Description

[Detailed Description of the Invention] The present invention relates to an animal electrocardiograph terminal used for animal health management and disease diagnosis. More specifically, it is especially suitable for animals with hair on their skin, such as laboratory animals such as dogs, cats, rabbits, and guinea pigs, domestic animals such as cows, horses, and sheep, various zoo animals, race horses, and other pet animals. Concerning a valid electrocardiograph terminal.

Electrocardiograms are already commonly taken for health management and disease diagnosis of these types of animals.
As shown in Figure 1, hold an injection needle 2 with one end that has a connection part 1 to the electrocardiograph in one hand, pinch the skin of the animal with the other hand, and pierce the skin with the needle 2. The stopper rubber 3 was fixed to the protruding end of the needle. However, this type of injection needle has the disadvantage that when it is inserted into the skin, the needle easily bends, making it impossible to use it again, resulting in a large amount of waste. Another drawback is that after the needle has been pierced into the skin, a stopper rubber must be fixed to the tip of the needle each time in order to prevent the needle from coming out of the skin.

Furthermore, as shown in FIG. 2, a device in which the terminal is configured in the form of an alligator-shaped clip is also known.
This terminal connects a pair of clip bodies 3 and 4 to a pivot 5.
The clip bodies 3 and 4 have tooth-like protrusions 6 and 7 on their opposing surfaces at their distal ends. These protrusions 6 and 7 bite the skin from above the animal's hair. However, with this type of hair, the hair is caught between the protrusions 6 and 7, making it difficult for the protrusions to penetrate into the skin. However, the disadvantage is that the response is slow and it is difficult to detect wavelengths. Therefore, this type is rarely used at present.

This invention was developed to solve the various problems mentioned above, and when used, the terminal needle of the animal electrocardiograph can be reliably penetrated into the tough skin of the animal with one hand operation, and To provide a highly safe animal electrocardiograph terminal that can reliably prevent the risk of bending or breaking when not in use or in use.

Hereinafter, preferred embodiments of the present invention shown in the drawings will be described in detail.

The electrocardiograph terminal 10 includes clip bodies 11 and 12. The entire clip body 11 is formed into a substantially arched shape, and the left end side of the clip body 12 in FIG. 3 is slightly bent outward. Semicircular arc-shaped connecting plates 13 and 14 are integrally formed and protruded approximately at the center between both ends of the clip bodies 11 and 12.
These connecting plates 13 and 14 consist of a one-to-one pair,
A connecting plate 13 of the clip body 11 is freely inserted between the connecting plates 14 of the clip body 12, and is pivotally connected by a pivot 15.
A spring 16 is wound around this pivot 15, and exerts an acting force so that the distal ends of the clip bodies 11 and 12 approach each other. A handle cover 17 is attached to the right end of the clip main body 11 in FIG. 3, and a hole 18 of an appropriate diameter is drilled in the left end as necessary. Clip body 1
1, a cushion body 19 is integrally attached to the inner surface of the left end side by caulking or other suitable fixing means as necessary. The cushion body 19 is preferably made of a relatively soft material such as rubber or styrofoam.

A needle 20 is integrally attached to the inner surface of the tip (left end in FIG. 3) of the clip body 12 by, for example, soldering or other suitable fixing means. The needle 20 is preferably made of a rust-resistant material, such as a hard stainless steel material. The entire needle 20 is slightly curved, and when the distal ends of the clip bodies 11 and 12 are brought close to each other, the distal end of the needle 20 enters the cushion body 19,
Furthermore, it is preferable to take care not to damage the tip of the needle 20 by penetrating into the hole 18.

A stopper 21 is provided on the inner surface of the clip body 11 at approximately the center thereof. The tip of the stopper 21 comes into contact with the inner surface of the clip body 12 to prevent the clip bodies 11 and 12 from coming closer than a certain level. In other words, the approach of the needle 20 to the clip body 11 is restricted, the penetration of the needle 20 into the animal's skin is restricted, and the degree of penetration of the needle 20 into the cushion body 19 is restricted. needle 2
It is designed to protect the tip of the 0 and prevent it from penetrating into the animal's skin. The third part of the clip body 12
In the figure, an electrocardiograph terminal insertion port 22 which also serves as a handle is provided at the right end portion, and this insertion port 22 is connected by a transmission member 23 provided on the inner surface of the clip body 12.

Next, the function of the terminal will be explained.

The handle 17 and the insertion opening 22 are grasped with the fingertips of one hand, and force is applied in the direction toward each other to open the distal ends of the clip bodies 11 and 12. Then, the needle 20 moves away from the cushion body 19, and an opening 24 is formed between the needle 20 and the cushion body 19. However, the clip bodies 11 and 12
If you release the above acting force by lightly pressing the tip of the spring 16 against the animal's skin, the spring 16
As a result, the distal ends of the clip bodies 11 and 12 are brought close to each other, the needle 20 penetrates the skin, and its distal end enters the cushion body 19. Therefore,
The needle 20 is firmly gripping the skin, and an electrocardiogram can be taken in this state.

As explained above, with the present invention, the needle can be fixed by simply grasping the terminal with one hand and piercing the terminal needle into the animal's skin, so unlike conventional injection needles, it is not necessary to use both hands to operate the needle. Since there is no such thing, the work is simplified. The needle can be securely fixed in the skin by simply inserting it into the skin with one hand, which eliminates the tedious work of fixing a stopper rubber to the tip of the needle, which was previously required. No longer needed. Furthermore, since the terminal needle is securely fixed within the skin, accurate wavelengths can be obtained without slowing the response or causing noise in the waveform due to loosening of the terminal, unlike in the past. Furthermore, the needle has a fang-like tip and is entirely arcuate, and since the needle tip is inserted into the cushion body, when the needle tip pierces the animal's tough skin, the bow-shaped needle remains intact. The needle is inserted smoothly into the skin with very little resistance, and then guided out of the skin.When not in use or in use, the needle tip is inserted into the body of the cushion, and the needle tip enters the hole. The degree of penetration of the needle tip is regulated by a stopper formed on the grip body, and the needle tip is protected from being exposed beyond a certain level, thereby reliably preventing the needle tip from bending or becoming damaged.

In the embodiment of the present invention, a case has been described in which the needle 20 is integrally fixed to the clip body 12 side by soldering, but the present invention is not necessarily limited to that structure. Main body 1
It is also possible to replace the needle 20 by forming a strip-like needle integrally with the tip edge of the needle 2 and bending it vertically. Alternatively, a slit may be made in the distal end of the clip body 12, and the slit-like needle formed by the slit may be raised vertically to perform the same function as the needle 20 described above. good. Further, although the case where the stopper 21 is provided on the clip main body 11 side has been described, the stopper 21 may be provided on the clip main body 12 side. In this way, the present invention does not deviate from the scope of claims for utility model registration.
Various changes may be made to the detailed structure of the embodiments.
