Summary of the invention The present invention is an extremely simple and reusable tissue or mucus sample collection device that When a woman removes tissue or mucus from the cervix or vaginal fornix for examination and examination. It pertains to what makes it possible to obtain.

This device has an outer protective sleeve to provide the user with guidance on proper insertion depth. A guard ring placed on the protective sleeve and a cotton bag for collecting the sample. It has a telescoping insertion sleeve that frictionally carries the rod or scraper. This device is extremely simple in its design and easy to use.

Brief description of the drawing FIG. 1 is a perspective view of the device of the invention in an exploded state.

FIG. 2 shows a side view of the device of FIG. It is a front view.

Detailed description of the invention Referring now to the drawings, tissue or mucus sample collection device 10 is shown with an outer protective sleeve. 11, guard ring 15, telescopic insertion tube 20, strut ring 25 and tissue or It has a mucus sample collection member 30.

As used throughout the specification, the term "cervical" refers to a mucus sample. When used to refer to a mucus sample obtained from the suprabrachial area (vaginal fornix) should be understood to include.

The protective sleeve 11 has a low coefficient of friction, is less irritating to human skin, and Semi-rigid polymers with relatively low liquid absorption properties, such as polyvinyl chloride and polysol N, j? IJ ethylene, polyethylene terephthalate, IJF [ester, terephthalate] A fluorocarbon is an elongated cylinder or tube preferably formed from nylon. . The protective sleeve 11 has its tip 12 inclined at an angle of 15° to 45° from the horizontal plane. It is heat treated to give it a gentle curvature along its entire length so that it is beveled. is preferable. The inclination of the tip 12 from the horizontal plane corresponds to the anatomy of the cervix in relation to the vaginal cavity. Due to the structure of the cervix, it is rounded from the cervix. In the heat treatment process, the sleeve 11 It is gently tapered along its entire length as clearly seen in the drawing. The tip 12 is then stretched to have a significantly reduced diameter. resulting tip The reduced diameter of 12 particularly reduces the risk of cervix leakage due to intravaginal body fluids during insertion of device 10. Helps minimize mucus contamination. In addition, the protective sleeve 11 can be shaped into a desired shape. Can be injection molded. Moreover, only the tip portion of the protective sleeve 11 is inclined at a desired angle. It is understood that it may be a straight cylinder or straight tube, and that such configurations are contemplated. There will be.

A guard ring 15 formed of a suitable polymeric material slides along the protective sleeve 11. A tight friction fit over the protective sleet for movement. Guard ring 15 is the vaginal cavity along said sleeve 11 since it serves to limit the insertion depth of the device 10 therein. Movement of the guard ring 15 is achieved only by some manual effort.

The insertion sleeve 20 is also an elongated cylinder made of the same material as the protective sleeve 11. It's a tube. As shown in the drawings, the insertion sleeve 20 is connected to the protective sleeve 11. The protective sleeve 11 is adapted to telescopically fit and slide within the protective sleeve 11. It also has a slightly smaller outer diameter than its inner diameter.

A stop ring 25 formed from a suitable polymeric material is also attached to the protective sleeve 11. It is a tight friction fit onto the insertion sleeve 20 in the same manner as the guard ring 15.

Stop ring 25 is used to collect cervical tissue or mucus sample from tip 12 It works to limit the prominence of 0.

As seen in FIG. 2, the cervical tissue or mucus sample collection member 30 is , the ends of which form the sample collection tip 32 , cotton, rayon, polyester or is a slender, elongated material coated with a flexible soft elastic fiber material such as calcium alginate. It is illustrated as a double ended swab with a semi-rigid rod 31. Only one tip 32 is used to collect mucus samples. The other tip 32 is a sample collection member. 30 inside the insertion sleeve 20 by force of friction. .

The end of the sample collection member 30 that is inserted into the insertion sleeve 20 is as shown. For example, the rod 31 can have a larger diameter. It will be readily apparent to the reader that, alternatively, an elastic collar can be placed on the rod end. It would be obvious. A sample collection member 30 is used to collect a tissue sample. When appropriate, the tip of the sample collection member will be shaped like a scraper.

A handle member 35, illustrated as a ring, is attached to one end of the insertion sleeve 20. In order to guide the insertion sleeve 20 into the protective sleeve 11, the device 10 is used to manipulate the sample collection member 30 within the insertion sleeve 20 during use. Ru.

Insert the sample collection member 30 into the insertion sleeve 20 and remove the insertion sleeve 20. After assembling the device 10 by placing it in the protective sleeve 11, the stopper The tip 32 of the sample collection member 30 is placed along the insertion sleeve 20 and 12 so as to protrude only slightly. Then, the insertion sleeve 20 is inserted into the vagina. In order to prevent contamination of the tip 32 by internal body fluids, it is n))) be retreated. The device 10 then continues until the tip 12 contacts the uterine head. It is inserted into the vaginal cavity. Further insertion of the device 10 into the vaginal cavity is then prevented. To prevent the possibility of injury to the user, the guard ring 15 should not come into contact with the vaginal opening. The sea urchin is moved.

Of course, if the device 10 has been previously used to collect a cervical sample. , the guard ring 15 is already in the desired position on the protective sleeve 11. There will be. The insertion sleeve 20 is then inserted into the distal end 32 of the sample collection member 30. Move the handle forward until it assumes the predetermined "in use" position shown in Figure 2. The material 35 is pushed into the protective sleeve 11 . Then, the handle member 35 It may be rotated gently and thus a mucus sample may be collected. Insertion sleeve 20 is retracted a short distance and then the device 10 is withdrawn.

During the entire insertion and withdrawal process, the protective sleeve 11 protects the insertion sleeve 20 and especially the sample. The tip 32 of the collection member 30 is covered. The insertion sleeve 20 is separated from the protective sleeve 11 Completely withdrawn and the collected mucus samples are then disposed of for examination and testing. can be implemented.

After each use, the device 10 is thoroughly cleaned by washing with soap and water, and maintained in a condition ready for reuse. If a mucus collection swab was used, the The sample collection member 30 is discarded. If the scraper format was used, it It is washed before being reused.
