[0023] Embodiment: Auxiliary device for injecting into the marginal vein of a rabbit ear

[0024] As Figures 1-6 shown, the auxiliary device for injecting into the marginal vein of a rabbit ear, its specific structure includes:

[0025] A holding plate 10, a limiting component 20, a holding clamp 30, and an LED lighting lamp 40. The upper and lower parts of the front surface of the holding plate 10 are respectively movably installed with the holding clamp 30 through the corresponding limiting components 20. The middle part of one side of the front surface of the holding plate 10 is fixedly installed with an LED lighting lamp 40. A movable blood vessel clamp 50 is provided on one side of the front surface of the holding plate 10. The slidable blood vessel clamp 50 is used for clamping the distended blood vessel and fixing the scalp needle tip. The blood vessel clamp 50 and the LED lighting lamp 40 are located on the same side of the holding plate 10;

[0026] Among them, the limiting component 20 includes:

[0027] Positioning studs 201. Positioning holes 202 are respectively opened at the four corners of the front surface of the holding plate 10. The positioning studs 201 are respectively slidably and fittingly installed in the positioning holes 202. The positioning studs 201 are respectively connected to the positioning holes 202 through corresponding elastic members;

[0028] Adjusting nuts 203. Through holes 301 are respectively opened on both sides of the front surface of the holding clamp 30. The positioning studs 201 respectively pass through the corresponding through holes 301, and adjusting nuts 203 are threadedly fitted on the positioning studs 201. The adjusting screw holes 203 cooperate with the holding plate 10 to realize the clamping and limiting of the holding clamp 30.

[0029] When this device is in use, the positioning stud 201 and the adjusting nut 203 in the limiting component cooperate with each other to install and limit the two Baoding splints 30 located above and below the Baoding support plate 10. When in use, pull the Baoding splint 30 forward to increase the gap between the Baoding splint 30 and the Baoding support plate 10, then the rabbit ear can be inserted between the Baoding splint 30 and the Baoding support plate 10. After flattening the rabbit ear, release the Baoding splint 30. At this time, the positioning stud 201 moves and resets into the positioning hole 202 under the action of the elastic force of the elastic member, and the adjusting nut 203 plays a corresponding limiting role on the Baoding splint 30, preventing the Baoding splint 30 from detaching from the positioning stud 201. When the rabbit ear is clamped, the positioning stud 201 exerts a corresponding pressure on the Baoding splint 30 through the adjusting nut 203, so that the Baoding splint 30 and the Baoding support plate 10 cooperate with each other to clamp and fix the rabbit ear. At this time, by rotating the adjusting nut 203, it can axially move along the positioning stud 201, thereby realizing the adjustment of the pressure exerted by the adjusting nut 203 on the Baoding splint 30, and further realizing the adjustment of the clamping force of the Baoding splint 30, which is convenient for the user to use and enables this device to be suitable for the fixation of rabbit ears of different body types.

[0030] After fixing the rabbit ear, the slidable vascular clip 50 can be moved to a position 2 - 3 cm below the injection position, so that the vascular clip 50 clamps the blood vessel to make the blood vessel full. Turn on the LED lighting lamp 40 to illuminate the rabbit ear to make the rabbit ear vein clearer. After observing that the vein is full, inject the rabbit ear vein. When injecting, slowly withdraw the syringe plunger. After observing blood return, open the vascular clip 50 and slide it up to the needle to fix the needle to make the blood vessel unobstructed, and slowly inject the drug to be injected. After the injection is completed, turn off the LED lighting lamp 40.

[0031] A battery compartment 101 is provided at the rear of the Baoding support plate 10. A battery is provided in the battery compartment 101, and the battery is used to supply power to the LED lighting lamp 40. A battery compartment cover plate 102 is clamped at the opening of the battery compartment 101. A power switch 103 electrically connected to the LED lighting lamp 40 is provided on one side of the top surface of the Baoding support plate 10. In this structural design, when in use, the battery in the battery compartment 101 supplies power to the LED lighting lamp 40. When replacing the battery, only need to open the battery compartment cover plate 102 to perform the operation. The structure is simple, easy to use and convenient for the user to carry.

[0032] A tension spring 204 is fixedly installed in each of the positioning holes 202, and the front ends of the tension springs 204 are fixedly connected to the rear ends of the corresponding positioning studs 201 respectively. In the use of this structural design, the positioning studs 201 are limited by the tension springs 204. When the holding clamp 30 is pulled outwards, the holding clamp 30 can drive the positioning stud 201 to move out of the positioning hole 202 under the obstruction of the adjusting nut 203. At this time, the tension spring 204 is stretched. When the holding clamp 30 is released, the positioning stud 201 can be pulled to move back under the action of the pulling force of the tension spring 204, and the pulling force of the tension spring 204 can be converted into the pressure of the adjusting nut 203 on the holding clamp 30 during the process of clamping the rabbit ear, ensuring the clamping effect of the device on the rabbit ear.

[0033] A chute 501 is provided on one side of the holding plate 10 close to the LED lighting lamp 40. A slider 502 is slidably installed in the chute 501. A connecting plate 503 is fixedly installed at the front part of the slider 502. One end of the hemostat 50 is fixedly connected to one side of the connecting plate 503, and the hemostat 50 can move to the front of the LED lighting lamp 40. In the use of this device, the mutual cooperation between the chute 501 and the slider 502 can facilitate the movement of the hemostat 50. The cross sections of the chute 501 and the slider 502 are both T-shaped structures, which can improve the stability of the slider 502 during movement.

[0034] A concave portion 302 protruding upwards is provided on one side of the bottom of the holding clamp 30. When the holding clamp 30 clamps the rabbit ear, the concave portion 302 is located above the vein and does not compress the marginal ear vein. This structural design can leave a corresponding gap between the holding clamp 30 and the rabbit ear during use. After ensuring that the rabbit ear is clamped and fixed, it can also avoid the holding clamp 30 compressing the marginal ear vein and ensure the normal circulation of the rabbit marginal ear vein.

[0035] A buffer pad 303 made of frosted silicone is fixedly installed on the bottom surface of the holding clamp 30. The buffer pad 303 made of frosted silicone can improve the comfort when the holding clamp 30 clamps the rabbit ear, making the device neither damage the skin and blood vessels nor easily slip off after clamping the rabbit ear, and improving the reliability of the device.
