Technical Field

[0001] The present invention belongs to the technical field of metering bags, and more specifically, it is a disposable postpartum hemorrhage metering bag. Background Art

[0002] Postpartum hemorrhage is one of the serious complications during the delivery period. Rapid and accurate assessment of the blood loss is crucial for clinical treatment and reducing the risk to the parturient. Currently, the widely used blood collection basins in clinics mostly use open containers placed under the parturient's buttocks to collect blood. However, there are significant defects in actual applications: First, when the parturient changes position or the blood loss is large, the blood is likely to overflow from the edge of the basin, resulting in the actual collected amount being lower than the true blood loss. Second, traditional blood collection basins mostly use transparent materials with simple scale markings on the outer wall. However, due to the easy tilting of the basin, uneven blood distribution, and interference from light refraction, it is difficult for medical staff to quickly read accurate values. Third, when it is necessary to transfer blood samples for secondary testing in some scenarios, the open pouring operation is likely to cause contamination and there are metering errors.

[0003] The existing improved collection bags have metering functions, but the bags are prone to displacement, there are problems with body position adaptability, it is easy to cause incomplete collection, and there is a risk of liquid leakage.

[0025] The following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0026] Embodiment 1: As shown in the attached Figure 1 To Attachment Figure 5 As shown: The present invention provides a disposable postpartum bleeding volume measuring bag, comprising a collecting bag 1, a first rope group 5 and a second rope group 6;

[0027] A positioning ring 3 is installed at the mouth of the collecting bag 1. The positioning ring 3 can fix the shape of the mouth of the collecting bag 1 to keep it open, which is convenient for receiving blood. The positioning ring 3 enhances the stability of the bag mouth and reduces the problem of incomplete collection caused by changes in body position. A receiving bag 2 is connected to the upper side of the mouth of the collecting bag 1. The two side walls of the receiving bag 2 are provided with an unfolding portion 201. The unfolding portion 201 is funnel-shaped, and a folding portion 202 is provided at the connection between the unfolding portion 201 and the receiving bag 2. The outer surface of the collecting bag 1 is provided with a first scale line 9. When working, the collecting bag 1 is The bag 1 is placed at a suitable position on the buttocks of the parturient through the positioning ring 3, and fits the buttocks of the parturient through the annular hard structure to ensure that the opening position of the collection bag 1 is fixed to avoid displacement and blood leakage; the funnel-shaped expansion part 201 forms an expansion in a natural drooping state to expand the blood receiving area, and the folding part 202 allows the expansion part 201 to adjust the angle according to the body position of the parturient to prevent blood from splashing due to body activities; the first scale line 9 is directly printed on the outer wall of the collection bag 1, using a transparent or translucent material, and the amount of blood is directly displayed through the liquid level height;

[0028] The first rope group 5 includes a first short rope 501 and a second short rope 502; the two first rope groups 5 are symmetrically installed on the top wall of the unfolding portion 201;

[0029] The second rope group 6 includes a first long rope 601 and a second long rope 602; the first long rope 601 and the second long rope 602 are respectively connected to both side walls of the receiving bag 2; both the first rope group 5 and the second rope group 6 are equipped with Velcro 7; the first rope group 5 is symmetrically connected to the top of the unfolding part 201 through the first short rope 501 and the second short rope 502, pulling up the edge of the unfolding part 201 to form a stable flared opening; the first long rope 601 and the second long rope 602 extend from the side wall of the receiving bag 2 to the fixed points on both sides of the delivery bed, and the tightness is adjusted through the Velcro 7 to ensure that the bag body closely adheres to the part of the parturient's buttocks and the root of the thigh, preventing side leakage; the double-rope group design realizes multi-dimensional fixation. The first rope group 5 controls the unfolding shape of the bag opening, and the second rope group 6 adjusts the overall fitting degree, avoiding the problem that the traditional single-point fixation is easy to loosen; the Velcro 7 provides functions of quick adjustment and repeated fixation, adapting to different delivery bed structures and parturient body types, and improving the operation convenience.

[0030] As can be seen from the above, place the positioning ring 3 of the collection bag 1 under the parturient's buttocks, and use its annular rigid structure to fit the buttocks curve to keep the bag opening steadily open and avoid displacement; symmetrically lift the edge of the top wall of the unfolding part 201 through the first short rope 501 and the second short rope 502 of the first rope group 5, so that the funnel-shaped unfolding part 201 fully unfolds to form a flared opening, increasing the blood receiving surface; at the same time, the folding part 202 automatically adjusts the unfolding angle according to the parturient's body position to adapt to the activity needs.

[0031] Before blood collection, fix the first long rope 601 and the second long rope 602 of the second rope group 6 to the brackets or guardrails on both sides of the delivery bed through the Velcro 7, and adjust the tightness so that the receiving bag 2 closely adheres to the part of the parturient's buttocks and the root of the thigh, eliminating the risk of side leakage.

[0032] After the blood flows into the collection bag 1, the medical staff directly observes the liquid level height through the first scale line 9 on the outer wall of the transparent bag body to obtain the blood volume data in real time.

[0033] Fix the position of the bag opening of the collection bag 1 through the positioning ring 3, combine with the funnel-shaped unfolding part 201 to expand the blood receiving area, and the folding part 202 flexibly adapts to the change of the parturient's body position, effectively reducing the problems of blood spillage and incomplete collection; the first rope group 5 symmetrically lifts the edge of the unfolding part 201 to form a stable flared opening, and the second rope group 6 adjusts the tightness through the Velcro 7 to make the receiving bag 2 closely adhere to the part of the parturient's buttocks and the root of the thigh, realizing multi-dimensional fixation and avoiding the defect that the traditional single-point fixation is easy to loosen; the first scale line 9 on the outer wall of the collection bag 1 intuitively shows the liquid level height, simplifies the real-time monitoring process, and significantly reduces the reading error; the overall design takes into account the comfort of the parturient and the operation convenience, improves the accuracy of clinical blood volume assessment and the timeliness of treatment through the structural adaptability and adjustability, and at the same time reduces the pollution risk caused by the displacement of the device or the splashing of liquid.

[0034] Embodiment 2: As shown in the appendix Figure 2 To the appendix Figure 5As shown: This embodiment is basically the same as the previous embodiment, except that it further includes a measuring bottle 11. A discharge port 8 is connected to the bottom surface of the collection bag 1. A connection port 15 is provided at the top of the measuring bottle 11. The connection port 15 is threadedly connected to the discharge port 8. A limiting ring 16 is provided on the inner wall of the discharge port 8, and a sealing piece 17 is provided on the inner wall of the limiting ring 16; the sealing piece 17 is an aluminum foil composite film. A cutting edge 18 is fixed at the top of the connection port 15, and the position of the cutting edge 18 corresponds to that of the sealing piece 17; the cooperation between the sealing piece 17 and the cutting edge 18 realizes aseptic transfer that can be used immediately, avoiding secondary pollution; the threaded connection ensures tightness, preventing liquid leakage or air from mixing in.

[0035] When it is necessary to transfer a blood sample, screw the connection port 15 of the measuring bottle 11 into the discharge port 8 of the collection bag 1. As the screw thread rotates, the cutting edge 18 pierces the sealing piece 17, and the blood flows into the measuring bottle 11 through the discharge port 8; the aluminum foil composite film sealing piece 17 isolates air when not connected, preventing contamination or leakage.

[0036] Second scale lines 12 are provided on the outer wall of the measuring bottle 11, and the values of the first scale lines 9 correspond to those of the second scale lines 12; the first scale lines 9 of the collection bag 1 and the second scale lines 12 of the measuring bottle 11 adopt a linkage calibration method. For example, when the liquid level in the collection bag 1 reaches the corresponding value of the first scale line 9, after being discharged into the measuring bottle 11, by comparing the second scale lines 12, data consistency can be ensured; the double-scale linkage design eliminates the measurement error during the transfer process, improving data reliability; it is convenient for medical staff to obtain unified data at different stages (real-time monitoring and laboratory testing).

[0037] A bottom port 13 is connected to the bottom surface of the measuring bottle 11, and a sealing cap 14 is in threaded cooperation with the bottom port 13; after the sealing cap 14 is tightened, it closes the bottom port 13, forming an independent sealed container, which is convenient for storing or sending the blood sample for inspection; when it is necessary to pour, open the bottom port 13 to avoid the pollution risk caused by operating from the bottle mouth.

[0038] As can be seen from the above, when it is necessary to transfer a blood sample, screw the connection port 15 at the top of the measuring bottle 11 into the discharge port 8 at the bottom surface of the collection bag 1. During the threaded connection process, the cutting edge 18 pierces the aluminum foil composite film sealing piece 17 at the limiting ring 16 in the discharge port 8, so that the blood flows into the measuring bottle 11 through the discharge port 8. The first scale lines 9 on the outer wall of the collection bag 1 and the second scale lines 12 on the outer wall of the measuring bottle 11 adopt a linkage calibration design. For example, when the liquid level in the collection bag 1 reaches "500 mL", after being transferred to the measuring bottle 11, it corresponds to the same value of the second scale line 12, ensuring measurement consistency. After the sample transfer is completed, tighten the sealing cap 14 to close the bottom port 13 of the measuring bottle 11, forming an independent sealed container, which is convenient for storage or sending for inspection; when it is necessary to pour the sample, open the bottom port 13 for operation to avoid contaminating the bottle mouth.
