Description

  The present invention relates to a tick remover that removes ticks bitten on animals such as pets.

  When ticks are infested in animals such as dogs and cats, for example, infectious diseases such as babesiosis and anemia cause, it is necessary to remove ticks. Conventionally, when removing ticks, the body of the ticks is pinched and pulled away from the animal by picking it with hands or tweezers.

  However, when ticks are parasitic on animals, the animal's skin is firmly pinched between the jaws, and when ticks are removed, the whole tick is securely retained by the method of picking with hands or tweezers. In some cases, a part of the tick's body remained attached to the animal, and there was a risk of suppuration from the bite.

  On the other hand, if the tick is firmly held to hold the tick, the pathogenic bacteria parasitic in the tick body flow into the animal's body from the bite part together with the sucked blood and tick body fluid by compressing the torso, and the animal is There was a risk of infection. In addition, ticks were crushed and blood that had been sucked might leak from the ticks.

  The present invention has been made to solve the above problems, and an object of the present invention is to provide a tick catcher that can remove ticks hygienically and reliably.

  The object of the present invention is to provide a pair of clamping members each having a receiving portion at the tip, each of the receiving portions comprising a hemispherical cup member having a contact surface on the periphery of the opening. The contact is achieved by a tick catcher in which a holding space is formed inside.

  Moreover, it is preferable that the width | variety of the said contact surface in the front end side of the said accommodating part is 0.1-0.9 mm.

  Moreover, it is preferable that the pair of sandwiching members are connected in a tweezers shape at a base end portion.

  According to the tick removing tool of the present invention, ticks can be removed in a sanitary and reliable manner.

  Hereinafter, actual forms of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a plan view of a ticks removing tool 1 according to an embodiment of the present invention, FIG. 2 is a cross-sectional view of the ticks removing tool 1, and FIG. 3 is a perspective view showing a main part of the ticks removing tool 1. It is.

  As shown in FIG.1 and FIG.2, the tick removal tool 1 is equipped with a pair of clamping members 2 and 2 which each have the accommodating parts 4 and 4 at the front-end | tip. Examples of the material of the tick removal tool 1 include iron, aluminum, copper, titanium and alloys thereof, steel, brass, rubber, plastic, ceramics, bamboo, and the like, and a composite material obtained by combining these materials may be used. .

  The pair of sandwiching members 2 and 2 are overlapped so that a long and narrow plate-like member having elasticity branches in a bifurcated manner from a base end portion 3 provided on the opposite side of the housing portions 4 and 4. It is connected so that the elastic force can be obtained in the direction away from each other when the two are pressed close to each other. In the present embodiment, the pair of sandwiching members 2 and 2 are configured by stacking two plate-like members, but may be formed integrally by folding an elongated plate-like member at the center. Good.

  Moreover, the clamping members 2 and 2 are provided with a grip portion 12 having a plurality of protruding slip stoppers 13 on the surface side of the central portion in the longitudinal direction. The shape of the anti-slip 13 is a rectangular shape in the present embodiment, but is not particularly limited as long as it can prevent slipping when the gripping portion 12 is gripped. It may be formed into a concave shape by pressing 2 with a convex mold.

  The accommodating parts 4 and 4 are each formed of a hemispherical cup member having contact surfaces 15 and 15 on the periphery of the opening, and a holding space is formed inside when the contact surfaces 15 and 15 contact each other. Here, the “hemisphere” may be a curved surface having a smooth surface, and includes both a semi-spherical shape and a semi-elliptical sphere shape. In the case of the semi-elliptical sphere shape, the accommodating portions 4 and 4 are preferably configured such that the major axis of the ellipse is along the longitudinal direction of the sandwiching members 2 and 2. The diameters and depths of the accommodating portions 4 and 4 are not particularly limited as long as they can be securely held in the holding space without crushing the ticks that have become saturated and enlarged, and can be used practically. When the housing parts 4 and 4 are semi-elliptical spheres, the major axis is preferably 7.5 mm to 16 mm, and more preferably 9.0 mm to 14 mm. Further, the short warp is preferably 7.5 mm to 14 mm, more preferably 8.0 mm to 12 mm. Further, the depth is preferably 2.5 mm to 6.0 mm, more preferably 3.0 mm to 5.0 mm.

  The clamping members 2 and 2 have flexibility, and are slightly curved so as to come into contact from the front end side when the contact surfaces 15 and 15 are brought into contact with each other by being pressed.

  Next, a method for removing ticks using the ticks removing tool 1 configured as described above will be described.

  In the state where the ticks are biting on the skin of the animal, the ticks are held between the accommodating parts 4, 4 by pressing the grip part 12 and bringing the accommodating parts 4, 4 close to each other. At this time, the jaw body portion of the tick is sandwiched between the contact surfaces 15 and 15 on the distal end side of the housing portions 4 and 4, and the body portion is held in the holding space formed between the housing portions 4 and 4. Then, ticks are removed by pulling them away from the animal while holding ticks.

  According to the ticks removing tool 1 of the present embodiment, since the accommodating parts 4 and 4 are hemispherical, the ticks are surely removed without damaging the animal skin regardless of the direction of the ticks removing tool 1 relative to the animal skin. can do. Further, the accommodating portions 4 and 4 are configured to form the holding space by bringing the contact surfaces 15 and 15 into contact with each other, and the ticks are held in the holding space. The body part of the tick can be securely clamped, but the body part of the tick is not compressed, so it can be securely held without crushing the tick, and the body fluid of the tick and blood that has been sucked are not leaked due to the pressure. Tick can be removed.

  Further, since the pair of sandwiching members 2 and 2 are connected in a tweezers shape, by loosening the pressing force of the gripping portion 12, it is possible to drop the ticks held away by the elastic force. Tick can be easily removed without touching it. The spring pressure of the tick removal tool 1 is not particularly limited as long as it has elasticity, but is preferably 0.3 to 0.6 kgf from the viewpoint of reducing the user's mental and physical fatigue. . Here, the spring pressure of the ticks removing tool 1 is such that the ticks removing tool 1 is placed on a flat surface, and one clamping member 2 is brought close to the other clamping member 2 as shown by arrow F in FIG. This is expressed by a force that presses the central portion of the clamping member 2 and presses the clamping member 2 when the tips of the accommodating portions 4 and 4 come into contact with each other.

  In the accommodating portions 4 and 4 of the present embodiment, if the width of the abutment surface 15 on the tip side is too narrow, the tick is cut when it is sandwiched between the abutment surfaces 15 and 15, and part of the ticks are animal skin May remain while biting. On the other hand, if the width is too wide, the tick's torso may be squeezed and crushed, making it impossible to remove it in a sanitary manner. Therefore, the width of the contact surface 15 on the distal end side of the accommodating portion 4 is preferably 0.1 to 0.9 mm, more preferably 0.2 to 0.7 mm, and more preferably 0.3 to 0.3 mm from the examples described later. 5 mm is more preferable.

  As mentioned above, although one Embodiment of this invention was described, the specific aspect of this invention is not limited to the said embodiment.

  For example, in the present embodiment, the pair of sandwiching members 2 and 2 are connected in tweezers at the base end portion 3, but if the ticks can be securely held by the storage portions 4 and 4, The configuration is not particularly limited and may be separate from each other. Alternatively, as shown in FIG. 4, the gripping portions 12 and 12 are provided on the base end portions 3 and 3, respectively, and the rotation shaft 16 is provided. The structure supported so that rotation was possible. According to such a configuration, by inserting fingers into the gripping portions 12 and 12 and opening each other, the holding members 2 and 2 are rotated to open the housing portions 4 and 4. Thereafter, the gripping portions 12 and 12 are closed to each other to close the housing portions 4 and 4 to hold the ticks between the housing portions 4 and 4.

  Moreover, as shown in FIG. 6, the accommodating parts 4 and 4 may be coated with a coating 20 such as plastic on the surface, or may be plated. Further, the coating film 20 may contain an antibacterial agent or an insecticide.

  Hereinafter, the present invention will be described in more detail with reference to Examples and Comparative Examples. However, the present invention is not limited to this embodiment.

Example 1
In order to confirm a preferable range of the width of the contact surface 15 on the distal end side of the accommodating portion 4, the tick larvae, nymphs and adult larvae are indicated by the hatched portions in FIG. Moreover, the test which presses a tick was done, adjusting the width W of the pressing surface of a tick.

  Using a tick in a saturated state, one end (right end in FIG. 5) of the pressing surface indicated by oblique lines was pressed in a direction perpendicular to the paper surface in a state where it coincided with the mouth of the tick. This was repeated with the width W of the pressing surface increased until the ticks were crushed.

その結果、表１に示すように、マダニの幼虫については、押圧面の幅Ｗを１.００ｍｍにしたときに潰れて、体液や吸血した血液が漏出した。一方、若虫及び成虫については、押圧面の幅Ｗを１.００ｍｍにしても潰れなかった。また、マダニの幼虫は、押圧面の幅Ｗを０.７０ｍｍにしても潰れなかった。

As a result, as shown in Table 1, the tick larvae were crushed when the width W of the pressing surface was set to 1.00 mm, and body fluid and blood sucked were leaked. On the other hand, nymphs and adults were not crushed even when the width W of the pressing surface was 1.00 mm. The tick larvae were not crushed even when the width W of the pressing surface was 0.70 mm.

  From this result, it can be confirmed that the width of the contact surface 15 on the distal end side of the accommodating portion 4 is preferably 0.90 mm or less, and more preferably 0.70 mm or less in order to remove ticks without sacrificing. It was.

Example 2
Using the ticks removing tool 1 (Example) and general tweezers (Comparative Example) shown in FIG. 1, ticks biting the animal skin were removed by three testers.

  The tick removal tool 1 has a long diameter, a short diameter and a depth of 10.3 mm, 8.5 mm and 3.1 mm, respectively, and a width of the contact surface 15 on the tip side is 0.2 mm. It was.

  In addition, tweezers having a tip portion width of 2.0 mm were used.

  Moreover, the ticks used in the development stages of larvae, nymphs and adults were used. The total length, width, and height of ticks used in the test are shown in Table 2 according to whether they are unsucked or saturated. As shown in FIG. 5, the total length L is the length from the tip of the mouth of the tick to the end of the trunk, the width B is the length in the direction perpendicular to the body axis of the tick, and the height is tick Is the length from the ground to the top when is placed on the ground.

各試験者とも各発育段階のマダニについて、実施例及び比較例により、それぞれ５回の反復試験を行い、除去時間、操作回数及び落下率を測定した。ここで、除去時間は、マダニを除去するのに要した時間であり、操作回数は、マダニの除去を試みた回数であり、落下率は、マダニを除去した後に誤って落とした割合である。除去時間及び操作回数は、全試験（計４５回）の平均値を求めた。

For each tester, the tick at each developmental stage was subjected to five repeated tests according to the examples and comparative examples, and the removal time, the number of operations and the drop rate were measured. Here, the removal time is the time required to remove ticks, the number of operations is the number of attempts to remove ticks, and the drop rate is the rate of accidental dropping after removing ticks. For the removal time and the number of operations, an average value of all tests (total 45 times) was obtained.

その結果、表３に示すように、マダニ取り具１（実施例）は、除去時間、操作回数及び落下率共に、ピンセット（比較例）より低い値を示しており、マダニを容易かつ確実に除去できることが確認できた。

As a result, as shown in Table 3, the tick removal tool 1 (Example) has a lower value than tweezers (Comparative Example) in terms of removal time, number of operations and drop rate, and easily and reliably removes ticks. I was able to confirm that it was possible.
