Description

Technical Field

[0001] The invention relates to the field of medical devices, and in particular to a urine drainage bag. Background Art

[0002] During the clinical use of existing urine bags, we have gradually discovered the following shortcomings and deficiencies in the process of long-term careful observation and research on the products:

[0003] First, after long-term experiments and research, we found that the current lateral drainage technology of urine bags is not designed reasonably. When the bag is full of liquid, it will expand, causing the front and rear walls of the liquid storage bag on the extension line of the bottom edge of the inner cavity just above the drainage pipeline to bend inward along the bottom edge of the inner cavity, thus hindering the emptying of the liquid in the upper bag. In addition, the drainage pipeline is set horizontally, resulting in slow drainage and liquid residue.

[0004] Second, the existing precision metering urine bags have many accessories, complex structures, complex production and manufacturing processes, and low efficiency, resulting in high costs. In particular, the design and manufacturing process of the metering box and siphon pipeline in the automatic precision metering urine bag has problems. As a result, there is no technology in the current existing technology that can truly achieve a reasonable design, simple structure, simple production and manufacturing process. Therefore, up to now, serial-type, especially automatic precision urine bags, cannot be popularized.

[0005] Third, in the current existing technology of serially connected precision metering urine bags, due to design problems, structure and manufacturing process and other reasons, the current products only have injection molded precision metering boxes, and there are no precision metering boxes manufactured by blow molding technology that can be used in series, especially in the manufacturing of complex structured self-controlled precision metering urine bags.

[0006] Fourth, in the current self-controlled precision metering urine bag technology, due to structural design problems, there is residual discharge and the metering is inaccurate.

[0007] Fifth, in the current self-controlled precision metering urine bag technology, the precision metering box and the liquid storage bag body are connected in series. Due to the connection and fixation between the two and the need for the self-controlled precision metering urine bag itself to be fixed, the current solution is to install a liquid storage bag body hanger with a hook on the lower back of the precision metering box to hang the liquid storage bag body. In this way, the accessories need to be separately injection molded and welded and assembled, which increases the manufacturing cost and process difficulty.

[0008] Sixth, in the currently available self-controlled precision metering urine bag technology, the liquid storage bag body is a soft film bag body, the metering error is large, and the volume marked with scale lines is inaccurate, which can easily lead to misreading.

[0009] Seventh, in the current serial precision metering urine bag technology, the overall length of the product is too long and the hanging problem hinders the popularization and promotion of the product.

[0010] Eighth, in the self-controlled precision metering urine bag technology, the self-draining capacity of the precision metering box is usually 500 ml. There is no further research and record on the precision metering self-draining capacity and the volume marking volume of the liquid storage bag body in various literature records and public knowledge. However, in our research, we found that when the self-draining rated capacity of the precision metering box is too small, the error is large and it is easy to be disturbed, while 500 ml is too large. Due to the height limit, the measurement is inaccurate, especially the measurement error within 100 ml is large. Summary of the invention

[0011] In view of the problems existing in the background technology, the purpose of the present invention is to provide a urine drainage bag with a reasonable design, which can solve the problem that when the liquid volume of the side urine drainage bag is full, the bag body expands, causing the front and rear walls of the liquid storage bag body on the extension line of the bottom edge of the inner cavity above the side drainage pipeline to be concave inward along the bottom edge of the inner cavity, and the liquid drainage is fast, there is no liquid residue, and it can be blow-molded to manufacture a self-draining precision metering box, which has a simple production and assembly process, a fixed user, and a reasonable design, simple process, and convenient use. To achieve the above purpose, the technical solution adopted by the present invention is as follows: the bottom edge of the inner cavity on one side of the bottom of the inner cavity of the liquid storage bag body is inclined downward to the lower edge of the inner opening of the drainage pipeline of the liquid storage bag body; the drainage pipeline of the liquid storage bag body below the bottom edge of the inner cavity on the other side of the liquid storage bag body is inclined downward to the upper edge of the inner opening of the drainage pipeline of the liquid storage bag body, and runs from the bottom of the inner cavity of the inner liquid storage bag body to the side of the liquid storage bag body.

[0012] In a preferred implementation state, the length of the bottom edge of the inner cavity of the liquid storage bag body that is inclined toward the lower edge of the inner opening of the liquid storage bag body discharge pipeline is not less than 1 / 3 of the bottom width of the inner cavity of the liquid storage bag body.

[0013] In a preferred implementation state, the two pipeline ends of the short drainage passage and the siphon drainage passage connected to the top of the liquid storage bag body are connected to the inner cavity of the precision metering box body after merging; a drainage switch is arranged on the short drainage passage.

[0014] In a preferred implementation state, the volume of the precision metering box body that triggers automatic discharge is 250 ml.

[0015] In a preferred implementation state, two pipe joints connected to the short drainage passage and the siphon drainage passage are arranged below the bottom of the inner cavity of the precision metering box body.

[0016] In a preferred implementation state, the precision metering box body and the two pipe joints arranged at the bottom are blow-molded in one piece.

[0017] In a preferred implementation state, the siphon drainage passage passes upward through the inwardly concave gap at the outer edge of the inner cavity bottom wall of the precision metering box body, and then turns downward through the inwardly concave gap at the outer edge of the inner cavity bottom wall of the precision metering box body to connect with the liquid storage bag body.

[0018] In a preferred embodiment, the rear wall of the precision metering box body is provided with an inwardly recessed groove for accommodating a siphon drainage passage.

[0019] In a preferred implementation state, suspension fixing seats communicating with the inner cavity of the precision metering box body are arranged on both sides of the precision metering box body.

[0020] In a preferred implementation state, the volume marking method of the liquid storage bag body is a scale area marking, and the area marking value is a multiple of the automatic liquid discharge volume of the precision metering box body.

[0021] All the above descriptions are based on the description of the precision urine bag in actual use. The directions and direction words are clear and are based on the mechanical design and drawing direction definitions.

[0022] Compared with the solutions in the prior art, the advantages of the present invention are:

[0023] First, the defects of the current lateral drainage technology of the liquid storage bag body, such as unsmooth drainage and unreasonable liquid residue design, are solved.

[0024] Secondly, since the manufacture of blow-molded precision metering boxes in serial-connected precision metering urine bags is realized, the difficulty and cost of the product manufacturing process can be reduced, and the manufacturing process and cost of serial-connected precision metering urine bags can be reduced, so that such products can be popularized and promoted.

[0025] Thirdly, the present invention is reasonably designed and solves the problem that the blow molding process cannot be used to manufacture the precision metering box in the serial precision metering urine bag, especially the design and process problems of the blow molding manufacturing of the precision metering box in the automatic precision metering urine bag.

[0026] Fourth, it solves the problem of residual discharge and inaccurate measurement due to structural design problems in the current self-controlled precision metering urine bag technology.

[0027] Fifth, solve the problem of hanging and fixing the serially connected precision urine bags, especially the problem of hanging and fixing the self-controlled precision metering urine bags.

[0028] Sixth, solve the problem that the current serial precision metering urine bag technology is too long in total length and cannot be popularized and promoted due to hanging.

[0029] Seventh, to solve the possible misreading of the liquid storage bag body in the currently existing automatic precision metering urine bag technology.

[0030] Eighth, the precision metering box is set with a self-draining capacity of 250 ml, which can take into account both precision and performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The advantages of this technical solution are: its design is reasonable, which solves the problem that when the bag is filled with liquid, the bag expands, causing the front and rear walls of the liquid storage bag on the extension line of the bottom edge of the inner cavity just above the discharge pipeline of the liquid storage bag to be concave inward along the bottom edge of the inner cavity, hindering the emptying of the liquid; the discharge pipeline tilts downward, the liquid is discharged quickly, and no liquid remains.

[0038] Embodiment 2:

[0039] like Figure 2As shown, the present invention comprises a precision metering box body (2), wherein the precision metering box body (2) and two pipe joints, an upper pipe joint (7) and a lower pipe joint (8) arranged at the lower part thereof, are integrally blow-molded; a liquid storage bag (6) is disposed below the precision metering box body (2); a short liquid discharge passage (10) is disposed below the bottom of the inner cavity of the precision metering box body (2) and connected to the liquid storage bag (6); the short liquid discharge passage (10) is equipped with a clip-type liquid discharge switch (9); wherein the short liquid discharge passage (10) is further divided obliquely upward into a siphon liquid discharge passage (1) connected to the liquid storage bag (6); the siphon liquid discharge passage (1) At the bottom of the inner cavity of the precision metering box body (2), it goes obliquely upward to the inner cavity of the inner cavity of the precision metering box body (2) on one side, through the gap, and runs along the groove in the inner cavity of the rear wall of the precision metering box body (2). After turning 180 degrees at the rated automatic liquid discharge positioning groove with a volume of 250 ml, it goes downward again through the inner cavity of the outer edge of the inner cavity of the precision metering box body (2) (the rear edge in this case) The gap is connected to the liquid storage bag body (6), and the end (5) of the siphon liquid discharge passage is located in the inner cavity of the liquid storage bag body (6); The groove on the rear wall of the metering box body (2) is in the shape of an "n"; the volume measurement marking method of the liquid storage bag body (6) is regional measurement, that is, the area between the two marking lines is the capacity area, and the capacity area value is a multiple of the volume of the precision metering box body (2) when the automatic discharge is started; the short discharge passage (10) and the siphon discharge passage (1) are plastic pipes, specifically PVC pipes; one side of the liquid storage bag body (6) below the precision metering box body (2) has an inner cavity bottom edge (11) that is inclined from top to bottom and from outside to inside toward the lower edge of the inner opening of the liquid storage bag body discharge pipe (14), and its length is greater than 1 / 1 of the width of the liquid storage bag body (6). / 3; the other side of the liquid storage bag body (6) is provided with an inner cavity bottom edge (12) which is inclined from top to bottom and from outside to inside towards the upper edge of the inner opening of the liquid storage bag body discharge pipeline (14); the discharge pipeline (14) arranged below it is inclined in the opposite direction towards the outer lower side of the liquid storage bag body (6) to one side of the liquid storage bag body (6), with the end facing downward; a discharge switch (13) is provided on the liquid storage bag body discharge pipeline (14); in this example, the discharge switch (13) is a sheet clip; hollow hanging fixing seats (3) are provided on both sides of the precision metering box body (2); the hanging fixing seats (3) are provided with a liquid storage bag hanging belt (41) and a precision urine bag fixing belt (42).

[0040] The advantages of this technical solution are that the two drainage pipes connected below the precision metering box body (2) in the serial precision urine bag can be realized by using the pipe joint at the bottom of the precision metering box body (2) or the pipe interface with an external PVC pipe. The precision metering box body (2) and the pipe joint below it (the vertical joint and the outer upper oblique joint in this example) can realize the integral blow molding of the precision metering box bottle body, and the external common PVC pipe is embedded in the "n" row groove on the back of the precision metering box body (2) to form a whole. In this way, the overall precise positioning and assembly of the siphon drainage passage (1) can be realized, and the problem of precise assembly of the soft (such as PVC hose) siphon drainage passage (1) during assembly and ensuring that it does not deform or shift during assembly, sterilization, transportation, and use can be solved. At the same time, the back of the precision metering box body (2) of the serial precision urine bag can be fixed to the edge of the bed, so that the function of the siphon drainage passage (1) is not affected and the fixation of the precision metering box body (2) is not hindered. The siphon drainage passage (1) as the starting point and the end point of the siphon pipeline are both below the bottom of the inner cavity of the precision metering box body (2), so that there is no residue in the drainage process of the precision metering box body (2) and precise quantitative drainage measurement can be achieved.

The hollow hanging fixing seats (3) are arranged on both sides of the precision metering box body (2) for the convenience of one-piece blow molding manufacturing; the hanging fixing seats (3) are provided with a liquid storage bag hanging belt (41) and a precision urine bag fixing belt (42) to simplify the process and facilitate manufacturing and use. One side of the liquid storage bag body (6) has an inner cavity bottom edge (11) inclined toward the lower edge of the inner opening of the liquid storage bag body discharge pipe (14), and the inner cavity bottom edge (11) is longer than 1 / 3 of the width of the liquid storage bag body (6) in order to reduce the residual discharge and prevent the front and rear walls of the liquid storage bag body on the extension line of the inner cavity bottom edge directly above the discharge pipe from being designed to be concave inward; the discharge pipe (14) is inclined downward in order to allow rapid and unobstructed discharge without residual liquid.

[0041] In actual operation, the self-discharge capacity of the precision metering box body (2) is set to 250 ml, which is the optimal capacity setting, taking into account both its precision and appropriate capacity, while taking into account the convenience of integer measurement of the liquid storage bag (6). When the content of the precision metering box body (2) reaches 250 ml of liquid, the siphon discharge is triggered to discharge the liquid into the inner cavity of the liquid storage bag (6). Each time the discharge volume is 250 ml, the corresponding metering area mark value of the liquid storage bag (6) is a multiple of it, which can meet the usage habits of the commonly used rated capacity of the bag body of 1000 ml, 1500 ml, 2000 ml, and 2500 ml.

[0042] The above is a detailed introduction to a urine drainage bag provided by the present invention. The principle and implementation mode of the present invention are explained in this article. The description of the above embodiments is only used to help understand the method of the present invention and its core idea. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation mode and application scope. In summary, the content of this specification should not be understood as a limitation on the present invention.
