Description

Technical Field

[0001] The utility model relates to the technical fields of medical devices and the like, and in particular to a special blood collecting pad for measuring postpartum hemorrhage. Background Art

[0002] Postpartum hemorrhage is currently clinically defined as vaginal bleeding greater than 500 mL within 24 hours after delivery, and cesarean section bleeding greater than 1000 mL. It is a common and relatively serious complication of delivery. At the same time, 80% of postpartum hemorrhage occurs within 2 hours after delivery, which is one of the main causes of postpartum death. Therefore, it is extremely important to measure the amount of bleeding within 2 hours and 24 hours after delivery.

[0003] At present, the clinical measurement of postpartum hemorrhage is not accurate due to the influence of many factors, especially the mixing of amniotic fluid and blood during delivery, which is difficult to distinguish in time, which may lead to the delay of the best time for treatment. Therefore, accurate measurement of postpartum hemorrhage is of great significance for clinical medical staff to accurately judge and actively deal with it. The commonly used methods for measuring postpartum hemorrhage in vaginal delivery are blood collection basins and urine pads. However, the blood collection basin often has large measurement errors due to its lack of close fit and comfort with the buttocks of the parturient, inappropriate placement, easy overflow if the bleeding is fast and large, and the blood that penetrates the dressing cannot be collected; urine pads are difficult to separate amniotic fluid and blood during use, and there are differences in how to judge the amount of amniotic fluid, resulting in actual bleeding measurement errors. Both cannot accurately measure the amount of postpartum hemorrhage. Utility Model Content

[0024] like Figure 1 to Figure 2 As shown, a preferred embodiment of a blood collecting pad specially used for measuring postpartum hemorrhage is shown, which is characterized by comprising: a blood collecting pad 1 and a liquid collecting bag 2.

[0025] The blood collecting pad 1 is made by liquefying pure water and nanomolecular polymer through emulsification technology; the blood collecting pad 1 is provided with an opening 3; the liquid collecting bag 2 is detachably installed on the opening 3, and a filter membrane 4 is provided in the middle of the liquid collecting bag 2; the outer wall of the liquid collecting bag 2 is provided with volume scale lines 8, and a liquid discharge valve 5 is installed at the bottom end of the liquid collecting bag 2.

[0026] In actual use, the material of the blood collecting pad 1 is similar to that of a liquid sanitary napkin, and the size can be set to 120*100cm. The principle of the blood collecting pad 1 is: FlexFoamTM, which is liquefied by emulsification technology using pure water and nanomolecular polymers. It has a porous form similar to memory foam, has super absorbency, and can absorb 10 times its own weight. The flow rate has better absorption performance, is not easy to overflow, and has a soft touch. A liquid collecting bag 2 is set at the bottom of the blood collecting pad 1. The liquid collecting bag 2 has a scale, and the range can be set to 0-3000mL. When amniotic fluid and blood enter the liquid collecting bag 2, the filter membrane 4 can filter the amniotic fluid and blood. The amniotic fluid passes through the filter membrane 4 and enters the lower part of the liquid collecting bag 2, and is discharged through the drain valve 5 at the bottom of the liquid collecting bag 2. The blood is retained on the filter membrane 4, and the blood clot volume can be directly read through the volume scale line 8 on the liquid collection bag 2, and converted into blood volume [blood volume (mL) = blood clot weight (g) / blood specific gravity] according to the blood specific gravity of 1.050-1.060. The amount of bleeding can be quickly determined, which is convenient for midwives to accurately and intuitively assess the bleeding situation.

[0027] The utility model also has the following implementation methods based on the above:

[0028] Furthermore, a special blood collecting pad for measuring postpartum hemorrhage is characterized in that the longitudinal cross-section of the liquid collecting bag 2 is trapezoidal. Specifically, the trapezoidal liquid collecting bag 2 can make the amniotic fluid be better discharged from the liquid collecting bag 2.

[0029] Further, a blood collecting pad for measuring postpartum hemorrhage is characterized in that the blood collecting pad 1 can be connected to the liquid collecting bag 2 through a collecting tube 6. Specifically, the mixed liquid of amniotic fluid and blood can pass through the opening on the blood collecting pad 1, pass through the collecting tube 6, and finally enter the liquid collecting bag 2.

[0030] Furthermore, a blood collecting pad specially used for measuring postpartum hemorrhage is characterized in that the filter membrane 4 is treated by soaking in salt water, and sodium chloride particles are attached to the surface of the filter membrane 4. Specifically, the filter membrane 4 is treated by soaking in salt water, and sodium chloride particles are evenly attached to the filter membrane 4. When the mixture of amniotic fluid and blood contacts the filter membrane 4, sodium chloride mixes with the blood, and electrolysis produces anions and cations, which react with the blood colloid to cause coagulation, and the blood coagulates into blocks, which are trapped on the filter membrane 4, and the amniotic fluid flows into the lower end of the liquid collection bag 2 through the filter membrane 4, and the drain valve 5 further releases the amniotic fluid and other liquids, so that the blood in the mixture of amniotic fluid and blood flows into the liquid collection bag 2, and then reacts with sodium chloride to coagulate into blood clots, which are continuously and evenly accumulated on the filter membrane 4, and the amniotic fluid and other liquids flow into the lower liquid collection bag through the filter membrane 4 and are discharged through the drain valve 5.

[0031] Furthermore, a blood collecting pad specially used for measuring postpartum hemorrhage is characterized in that the blood collecting pad 1 is provided with a plurality of partitions 7 outwardly from the position of the opening 3, and a scale range is provided on each partition 7. Specifically, if the bleeding speed is fast, the blood collecting pad 1 can absorb the bleeding in time to prevent blood from overflowing, and the amount of amniotic fluid and blood absorbed by the blood collecting pad 1 can be roughly known through different partitions, so as to further better observe the amount of bleeding of the parturient, and the blood collecting pad 1 has an auxiliary effect and only absorbs the amount overflowed when the bleeding is excessive.

[0032] Furthermore, a blood collecting pad for measuring postpartum hemorrhage is characterized in that an adhesive layer is provided on the bottom surface of the blood collecting pad 1. Specifically, the blood collecting pad 1 can be attached to clothes or a bed, etc., so that the blood collecting pad 1 is not easy to move.

[0033] Furthermore, a blood collecting pad specially used for measuring postpartum hemorrhage is characterized in that a weight sensor is provided on the filter membrane 4. Specifically, the weight sensor can detect the weight of the blood clot, and when the amount of bleeding is too much, that is, when the blood clot is too heavy, the weight sensor can transmit a signal to an external receiver to serve as a warning to medical staff.

[0034] Furthermore, a blood collecting pad for measuring postpartum hemorrhage is characterized in that the inner walls of the opening 3 can be bonded together by an adhesive layer. Specifically, the liquid collecting bag 2 can be removed from the blood collecting pad 1, and the openings can be bonded together, so that the blood collecting pad 1 can be used as a common protective pad.

[0035] The above description is only a preferred embodiment of the present invention, and does not limit the implementation mode and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
