Description

Technical Field

[0001] This utility model belongs to the field of experimental equipment technology, specifically relating to a mouse tail blood collection and restraint device. Background Technology

[0002] In medical research, mice, due to their high similarity to human gene sequences, have become indispensable experimental model animals. Blood collection from mice is a common and crucial procedure in experiments. Currently, the common practice is for one researcher to hold the mouse still while another uses a syringe to collect blood from its tail. This process, involving prolonged manual restraint and precise blood collection, significantly increases the physical exertion of the researchers, easily leading to fatigue and affecting work efficiency and accuracy. Furthermore, mice may struggle due to fear or pain during blood collection, posing a risk of accidental injury to the researchers. In addition, mouse blood vessels are small and difficult to observe, especially in low light conditions, making it difficult for researchers to accurately locate the blood collection point, potentially leading to failed blood collection or inaccurate experimental results.

[0003] Therefore, it is particularly important to develop a convenient, safe, and stable device for collecting and restraining mouse tail blood. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a mouse tail blood collection and restraint device, which effectively solves the problems of insufficient safety and poor stability in the current mouse tail blood collection process.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] A mouse tail blood collection and restraint device includes a base. A mouse restraint assembly is fixedly mounted on the upper surface of the base by bolts. The mouse restraint assembly includes a cylindrical fixing cylinder for accommodating the mouse body and a semi-cylindrical placement platform for placing the mouse tail. The left end face of the placement platform is seamlessly connected to the lower half of the right end face of the fixing cylinder, and the left end of the fixing cylinder is open. A first rectangular channel is formed horizontally at the top of the fixing cylinder, and a second rectangular channel is formed along its axis on the upper half of the right end face of the fixing cylinder. The first rectangular channel and the second rectangular channel form a right-angled channel. A groove is provided on the upper surface of the placement platform, and the groove communicates with the bottom of the second rectangular channel.

[0007] Furthermore, LED lights are also fixedly installed on the upper surface of the placement platform, and the LED lights are symmetrically arranged on both sides of the groove.

[0008] Furthermore, both the first rectangular channel and the second rectangular channel penetrate the wall thickness of the fixed cylinder and are fully connected to the internal space of the fixed cylinder.

[0009] Furthermore, the restraining device also includes an adjustment component, which includes a conical plug whose size is adapted to the inner cavity of the fixed cylinder and can slide along the inner wall of the fixed cylinder.

[0010] Furthermore, a vent hole is provided at the top of the conical plug.

[0011] Furthermore, a connecting rod is installed on the bottom periphery of the conical plug, and a rotating fixing button is installed on the connecting rod; the outer surface of the connecting rod is provided with external threads, and the rotating fixing button is provided with matching internal threads.

[0012] Furthermore, the connecting rod is sized to fit the first rectangular channel and can move left and right along the first rectangular channel.

[0013] Furthermore, the upper surface of the base is designed as an inclined surface, and the angle between it and the bottom surface of the base is 20°.

[0014] Furthermore, the mouse fixation component is arranged according to the direction of the inclined surface of the base, and its inclination angle matches the angle of the inclined surface of the base; and the fixing cylinder is located on the high side of the inclined surface.

[0015] Furthermore, an anti-slip pad is installed on the bottom of the base.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This invention achieves high efficiency, accuracy, and stability in the mouse tail blood collection process through the synergistic effect of the fixed cylinder, placement platform, adjustment components, first rectangular channel, and second rectangular channel. Specifically, it is manifested in the following ways:

[0018] (1) By adjusting the fit between the component (conical plug) and the first rectangular channel, the position of the conical plug can be precisely adjusted and locked by rotating the fixing knob, so that the mouse body can be fixed in the fixing cylinder relatively stably, ensuring that the mouse is relatively stable throughout the blood collection process.

[0019] (2) The first and second rectangular channels penetrate the wall thickness of the fixed cylinder in the horizontal and vertical directions, respectively, forming a right-angled channel system. This system not only connects the mouse to the internal space of the fixed cylinder but also facilitates the entry of the mouse into the fixed cylinder and the placement of the mouse's tail. The second rectangular channel connects to the groove on the placement platform, allowing the mouse's tail to be precisely positioned within the groove under the collector's pulling force. Furthermore, the symmetrically arranged LED lights on the placement platform clearly display the location of blood vessels, thereby significantly improving the accuracy and success rate of blood collection.

[0020] (3) The upper surface of the base is designed as an inclined surface with an angle of 20° with the bottom surface of the base. The mouse fixation components are set according to the direction of the inclined surface of the base. This makes it easier for the blood sample to flow smoothly into the collection bottle along the inclined direction during the collection of mouse tail blood, thus improving experimental efficiency and accuracy.

[0021] In summary, this invention improves the operational efficiency, blood collection accuracy, and overall stability of mouse tail blood collection through the synergistic effect of the fixed cylinder, placement platform, adjustment components, first rectangular channel, and second rectangular channel, providing more efficient and reliable technical support for mouse tail blood collection in medical research.

[0030] This invention provides a mouse tail blood collection and restraint device. The technical solution of this invention will be further described below with reference to the accompanying drawings:

[0031] See Figure 1 and Figure 2 As can be seen, the mouse tail blood collection and restraint device provided by this utility model includes a base 4. A mouse restraint assembly is fixedly installed on the upper surface of the base 4 by bolts. The mouse restraint assembly includes a cylindrical fixing cylinder 1 for accommodating the mouse body and a semi-cylindrical placement platform 2 for placing the mouse tail. The left end face of the placement platform 2 is seamlessly connected to the lower half of the right end face of the fixing cylinder 1. The left end of the fixing cylinder 1 is designed to be open. A first rectangular channel 11 is opened in the horizontal direction at the top of the fixing cylinder 1. A second rectangular channel 12 is opened in the axial direction on the upper half of the right end face of the fixing cylinder 1. The first rectangular channel 11 and the second rectangular channel 12 are connected to form a right-angle channel. The first rectangular channel 11 and the second rectangular channel 12 both penetrate the wall thickness of the fixing cylinder 1 and are completely connected to the internal space of the fixing cylinder 1. A groove 21 is provided on the upper surface of the placement platform 2 for placing the mouse tail, and the groove 21 is connected to the bottom of the second rectangular channel 12. An anti-slip pad 5 is installed on the bottom of the base 4.

[0032] It is worth noting that the cylindrical fixing cylinder 1 is used to accommodate the mouse's body, ensuring that the mouse remains still during the operation. The left end of the fixing cylinder 1 is designed to be open, and a first rectangular channel 11 is formed horizontally at the top of the fixing cylinder 1. This allows the operator to hold the mouse's tail and smoothly pull the mouse into the fixing cylinder 1 from the left end until the mouse's tail contacts the inner wall of the right end face of the fixing cylinder 1. At the same time, the placement platform 2 is located on the right side of the fixing cylinder 1, and its left end face is tightly fitted and seamlessly connected to the lower half of the right end face of the fixing cylinder 1 to form an integrated structure. Furthermore, a second rectangular channel 12 is formed along the axial direction on the upper half of the right end face of the fixing cylinder 1. This channel 12 communicates with the groove 21 on the placement platform 2. This design ensures that the mouse's tail inside the fixing cylinder 1 can naturally extend into the groove 21 on the placement platform 2 through the second rectangular channel 12, thereby achieving stable support and positioning of the mouse's tail and providing convenient conditions for tail blood collection and other operations.

[0033] In the above embodiment, an LED lamp 22 is also fixedly installed on the upper surface of the placement platform 2, and the LED lamp 22 is symmetrically arranged on both sides of the groove 21.

[0034] It is worth noting that the light from LED light 22 can enhance the visibility of blood vessels in the mouse's tail, making the vessels more prominent and facilitating accurate blood collection by the operator. Furthermore, the symmetrically arranged LED lights on both sides of the groove 21 can evenly illuminate the tail area, reducing shadow interference and further improving operational accuracy; these are touch-sensitive, rechargeable LED lights.

[0035] See Figure 1 and Figure 3 As can be seen, in the above embodiments, the restraining device further includes an adjustment component 3, which includes a conical plug 31. The size of the conical plug 31 is adapted to the inner cavity of the fixed cylinder 1, and it can slide along the inner wall of the fixed cylinder 1. Furthermore, a vent hole 32 is provided at the top of the conical plug 31, and a connecting rod 33 is fixedly installed on the bottom periphery of the conical plug 31. A rotating fixing knob 34 is installed on the connecting rod 33. The outer surface of the connecting rod 33 is provided with an external thread, and the rotating fixing knob 34 is provided with a matching internal thread. The size of the connecting rod 33 is adapted to the first rectangular channel 11, and it can move left and right along the first rectangular channel 11.

[0036] It is worth noting that the size of the conical plug 31 is adapted to the inner cavity of the fixing cylinder 1, allowing it to slide along the inner wall of the fixing cylinder 1. This design enables the conical plug 31 to be adjusted in position as needed, ensuring that the mouse body is firmly fixed inside the fixing cylinder 1. Furthermore, by pushing or pulling the connecting rod 33, the position of the conical plug 31 inside the fixing cylinder 1 can be precisely adjusted, thereby controlling the position of the mouse inside the fixing cylinder 1. The adaptation design of the connecting rod 33 and the first rectangular channel 11 ensures that the sliding direction of the conical plug 31 is always along the axial direction of the fixing cylinder 1. When the mouse's position is adjusted to a suitable state, the conical plug 31 can be locked in its current position by rotating the fixing knob 34 on the connecting rod 33, ensuring that the mouse remains stable throughout the tail blood collection process. At the same time, a vent 32 is provided at the top of the conical plug 31, allowing air to circulate inside the fixing cylinder 1 and preventing the mouse from feeling uncomfortable or hypoxic due to prolonged restraint.

[0037] In the above embodiment, the upper surface of the base 4 is designed as an inclined surface, and the angle between the upper surface of the base 4 and the bottom surface of the base 4 is 20°. The mouse fixation component is arranged according to the direction of the inclined surface of the base 4, and its inclination angle matches the angle of the inclined surface of the base 4; and the fixing cylinder 1 is located on the high side of the inclined surface.

[0038] It is worth noting that in the mouse tail blood collection and restraint device, the fixed cylinder 1 is positioned at the high point of the inclined surface of the base 4, which facilitates the smooth flow of blood samples into the collection bottle along the inclined direction, thereby improving experimental efficiency and accuracy.

[0039] In the above embodiment, an anti-slip pad 5 is installed on the bottom of the base 4. The anti-slip pad 5 is designed to enhance the friction between the device and the supporting surface, preventing the device from sliding during use.

[0040] The working principle of this utility model is as follows: During use, place the device on a stable workbench, ensuring the anti-slip pad 5 at the bottom of the base 4 is in full contact with the workbench surface to enhance stability. The adjustment component 3 is not inserted into the fixed cylinder 1, and the LED light 22 is off. The operator brings the mouse's tail close to the opening at the left end of the fixed cylinder 1, gently lifts and pinches the mouse's tail, passes it through the first rectangular channel 11, and pulls the mouse's tail to the right, gradually moving the mouse's body into the fixed cylinder 1 until the mouse's tail contacts the inner wall of the right end of the fixed cylinder 1. Then, place the mouse's tail through the second rectangular channel 12 into the groove 21 on the placement platform 2, ensuring the tail is straight and stably placed in the groove 21 under the operator's pulling force. Insert the adjustment component 3 from the left end of the fixed cylinder 1 and push the conical plug 31 to the right along the inner wall of the fixed cylinder 1. Adjust the position of the conical plug 31 according to the mouse's position inside the fixed cylinder 1, ensuring it contacts the mouse's head to securely fix the mouse. Once the position is determined, the conical plug 31 is locked in place by rotating the rotating fixing knob 34 on the connecting rod 33, thus ensuring the mouse remains stable throughout the tail blood collection process. The symmetrically arranged LED lights 22 on the placement platform 2 are turned on to provide sufficient illumination to the tail area, making the blood vessels in the mouse's tail more clearly visible. The operator can then accurately locate the blood collection point based on the blood vessel distribution and collect the tail blood. After blood collection, the rotating fixing knob 34 is released, the adjustment component 3 is removed from the fixing cylinder 1, the mouse is removed from the fixing cylinder 1, and properly placed.

[0041] The above provides a detailed description of a mouse tail blood collection and restraint device provided by this utility model. The above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
