Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a simple remover that efficiently removes filariae living in the blood and lymph nodes.

(Conventional technology) Heartworms are parasitic nematodes, and adult worms are thread-like (about 80 mm in females and 40 mm in males), and usually hide in lymph vessels or lymph nodes, especially in the scrotum and lower leg, and are localized in lymph nodes. This causes dilation of the ducts and edema, which is accompanied by swelling of the lymph nodes and proliferation of connective tissue in the skin, resulting in so-called elephantiasis. It is also known that animals such as dogs are infested with many threadworms. Spatonin is usually administered to remove the heartworms hidden in the body, but elephantiasis and scrotal hydrocele require surgical treatment.

(The problem that the invention aims to solve) However, surgical treatment always involves risks;
Moreover, there was the problem of requiring hospitalization.

Therefore, an object of the present invention is to provide a simple remover that can efficiently remove filamentous worms latent in lymph nodes or blood without surgical treatment.

(Means for Solving the Problems) The simple remover of the present invention connects a second joint pipe to the base of a first joint pipe connected to a tube to which a syringe needle is attached; A syringe barrel is inserted into the base of the tube, and a check valve is provided at the tip of the second joint tube and a second branch tube provided in the second joint tube,
The second branch pipe and the first branch pipe provided in the first joint pipe are connected by a tube through a passage means, and the body fluid is sucked out into the syringe barrel by operating the piston of the syringe barrel. This is a simple device for removing heartworms, which is characterized by intermittently returning the body fluid from which the heartworms have been removed.

(Function) The simple threadworm remover of the present invention is provided with a check valve at the tip of the second joint pipe and the second branch pipe, and the first branch pipe provided at the first joint pipe. By connecting the first and second branch pipes with a tube through a passage means, it is possible to easily draw out the body fluid from the body and return the body fluid from which the filamentous worms have been removed by simply operating the piston of the syringe barrel.

(Embodiment) Next, an embodiment of the simple threadworm remover of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of the simple remover, and FIG. 2 is a partially sectional view showing the structure of the joint tube. A tube 8 is connected to the tip of the first joint tube 7, and an injection needle 4 that is inserted into the body is attached to the tip of the tube. A second joint pipe 5 is connected to the base of the first joint pipe 7, and a syringe barrel 1 in which a piston 2 is fitted is connected to the base of the second joint pipe 5.
The tip of the tube is inserted. A first branch pipe 10 provided on the first joint pipe 7 and a second branch pipe 9 provided on the second joint pipe 5 are connected by a tube 6 via a passage means 3. Also, check valves 11 and 11' are attached to the tip of the second joint pipe 5 and the second branch pipe 9, respectively, and these two joint pipes 5,
7 and branch pipes 9 and 10 are housed in a housing 13.

The check valves 11 and 11' fitted into the tip of the second joint pipe 5 and the second branch pipe 9 are flexible semi-cylindrical bodies, and in FIG. It is arranged so that the inside of the tip and the outside of the second branch pipe 9 are concave. The above-mentioned check valve may have a structure other than the above-mentioned one, for example, one in which a flexible tube is formed into a flat shape, or one in which a convex part of a flexible hemispherical surface is cut.

The passage means 3 is a closed container having an inlet and an outlet for body fluids and containing a material 12 such as non-woven fabric or cotton inside.

In FIG. 2, a check valve made of a flexible semi-cylindrical body is installed inside the tip of the second joint tube 5 and inside the second joint tube 5 so that the body fluid sucked into the syringe barrel is returned to the human body via the passage means 3. Although it is arranged so as to be concave on the outside of the branch pipe 9, it may be arranged in the opposite direction. In that case, the body fluid is aspirated into the syringe barrel via the overflow means.

When removing filamentous worms using the simple remover described above, the injection needle 4 is attached to the tip of the tube 8 which has been filled with physiological saline in advance, and the injection needle is inserted into a blood vessel or lymphatic vessel. Next, when the piston 2 of the syringe barrel 1 is pulled out, negative pressure is created between the first and second joint tubes 7 and 5 and the inside of the syringe barrel 1, and blood or lymph fluid (hereinafter referred to as body fluid) is sucked out by this negative pressure, and the second A check valve 11 attached to the tip of the joint pipe 5 of
is opened, the check valve 11' attached to the second branch pipe 9 is closed, and the liquid is sucked into the syringe barrel 1. Next, when the piston 2 is pushed in, the body fluid sucked into the syringe barrel is pushed out to the second joint pipe, and this flow opens the check valve 11' attached to the second branch pipe 9.
When the check valve 11 attached to the tip of the second joint tube is closed, the body fluid is sent from the tube 6 to the passage means 3, and the material 12 contained in the passage means 3 is used to form filaments contained in the body fluid. Insects are removed. The body fluid from which the heartworms have been removed is returned to the body through the tube 8 and the injection needle 4.

By repeating the operation of the piston 2 of the syringe barrel 1, body fluid is intermittently sucked out and the body fluid from which filamentous worms have been removed is returned. By repeating this operation for a predetermined period of time, threadworms contained in body fluids can be efficiently removed without surgery.

(Effects of the invention) As described above, the simple threadworm remover of the invention can efficiently suck out body fluids and return the body fluids from which threadworms have been removed simply by operating the piston of the syringe. The simple threadworm remover of the present invention is particularly suitable for removing threadworms living in the blood vessels of animals such as dogs.
