Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and in particular relates to a postpartum hemorrhage monitoring device. Background Technology

[0002] Postpartum hemorrhage is one of the leading causes of maternal death and is extremely dangerous. By monitoring the amount of postpartum bleeding, medical staff can promptly detect abnormalities in postpartum hemorrhage. If excessive bleeding occurs within 2 hours postpartum, measures can be taken quickly to prevent further deterioration of the condition. Moreover, monitoring the amount of bleeding provides medical staff with accurate data support, helping them determine whether the current treatment plan is effective. If the amount of bleeding continues to increase or is not effectively controlled, medical staff can adjust the treatment strategy in a timely manner.

[0003] Current methods for monitoring postpartum hemorrhage include visual estimation and colorimetric methods. The latter involves using a sanitary napkin to absorb the blood, and estimating the amount of blood by measuring its red color. However, this requires doctors to have extensive experience to improve the accuracy of the estimation, and since it is all subjective estimation by doctors, the error is relatively large. Utility Model Content

[0004] The purpose of this invention is to provide a postpartum hemorrhage monitoring device that facilitates rapid and effective estimation of hemorrhage.

[0005] The postpartum hemorrhage monitoring device includes a sanitary napkin body, which includes a bottom layer, a top layer, and an absorbent core layer. The absorbent core layer has several first grooves on the side near the top layer, and the first grooves form several areas of the same area on the absorbent core layer. The first groove is filled with a first filler, which, upon contact with blood, displays a color different from red.

[0006] Furthermore, the first grooves are parallel to each other, and the first grooves are parallel to the width direction of the absorption core layer.

[0007] Furthermore, the absorbent core layer has several parallel second grooves on the side near the surface layer that are parallel to each other and parallel to the length direction of the absorbent core layer. The first filler is filled in the second groove, and the first and second grooves are connected and communicate with each other, forming several grids of the same area.

[0008] Furthermore, the first filler is anthocyanin in powder form.

[0009] Furthermore, a partition layer parallel to the surface layer is provided in the middle of the absorbent core layer, and the partition layer is used to prevent liquid penetration; The length of the separator is less than the length of the absorber core, and the separator is located in the middle of the length of the absorber core.

[0010] Furthermore, the material of the partition layer is the same as that of the bottom layer.

[0011] Furthermore, several third grooves parallel to the width direction of the absorbent core layer are formed on the absorbent core layer below the partition layer, and several fourth grooves parallel to the length direction of the absorbent core layer are formed on the absorbent core layer below the partition layer. The third and fourth slots are connected and form a grid. The third and fourth slots are filled with a second filler, the material of which is the same as that of the first filler.

[0012] Furthermore, a wire mesh is provided on the absorbent core layer.

[0013] Compared with the prior art, the present invention has the following beneficial effects: This invention fills a first filler into a first groove, and then, through the first groove, blood comes into contact with the first filler in areas of the same size on the absorbent core layer and displays different colors, thereby indicating the extent of blood contamination. By using these areas to quickly estimate the area of ​​blood, and by using the displayed areas as a reference, the amount of bleeding can be quickly estimated. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0016] This embodiment describes a postpartum hemorrhage monitoring device, such as... Figure 1 , Figure 2 and Figure 3As shown, the sanitary napkin body includes a bottom layer 1, a top layer 2, and an absorbent core layer 4. The bottom layer 1, top layer 2, and absorbent core layer 4 are all existing sanitary napkin structures. The top layer 2 is in contact with the human body, and the bottom layer 1 is used to prevent liquid leakage. It has protective wings on both sides to prevent side leakage. The absorbent core layer 4 has several first grooves on the side near the top layer 2. The first grooves form several areas of the same area on the absorbent core layer 4. The area of ​​blood is estimated by counting the blood-contaminated areas. The first grooves are filled with a first filler 3. The first filler 3 displays a color different from red after contacting blood.

[0017] The first filler 3 is powdered anthocyanin. Because the pH value of blood is about 7.35-7.45, which is weakly alkaline, when the blood comes into contact with the anthocyanin, the anthocyanin will turn blue-purple or blue, thus forming a blue-purple or blue frame. This is relatively obvious and easy to see intuitively. Moreover, the red color of the blood itself can be used to visually see whether the frame formed by the first and second grooves is completely covered by the blood or the approximate area covered. If it is not completely covered, two or three areas can be combined into one area for estimation based on the size of the coverage. Of course, in some embodiments, the first filler 3 can also be sodium fluorescein, which will turn yellow-green when it comes into contact with blood.

[0018] The first grooves are parallel to each other and parallel to the width direction of the absorbent core layer 4. The first grooves form several rectangular frames on the top of the absorbent core layer 4.

[0019] The absorbent core layer 4 has several parallel second grooves on the side near the surface layer 2, which are parallel to each other and parallel to the length direction of the absorbent core layer 4. The second grooves are filled with the first filler 3. The first grooves and the second grooves are connected and communicate with each other. The first grooves and the second grooves form several grids with the same area. The area can be estimated by the number of grids, which is convenient. Of course, in some embodiments, the first grooves and the second grooves can also be set at an angle so that the first grooves and the second grooves form several prismatic frames with the same area.

[0020] The absorbent core layer 4 has a partition layer 6 parallel to the surface layer 2 in the middle. The partition layer 6 is located in the middle of the thickness of the absorbent core layer 4 and is used to prevent liquid penetration. The material of the partition layer 6 is the same as that of the bottom layer 1, which is the bottom layer structure of existing sanitary napkins and is designed with an inverted funnel process. Of course, the partition layer 6 can also be a thin film to prevent liquid penetration.

[0021] The length of the partition 6 is less than the length of the absorbent core layer 4, and the partition 6 is located in the middle of the length of the absorbent core layer 4. When the absorbent core layer 4 above the partition 6 absorbs liquid, the liquid will first diffuse to both sides due to the obstruction of the partition 6 during use. After the diffusion range exceeds the partition 6, it will diffuse downwards and then diffuse to the absorbent core layer 4 at the bottom of the partition 6. This avoids the liquid from accumulating in the middle of the absorbent core layer 4 at the beginning, causing the middle of the absorbent core layer 4 to sag.

[0022] The absorbent core layer 4 below the partition 6 has several third grooves parallel to the width direction of the absorbent core layer 4, and the absorbent core layer 4 below the partition 6 has several fourth grooves parallel to the length direction of the absorbent core layer 4. The third grooves and fourth grooves are connected and communicate with each other, forming a grid. The grid formed by the third grooves and fourth grooves is smaller than the area of ​​the partition 6. The third grooves and fourth grooves are filled with a second filler 7. The material of the second filler 7 is the same as that of the first filler 3. Through the grid formed by the third grooves and fourth grooves, the amount of blood that has permeated to the area below the partition 6 can be estimated. In the calculation, the grid formed by the first filler 3 and the grid formed by the second filler 7 are the sum of the bleeding volume.

[0023] A mesh 5 is provided on the absorbent core layer 4. The mesh 5 is made of woven threads into a grid shape. The mesh 5 wraps the absorbent core layer 4, reducing the possibility of the absorbent core layer 4 breaking due to pulling or friction, reducing the accumulation or displacement of the absorbent core layer 4 during use, thereby reducing the local thinning of the absorbent core layer 4 and keeping the absorbent core layer 4 flat.

[0024] The working principle and technical effects of this embodiment; The usage method is consistent with the existing sanitary napkin usage method. When blood flows out, it is absorbed by the absorbent core layer 4 through the surface layer 2. When the blood comes into contact with the first filler 3, different patterns appear, thus forming a relatively obvious area. The area can be quickly estimated by the number of grids. The grid has a strong contrast and reference, making estimation relatively easy. With the setting of the partition layer 6, the blood and other liquids are first absorbed by the upper absorbent core layer 4 and then diffuse to both sides of the partition layer 6. Then, they flow downwards from both sides and gather at the bottom of the partition layer 6. This avoids the blood and other liquids from accumulating in the middle in the initial stage, causing an increase in weight in the middle, thereby reducing the sagging in the middle in the initial stage.
