Semen collection sheet

Abstract

A semen collection sheet (1, 1A, 1B, 1C) has a front surface (target area RA) to which semen is attached and a rear surface having a fixing means (fixing portion 12). When the semen collection sheet is unfolded, a reservoir portion (RB) for collecting semen attached to the front surface is formed. A user unfolds the semen collection sheet at a clinic, home, or the like and fixes the semen collection sheet to a mounting surface W (a wall surface or the like) so that the reservoir portion is positioned vertically in a lower position. The user ejaculates aiming at the target area. The attached semen travels downward along the front surface by gravity and is collected in the reservoir portion.

Description

Technical Field

[0001] This invention relates to a device for collecting semen. Background Technology

[0002] In assisted reproductive technologies (ART) such as artificial insemination and in vitro fertilization, patients manually stimulate themselves to provide semen for collection in a container (Patent Document 1).

[0003] To provide semen for collection, the patient needs to hold the container with one hand and stimulate their genitals with the other. Typically, the collection container is small, and due to the patient's movement during stimulation, it is difficult to accurately provide the ejaculated semen into the container after ejaculation. If semen that has ejaculated outside the container is collected and stored inside, there is a risk of bacterial and other contamination.

[0007] The problem to be solved by the present invention

[0008] The purpose of this invention is to improve the semen collection rate during ejaculation.

[0009] Problem-solving device

[0010] According to one aspect of the invention, a semen collection sheet is provided having a front surface on which semen adheres and a rear surface having a fixing portion. When the semen collection sheet is unfolded, a reservoir portion is formed to collect the semen adhering to the front surface.

[0017] Figure 5 This is a picture of semen collection tablet 1C (folded state) before use. Detailed Implementation

[0018] <Example> An overview of the semen collection tablet 1 and its use will now be described.

[0019] Figure 1 This is a diagram showing the state of the semen collection tablet 1 before use (e.g., at the time of sale); and Figure 2 This is a three-dimensional diagram showing the state of the semen collection tablet 1 in use, i.e., the state in which the user is using the semen collection tablet 1. In a clinic, at home, or other suitable environment, the user... Figure 1 The semen collection sheet 1 is unfolded as shown and fixed to the mounting surface W (wall surface, etc.) so that the reservoir portion RB formed in the unfolded state is in a vertically downward position on the sheet, as shown. Figure 2 As shown. In this fixed, deployed state, when semen adheres to the inner anterior surface (hereinafter, sometimes simply referred to as the anterior surface), the adhered semen accumulates in the reservoir portion RB. To perform the semen collection process, the user ejaculates while aiming at the target portion RA. The ejaculated semen adheres to the anterior surface and moves downward along the anterior surface under the influence of gravity, accumulating in the reservoir portion RB. Using a device such as a syringe (not shown), the user aspirates the semen that has accumulated in the reservoir portion RB and transfers the semen to a storage container (not shown), thus completing the semen collection process. The used semen collection disc 1 is discarded.

[0020] The structure and manufacturing method of semen collection tablet 1 will now be described in detail.

[0021] The semen collection sheet 1 is, for example, A4 size (297 x 210 mm). For the material used as the semen collection sheet 1, it is preferable that at least the front surface to which the semen adheres is treated to have liquid-repellent properties. That is, the front surface is treated to repel water, mud, oil, and proteins (such as those present in semen). Typical liquid-repellent treatment methods include heat-melt type, paint coating type, etc., and any such method can be used. Liquid-repellent treatment can be achieved by treating the front surface of the sheet with a fluorinated compound or silicone resin. Alternatively, polyethylene glycol can be used in combination with glucose or sucrose.

[0022] In this embodiment, any suitable known liquid-repellent treatment can be used. However, in order to achieve a non-uniform front surface structure that provides the so-called lotus effect, it is preferable to use a super-liquid-repellent material with a high contact angle with the liquid (e.g., 170° or greater) for the front surface liquid-repellent treatment.

[0023] Additionally, it is preferable that the rear surface is made of a material on which the fixing portion 12 and / or the retaining portion 13 can be easily provided.

[0024] As the material for the semen collection sheet 1, a sheet with a dual structure can be used. Such a sheet comprises a polyethylene terephthalate (PET) film with a thickness of approximately 1 μm to 30 μm (micrometers) as the back surface, and a linear low-density polyethylene (L-LDPE) film treated to be liquid-resistant with a thickness of approximately 40 μm to 100 μm as the front surface, with the two films overlapping. More preferably, the PET film has a thickness of 12 μm, and the L-LDPE film has a thickness of 75 μm. While such thickness may slightly hinder the manipulation of the reservoir portion RB (during folding or unfolding), the composite weight of the reservoir portion RB imparts stability to the unfolded reservoir portion RB. Therefore, a total thickness of approximately 50 μm to 100 μm is preferred, which allows for easy manipulation without compromising stability.

[0025] In addition, the front surface can undergo an antibacterial treatment. The physical properties, thickness, and dimensions of the sheet described are merely examples and can be appropriately determined as needed.

[0026] like Figure 1 As shown, the semen collection sheet 1 is formed by vertically folding a rectangle with sides L1, L2, L3, and L4 along the center line C and joining the sides L4 together. Figure 1 In the middle, a joint portion 11 is formed (a rectangle with width d in the figure). To form the joint, a process such as crimping, welding, bonding, or any other suitable method can be used. On the rear surface, two fixing portions 12 and two retaining portions 13 are arranged symmetrically around the center line C.

[0027] The fixing part 12 is an adhesive component such as double-sided adhesive tape, and has one surface pre-adhered to the rear surface of the semen collection sheet 1 and a protective seal attached to the other surface. In use, the user peels off the protective seal and adheres the other surface to the desired position.

[0028] The retaining portion 13 includes a sheet-shaped member, the upper half of which is adhered to the outer surface of the semen collection sheet 1, while the lower half is not adhered, and the retaining portion 13 can be pinched when the user unfolds the semen collection sheet 1 (when retained).

[0029] When using the semen collection sheet 1, the user does not need to hold the container with one hand during masturbation, and the semen collection sheet 1 can be fixed in a suitable position considering the user's height and body type, allowing the user to perform ejaculation while maintaining a relaxed posture. Furthermore, since the surface area for sperm adhesion during ejaculation is larger than that of a conventional container, sperm collection is unlikely to be affected even if the direction of ejaculation deviates slightly from the expected direction. Moreover, since the semen collection sheet 1 can be manufactured from the sheet components using a simple process, the cost of manufacturing the sheet can be kept low. Therefore, although the semen collection sheet 1 is designed for single use, it is cost-effective because it can be provided at a low cost. Furthermore, since the user can unfold and properly fix the semen collection sheet 1 by squeezing and holding the holding part 13, the risk of contamination of the collected semen with bacteria, etc., is avoided.

[0030] In recent years, there has been an increase in the number of methods where people collect sperm outside of medical facilities (at home, etc.) and inject the collected sperm into the vagina using syringes or the like (for convenience, this is referred to herein as the "syringe method"). Specifically, users purchase product sets containing syringes and plastic collapsible cups (for convenience, this is referred to herein as "syringe method kits") and inject the sperm into the vagina. However, syringe method kits are inconvenient because it is difficult to increase the size of the provided cups due to limitations in packaging size, etc. By using the semen collection sheet 1 according to the invention, since the semen collection sheet 1 is compact when folded and has a large surface area for collecting semen when unfolded, the semen collection sheet 1 is also suitable for syringe method kits.

[0031] <Example Modification>

[0032] The joining portion 11 does not need to be formed along one side of the semen collection sheet 1. For example, as... Figure 3 The semen collection sheet 1A shown has a connecting portion 11A that can be formed as an arc-shaped band extending from the lowest point on the center line C to point Q1 on the side L2 (L3). The region RE1 below the connecting portion 11A can be removed after the connecting portion 11A is formed, or it can be left as is.

[0033] Alternatively, as Figure 4 The semen collection sheet 1B shown has a connecting portion 11B that can be formed as a strip-shaped area, in which the center of the arc contacts the center of the side L4. The area RE2 below the connecting portion 11B can be removed after the connecting portion 11B is formed, or it can be left as is.

[0034] Alternatively, as Figure 5The semen collection sheet 1C shown has a connecting portion 11C that can be formed as a strip-shaped region, in which a strip-shaped portion along the side L4, a strip-shaped portion extending from the side L4 to a point on L2 (L3), and a strip-shaped portion extending from the side L4 to a point on the center line C are combined. The region RE3 below the connecting portion 11C can be removed after the connecting portion 11B is formed, or it can be left as is.

[0035] In short, in this invention, a single sheet member is sufficient to be joined to form a joint portion such that when the joint portion is unfolded, the reservoir portion (in other words, the hollow or pocket portion) forms for the accumulation of semen. The shape of the joint portion described above is merely an example and can be appropriately constructed according to the desired shape of the reservoir portion. However, it is preferred that the joint portion (i.e., the shape of the formed reservoir portion) is symmetrical about a centerline.

[0036] Preferably, such as Figure 1 and Figures 3 to 5 As shown, the reservoir portion is constructed by folding a sheet component in half and joining strip-shaped regions (11A, 11B, and 11C), which extend from a point on the fold line to a point on the overlapping side parallel to the fold line. Therefore, when the sheet is unfolded for use, semen adhering to the front surface of the sheet accumulates in the reservoir portion. The shape of the strip-shaped regions shown here is merely an example and can be appropriately constructed.

[0037] The retaining part 13 can be omitted. Even if omitted, since the engaging part 11 serves as a handle, the user can unfold the sheet without touching the inside by pinching and holding the engaging part 11 when unfolding.

[0038] The fixing part 12 can be omitted. That is, instead of the product being sold with the provided fixing part 12, the user can attach double-sided tape to the desired location. Furthermore, the shape, position, size, fixing method, and mechanism of the fixing part 12 are not limited. For example, as a method for fixing the semen collection sheet 1, instead of using adhesive, holes can be formed on each of the left and right sides of the upper end of the semen collection sheet 1, and an S-hook or other provided hook can be inserted by the user into the holes for suspension from a strip member, etc. Alternatively, the semen collection sheet 1 can be fixed by using a fixing member (such as a bracket with provided clips) for user use, without providing a fixing mechanism such as holes or adhesive sheets.

[0039] The position of the fixing part 12 depends on the strength of the material of the semen collection sheet 1, but as long as it can be maintained... Figure 2The shape shown indicates that the installation position does not need to be near the upper end of the semen collection piece 1. In this case, even if the user touches the collection surface of the piece while fixing it, from a hygiene point of view, the possibility of semen coming into contact with the area of ​​the piece touched by the user is very small. However, it is preferable that the fixing part is located as far away as possible from the center of the semen collection piece 1 (the area where semen is most likely to adhere).

[0040] The fold line can be formed along the center line C. Alternatively, the user can create a horizontal fold line. For example, by creating a horizontal fold line at the third-third position, multiple semen collection sheets 1 can be folded and packaged to achieve a compact package.

[0041] The target portion RA can be printed with markings that serve as a reference for the ejaculation direction, such as a concentric target pattern.

[0042] In short, the semen collection sheet according to the invention has a front surface to which semen is attached and a rear surface with a fixing device, and when unfolded, has a reservoir portion for accumulating the semen attached to the front surface.
