SUMMARY

[0004] In view of the above problems, the present application provides a nursing pad for measuring the amount of vaginal bleeding, which aims to solve the problems existing in the prior art.

[0005] The specific technical solutions are as follows:

[0022] In the diagram: 1. Skin-friendly layer; 2. Measuring ring; 3. Conductive sheet. Detailed Implementation

[0023] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] The present invention will be further described below with reference to specific embodiments, but this is not intended to limit the present invention.

[0026] Figure 1 This is a front view structural diagram of the nursing pad for measuring vaginal bleeding according to this utility model, as shown. Figure 1 As shown, the nursing pad for measuring vaginal bleeding provided in this embodiment includes a skin-friendly layer 1, an absorbent layer, and an anti-permeability layer. The skin-friendly layer 1, absorbent layer, and anti-permeability layer are arranged sequentially from top to bottom. The upper surface of the skin-friendly layer 1 is provided with multiple concentric measuring rings 2 of different diameters. It also includes multiple sets of sensors and recording devices. The sensors are all electrically connected to the recording devices. The sensors are all set in the absorbent layer. The sensors in the same group are evenly arranged in the same measuring ring 2. When the permeation range of the absorbent layer absorbs liquid covers the sensors in the same group, the corresponding sensor outputs an electrical signal to the recording device.

[0027] It should be noted that the absorbent layer is in an insulating state when it does not absorb blood, but when it absorbs blood, the blood acts as a conductor and can conduct a weak current.

[0028] In the above embodiment, the distance between each measuring circle 2 is the same.

[0029] It should be noted that when the distance between the metering circles 2 is the same, the rate of bleeding increases from covering one metering circle 2 to covering the next metering circle 2. When it is necessary to ensure that the same bleeding amount is recorded, the area between each metering circle 2 needs to be set to be equal.

[0030] In the above embodiment, the relationship between the number of sensor groups B and the number of metering rings 2 A is B = nA, where the coefficient n is an integer greater than zero.

[0031] In the above embodiment, a set of sensors includes two conductive sheets 3. When the two conductive sheets 3 of the same set are placed on the metering ring 2, the distance between them is the greatest.

[0032] In the above embodiment, there is an angular deviation between the line connecting the same group of conductive sheets 3 on one metering ring 2 and the line connecting the same group of conductive sheets 3 on another metering ring 2.

[0033] In the above embodiment, the two conductive sheets 3 in the same group are respectively connected to different pins of the recording device. When the two conductive sheets 3 in the same group are connected due to blood permeation, the recording device and the two conductive sheets 3 in the same group form a circuit, that is, the corresponding bleeding amount is recorded.

[0034] It should be noted that the recording device is existing technology, requiring only a power supply, an electrical signal receiver, and an electrical signal conversion device. The conductive sheet 3, the power supply, the electrical signal receiver, and the conductive sheet 3 are connected in sequence. The electrical signal conversion device is connected to the output terminal of the electrical signal receiver, and the electrical signal conversion device is connected to an external receiver.

[0035] In the above embodiments, multiple adhesive fasteners are provided on the back of the anti-permeability layer, and fastening straps are provided at the edges and four corners of the anti-permeability layer.

[0036] Working principle: When in use, the nursing pad is laid under the patient and fixed to the bed using adhesive fasteners. Multiple fastening straps are used to further strengthen the fixation. The patient's vaginal opening is positioned as close as possible to the center of the measuring ring 2. After vaginal bleeding, the blood seeps into the skin-friendly layer 1 and is absorbed and locked by the absorbent layer. As the amount of bleeding increases, the seepage range expands. When the edge of the seepage range simultaneously contacts two conductive sheets 3 of the same set, the two conductive sheets 3 become interconnected, and the recording device records the amount of bleeding. When the seepage range continues to expand and covers another measuring ring 2, the two conductive sheets 3 of the other set become interconnected, and the recording device records the corresponding amount of bleeding again, until the measuring ring 2 is completely covered.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the content of the present utility model specification should be included within the protection scope of the present utility model.
