time period is the 21s - 30s when the patient's urine flows out, which is convenient for medical staff to observe the bleeding condition of the urine derived from the patient's body in different time periods.

[0042] As can be seen from the background technology, the technical problem existing in the prior art is: how to use the same urine bag to collect urine in different time periods separately.

[0043] In this embodiment, within the same bag body, an upper cavity 3 and several lower cavities are arranged along a first direction. The upper cavity 3 and the several lower cavities are respectively used for collecting urine. Moreover, the fluid opening for connecting the upper cavity 3 and the adjacent lower cavity can be blocked or opened by a floating member, and the fluid opening for connecting any two adjacent lower cavities can be blocked or opened by another floating member. Thus, along the first direction, urine is successively collected in the lowermost lower cavity, another lower cavity adjacent to the lower cavity of this layer,... and the upper cavity, thereby completing the layered collection of urine at different time periods. In summary, this embodiment solves the technical problem in the prior art of how to use the same urine bag to separately collect urine at different time periods.

[0044] Furthermore, as mentioned in the foregoing content, the floating member floats along the first direction within the fluid channel. Then, how to avoid the floating member from generating deflection along the radial direction of the fluid channel is a technical problem to be solved, and this technical problem is solved by the following technical solution.

[0045] The floating member 8 includes a plug 10 and a guide block 11 that are connected to each other along the first direction. The plug 10 can block the fluid opening; the outer surface of the guide block 11 has a clearance fit with the inner wall of the fluid channel where it is located.

[0046] In this embodiment, the floating member 8 is divided into two parts, the plug 10 and the guide block 11. Specifically, in this embodiment, the outer surface of the guide block 11 has a clearance fit with the inner wall of the fluid channel where it is located. During the floating process of the plug along the first direction, the clearance fit relationship between the outer surface of the guide block 11 and the inner wall of the fluid channel guides the floating path of the plug along the first direction. Therefore, this embodiment solves the technical problem of how to avoid the floating member from generating deflection along the radial direction of the fluid channel during the floating process.

[0047] Furthermore, as mentioned in the foregoing content, after the urine flows into the bag body 1 through the liquid inlet pipe 9, the urine passes through the first fluid channel 4 under the action of gravity. The urine located in the first fluid channel 4 floats the first floating member, and the first floating member opens the second fluid opening, and the urine enters the second fluid channel 5 through the second fluid opening. That is, the urine needs to accumulate a certain volume in the first fluid channel 4 before it can float the first floating member and then open the second fluid opening. That is, in the above solution, the urine entering the first fluid channel 4 cannot quickly enter the second fluid channel, resulting in too long a cumulative time required before the urine is collected in the second lower cavity. This technical problem is solved by the following technical solution.

[0048] Such as Figure 3As shown, a fluid through-hole 12 is provided on the guiding block 11, and the fluid through-hole 12 penetrates the guiding block 11 along the first direction.

[0049] In this embodiment, the number of the fluid through-holes 12 is multiple; when urine flows into the bag body 1 from the liquid inlet pipe 9 and then passes through the first fluid channel 4 under the action of gravity, instead of accumulating to a volume sufficient to float the first floating member, the urine directly enters the second fluid channel 5 through the fluid through-holes 12. That is, after the urine flows into the first fluid channel 4, it directly enters the second fluid channel 5 without accumulation, which speeds up the time for the second lower cavity to collect urine; in other words, before the urine is collected in the second lower cavity, the required waiting time does not include the time for the urine to accumulate to a volume sufficient to float the first floating member; that is, this embodiment solves the technical problem of the too long accumulation time required before the urine is collected in the second lower cavity. In other words, in this embodiment, the time before the urine is collected in the second lower cavity is shortened.

[0050] Furthermore, this embodiment also includes the following technical solution. The layered liquid collection bag further includes a liquid outlet pipe 13. Along the first direction, the liquid outlet pipe 13 is connected to the lower cavity farthest from the upper cavity 3; and, a switch valve 14 is further provided on the liquid outlet pipe 13, and the switch valve 14 is restricted outside the bag body 1.

[0051] The structure of the switch valve 14 is a prior art and will not be elaborated here. The function of the switch valve 14 is to open or close the liquid outlet pipe 13. After the layered liquid collection bag in this embodiment collects urine, the switch valve 14 can be opened to allow the urine to flow out from the liquid outlet pipe 13.

[0052] Furthermore, in order to facilitate the hanging of the layered liquid collection bag in this embodiment, the layered liquid collection bag in this embodiment further includes a handle 15, and the handle 15 is connected to the bag body 1; the handle 15 is used to hang the bag body on a medical bracket.

[0053] Furthermore, the layered liquid collection bag in this embodiment can be used to layer-collect other human tissue fluids in addition to collecting the urine of patients.

[0054] The above embodiments only express several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
