Description

Technical Field

[0001] The invention relates to the technical field of preclinical auxiliary equipment for biomedicine, and in particular to a fixing device for facilitating the detection of urodynamic indicators of male dogs. Background Art

[0002] Urodynamic index testing belongs to urology, which mainly studies the physiological process of urine storage and urination and its functional disorders of animals. When performing urodynamic testing on male dogs, it is necessary to use corresponding fixing devices to safely and effectively fix the male dogs so as to collect data on urodynamic indexes such as urine flow rate, urine flow, bladder pressure at maximum urine flow rate, and detrusor pressure at maximum urine flow rate.

[0003] At present, a common corresponding fixing device is for example the Chinese patent publication number: CN214761595U, the name of which is "A restraint device for veterinary diagnosis and treatment", which includes "a bottom plate, a lifting mechanism, and a clamping mechanism. A lifting plate placed horizontally and parallel is provided above the bottom plate, and a top plate placed horizontally and parallel is provided above the lifting plate. Vertically fixed slide cylinders are provided at the four corners of the lifting plate, and vertically fixed slide rods are provided at the four corners of the top surface of the bottom plate. The top end of each slide rod slides through the corresponding slide cylinder and is fixed to the bottom corner of the top plate. The middle part of the top surface of the bottom plate is connected to the middle part of the bottom surface of the lifting plate through the lifting mechanism, and a pair of clamping mechanisms are provided on the top plate".

[0004] The existing fixing device mainly clamps or fastens the male dog's limbs with a clamp or a strap to achieve the fixing effect of the male dog. However, the above scheme has the disadvantage that when the male dog is fixed, the clamp or the strap is pressed against the same part of the limb for a long time. If the squeezing is too tight, it is easy to affect the normal physiological limit of the male dog, stimulate the male dog to be emotionally restless and move around, which is not conducive to the smooth progress of the detection work. If the squeezing is not tight, it is easy to cause the male dog to escape midway. In order to solve the above problems, we propose a fixing device that is convenient for the detection of male dog urodynamic indicators. Summary of the invention

DETAILED DESCRIPTION

[0033] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] See also Figure 1-9 The embodiment of the present invention provides a fixing device for facilitating the detection of male dog urodynamic indicators, comprising a box frame 1, a bottom plate 2 is fixed to the bottom of the box frame 1, and a clamping mechanism is provided in the frame space of the box frame 1, and the clamping mechanism comprises:

[0035] Two support assemblies 3, each of which includes a support plate 3.1 slidably installed horizontally in the box frame 1, and a slideway opening 3.2 perpendicular to the horizontal direction is opened on the support plate 3.1, and two support boxes 3.3 are slidably installed in the slideway opening 3.2;

[0036] The clamping assembly 4 comprises a through hole 4.1 provided in the middle of each supporting box 3.3, a moving frame 4.2 is slidably mounted on each through hole 4.1, a first clamping group 4.3 and a second clamping group 4.4 are distributedly mounted on the circumference of the moving frame 4.2, and the first clamping group 4.3 and the second clamping group 4.4 have a same clamping state and a single clamping state relative to each other;

[0037] The switching assembly 5 comprises a gear ring unit 5.1 which is sleeved on the clamping assembly 4, and a transmission unit 5.2 which is mounted on the supporting box 3.3 is meshed with the side of the gear ring unit 5.1. When the gear ring unit 5.1 is located on the first area surface during its rotation, the first clamping group 4.3 and the second clamping group 4.4 are in a co-clamping state, and when the gear ring unit 5.1 is located on the second area surface during its rotation, the first clamping group 4.3 and the second clamping group 4.4 are in a single clamping state;

[0038] Specifically, the box frame 1 is actually a cubic frame of a box-shaped structure, the plate surface of the bottom plate 2 is parallel to the horizontal plane, and railings 3.4 whose length direction lines are parallel to the horizontal plane are fixed to the front and rear side surfaces of the box frame 1, and the plate body of the railing 3.4 movably penetrates the side of the supporting plate 3.1, and the supporting plate 3.1 can move along the length direction of the railing 3.4, and the end of the supporting plate 3.1 is spirally installed with a limit pin 3.5 that can be squeezed with the railing 3.4, the plate surface of the supporting plate 3.1 is parallel to the horizontal plane, and the length direction line of the supporting plate 3.1 is perpendicular to the length direction line of the railing 3.4 on the same horizontal plane, and the length direction line of the slideway opening 3.2 is the same as the length direction line of the supporting plate 3.1, and the supporting box 3.3 can move in the length direction of the slideway opening 3.2;

[0039] The gear ring unit 5.1 can change the clamping state of the clamping assembly 4 during the rotation process, wherein the first clamping group 4.3 and the second clamping group 4.4 each have two states, namely, clamping and loosening. When the first clamping group 4.3 and the second clamping group 4.4 are both in the clamping state, the first clamping group 4.3 and the second clamping group 4.4 are in the same clamping state, that is, the clamping assembly 4 is in the same clamping state;

[0040] When only one of the first clamping group 4.3 or the second clamping group 4.4 is in the clamping state, the first clamping group 4.3 and the second clamping group 4.4 are in a single clamping state, that is, the clamping assembly 4 is in a single clamping state;

[0041] In actual use, the clamping component 4 in the single clamping state is fully capable of clamping and fixing the male dog's limbs. The clamping component is cyclically switched between the same clamping state and the single clamping state through the switching component, so that while keeping the clamping tightness unchanged, different parts of the limbs can be squeezed alternately, thereby improving the comfort of clamping and fixing, reducing stimulation, and helping to reduce the emotional fluctuations of the male dog during the detection process and promoting the smooth progress of the detection work.

[0042] In another embodiment provided by the present invention, slide grooves 3.21 adapted to be engaged with the support box 3.3 are provided on the inner walls on both sides of the slide opening 3.2, the length direction of the slide groove 3.21 is the same as the length direction of the slide opening 3.2, and a plurality of evenly distributed tooth surface grooves 3.22 are provided on the side wall surface of the slide groove 3.21, and the groove length direction line of the tooth surface groove 3.22 is perpendicular to the horizontal plane, and the support box 3.3 can slide in the slide groove 3.21, and the slide groove 3.21 provides support and limit for the support box 3.3 in the vertical direction in the slide opening 3.2;

[0043] During actual use, the support box 3.3 needs to move in the width direction within the box frame 1. At this time, the support box 3.3 can be moved in the length direction of the slide groove 3.21 within the slide opening 3.2. Similarly, when the support box 3.3 needs to move in the length direction within the box frame 1, the support plate 3.1 can be moved in the length direction of the railing 3.4, thereby indirectly realizing the movement of the support box 3.3 in the length direction within the box frame 1.

[0044] In another embodiment provided by the present invention, the first clamping group 4.2 includes two pushing columns 6 movably plugged and installed on two opposite frame surfaces of the moving frame 4.2, the axis of the pushing column 6 is parallel to the horizontal plane, the axis of the pushing column 6 is perpendicular to the frame side of the moving frame 4.2, the pushing column 6 can move axially on the moving frame 4.2, and one end of the pushing column 6 located outside the moving frame 4.2 is connected to the moving frame 4.2 through a spring 7;

[0045] When the spring 7 is in a naturally extended state, the insertion end of the squeezing and pushing column 6 is flush with the inner wall surface of the moving frame 4.2. At this time, the first clamping group 4.2 is in a loose state, and the squeezing force value between the squeezing and pushing column 6 and the male dog's limbs is at a minimum state. Similarly, when the squeezing force between the squeezing and pushing column 6 and the male dog's limbs is sufficient to limit and fix the male dog's limbs, the first clamping group 4.2 is in a clamping state. The structure of the first clamping group 4.2 is the same as that of the second clamping group 4.4. The structure of the first clamping group 4.2 and the switching method of the second clamping group 4.4 between the loose state and the clamping state are the same. The first clamping group 4.2 and the second clamping group 4.4 have different contact positions with the male dog's limbs in the clamping state.

[0046] Among them, one end of the pushing column 6 located outside the moving frame 4.2 is movably installed with a support wheel 8 that can roll with the inner wall surface of the gear ring unit 5.1, and one end of the pushing column 6 located inside the moving frame 4.2 is fixed with a V-shaped groove block 13, and a buffer pad 14 is fixed in the groove body of the V-shaped groove block 13. The buffer pad 14 is preferably an elastic rubber pad with anti-slip grooves, so as to increase the friction between the male dog's limbs, and the groove body of the V-shaped groove block 13 can adapt to the male dog's limbs.

[0047] In another embodiment provided by the present invention, the gear ring unit 5.1 includes a gear ring body 5.11, which is sleeved on the outside of the clamping assembly 4, and two mirror-distributed groove surfaces 5.12 are provided on the circumferential inner ring wall surface of the gear ring body 5.11, and the groove side walls of the groove surface 5.12 are inclined wall surfaces, and the groove bottom wall of the groove surface 5.12 is parallel to the inner wall surface of the gear ring body 5.11, and the angle occupied by each groove surface 5.12 in the circumferential direction of the gear ring body 5.11 is sixty degrees, and the groove surface 5.12 is the second area surface of the gear ring unit 5.1, and the part of the inner wall of the gear ring body 5.11 except the groove surface 5.12 is the first area surface of the gear ring unit 5.1, and the first clamping group 4.2 and the second clamping group 4.4 can both contact the inner wall surface of the gear ring body 5.11;

[0048] Specifically, when the support wheel 8 on the first clamping group 4.2 is located at the second area surface of the gear ring unit 5.1, that is, the support wheel 8 is on the groove surface 5.12, the first clamping group 4.2 is in a loose state at this time, and when the support wheel 8 on the first clamping group 4.2 is located at the first area surface of the gear ring unit 5.1, that is, the support wheel 8 is on the actual inner wall surface of the gear ring body 5.11, the first clamping group 4.2 is in a clamped state at this time. The structure of the first clamping group 4.2 and the switching method of the second clamping group 4.4 between the loose state and the clamped state are the same, and will not be repeated;

[0049] That is to say, in actual use, as the gear ring body 5.11 rotates, the first clamping group 4.2 and the second clamping group 4.4 are in the following states in sequence: the first clamping group 4.2 is in a loose state and the second clamping group 4.4 is in a clamped state, the first clamping group 4.2 is in a clamped state and the second clamping group 4.4 is in a loose state, and both the first clamping group 4.2 and the second clamping group 4.4 are in a clamped state, thereby achieving the goal of maintaining the clamping tightness unchanged and being able to change the effect of alternating squeezing of different parts of the limbs.

[0050] In another embodiment provided by the present invention, the transmission unit 5.2 includes a first gear rod unit 5.21 meshed with one side of the gear ring unit 5.1, and the transmission unit 5.2 also includes a second gear rod unit 5.22 meshed with the other side of the gear ring unit 5.1, the first gear rod unit 5.21 and the second gear rod unit 5.22 both include a cross bar 9, the length direction line of the cross bar 9 is perpendicular to the length direction line of the support plate 3.1, both ends of the cross bar 9 extend out of the side ends of the support box 3.3, and the side of the cross bar 9 is provided with a limiting groove 10 for accommodating the gear ring unit 5.1, specifically, the side of the cross bar 9 facing the tooth surface of the gear ring body 5.11 is provided with a limiting groove 10, and a plurality of evenly distributed ratchet members 11 are movably installed in the limiting groove 10, and the ratchet member 11 can mesh with the gear ring body 5.11 in a counterclockwise rotating state for transmission;

[0051] Specifically, the ratchet member 11 includes a ratchet block, which is movably hinged to the limit groove 10, and the hinged position between the ratchet block and the limit groove 10 is connected by a torsion spring. The ratchet block has an upright state perpendicular to the bottom of the limit groove 10, and an evasive state in contact with the bottom of the limit groove 10. In the case of self-heating, the ratchet block maintains an upright state perpendicular to the bottom of the limit groove 10.

[0052] Furthermore, the profile surface of the through-opening 4.1 is a long strip, the left and right ends of the through-opening 4.1 are both located in the slideway opening 3.2, the length direction of the through-opening 4.1 is parallel to the length direction line of the crossbar 9, and the inner walls on both sides of the through-opening 4.1 are provided with limit blocks 4.5 fixed to the bottom of the moving frame 4.2, so that the moving frame 4.2 can move along the length direction of the through-opening 4.1;

[0053] In actual use, for example, when the moving frame 4.2 moves toward the left end of the through opening 4.1, the gear ring body 5.11 also moves synchronously. During the movement, the ratchet piece 11 on the first gear rod unit 5.21 remains in an upright state, and the upright ratchet piece 11 is engaged with the gear ring body 5.11, thereby generating resistance to the gear ring body 5.11 sliding in the limiting groove 10 of the first gear rod unit 5.21, and the ratchet piece 11 on the second gear rod unit 5.22 is subjected to the tooth body force of the gear ring body 5.11. The ratchet member 11 in the avoidance state will not mesh with the gear ring body 5.11, so that the gear ring body 5.11 can slide smoothly in the limiting groove 10 of the second gear rod unit 5.22. Therefore, when the gear ring body 5.11 moves at the left end of the through hole 4.1, the gear ring body 5.11 actually rolls along the limiting groove 10 of the first gear rod unit 5.21, and the gear ring body 5.11 slides in the limiting groove 10 of the second gear rod unit 5.22, and the gear ring body 5.11 rotates counterclockwise.

[0054] Similarly, when the moving frame 4.2 moves toward the right end of the through opening 4.1, the ratchet piece 11 on the second gear rod unit 5.22 remains in an upright state, and the ratchet piece 11 in the upright state meshes with the gear ring body 5.11, thereby generating resistance to the sliding of the gear ring body 5.11 in the limiting groove 10 of the second gear rod unit 5.22, and the ratchet piece 11 on the first gear rod unit 5.21 is switched to an avoidance state when it is subjected to the force of the teeth of the gear ring body 5.11, and the ratchet piece 11 in the avoidance state will not mesh with the gear ring body 5.11, thereby 5.11 can slide smoothly in the limiting groove 10 of the first gear rod unit 5.21. Therefore, when the gear ring body 5.11 moves to the right end of the through-opening 4.1, the gear ring body 5.11 actually rolls along the limiting groove 10 of the second gear rod unit 5.22. The gear ring body 5.11 slides in the limiting groove 10 of the first gear rod unit 5.21, and the gear ring body 5.11 still rotates counterclockwise; that is to say, during the reciprocating movement of the gear ring body 5.11 along the through-opening 4.1, the gear ring body 5.11 always maintains a counterclockwise rotation state.

[0055] In another embodiment provided by the present invention, the cross bar 9 is movably installed on the side of the support box 3.3, and both ends of the cross bar 9 are fixed with plugs 12 that can mesh with the tooth surface groove 3.22. When the plug 12 meshes with the tooth surface groove 3.22, the position of the support box 3.3 in the slideway opening 3.2 is locked. When the plug 12 is separated from the tooth surface groove 3.22, the support box 3.3 can slide in the slideway opening 3.2.

[0056] In actual use, after the position of the supporting box 3.3 in the slide opening 3.2 is determined, the gear ring body 5.11 is rotated clockwise. At this time, the ratchet piece 11 on the first gear rod unit 5.21 and the ratchet piece 11 on the second gear rod unit 5.22 are in an upright state when in contact with the gear ring body 5.11, thereby accepting the meshing drive of the gear ring body 5.11, and then the plug 12 is meshed with the corresponding tooth surface groove 3.22, and the locking of the supporting box 3.3 on the slide opening 3.2 is completed. It should be further explained that even if the gear ring body 5.11 is in the reciprocating movement process along the through-opening 4.1, at least one plug 12 on the cross bar 9 is in a meshing state with the corresponding tooth surface groove 3.22, and the supporting box 3.3 can still be kept in a locked state on the slide opening 3.2.

[0057] In another embodiment provided by the present invention, the inner wall surface of the gear ring body 5.11 is a conical surface, the gear ring body 5.11 is a sleeve-shaped structure, the gear ring body 5.11 can move in the vertical direction of the limit groove 10, the axis of the gear ring body 5.11 is perpendicular to the horizontal plane, the inner wall surface of the gear ring body 5.11 is in contact with the support wheel 8, and in addition, the top of the gear ring body 5.11 is rotatably connected to the top of the support box 3.3 through a suspension assembly 18;

[0058] The suspension assembly 18 comprises an extension sleeve 18.1 which movably passes through the top of the support box 3.3, the inner diameter value of the extension sleeve 18.1 is the same as the minimum inner diameter value of the gear ring body 5.11, the bottom of the extension sleeve 18.1 is rotatably connected with the top of the gear ring body 5.11 on the same axis, the outer circumferential surface of the extension sleeve 18.1 extending from the top of the support box 3.3 is provided with a plurality of evenly distributed annular grooves 18.2, and the two sides of the extension sleeve 18.1 are respectively provided with protrusions 18.3 fixed to the top of the support box 3.3, and the side of the protrusion 18.3 is spirally penetrated with a screw 18.4 which can be engaged with the side of the extension sleeve 18.1, and when the end of the screw 18.4 is engaged with the annular groove 18.2, the extension sleeve 18.1 is limited and fixed in the vertical direction, and the suspension assembly 18 is in a locked state;

[0059] In actual use, the position of the support plate 3.1 is adjusted in the lateral direction of the box frame 1, and then the position of the support box 3.3 on the slideway opening 3.2 is adjusted so that the through opening 4.1 corresponds to the position of the male dog's limbs. Then, the position of the support plate 3.1 on the box frame 1 is fixed, and the position of the support box 3.3 on the slideway opening 3.2 is fixed. Then, the male dog's limbs are inserted into the corresponding through opening 4.1, and the bottom of the male dog's limbs contacts the bottom plate 2. At this time, by lowering the toothed ring body 5.11 downward, Movement, since the inner wall surface of the gear ring body 5.11 is a conical surface, the pushing column 6 moves toward the male dog's limbs under the pressure of the inner wall surface of the first area of ​​the gear ring body 5.11. When the pushing column 6 is blocked by the male dog's limbs and cannot move further, the pushing column 6 is in a clamping state. It should be particularly noted that at this time, all the pushing columns 6 on the clamping assembly 4 are in a clamping state with the male dog's limbs, and then the suspension assembly 18 is switched to a locked state, so that the height position of the gear ring body 5.11 can be determined;

[0060] When the male dog's limbs swing back and forth in the through hole 4.1, the clamping assembly 4 still maintains a firm clamp on the male dog's limbs, and at the same time provides driving force for the counterclockwise rotation of the gear ring body 5.11. At this time, the switching assembly 5 cyclically switches the clamping assembly 4 between the same clamping state and the single clamping state.

[0061] In another embodiment of the present invention, a plurality of auxiliary wheels 17 are rotatably mounted on the circumferential surface of the wheel body of the support wheel 8.
