[0028] In the drawings, the same or similar notations are used to represent the same or similar elements or elements having the same or similar functions. The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0029] In the description of the present application, the terms "center", "longitudinal", "transverse", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the scope of protection of the present application.

[0030] The metered labor pad according to the embodiments of the present application can be used to collect amniotic fluid and postpartum hemorrhage.

[0031] As shown in Figure 2 The metered labor pad according to an embodiment of the present application includes a pad sheet body 1. The pad sheet body 1 is used, for example, to spread on the delivery bed when the parturient woman gives birth, and the pad is placed under the parturient woman's body. The pad sheet body 1 can also be regarded as the base body of the entire metered labor pad. The pad sheet body 1 is generally square or rectangular, and can also be provided in a shape similar to a rectangle, for example, with rounded corners at the corner portions of the front and rear ends.

[0032] The size of the main body of the diaper sheet 1 can be set as needed, for example, slightly wider or slightly narrower than the delivery bed, all of which are within the scope of protection of this invention. For example, the size of the main body of the diaper sheet 1 can be set to 90cm x 95cm.

[0033] The material of the sheet body 1 can be set as needed; for example, the sheet body 1 can be made of a water-repellent or hydrophobic material. In an optional embodiment, the material of the sheet body 1 is a water-repellent non-woven fabric. The color of the sheet body 1 can be set to blue or white.

[0034] The main body 1 of the form can be equipped with left and right indicator information and / or front and back indicator information to provide corresponding prompts. For example, the prompt information can be printed.

[0035] The main body of the sheet (1) can also be equipped with left and right hand pockets and hand markings to facilitate hand placement by medical staff, thereby improving cleaning performance. See also... Figure 3 and Figure 4 The left and right hand pockets 61 and 62 are formed by the flanges 6 of the main body of the sheet 1. The flanges 6 enhance the strength of the main body of the sheet 1 at its ends. Furthermore, by setting appropriate seams, the left and right hand pockets 61 and 62 can be formed on both sides. The operator can then place the main body of the sheet 1 securely and reliably under the patient's or postpartum woman's hips and lower back by inserting their hands into the left and right hand pockets respectively, ensuring a tight fit.

[0036] In other words, a flange 6 is provided at the front end of the sheet body 1. An adhesive strip 7 is provided on the back side away from the flange 6 for bonding and fixing the sheet body 1 to the delivery bed or operating table. A left hand pocket 61 and a right hand pocket 62 are formed on the left and right sides of the flange 6, respectively, so that the operator can insert their hands to unfold and lay out the sheet body 1.

[0037] A blood collection bag 2 is provided on the main body 1 of the sheet. The blood collection bag 2 is integrally connected to the main body 1 of the sheet and is used to collect amniotic fluid and blood. In one embodiment, the blood collection bag 2 is completely formed and then fixedly connected to the main body 1 of the sheet. Alternatively, the blood collection bags can be added to the main body 1 of the sheet layer by layer.

[0038] In the illustrated embodiment, the blood collection bag 2 includes an inner layer 21, a middle layer 22, and an outer layer 23. The inner layer 21 and the middle layer 22 are connected to each other to form an amniotic fluid collection bag 24 with an open front end, which is used to collect amniotic fluid. The amniotic fluid collection bag 24 can be configured in an inverted trapezoidal shape that is wider at the top and narrower at the bottom.

[0039] The middle layer 22 and the outer layer 23 are interconnected to form a blood collection bag 25 with an open front end. The blood collection bag 25 is used to collect postpartum bleeding and has a V-shaped shape that is wider at the top and narrower at the bottom. As mentioned earlier, an inverted trapezoidal shape also falls under the V-shaped shape defined in this patent. This shape can also be described as a funnel-shaped structure, referring to the shape of the blood collection bag, which resembles a funnel. Compared to a triangular structure, the length of the blood collection bag is reduced, thus helping to prevent its bottom from easily touching the ground. This further avoids interference with the smoothness of the blood collection process and prevents such contact from affecting the accuracy of the bag's scale readings. This facilitates more accurate acquisition of bleeding volume data.

[0040] In other words, both the amniotic fluid collection bag 24 and the blood collection bag 25 are formed by two interconnected layers, sharing a common intermediate layer 22. This results in a more compact structure and saves on material usage.

[0041] In this invention, "front" refers to the direction corresponding to the mother's head, and "back" refers to the direction corresponding to the mother's feet. This usually refers to the entire measuring labor pad being laid flat on the delivery bed. However, it should be understood that in actual clinical use, a portion of the measuring labor pad will extend downwards from the delivery bed. This facilitates the collection of amniotic fluid and blood using blood collection bags.

[0042] The blood collection bag 25 is V-shaped, wider at the top and narrower at the bottom, or wider at the front and narrower at the back. In clinical use, the blood collection bag hangs from top to bottom, thus collecting blood within it. The V-shape allows for more noticeable changes in blood level even with relatively small variations in blood volume. This improves the accuracy of blood volume measurement.

[0043] Similarly, the amniotic fluid collection bag 24 can also be configured in a V-shape that is wider at the top and narrower at the bottom, or in other words, a V-shape that is wider at the front and narrower at the back. In clinical use, the amniotic fluid collection bag 24 hangs from top to bottom, thereby collecting amniotic fluid in the amniotic fluid collection bag 24.

[0044] Furthermore, this inverted trapezoidal blood collection bag 25, while maintaining a relatively large collection capacity, eliminates the need for medical staff to frequently adjust the bag's position during blood collection, reducing cumbersome steps and significantly improving work efficiency. Regarding data accuracy, by eliminating interference factors such as shaking caused by the bottom touching the ground and blood residue, readings are more precise and reliable, providing doctors with more accurate data support for assessing postpartum hemorrhage and aiding in subsequent treatment decisions. Moreover, the optimized design reduces the overall space occupied by the blood collection bag, making it easier to place and store in space-constrained medical environments such as wards and operating rooms, thus improving the utilization efficiency of medical space.

[0045] Blood collection bag 2 can be designed as a single piece and made of PE material. This material has excellent water-repellent properties, a smooth surface, and low affinity for blood. When blood flows into the blood collection bag, thanks to its water-repellent properties, the blood will not adhere to the bag wall or inside, allowing it to flow freely.

[0046] Meanwhile, the elimination of the non-woven filter inside the blood collection bag reduces costs and allows blood to flow smoothly and continuously, significantly improving the efficiency of blood collection. Whether in emergency situations involving massive bleeding or in routine blood collection scenarios, this optimized design ensures efficient and rapid blood collection, saving valuable time for subsequent medical testing and treatment.

[0047] The front end of the inner layer 21 is fixedly connected to the main body 1 of the pad. Thus, the entire blood collection bag 2 is fixedly connected to the main body 1 of the pad. In one optional embodiment, the connection between the inner layer 21 and the main body 1 is a horizontally extending strip area. In another optional embodiment, in addition to the front end, certain other parts of the inner layer 21 are also connected to the main body 1 of the pad; or the entire inner layer 21 is connected to the main body 1 of the pad. These methods are all within the scope of protection of this invention.

[0048] A nursing drape 31 is fixedly connected to the front end of the intermediate layer 22. The nursing drape 31 is used to select whether to use an amniotic fluid collection bag 24 or a blood collection bag 25 for collection. When the nursing drape 31 is folded backward, the amniotic fluid collection bag 24 is opened and the blood collection bag 25 is closed. When the nursing drape 31 is folded forward, the amniotic fluid collection bag 24 is closed and the blood collection bag 25 is opened. For example, see... Figure 5 .

[0049] In other words, the nursing pad 31 can be opened upwards (i.e., folded up) and used as a buttock pad to reduce contamination. Furthermore, the nursing pad 31 is also used to open or close the amniotic fluid collection bag 24 and the blood collection bag 25. Its material can be the same as that of the pad body 1.

[0050] The size of the nursing pad 31 can be adjusted as needed. For example, it can be set to 65cm x 40cm.

[0051] The blood collection bag 25 is provided with a measuring scale 5 for measuring the volume of liquid collected by the blood collection bag 25. Specifically, the measuring scale 5 is located on the outer layer 23.

[0052] To facilitate clear display of the measurement scale lines 5, the outer layer 23 is transparent, and the measurement scale lines 5 set on the outer layer 23 are white. Correspondingly, the color of the pad body 1 is set to blue, for example.

[0053] The lower end of the blood collection bag 25 extends downward beyond the lower end of the amniotic fluid collection bag 24, and the measurement scale line 5 on the outer layer 23 corresponds to a scale of 500 ml at the lower end of the amniotic fluid collection bag 24. This structure allows a nursing sheet 32 ​​to be fixedly connected to the front end of the outer layer 23. The nursing sheet 32 ​​is used to lay on a mobile nursing table to place the placenta and collect blood.

[0054] A nursing sheet 32 ​​is fixedly connected to the front end of the outer layer 23. The nursing sheet 32 ​​is laid out on a mobile nursing table for placing the placenta and collecting blood. The mobile nursing table is located beside the delivery bed and is used for placing the placenta and collecting blood; if necessary, it can also hold corresponding instruments and supplies. The material of the nursing sheet 32 ​​can be the same as that of the sheet body 1. The size of the nursing sheet 32 ​​can be set as needed. For example, the size of the nursing sheet 32 ​​can be set to 60cm x 60cm.

[0055] The V-shaped drainage bag includes two water-repellent drainage strips 4, which are fixedly mounted on the main body of the sheet 1 and protrude from the main body of the sheet 1. The two water-repellent drainage strips 4 are located on the left and right sides of the main body of the sheet 1 and are used to guide amniotic fluid or blood to the amniotic fluid collection bag 24 or the blood collection bag 25.

[0056] The front end of the water-repellent strip 4 extends into the left pocket 61 or the right pocket 62, and the rear end of the water-repellent strip 6 extends into the inner layer 21 and is fixedly connected to the inner layer 21. As mentioned above, the two water-repellent strips 4 extend obliquely, and the left-right distance at the front end is greater than the left-right distance at the rear end.

[0057] The main body of the pad is made of water-repellent non-woven fabric, and the blood collection bag 2 is made of transparent PE.

[0058] The width of the nursing pad 31 is, for example, set to be less than the width of the front opening of the amniotic fluid collection bag 24 and the blood collection bag 25, and the width difference is less than 2cm.

[0059] In addition to being used in delivery beds, the product of this invention can also be used in hospital clinical departments and during surgery to collect disposable drainage fluids (blood, gastric juice, etc.), secretions (sputum, irrigation fluid, etc.) and human excretions from patients.

[0060] An example method of using the V-shaped drainage bag according to an embodiment of the present invention includes the following steps.

[0061] Step 1: Place a V-shaped amniotic fluid collection bag before delivery. (The amniotic fluid collection bag should be open for 24 seconds.)

[0062] The midwife or other personnel insert their left and right hands into the corresponding left hand pocket 61 and right hand pocket 62, respectively. Gently shake the V-shaped drainage bag to fully unfold it. Place the PCPH-V-shaped drainage bag on the operating table, below the mother's lower back. Figure 3 The oval-shaped area should be roughly aligned with the mother's buttocks. At the same time, ensure that at least most of the blood collection bag is hanging downwards. For example, ensure that at least 80% of the blood collection bag is hanging downwards, so that most of the bag's volume is usable.

[0063] In the fully unfolded state described in step 1, the amniotic fluid collection bag 24 must be in the open state. In this state, the nursing drape 31 is folded backward and downward, thereby opening the amniotic fluid collection bag 24. Thus, guided by the water-repellent drainage strip 4, the amniotic fluid discharged onto the drape body 1 during labor is guided and collected in the amniotic fluid collection bag 24, that is, collected in the containment space defined by the inner layer 21 and the middle layer 22.

[0064] Understandably, because the nursing pad 31 is folded back and down and placed on top of the nursing pad 32 and the outer layer 23, the opening between the outer layer 23 and the middle layer 22 is closed by the nursing pad 31, and the blood collection bag 25 is in a closed state.

[0065] Step 2: Switch the V-shaped drainage bag to the blood collection position. (Blood collection bag 25 is in the open position)

[0066] After the baby is delivered, clean and wipe the infant and settle him / her properly. After this, or at the same time, help the mother to gently lift her buttocks, fold the nursing pad 31 forward so that it is placed on the main body of the pad 1 and placed under the mother's buttocks.

[0067] Because the nursing pad 31 is folded forward, the opening between the outer layer 23 and the middle layer 22 is opened. That is, the nursing pad 31 no longer seals the blood collection bag 25, and the blood collection bag 25 is in an open state. In this state, guided by the water-repellent drainage strip 4, the blood discharged by the mother onto the nursing pad 31 or the main body of the pad 1 is guided and collected into the blood collection bag 25, that is, collected in the containment space defined by the middle layer 22 and the outer layer 23.

[0068] Understandably, in this state, the amniotic fluid collection bag 24 is closed by the nursing pad 31.

[0069] Step 3: Before the placenta is ready to be delivered, lay the nursing sheet 32 ​​flat on the mobile nursing table.

[0070] After the placenta is delivered, it can be examined and treated directly on nursing sheet 32.

[0071] It should be noted that this step is optional. The nursing sheet 32 ​​is optional. That is, in some embodiments, the V-shaped drainage bag of the present invention is provided with a nursing sheet 32, and thus this step is possible. In other embodiments, the V-shaped drainage bag of the present invention is not provided with a nursing sheet 32, and thus this step is not required.

[0072] In this step, the blood on the nursing drape 32 also flows along the drape 32 into the blood collection bag 25. Alternatively, the medical staff can slightly lift the nursing drape 32 at the end, allowing the blood on the drape 32 to flow into the blood collection bag 25. This improves the accuracy of blood collection.

[0073] Specifically, after the baby is delivered and just before the placenta is delivered, midwives and other medical staff lay the nursing drape extending from the outer bag flat on the nursing work table. After the placenta is delivered, medical staff can then proceed with placental disposal in an orderly manner using this drape. During the entire process, some blood will inevitably remain on the drape; this blood will flow into the blood collection bag (outer bag) connected to the nursing drape 32. Furthermore, the nursing drape protects medical staff during the procedure, greatly reducing the risk of cross-infection and effectively ensuring the health and safety of medical personnel.

[0074] Step 4: Read the amount of blood collected as indicated by the measuring scale on the blood collection bag 25.

[0075] The process may also include midwives performing final postpartum care, such as suturing the wound, checking for vaginal damage, and uterine massage.

[0076] After use, remove the product and place it in a designated medical waste container. This patented product can be a single-use product.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Those skilled in the art should understand that modifications can be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
