Description

Technical Field

[0001] The utility model relates to the technical field of mouse experimental devices, in particular to a tool component used for mouse tracheal intubation experiments. Background Art

[0002] Animal experiments, also known as experimental animal science, have now become an integral part of modern science and technology and have formed an independent comprehensive basic science category. The importance of this science lies in that, on the one hand, as an important means of scientific research, it directly affects the establishment and level of research results in many fields; on the other hand, as a science, its improvement and development will bring the research of many fields into a new realm.

[0003] Tracheal intubation of animals is a relatively common animal experimental operation. It can be used to administer drugs into the animal's airway to observe the effects of various drugs on the animal's lungs, to clarify the pathological mechanism of lung diseases and try possible treatment options, to provide an animal experimental basis for the treatment of human diseases, and to facilitate the subsequent human clinical drug experiments.

[0004] During the mouse tracheal intubation experiment, a light source is needed to illuminate the inside of the mouse's mouth, which is convenient for animal experimenters to view. The tongue of the mouse must be pressed down by a tongue depressor to fully expose the mouse's glottis structure. At the same time, the tongue depressor needs to meet the personnel's operation direction requirements. In the existing tracheal intubation light-emitting devices, the light source is either a single handheld spotlight or an external desk lamp and is directional lighting through a gooseneck tube. The common disadvantage is that the lighting position is high and located outside the mouth, and the light may be offset. The mouse mouth is small and pointed, and the glottis is deep. The external lighting light is difficult to effectively illuminate the glottis, and the offset light will affect the operation field of view, all of which are not conducive to the smooth operation. The existing luminous tongue depressor has a fixed light source and a high light source position, which cannot accurately locate the mouse glottis position, and cannot meet the tracheal intubation requirements of mice of different growth cycles and weights; the mouse's mouth is narrow, the tongue is small and slippery, and a general small stick is used as a tongue depressor, which is difficult to press the mouse tongue into place, and fixing the mouse tongue is an important step in tracheal intubation. The current tongue depressor for endotracheal intubation laryngoscope is relatively large and has sharp edges, which is not conducive to protecting the oral structure of mice. In addition, the current luminous tongue depressor is generally linear, which is not conducive to the direction of experimental operation.

[0005] Based on this, the utility model designs a tool assembly for mouse tracheal intubation experiment to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a tool assembly for mouse tracheal intubation experiments. The device adds a directional light source to the tongue depressor, which only illuminates the inside of the mouse's oral cavity and can extend the light to the glottis of the mouse's larynx. The tongue depressor is improved to be able to adjust the insertion depth and brightness, and the size is also adapted to the size of the mouse's oral cavity. The curved design of the front end of the tongue depressor can conveniently pull the mouse's oral cavity forward with a small force, and ensure that the upper space is large enough, which is conducive to the subsequent tracheal intubation operation. One hand completes the lighting and tongue depressing at the same time, and can also assist the intubation operation structure, which provides convenience for the mouse tracheal intubation experiment. At the same time, the mouse positioning bracket of the device can bind the mouse stably, and can also support and adjust the front and rear multi-angles, and can be adaptively adjusted according to the required angles, so that animal experimenters of different heights and sitting heights can reasonably adjust the angle to accurately locate and fully expose the mouse's glottis, which is conducive to the subsequent tracheal intubation. In addition, the front side of the bracket is provided with an arc support plate that can support the forward tilt, which can make the entire bracket tilt forward, and it is also convenient for animal experimenters to adjust the angle to view the glottis.

[0007] The utility model is implemented as follows: a tool assembly for mouse tracheal intubation experiment, comprising:

[0008] Includes stand and tongue depressor;

[0009] The tongue depressor comprises a tongue depressor rod, a lighting lamp and a connecting curved rod;

[0013] A front rocker is provided at the front end of the bottom plate, and the front rocker is a flat plate with the front end raised upwards;

[0014] A support plate is also provided on the front side of the vertical plate, and the support plate can be stably adsorbed on the front side of the vertical plate by adjusting the position through a magnet. A limiting sleeve hole is also provided on the support plate, and the limiting sleeve hole penetrates the upper and lower surfaces of the support plate;

[0015] The bottom bracket is an inverted trapezoidal structure that is thin at the front and rear ends and thick in the middle. The left and right sides of the bottom plate are both stably adsorbed with a bottom bracket that can be separated by magnets.

[0016] The beneficial effects of the utility model are as follows: 1. The tongue depressor of the device is integrated with a directional spotlight, so that the tongue depressor itself can illuminate the inside of the oral cavity, and tongue depressing and lighting can be performed simultaneously, which can be completed with one hand, and the operation will be more convenient; the front end of the tongue depressor can also adjust the telescopic length to adapt to the different mouth lengths and depths of mice in different growth cycles, thereby ensuring that the device can perform lighting and tongue depressing operations in the oral cavity of mice in different growth cycles, thereby expanding the scope of application of the device;

[0017] 2. This device uses directional spotlights and adds irradiation in the direction of the trachea, so that the light only illuminates the mouse glottis without irritating the operator's sight. It is more convenient to operate, and can be inserted into the oral cavity to directly illuminate the operating area, making the lighting positioning more accurate;

[0018] 3. The bracket of this device can support at multiple angles, and can also be tilted and rotated forward after the support is stable.

DETAILED DESCRIPTION

[0031] See also Figures 1 to 8 As shown, the utility model provides a tool assembly for mouse tracheal intubation experiments. In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings in the specification and specific implementation methods.

[0032] In a specific embodiment of the technical solution of the utility model:

[0033] Includes stand and tongue depressor;

[0034] The tongue depressor comprises a tongue depressor rod 1, an illuminating lamp 11 and a connecting curved rod 13;

[0035] The tongue depressor 1 is a straight rod, and the front end of the tongue depressor 1 is a connecting curved rod 13, and a lighting lamp 11 is arranged at the front end of the connecting curved rod 13. The lighting lamp 11 is stably inserted at the front end of the connecting curved rod 13, and a telescopic rod 12 is installed at the front end of the lighting lamp 11. The lighting lamp 11, the telescopic rod 12 and the tongue depressor 1 are assembled and locked into an L-shaped long rod through the connecting curved rod 13. A pressing plate 121 is arranged at the front end of the telescopic rod 12, and the pressing plate 121 is a quasi-circular flat plate, and the front end of the pressing plate 121 is tilted upward;

[0036] The lighting lamp 11 is a hollow cylindrical lamp tube, and the lighting lamp 11 and the sunshade 111 are covered to form an integral circular tube structure, and a wick 112 is arranged in the cavity of the sunshade 111 and the lighting lamp 11; the lighting lamp 11 and the sunshade 111 are embedded to form an integral circular tube, and the wick 112 is enclosed in the circular tube formed by the lighting lamp 11 and the sunshade 111 to ensure sealing.

[0037] The telescopic rod 12 is slidably mounted on the outside of the illuminating lamp 11; a plurality of snap-in convex points 113 are arranged on the outside of the illuminating lamp 11, and a circular groove is arranged on the inner wall of the telescopic rod 12. The snap-in convex points 113 and the groove on the inner wall of the telescopic rod 12 can be detachably snapped into each other. Such snap-in convex points 113 protrude outward from the outer wall of the circular tube of the illuminating lamp 11. When the snap-in convex points 11 abut against the smooth inner wall of the telescopic rod 12, they are interference fit. When the snap-in convex points 11 and the groove position of the telescopic rod 12 correspond, the snap-in convex points 11 snap into the groove of the telescopic rod 12. The groove on the inner wall of the telescopic rod 12 needs to be arranged at a plurality of different telescopic positions to match the snap-in of the snap-in convex points 11. Such a combination of a snap-in convex point 11 with a multi-point groove belongs to the conventional setting of the snap-in position of the telescopic rod. The present device only needs to lock the illuminating lamp 11 and the telescopic rod 12 at different positions.

[0038] The telescopic rod 12 is a round tube made of a light-guiding material, which is convenient for guiding light in the mouse oral cavity and illuminating the glottis, so that personnel can view it. The telescopic rod 12 guides the light source so that the light source irradiates the mouse's laryngeal glottis without irradiating the eyes of the experimenter.

[0039] The telescopic rod 12 can be a new type of telescopic rod, or a telescopic rod with a locking pin that can be slid out. Its structure can be made by taking the structure of a mop telescopic rod used in daily life, as long as it can be locked and positioned at different telescopic positions and can be extended and retracted. By adjusting the length, it can be suitable for mice in different growth cycles. When the telescopic rod 12 needs to be extended or retracted, the telescopic rod 12 is extended to ensure that the locking protrusion 113 is locked with the protrusions on the outside of the lighting lamp 11 and the sunshade 111 to ensure stable locking.

[0040] The lamp core 112 is an LED cold light lamp; and the irradiation direction of the lamp core 112 is opposite to the direction of the shading plate 111, that is, Figure 5 The bottom shown in the figure, that is, the irradiation direction of the wick 112 is toward the transparent light-guiding side of the illuminating lamp 11, and the sight of personnel is blocked by the shading plate 111. The telescopic rod 12 has light-guiding properties and can be extended and retracted. It can be extended downward and to the front and back sides. The pressure plate 121 at the end can be hooked and extended. While pressing the tongue, light is guided deep into the mouse's throat to fully expose the glottis.

[0041] A switch 14 is provided at the rear end of the tongue depressor 1, and the switch 14 is electrically connected to the wick 112 of the illuminating lamp 11. A battery is also provided inside the tongue depressor 1, and the wick 112 is electrically connected to the battery through the switch 14. The tongue depressor 1 is hollow inside, which is convenient for connecting wires and does not affect the rotation of the telescopic rod 12. The connected line should not be fixedly connected to the inside of the tongue depressor 1, so that when the telescopic rod 12 is extended or retracted, the connected wires do not follow the movement.

[0042] The bracket includes a vertical plate 2, a frame plate 21, a bottom plate 3 and a bottom bracket 4. The vertical plate 2, the frame plate 21 and the bottom plate 3 are all flat plates. The bottom of the bottom plate 3 is flat. The front end of the vertical plate 2 can be turned up and installed on the front end of the bottom plate 3 through a rotating shaft. The frame plate 21 can be turned up and installed on the rear end of the bottom plate 3. The front end of the frame plate 21 can be separated and stably supported on the rear side of the vertical plate 2.

[0043] A front rocker panel 31 is provided at the front end of the base plate 3. The front rocker panel 31 is a flat plate with the front end raised upward. The angle between the front rocker panel 31 and the horizontal plane is 45°. The front rocker panel 31 is seamlessly connected to the front end of the base plate 3. Such a structure enables the base plate 3 to tilt forward, and the front rocker panel 31 is supported in contact with the operating table, so that the entire bracket is tilted and stably supported on the operating table.

[0044] A support plate 22 is also provided on the front side of the vertical plate 2. The support plate 22 can be stably adsorbed on the front side of the vertical plate 2 by adjusting its position through magnets.

[0045] A binding rope 23 is also provided at the upper end of the vertical plate 2. The binding rope 23 is arranged along the left and right directions. The binding rope 23 can be an iron wire. Two holes are opened at the upper end of the vertical plate 2 for putting on and positioning the binding rope 23. The function of the binding rope 23 is to fix the mouse's head by hanging the mouse's incisors to facilitate operation.

[0046] A ring 25 is also provided on the vertical board 2. The ring 25 is an elastic rubber ring. The ring 25 can be detachably sleeved on the vertical board 2 to facilitate binding of the mouse and restrict the body of the mouse from fitting against the vertical board 2 without damaging the mouse's hair.

[0047] The bottom bracket 4 is an inverted trapezoidal structure with thin ends at the front and rear ends and a thick middle. The left and right sides of the bottom plate 3 are both stably adsorbed with a bottom bracket 4 that can be separated by magnets.

[0048] The top and bottom planes of the bottom bracket 4 are parallel to each other, that is, the top and bottom middle planes of the bottom bracket 4 are parallel to each other. When the bottom bracket 4 is stably adsorbed on the bottom of the bottom plate 3, the bottom middle position of the bottom bracket 4 can maintain horizontal support with the bottom plate 3 instrument.

[0049] A forward slope 41 is provided at the front end of the bottom of the bottom bracket 4, and the forward slope 41 is a slope that is higher at the front and lower at the back;

[0050] A rearward slope 42 is provided at the rear end of the bottom of the base 4. The rearward slope 42 is a slope that is lower in the front and higher in the back. The forward slope 41 and the rearward slope 42 are seamlessly connected with the bottom of the base 4. The angle a of the forward slope 41 and the angle b of the rearward slope 42 do not exceed 10°, and a is greater than b. Such a base 4 allows the entire bottom plate 3 to tilt in the front and back directions. When the thrust and downward pressure are different, the forward slope 41, the rearward slope 42, the base 4 and the bottom surface of the front rocker 31 are all flat surfaces. The forward slope 41, the rearward slope 42, the bottom of the base 4 and the front rocker 31 can be supported in contact with the operating table, and each different slope can provide stable support, which is convenient for the mouse's mouth to be directed to different angles and for observing the inside of the airway at different positions.

[0051] It should be noted that:

[0052] 1. Existing brackets generally require stable support. When they are stably supported, the disadvantage is obvious. They can only be supported at a specific angle. Even if the bracket can be adjusted, it cannot be flexibly adjusted in real time during operation. The bracket can only be adjusted again. The device not only allows the bracket to adjust its support angle, but also allows the wrist or palm to be supported on the top of the bracket during operation, and the bracket can be shaken to flexibly adjust the angle. It can also be positioned at multiple angles, making the operation more convenient and flexible.

[0053] 2. The current tongue depressors are straight-bar tongue depressors, some of which have too wide front ends to be inserted into the mouse's mouth without damaging the mouse's oral structure; some straight-bar tongue depressors are designed with smaller tongue depressors that can be inserted into the root of the tongue, but the operator's hand direction will block the tracheal intubation operation, causing inconvenience, that is, the tongue depressor, light, and tracheal intubation syringe are all gathered just above the mouse's mouth, occupying the already narrow upper oral space of the mouse, affecting each other and causing inconvenience to the operation. This device uses an L-shaped design to move the handheld part of the illuminated tongue depressor forward to the front of the mouse's mouth, freeing up the upper oral operating space for the mouse, allowing the operator to easily observe the mouse's glottis and perform subsequent tracheal intubation and intratracheal injection operations.

[0054] When the utility model is in use, the vertical plate 2 and the frame plate 21 are first rotated and spread apart, so that the bottom plate 3, the vertical plate 2 and the frame plate 21 form a triangular support structure. The support relationship between the vertical plate 2 and the frame plate 21 can be that a plurality of slots 24 are opened on the back of the vertical plate 2, and the frame plate 21 is tightly inserted into the slots 24, and the frame plate 21 and the slots 24 on the back of the vertical plate 2 are transitionally matched to ensure that they are tightly inserted. This plug-in support method of the slots 24 and the flat plate is a conventional structure. As shown in the figure, the rear end of the frame plate 21 is installed on the bottom plate 3 through a rotating shaft, and the front end of the vertical plate 2 is also installed with the front end of the bottom plate 3 through a rotating shaft, and the vertical plate 2 and the frame plate 21 can also be flipped and embedded in the same plane with the bottom plate 3, such as Figure 2As shown, its shape does not need to be limited, it only needs to ensure that it can be turned over and supported to form a stable supporting structure.

[0055] According to the usage habits of people, the base bracket 4 is installed, and two long strip base brackets 4 are placed on the left and right sides of the base plate 3 along the front and rear directions, so that the forward inclined slope 41 and the rearward inclined slope 42 of the base bracket 4 are respectively arranged on the front and rear sides of the base plate 3, and the forward inclined slope 41 and the rearward inclined slope 42 on the left and right sides need to be magnetically installed in the same front and rear directions.

[0056] The vertical plate 2 of the device needs to have a downward vertical protrusion for binding the mouse. The protrusion needs to be used to magnetically attract the support plate 22. The support plate 22 is a flat plate. The support plate 22 and the vertical plate 2 are perpendicular to each other and are used to lift the feet or buttocks of the mouse so that the mouse is effectively supported.

[0057] A limiting hole 221 is also provided on the support plate 22. The limiting hole 221 penetrates the upper and lower surfaces of the support plate 22. The limiting hole 221 is a waist-shaped hole, which is convenient for the mouse's legs to be inserted into the limiting hole 221 and can prevent the mouse's buttocks and abdomen from falling, and can effectively hold the mouse on the support plate 22.

[0058] Place the back of the mouse against the front side of the vertical board 2, and then wrap the mouse around the vertical board 2 with medical tape to ensure stability. The load-bearing capacity of the entire mouse depends on the vertical support of the support plate 22. The strap does not actually bear the vertical supporting force, and the support plate 22 is adsorbed to the vertical board 2 by a strong magnet. Strong magnets are embedded at the bottom of the support plate 22 and the top of the bottom support 4, so the adsorption is stable.

[0059] Then, according to actual needs, the top of the vertical plate 2 can be pushed and pulled to a suitable angle, that is, the forward slope 41, the rearward slope 42, the bottom of the bottom support 4 and the front rocker 31 are supported in a fit with the operating platform, and the support angle of the entire bracket is different. After the entire bracket is pushed and pulled to a suitable angle, the vertical plate 2 can be pressed to keep the bracket stable. The mouse is light in weight, and the bracket can be kept stable by pressing lightly. It is precisely because of the structure of this device that the support plate 22 and the bottom support 4 both rely on magnetic attraction, and the adjustment angle also relies on hand support, so it can only be applied to mice with relatively small body size, and rabbits and other larger experimental subjects cannot be applied. However, such a structure makes the operator more flexible in operation and more convenient to use.

[0060] Then adjust the length of the telescopic rod 12 on the tongue depressor 1 to be roughly the same as the length of the oral cavity of the experimental mouse, and then turn on the switch 14 to light up the wick 112 of the illuminating lamp 11, and the illuminating lamp 11 is inserted into the oral cavity of the mouse to illuminate the airway inside the oral cavity to keep the oral cavity of the mouse bright. The shading plate 111 will block the light directed to the animal experimenter to prevent the illuminating lamp 11 from being dazzling. The telescopic rod 12 at the front end of the illuminating lamp 11 goes deep into the oral cavity to press the tongue of the mouse, and the pressing plate 121 at the front end is tilted upward. During operation, the tilting direction of the pressing plate 121 is toward the outside of the oral cavity of the mouse, so that it is convenient to stretch the tongue of the mouse for spreading and pressing, and the illuminating lamp 11 can directly illuminate the glottis of the mouse; then the tracheal intubation of the mouse can be started to complete the experiment.

[0061] The front and back of this device refers to the direction in which the experimenter sits. When binding a mouse, the mouse's belly faces forward, the mouse's back is against the vertical board 2, the mouse's head faces upward, and one side of the frame board 21 is the back side. The operator sits at the back side of the entire device and observes the mouse's oral cavity from top to bottom.

[0062] Furthermore, the orientation or positional relationship indicated is based on the orientation or positional relationship shown in the accompanying drawings and is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0063] Although the specific implementation methods of the present invention are described above, those skilled in the art should understand that the specific embodiments described are only illustrative and are not intended to limit the scope of the present invention. Equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the present invention should be included in the scope of protection of the claims of the present invention.
