Description

The present invention relates to a method for securely fixing and placing a needle-like injection device for injecting a liquid into an animal body using the needle-like injection device, and a holder (holder, clamp) used in this method. It is about.
In particular, the present invention relates to a method for securely fixing and placing an injection needle, for example, a venous needle, in a venous blood vessel of an animal, and a holder used in this method.

2. Description of the Related Art Supplying, introducing, and injecting liquids such as liquid medicines, nutritional supplemental liquids, blood, and the like to animals using tubes such as injection needles and catheters is widely performed in the fields of fluid replacement, infusion, blood transfusion, and the like. Since such operations require a certain amount of time, the animal is generally held at the time of liquid injection, and a tube such as an injection needle or a catheter is fixed on the surface of the animal's body.
On the other hand, cattle breeding methods have changed in recent years, and it has become difficult to reliably retain cattle due to fluid replacement and the like in free stall, free burn and the like.

In the conventional indwelling needle, an injection needle is inserted into a venous blood vessel, the needle is removed, and a plastic tube outside the needle is placed in the blood vessel. This indwelling method is fixed by the frictional force between the surface of the plastic tube to be indwelled and the skin and subcutaneous tissue, and the fixing force may be insufficient in the animal skin that moves around.
Therefore, a liquid injection means such as an injection needle or a catheter is fixed to the body surface with an adhesive tape (see Patent Document 1 below), a clip, or the like during the supply, introduction, and injection of the liquid.
US Patent 2002 / 0177838-A1 Specification

  However, it is easy to fix the adhesive tape, and it is difficult for an animal whose body surface is covered with long hair to fix it with the adhesive tape, and it can be easily removed even if it can be bonded.

In addition, the method of fixing the replacement fluid pipe part to the skin with a clip does not fix the injection needle, and the animal is constantly moving, and the skin is partially vibrated to drive away the blood-sucking insects. In this method, the injection needle may come off the venous blood vessel.
The following literature proposes a method of fixing a catheter on a body surface with a flat clamp.
US Patent No. 2005 / 54985-A1

  However, even in this patent, the clamp itself is fixed on the body surface by a mounting pad coated with a pressure-sensitive adhesive.

  An object of the present invention is to provide a method for securely placing and holding a needle-like injection device on the body surface of an animal by a very simple and safe method, and a holding device used in this method.

A first object of the present invention is a method of fixing and placing a needle-like injection device for injecting a liquid into an animal's body on the surface of the animal's body. After inserting the implement, the needle-like infusion device is applied by applying a force to grasp the animal body surface tissue portion between the liquid injection site and the needle-like infusion device using the grasping member. Is fixed and placed on the body surface tissue of an animal.
The above force can be applied by a spring force.

A second object of the present invention is a needle-like infusion device for injecting liquid into the body of an animal, and an engagement portion for the needle-like infusion device, and the needle-like infusion device and liquid injection on the animal body surface A grasping member (holder) having a biasing means for applying a force to the needle-shaped injection device so that the body surface tissue portion of the animal between the region and the region is grasped. It exists in the fixing tool for fixing the needle-shaped injection tool which inject | pours a liquid on the body surface structure | tissue of an animal.
The biasing means can be a spring.

The “needle-like injection device” means any hollow needle-like member such as an injection needle, an indwelling needle, or a catheter used for injecting a liquid into the body of an animal.
The above “liquid” means any liquid that is injected into the body of an animal for the purpose of prevention, treatment, research, experiment and the like. The present invention is useful in the application of water, nutrients, liquid medicine, blood and other replacement fluids, and blood transfusion.

The present invention can be applied to all animals, but is particularly useful for mammals, particularly livestock, sports animals, laboratory animals, pets such as cattle, goats, sheep, horses, pigs, cats, dogs and the like. Although the present invention is primarily directed to animals, the method and apparatus of the present invention applied to humans does not depart from the scope of the present invention.
The “site to be injected” is a veterinary place where the liquid on the body surface of the animal is to be injected, and this place can be appropriately selected by a veterinarian based on veterinary knowledge.

The “gripping member” means a “holder” that applies a force to the needle-like injection device such that the body surface tissue portion of the animal between the liquid injection site and the needle-like injection device is held.
“The force that grips the body surface tissue portion of the animal between the liquid injection site and the needle injection device” prevents the attachment position of the needle injection device from moving substantially on the animal body surface. A pressing force is applied between the needle-like injection tool and the gripping member, and this force can be applied by the biasing means. This urging means can be an elastic body made of an elastic material such as a spring or rubber, and can generally be a spring. As the spring, any spring including a leaf spring, a coil spring, a torsion spring and the like can be used, and the material of the spring can be a metal, plastic, rubber, composite material or the like. When an elastic material such as rubber is used as the urging means, the support or frame that supports the elastic material can be a rigid body.

Examples of the replacement fluid that can be supplied in the present invention include the following.
1) Calcium preparation, hypertonic glucose, isotonic Ringer sugar (mild administration is preferred)
2) Ringer's solution, 5% glucose, isotonic Ringer's sugar (replenishment of intracellular and extracellular fluid, electrolyte)
3) Halzen solution, 7% sodium bicarbonate solution (improvement of acid and base equilibrium)
4) Strong liver, nutrient 5) Hypertonic saline (maintaining circulating plasma volume)
6) Antibiotic (dissolved in Ringer's solution, 5% glucose, isotonic Ringer's sugar)

Examples of cases to which the present invention can be applied include the following.
1) Intravenous injection of replacement fluid 2) Long-term large-volume replacement fluid for dehydrated cattle (up to about 3 liters for normal replacement fluid, 5-10 liters for dehydrated cattle)
3) Calcium preparation, hypertonic glucose, mild replacement fluid for beef cattle (infusion by squeezing the stopper of the catheter is also possible)

  In general, a container containing a liquid to be injected into the animal body is fixed and supported by a fixed structure such as a hanger or pillar, and an injection tube is extended from this container, and a syringe needle and an indwelling needle are attached to the tip of the injection tube. Attach a needle-like member such as a catheter. The flow rate of the liquid supplied from the container to the needle-like member can be adjusted by a flow rate adjusting device used as necessary.

When it is necessary to inject a liquid over a certain period of time, the animal is generally retained. However, by using the present invention, the injection needle can be reliably fixed in the blood vessel even if the normal retention is released.
For grazing livestock, zoo animals, laboratory animals, etc., a suitable means, for example, a band or the like is used to attach and fix a container containing a replacement fluid to a part of the animal body, for example, the back, and the method of the present invention. By using a fixture, the injection needle can be reliably fixed in the blood vessel without any retention, and the animal can move freely.

  As this application of the present invention, the fixture of the present invention can also be used when a liquid such as blood is periodically sampled from a laboratory animal over a long period of time or when a drug is administered to a laboratory animal over a long period of time. In this case, the sampling device is preferably attached to a part of the animal body using a band or the like.

  In a first preferred embodiment of the present invention, the urging means includes two outer spring portions, a connecting shaft for rotatably connecting the vicinity of the tips of the two outer spring portions, and each of the two outer spring portions. A connecting portion that connects the end portions to each other, and an inner spring portion that protrudes from the substantially middle portion of the connecting portion toward the connecting shaft direction, and the engaging portion is formed in the vicinity of the distal end portion of the inner spring portion. It is an engagement hole with a needle-shaped injection tool.

Applied force). The torsional elasticity described above is obtained by connecting the vicinity of the tips of two outer spring portions parallel to each other with a connecting shaft so as to be rotatable, and the tips of the two outer spring portions are inside (each tip of the two outer spring portions). Between the engaging portion of the inner spring portion with the needle-like injection tool and the tip connecting shaft portion of the two outer spring portions when the vicinity is reversed to the side that is warped to the injection needle side with respect to the position when the vicinity is not connected A predetermined pressing force is generated.

  The magnitude of this force can be appropriately determined by those skilled in the art by selecting the dimensions and materials of the outer spring portion and the inner spring portion. The holder is preferably made of a stainless steel plate having spring characteristics that can be easily sterilized and mass-produced at a low cost.

  In a second embodiment of the present invention, the holder of the present invention is made of a plastic material having elasticity or resilience. This type is advantageous when reducing costs or making a disposable holder. It is desirable to reduce environmental pollution and load by using a degradable plastic material such as polylactic acid copolymer.

  The hole through which the injection needle is formed at the distal end portion of the inner spring portion may be a closed hole, but may be a hole with one end opened. By doing so, the veterinarian inserts the injection needle into the bovine (1) body surface in the usual manner, and then drops the injection needle into the hole through the opening of the open hole, so that the holder is placed on the bovine body surface. Can be fixed.

  The disposable holder can be manufactured from a plastic material by a molding technique such as injection molding. The holder of the present invention can be stored in a flat state before use and assembled into a three-dimensional shape at the time of use.

In this fourth embodiment, the entire liquid injection site on the animal body surface is covered with a rigid plastic cover. The entire assembly composed of the bubble storage part (octopus tube) and the injection needle mounting part is accommodated inside the injection tool holding member from above. The extension on one side surface of the syringe holding member is an elastic belt, and the tip of the elastic belt is pulled out of the plastic cover through a slit formed in the plastic cover. The relative position between the elastic belt and the plastic cover can be adjusted by using a ratchet mechanism or the like. The elastic belt can be made of any material such as elastomer, rubber, laminated material, composite material and the like.

  Hereinafter, several embodiments for fixing and placing a needle-like injection device on the surface of a body such as an animal by the method and apparatus of the present invention will be described.

FIG. 1 is a conceptual diagram of the first embodiment of the present invention. In this embodiment, the injection needle (2) is fixed and placed on the body surface of an animal (bovine in the illustrated embodiment) (1) using the holder (10) of the present invention. The injection needle (2) is supplied with replacement fluid via a bubble reservoir (octopus tube) (4) and a tube (tube) (3). The end (not shown) of the tube (3) is connected to a container containing a liquid such as a replacement fluid, and this container is generally fixed and supported by a fixed structure such as a pillar.
[FIG. 2] is an enlarged view of the fixture of the present invention shown in [FIG. 1], and [FIG. 3] is a conceptual perspective view of the fixture of the present invention shown in [FIG. 2] when viewed from the opposite side. (Note that FIG. 3 shows a state in which the fixture of the present invention is removed from the cow (1)).
FIG. 4 is a conceptual cross-sectional view of the fixture of the present invention taken along line XX in FIG.

  In the holder (10) of the first embodiment of the present invention shown in [FIG. 1] to [FIG. 4], the body surface tissue and / or skin portion (1 ′) of the bovine (1) is connected to the injection needle (2). It is securely held between the outer spring portions (11, 12) and the injection needle (2) does not come out of the cow (1) carelessly. That is, the injection needle (2) by frictional engagement between the bodily (1) body surface tissue and / or part of the skin, the injection needle (2), and the tip of the outer spring part (11, 12).
