Description

Technical Field

[0001] This utility model relates to the field of medical experimental technology, and in particular to an intravenous injection imaging device. Background Technology

[0002] In the field of medical research, mice are often used as important experimental animal models for studying various diseases, developing drugs, and exploring physiological and pathological mechanisms. Among these methods, intravenous injection into mice is a common and crucial experimental technique.

[0003] Traditional intravenous injection methods in mice typically rely on direct visual observation or simple lighting tools. However, mouse veins are quite small, especially in certain locations such as the gastric vein, where the diameter can be only tens to hundreds of micrometers. Under normal lighting conditions, the contrast between the veins and surrounding tissues is low, making it difficult to clearly distinguish the location and direction of the veins. Even in imaging devices with lights at the bottom, the imaging of veins is still not clear enough due to interference from external light and the limitations of the instrument's own lighting effect. This poses a significant challenge to operators in locating veins, increasing the failure rate of injections and operation time. This patent aims to provide an intravenous injection imaging device to alleviate the technical problems of existing technologies, such as difficulty in intravenous injection in low light conditions and difficulty in finding veins in strong light conditions. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as difficulty in intravenous injection in low light conditions and difficulty in finding veins in strong light conditions, and to propose an intravenous injection imaging device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An intravenous injection imaging device includes an imaging device base, a motor mounted on top of the imaging device base, a malleable metal tube fixedly connected to one side of the motor, a light shield fixedly connected to one side of the malleable metal tube, a thick glass plate mounted on top of the light shield with holes in its surface, a mouse fixation sleeve mounted on the side of the imaging device base near the motor, an adjusting baffle mounted inside the mouse fixation sleeve, a rotating latch rotatably connected above the adjusting baffle, a sleeve fixing block mounted on the side of the rotating latch near the mouse fixation sleeve, a tail-pressing rod rotatably connected to the side of the motor, a sliding mechanism mounted below the tail-pressing rod near the side of the imaging device base for adjusting the mouse tail, and a movable high-definition magnifying glass mounted on one side of the imaging device base.

[0007] The above technical solution further includes:

[0008] The sliding mechanism includes a support block disposed above the display base, a sliding plate disposed on the side of the support block, a rack disposed below the sliding plate, a gear meshing with the rack, the gear being rotatably connected to the support block, the other side of the gear being fixedly connected to a rotating column, and a stable light-emitting block being fixedly connected to the side of the sliding plate.

[0009] A light intensity adjuster is provided on one side of the display base for adjusting the light intensity of the stable light-emitting block.

[0010] One end of the mouse fixation sleeve is equipped with a tail clamp to prevent the mouse from moving, and one end of the mouse fixation sleeve can be locked into the slot reserved in the sleeve fixing block.

[0011] A semi-circular hole for placing the mouse's tail is provided below the tail-pressing rod.

[0012] Above the base of the display unit is a power indicator light to show whether the power supply is operating normally, and to one side of the power indicator light is a pressure rod speed adjuster for adjusting the descent speed of the pressure rod.

[0013] Above the base of the imaging device is a light source switch for adjusting the activation of the stable light-emitting block. On one side of the light source switch is a pressure rod lifter for adjusting the raising of the pressure rod, and on one side of the pressure rod lifter is a pressure rod lowerer for adjusting the lowering of the pressure rod.

[0014] A fixed ruler is provided above the sliding plate to support the mouse's tail.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the problem of inconvenient intravenous injection in dim light and difficulty in finding blood vessels in bright light is addressed by the innovative design of this intravenous injection imaging device. The application of its light shield effectively blocks excessive external light interference, creating a relatively stable and suitable observation environment. When the operator performs intravenous injection on mice, there is no need to worry about the influence of external light on blood vessel observation. Even in a laboratory environment with complex lighting, the operator can focus on imaging the blood vessels in the tail of the mouse and can observe them using a high-definition display mirror even in bright light conditions.

[0017] 2. In this invention, the stable light-emitting block inside the instrument provides a controllable light source. Through the light intensity regulator, the operator can adjust the light intensity to the most suitable state for observing blood vessels according to the actual situation. Whether in a dimly lit indoor corner or in a bright laboratory environment during the day, blood vessels can be clearly seen. This precise control over light greatly improves the accuracy and success rate of intravenous injection operations, effectively solving the problems caused by light issues in traditional techniques.

[0025] In one embodiment, the sliding mechanism includes a support block 17 disposed above the display base 1, a sliding plate 18 disposed on the side of the support block 17, a rack 22 disposed below the sliding plate 18, a gear 21 meshing with the rack 22, the gear 21 being rotatably connected to the support block 17, the other side of the gear 21 being fixedly connected to the rotating column 19, and a stable light-emitting block 20 being fixedly connected to the side of the sliding plate 18.

[0026] In this embodiment, the sliding mechanism can effectively support the tails of different mice before injection, ensuring convenience during intravenous injection.

[0027] In one embodiment, for the display base 1, a light intensity adjuster 7 for adjusting the light intensity of the stable light-emitting block 20 is provided on one side of the display base 1.

[0028] In one embodiment, for the mouse fixation sleeve 13, one end of the mouse fixation sleeve 13 is provided with a tail clamp baffle to prevent the mouse from moving, and one end of the mouse fixation sleeve 13 can be just locked in the slot reserved in the sleeve fixing block 16.

[0029] In this embodiment, the mouse fixation cannula 13 is used to fix the body size of different mice, preventing the mice from moving around and causing their tails to wag during intravenous injection, which could lead to possible intravenous injection failure.

[0030] In one embodiment, the tail-pressing rod 12 has a semi-circular hole below it for placing the mouse's tail.

[0031] In this embodiment, by setting the tail-pressing rod 12, the tail of the mouse can be locked inside the semi-circular hole, which further ensures the stability of operation under intravenous injection.

[0032] In one embodiment, for the display base 1, a power indicator light 2 is provided above the display base 1 to indicate whether the power supply is operating normally, and a pressure rod speed adjuster 3 is provided on one side of the power indicator light 2 to adjust the descent speed of the pressure rod 12.

[0033] In this embodiment, the power indicator light 2 located above the display base 1 allows for easy observation of whether the machine is operating normally, and the pressure rod speed adjuster, which adjusts the descent speed of the pressure rod 12, enables adaptability to different situations.

[0034] In one embodiment, for the display base 1, a light source switch 4 for adjusting the light activation of the stable light-emitting block 20 is provided above the display base 1.

A pressure rod lowering device 6 for adjusting the lowering of the tail rod 12 is provided on one side of the pressure rod lifter 5. A fixed ruler for supporting the tail of the mouse is provided above the sliding plate 18.

[0035] In this embodiment, the light intensity of the adjustable and stable light-emitting block 20, which is set above the imaging device base 1, is used to facilitate the location of veins during subsequent intravenous injection. The mouse can be fixed by using the rising and falling tail lever, and the operation can be completed by pressing the switch lever during the falling phase 6.

[0036] The working principle of the intravenous injection imaging device of this utility model is as follows: First, the operator presses the lever lifter 5 to raise the tail-pressing lever 12, then takes out the mouse fixation cannula 13 that is stuck above the cannula fixing block 16, then takes out the adjusting baffle 14, and then puts the mouse into the mouse fixation cannula 13. Then, the adjusting baffle 14 passes through one end of the mouse fixation cannula 13 to block the mouse. Since one end of the mouse fixation cannula 13 is provided with an opening that can just allow the mouse tail to pass through, after the mouse tail extends out from one end of the mouse fixation cannula 13, the adjusting baffle 14 above the rotating clip 15 is used to fix it inside the mouse fixation cannula 13 that is adapted to the mouse body shape. Then, the mouse tail is straightened, and then the mouse tail is stuck in the reserved slot above the imaging device base 1. Then, the lever lowerer 6 is pressed, and the tail-pressing lever 12 will press down the mouse tail. Then, according to the appropriate tail of the mouse, the pre-intravenous injection measures are performed.

[0037] First, apply a disinfectant liquid to the mouse's tail to dilate its blood vessels. Then, rotate the rotating column 19, which in turn drives the gear 21 to rotate. The rack 22 then drives the sliding plate 18 to slide. Compare the mouse length with the ruler next to it. Once the desired mouse length is reached, activate the light intensity regulator 7. The stable light-emitting block 20 will then emit light. Continue rotating the light intensity regulator 7, and the light intensity of the stable light-emitting block 20 will continuously increase. After adjusting to the appropriate brightness, drag the light shield 23. The malleable metal tube 8 on its side will be malleable. Drag it to the upper part of the mouse's tail and cover it with the light shield 23. Above the light shield 23, there is a thick glass 9 that can reduce the light intensity. The staff can then observe the mouse's tail through the hole 10. On the other side of the hole 10, there is an operable opening, which allows for intravenous injection of the mouse without turning off the lights. When the light shield is not needed, observation can be performed using a high-definition magnifying glass 24.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
