Description

Technical Field

[0001] The utility model relates to the technical field of veterinary medical instruments, in particular to a blood sampling positioning device for animals. Background Art

[0002] At present, the commonly used veterinary blood collection method is that one breeder holds the animal's body to prevent the animal from moving around, and another person holds the animal's head to prevent shaking during blood collection. At this time, the veterinarian can feel for the animal's jugular vein, press the animal's jugular vein to make the blood vessel bulge, and then insert the needle obliquely into the blood vessel to draw blood. This blood collection method requires the assistance of multiple people to complete the jugular vein blood collection of the animal. Even if a single person operates with both hands, the animal's blood vessels cannot be quickly located. The veterinarian needs to grope and search, which requires a high level of experience for the veterinarian and is relatively difficult to draw blood. Utility Model Content

[0018] The utility model will be further described below in conjunction with the accompanying drawings.

[0019] Depend on Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the utility model includes a base plate 1, a positioning block 11 arranged on one side of the base plate 1, and a limiting device arranged on the other side of the base plate 1 for limiting the movement of the animal's body, a positioning plate 12 for limiting the animal's head is adjustably provided on the positioning block 11, and a pressure plate 13 for acupuncture guidance is movably provided on the positioning plate 12.

[0020] Specifically, a placement groove 14 is provided on the positioning block 11, a fixing frame 2 is provided on one side of the positioning block 11, and a positioning plate 12 is inserted on the other side. A positioning hole 21 is provided on the fixing frame 2, and a positioning pin 15 is passed through the position of the positioning plate 12 corresponding to the positioning hole 21. The protruding end of the positioning pin 15 extends into the positioning hole 21 at the corresponding position to realize the limited fixation of the positioning plate 12 on the fixing frame 2.

[0021] A concave limiting groove 121 is provided at the lower end of the positioning plate 12 at a position corresponding to the placement groove 14 ; a concave giving way groove 22 is provided at the lower end of the fixing frame 2 at a position corresponding to the placement groove 14 .

[0022] The positioning plate 12 is fixedly connected to one end of the tension spring 23, and the other end of the tension spring 23 is connected to an arc-shaped pressure plate 13, on which a step groove 131 with upper and lower openings is provided, in which a slider 3 is provided, and on which a guide hole 31 connected to the step groove 131 is provided.

[0023] The limiting device includes a left pressure plate 41 and a right pressure plate 42 arranged on the bottom plate 1 and a fixing plate 43 which is fitted with the two pressure plates. A guide groove 16 is provided on the bottom plate 1, and guide columns 44 are provided at positions corresponding to the guide grooves 16 on the two pressure plates. The guide columns 44 at the corresponding ends extend into the guide grooves 16, so that the left pressure plate 41 and the right pressure plate 42 can move along the axial direction of the guide grooves 16 and move closer to each other to limit the movement of the animal's body; a connecting plate 5 is provided on the left pressure plate 41 and the right pressure plate 42, and a limiting hole 17 is provided on the bottom plate 1. A fixing pin 51 is penetrated at a position corresponding to the limiting hole 17 on the connecting plate 5, and the protruding ends of the fixing pin 51 at the corresponding ends extend into the limiting hole 17, so that the two pressure plates are respectively limited and fixed on the bottom plate 1.

[0024] The right pressure plate 42 is fixedly connected to one end of the binding strap 45 , and the other end of the binding strap 45 is bonded to the left pressure plate 41 by a Velcro 46 .

[0025] The fixing plate 43 is provided with a through hole 431 for the animal's tail to pass through.

[0026] The operating principle of the utility model is as follows:

[0027] like Figures 1 to 4 As shown, at least two positioning holes 21, preferably four, are vertically provided on the fixing frame 2 from top to bottom. Similarly, eight limiting holes 17 are symmetrically provided on the bottom plate 1 at the positions corresponding to the two fixing pins 15 along the axial direction of the guide groove 16, so as to adjust the positions of the positioning plate 12 and the two pressure plates; an insertion rod 18 is provided on the positioning plate 12, and a socket is provided at the position corresponding to the insertion rod 18 on the positioning block 11, and the insertion rod 18 extends into the socket to guide the upward and downward movement of the positioning plate 12.

[0028] When in use, the animal's head is passed through the yielding groove 22 of the fixing frame 2 and placed in the placement groove 14 of the positioning block 11, and then the positioning plate 12 is moved down, and the groove wall of the limiting groove 121 is made to fit the neck position of the animal, and then, the protruding end of the positioning pin 15 is extended into the positioning hole 21 at the corresponding position to realize the limiting fixation of the positioning plate 12 on the fixing frame 2 and limit the telescopic movement of the animal's head.

[0029] Next, the left pressure plate 41 and the right pressure plate 42 are moved along the axial direction of the guide groove 16 and moved closer to each other. When the two pressure plates fit the body of the animal, the protruding ends of the fixing pins 51 at the corresponding ends extend into the limiting holes 17, so that the two pressure plates are respectively fixed on the bottom plate 1 to limit the movement of the animal's body and the twisting of the animal's head.

[0030] At the same time, the animal's tail needs to be passed through the through hole 431 on the fixing plate 43 to prevent the animal from swinging its tail and affecting the blood collection operation.

[0031] After the animal is positioned, according to the previously found blood vessel acupuncture position, the pressure plate 13 is moved down and fit against the neck of the animal, and the slider 3 is moved to the acupuncture position with one finger, and the needle tip is inserted into the guide hole 31 and the acupuncture position is acupunctured. After the acupuncture, the needle tip is removed, and the pressure plate 13 is released. The pressure plate 13 is moved upward under the elastic force of the tension spring 23. At this time, blood is squeezed out at the acupuncture site and blood is collected with blood collection paper or a blood collection bottle. Finally, the acupuncture site is disinfected to stop bleeding.

[0032] It should be noted that, in order to facilitate the movement of the slider 3, the upper end surface of the slider 3 is arc-shaped and flush with the upper end surface of the pressure plate 13. At the same time, in order to avoid puncturing the animal's blood vessels, the thickness of the pressure plate 13 should be 2 to 4 mm less than the length of the needle tip, that is, when the needle tip seat abuts the slider 3, the length of the needle tip exposed from the lower end surface of the pressure plate 13 is in the range of 2 to 4 mm, preferably 3 mm.

[0033] In addition, if blood sampling from the neck vein is required, the pressing plate 13 does not need to be moved. Under the premise that the head and body of the animal are limited, it is more conducive to finding the blood vessels. Once the blood vessels are found, blood can be directly collected by conventional needle puncture.

[0034] Finally, when it is necessary to draw blood from the heart or the feet of the animal, a strap 45 is bonded to the left pressure plate 41 by Velcro 46. The two pressure plates can better limit the movement of the animal's limbs and facilitate the adjustment and selection of the blood collection position. The number of straps 45 should be appropriate to facilitate fixing the animal without affecting blood collection, and will not be repeated here.
