Description

Technical Field

[0001] The invention belongs to the technical field of veterinary vaccines, and in particular relates to a vaccine diluter and method for animal husbandry and veterinary medicine. Background Art

[0002] There are two types of vaccines for animal husbandry and veterinary medicine, liquid vaccines and freeze-dried vaccines. The specifications of the two vaccines are the same, and there is no difference in effect. The main difference lies in the validity period. The validity period of freeze-dried vaccines is longer than that of water injections, which is convenient for long-term storage and standby. The vaccination operation process requires drawing an appropriate amount of diluent from the dilution bottle and slowly adding it to the required amount of freeze-dried vaccine bottle to avoid impacting the vaccine and affecting the effect. Then shake the vaccine bottle to fully mix the freeze-dried vaccine and diluent until the vaccine is dissolved into a uniform liquid. Finally, use a new sterile syringe to draw the vaccine liquid from the diluted vaccine bottle for injection;

[0003] This dilution process dilutes the freeze-dried vaccine by adding a sufficient amount of diluent to the freeze-dried vaccine at one time. It is difficult to ensure that the amount of diluent is appropriate, and it is easy for there to be too much or too little diluent, which in turn leads to uneven distribution of the diluted vaccine components and causes local excessive concentration. At the same time, adding diluent to the freeze-dried vaccine and stirring and decomposing it can easily cause mechanical damage to the vaccine, resulting in damage to the vaccine activity. Summary of the invention

[0004] In order to solve the problem raised in the above background technology that one-time dissolution of freeze-dried vaccines may cause uneven distribution of vaccine components and easily damage the activity of the vaccine, the present invention provides a vaccine diluter and method for animal husbandry and veterinary medicine.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: A vaccine diluter for animal husbandry and veterinary medicine, comprising a supporting bracket, a fixed connecting ring distributed in a circumferential array is fixedly connected to the lower side of the supporting bracket, a ball head sliding rod is slidably connected to the fixed connecting ring, a motor mounting frame is hinged to the ball head sliding rod, a telescopic motor is installed in the motor mounting frame, a telescopic piston rod is installed on the upper side of the telescopic motor, an isolation dissolving net is fixedly connected to the telescopic piston rod, a dissolving barrel is slidably connected to the telescopic piston rod, a dissolving barrel is installed with a dissolving barrel cover, a dissolving diluent barrel is fixedly connected to the upper side of the dissolving barrel cover, a piston push rod is slidably connected to the dissolving diluent barrel, and an elastic film is installed in the piston push rod.

[0008] Preferably, a sliding connection ring is fixedly connected to the lower side of the dissolving and diluting liquid barrel, the sliding connection ring is slidably connected to the piston push rod, and a second return spring is arranged between the sliding connection ring and the piston push rod.

[0009] Preferably, symmetrically distributed sealing columns are fixedly connected to the lower side of the dissolving barrel cover, through holes corresponding to the sealing columns are opened on the telescopic piston rod, and the lower end of the sealing column is higher than the upper end of the telescopic piston rod.

[0010] Preferably, the telescopic piston rod is fixedly connected with shaking paddles that are staggered in a circumferential array, and a first return spring is arranged between the ball head sliding rod and the fixed connecting ring.

[0011] Preferably, the support bracket is fixedly connected with lower fixed blocks which are symmetrically distributed in the circumferential direction, the lower fixed block is rotatably connected with a lower rotating curved rod, and the upper side of the lower rotating curved rod passes through a lower connecting block which is rotatably connected with the lower connecting block.

[0012] Preferably, the lower connecting block is rotatably connected to the upper connecting block, the upper connecting block is rotatably connected to the upper connecting bent rod, the upper connecting bent rod is rotatably connected to the upper fixed block, and the upper fixed block is fixedly connected to the dissolving barrel.

[0013] Preferably, a shaking and rotating plate is fixedly connected to the lower side of the lower rotating curved rod, a torsion spring is arranged between the lower rotating curved rod and the lower fixed block, and the shaking and rotating plate is extruded and matched with the shaking paddle.

[0014] The present invention also provides a method for diluting a vaccine for animal husbandry and veterinary medicine, comprising the following steps:

[0015] S1. The existing operator puts the freeze-dried vaccine into the isolation dissolution net, starts the telescopic motor to drive the telescopic piston rod to slide upward, so that the freeze-dried vaccine in the telescopic motor contacts the elastic film, and then squeezes the piston push rod to slide upward, squeezes the diluent in the dissolving diluent barrel to flow into the dissolving barrel, and the telescopic piston rod slides up and down reciprocatingly. The elastic film controls the upward sliding distance of the piston push rod according to the freeze-dried vaccine in the isolation dissolution net, thereby controlling the amount of diluent in the dissolving diluent barrel flowing into the dissolving barrel;

[0016] S2, the telescopic piston rod slides upward while driving the shaking paddle to slide synchronously, and then the shaking paddle squeezes the shaking rotating plate, and drives the upper fixed block to slide downward through the lower rotating curved rod, the lower connecting block, the upper connecting block and the upper connecting curved rod, so that the dissolving barrel tilts, and as the shaking paddle continuously squeezes the shaking rotating plate, the dissolving barrel shakes as the telescopic piston rod slides upward, accelerating the contact and dissolution of the freeze-dried vaccine with the diluent;

[0017] S3. As the telescopic piston rod drives the shaking paddle to slide downward, the shaking paddle squeezes the shaking rotating plate again to rotate in the opposite direction, causing the dissolving barrel to tilt again, thereby causing the dissolving barrel to shake continuously. When the telescopic piston rod slides to the lower side of the dissolving barrel, the telescopic piston rod separates from the sealing column, and the freeze-dried vaccine dissolved by the diluent flows into the dilution chamber through the through hole on the telescopic piston rod and the dissolving liquid flow tube for proportional dilution.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The present invention cooperates with structures such as an isolation dissolving net and an elastic film, and a telescopic motor drives the telescopic piston rod and the isolation dissolving net to slide upward, so that the freeze-dried vaccine in the isolation dissolving net contacts the elastic film, and then drives the piston push rod to slide upward, squeezes the diluent in the dissolving diluent barrel to flow into the dissolving barrel, and dissolves the freeze-dried vaccine. The freeze-dried vaccine content in the isolation dissolving net is detected by the elastic film, and then the upward sliding distance of the piston push rod is controlled, and the amount of diluent entering the dissolving diluent barrel is controlled, so as to achieve the purpose of gradually dissolving the freeze-dried vaccine, ensure that the amount of diluent added during the vaccine dilution process is not too much or too little, and at the same time, the elastic material of the elastic film prevents the freeze-dried vaccine from being damaged due to excessive force, and ensures that the freeze-dried vaccine is completely dissolved;

[0020] The present invention cooperates with structures such as a shaking paddle and a shaking rotating plate, and drives the shaking paddle to slide upward through a telescopic piston rod, and then the shaking paddle squeezes the shaking rotating plate. The shaking rotating plate rotates to continuously shake the dissolving barrel, so that the diluent in the dissolving barrel shakes synchronously around the freeze-dried vaccine, thereby achieving the effect of accelerating the dissolution of the freeze-dried vaccine.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] like Figures 1 to 8As shown, the present invention provides a vaccine diluter for animal husbandry and veterinary medicine, including a support bracket 100, a fixed connection ring 206 distributed in a circumferential array is fixedly connected to the lower side of the support bracket 100, a ball head sliding rod 205 is slidably connected to the fixed connection ring 206, the ball head sliding rod 205 is hinged to a motor mounting frame 204, a telescopic motor 200 is installed in the motor mounting frame 204, a telescopic piston rod 201 is installed on the upper side of the telescopic motor 200, an isolation dissolution net 202 is fixedly connected to the telescopic piston rod 201, a dissolution barrel 300 is slidably connected to the telescopic piston rod 201, a dissolution barrel 300 is installed on the dissolution barrel 300, a dissolution barrel cover 301 is fixedly connected to a dissolving diluent barrel 303 on the upper side of the dissolving barrel cover 301, a piston push rod 309 is slidably connected to the dissolving diluent barrel 303, and an elastic film 311 is installed in the piston push rod 309.

[0032] A dissolving and diluting liquid cover plate 304 is installed on the upper side of the dissolving and diluting liquid barrel 303, and an extrusion piston plate 305 is slidably connected inside the dissolving and diluting liquid barrel 303. An extrusion spring 306 is arranged between the dissolving and diluting liquid cover plate 304 and the extrusion piston plate 305, and the outer diameter of the lower end of the piston push rod 309 is the same as the inner diameter of the isolation dissolving net 202.

[0033] A symmetrically distributed liquid inlet pipe 307 is fixedly connected to the outer contour of the dissolving and diluting liquid barrel 303 . The liquid inlet pipe 307 penetrates and is fixedly connected to the dissolving barrel cover 301 . A pressure valve is arranged at the lower end of the liquid inlet pipe 307 .

[0034] A sliding connection ring 308 is fixedly connected to the lower side of the dissolving and diluting liquid barrel 303 . The sliding connection ring 308 and the piston push rod 309 are slidably connected therethrough. A second return spring 310 is arranged between the sliding connection ring 308 and the piston push rod 309 .

[0035] The lower side of the dissolving barrel cover 301 is fixedly connected with symmetrically distributed sealing columns 302 , and the telescopic piston rod 201 is provided with through holes corresponding to the sealing columns 302 , and the lower end of the sealing column 302 is higher than the upper end of the telescopic piston rod 201 .

[0036] The above scheme is adopted: when the telescopic motor 200 drives the telescopic piston rod 201 and the isolation dissolving net 202 to slide upward, the elastic film 311 contacts the freeze-dried vaccine in the isolation dissolving net 202 to detect whether there is any freeze-dried vaccine in the isolation dissolving net 202, and then adjusts the distance that the piston push rod 309 slides upward according to the content of the freeze-dried vaccine in the isolation dissolving net 202, and then adjusts the amount of the diluent in the dissolving diluent barrel 303 flowing into the dissolving barrel 300. As the telescopic piston rod 201 slides upward and downward, a part of the freeze-dried vaccine in the isolation dissolving net 202 is dissolved, and then the telescopic piston rod 201 slides upward again. As a part of the freeze-dried vaccine in the isolation dissolving net 202 is dissolved, the content decreases, and then the distance that the piston push rod 309 slides upward is reduced until the freeze-dried vaccine in the isolation dissolving net 202 is completely dissolved, thereby preventing the freeze-dried vaccine in the isolation dissolving net 202 from contacting with excessive diluent, excessive dissolution, affecting the activity of the vaccine, and ensuring that there is no vaccine residue.

[0037] like Figure 1 and Figures 6 to 8 As shown, the telescopic piston rod 201 is fixedly connected with shaking paddles 203 which are staggered in a circumferential array, and a first return spring 207 is arranged between the ball head sliding rod 205 and the fixed connection ring 206.

[0038] The support bracket 100 is fixedly connected with lower fixed blocks 400 which are symmetrically distributed in the circumferential direction. The lower fixed blocks 400 are rotatably connected with lower rotating curved rods 401 . The upper side of the lower rotating curved rod 401 is penetrated and rotatably connected with a lower connecting block 403 .

[0039] The lower connecting block 403 is rotatably connected to the upper connecting block 404 , the upper connecting block 404 is penetrated and rotatably connected to the upper connecting curved rod 405 , the upper connecting curved rod 405 is rotatably connected to the upper fixed block 406 , and the upper fixed block 406 is fixedly connected to the dissolving barrel 300 .

[0040] A shaking rotating plate 402 is fixedly connected to the lower side of the lower rotating curved rod 401 , a torsion spring is provided between the lower rotating curved rod 401 and the lower fixed block 400 , and the shaking rotating plate 402 is pressed and matched with the shaking paddle 203 .

[0041] The above scheme is adopted: by shaking the paddles 203 arranged in a vertical direction and staggered in height in the circumferential direction, when the telescopic piston rod 201 drives the shaking paddles 203 to slide upward, the shaking rotating plates 402 at different positions are squeezed to rotate, thereby driving the dissolving barrel 300 to tilt toward the rotating shaking rotating plate 402, so that the dissolving barrel 300 is continuously shaken. At the same time, when the shaking paddles 203 slide downward, the shaking rotating plate 402 is squeezed to rotate in the opposite direction, so that the dissolving barrel 300 is lifted in the direction of the rotating shaking rotating plate 402, and then shaken again, thereby accelerating the contact and dissolution of the freeze-dried vaccine in the isolation dissolution net 202 with the diluent.

[0042] The present invention also provides a method for diluting a vaccine for animal husbandry and veterinary medicine, comprising the following steps:

[0043] S1. The existing operator puts the freeze-dried vaccine into the isolation dissolution net 202, starts the telescopic motor 200 to drive the telescopic piston rod 201 to slide upward, so that the freeze-dried vaccine in the telescopic motor 200 contacts the elastic film 311, and then squeezes the piston push rod 309 to slide upward, squeezes the diluent in the dissolving diluent barrel 303 to flow into the dissolving barrel 300, and the telescopic piston rod 201 slides up and down reciprocatingly, and the elastic film 311 controls the sliding distance of the piston push rod 309 according to the freeze-dried vaccine in the isolation dissolution net 202, thereby controlling the amount of the diluent in the dissolving diluent barrel 303 flowing into the dissolving barrel 300;

[0044] S2, the telescopic piston rod 201 slides upward and drives the shaking paddle 203 to slide synchronously, and then the shaking paddle 203 squeezes the shaking rotating plate 402, and drives the upper fixed block 406 to slide downward through the lower rotating curved rod 401, the lower connecting block 403, the upper connecting block 404 and the upper connecting curved rod 405, so that the dissolving barrel 300 is tilted, and as the shaking paddle 203 continuously squeezes the shaking rotating plate 402, the dissolving barrel 300 shakes as the telescopic piston rod 201 slides upward, accelerating the contact and dissolution of the freeze-dried vaccine with the diluent;

[0045] S3. As the telescopic piston rod 201 drives the shaking paddle 203 to slide downward, the shaking paddle 203 squeezes the shaking rotating plate 402 again to rotate in the opposite direction, so that the dissolving barrel 300 tilts again, and then the dissolving barrel 300 shakes continuously. When the telescopic piston rod 201 slides to the lower side of the dissolving barrel 300, the telescopic piston rod 201 separates from the sealing column 302, and then the freeze-dried vaccine dissolved by the diluent flows into the dilution chamber 500 through the through hole on the telescopic piston rod 201 and the dissolving liquid circulation tube 502 for proportional dilution.

[0046] The working principle and use process of the present invention:

[0047] Before the freeze-dried vaccine is diluted, it needs to be dissolved. First, the operator puts the freeze-dried vaccine into the isolation dissolution net 202, and then starts the telescopic motor 200, and then the telescopic motor 200 drives the telescopic piston rod 201 to slide upward, and then drives the isolation dissolution net 202 and the freeze-dried vaccine in the isolation dissolution net 202 to slide upward synchronously, and then the piston push rod 309 slides into the isolation dissolution net 202, and then the elastic film 311 in the piston push rod 309 contacts the freeze-dried vaccine in the isolation dissolution net 202, and then the telescopic piston rod 201 drives the piston push rod 309 to slide upward synchronously through the freeze-dried vaccine in the isolation dissolution net 202 and the elastic film 311, so that the piston push rod 309 squeezes the diluent in the dissolving diluent barrel 303, and then the diluent in the dissolving diluent barrel 303 flows into the dissolving barrel 300 through the liquid inlet pipe 307, and then the diluent contacts the freeze-dried vaccine in the isolation dissolution net 202, so that part of the freeze-dried vaccine in the isolation dissolution net 202 is dissolved. At the same time, as the telescopic piston rod 201 slides upward, the telescopic piston rod 201 and the sealing column 302 slide through, so that the through hole on the telescopic piston rod 201 is blocked, and part of the freeze-dried vaccine dissolved in the diluent will fall on the telescopic piston rod 201. After the telescopic motor 200 drives the telescopic piston rod 201 to slide upward to the limit position, the telescopic motor 200 drives the telescopic piston rod 201 to slide downward. As the telescopic piston rod 201 drives the isolation dissolution net 202 and the freeze-dried vaccine in the isolation dissolution net 202 to slide downward synchronously, the piston push rod 309 is reset as the telescopic piston rod 201 slides downward under the elastic force of the second reset spring 310, so that the diluent in the dissolving diluent barrel 303 stops entering the dissolving barrel 300. At the same time, under the elastic force of the extrusion spring 306, the extrusion piston plate 305 slides downward to keep the liquid level of the diluent in the dissolving diluent barrel 303 always in contact with the extrusion piston plate 305.

[0048] When the telescopic motor 200 drives the telescopic piston rod 201 to slide to the bottom of the dissolving barrel 300, it drives the telescopic piston rod 201 to slide upward again, and then repeats the above steps, contacts the remaining freeze-dried vaccine in the isolation dissolving net 202 through the elastic film 311, and then pushes the piston push rod 309 to slide in the dissolving diluent barrel 303, so that the diluent in the dissolving diluent barrel 303 flows into the dissolving barrel 300, so that the freeze-dried vaccine in the isolation dissolving net 202 contacts the diluent and dissolves, until the freeze-dried vaccine in the isolation dissolving net 202 is dissolved. At this time, the telescopic piston rod 201 drives the isolation dissolving net 202 to slide upward until the isolation dissolving net 202 slides upward to the limit, and the isolation dissolving net 202 will not push the piston push rod 309 to slide upward.

[0049] As the telescopic motor 200 drives the telescopic piston rod 201 to slide upward, it drives the shaking paddle 203 to slide upward, so that the shaking paddle 203 contacts the shaking rotating plate 402, squeezes the shaking rotating plate 402 to rotate around the lower fixed block 400, and then drives the lower rotating curved rod 401 to rotate synchronously, and through the lower connecting block 403 and the upper connecting block 404, the upper connecting curved rod 405 drives the upper fixed block 406 to slide downward, so that the dissolving barrel 300 tilts toward the rotating shaking rotating plate 402. Since the shaking paddles 203 are staggered in the circumferential array and distributed in the vertical direction, but the circumferential height gradually decreases, as the telescopic piston rod 201 slides upward, the shaking paddles 203 successively squeeze the shaking rotating plates 402 at different positions, so that the dissolving barrel 300 continuously moves toward different positions. The shaking and rotating plate 402 is tilted, so that the dissolving barrel 300 shakes as the telescopic piston rod 201 slides upward. When the shaking paddle 203 no longer squeezes the shaking and rotating plate 402, the shaking and rotating plate 402 is reset under the action of the torsion spring arranged between the lower rotating curved rod 401 and the lower fixed block 400, so that the dissolving barrel 300 recovers to be stable. As the telescopic motor 200 drives the telescopic piston rod 201 to slide downward, the shaking paddle 203 squeezes the shaking and rotating plate 402 again, so that the shaking and rotating plate 402 rotates in the opposite direction, and then one side of the dissolving barrel 300 is lifted through the lower rotating curved rod 401, the lower connecting block 403 and the upper connecting curved rod 405. As the telescopic piston rod 201 continues to slide downward, the shaking and rotating plates 402 at different positions rotate, so that the dissolving barrel 300 shakes again.

[0050] At the same time, as the dissolving barrel 300 shakes, the telescopic piston rod 201 is driven to swing synchronously, and then the telescopic motor 200 and the motor mounting frame 204 are driven to swing synchronously, so that the ball head sliding rod 205 rotates accordingly around the motor mounting frame 204 and slides along the fixed connecting ring 206. When the telescopic piston rod 201 slides to the sealing column 302 to separate, the freeze-dried vaccine in the isolation dissolving net 202 dissolved by the diluent flows through the grid on the isolation dissolving net 202 to the outside of the isolation dissolving net 202, and then flows into the dissolving liquid circulation tube 502 through the through hole on the telescopic piston rod 201, until it flows into the dilution chamber 500, so that the dissolved freeze-dried vaccine enters the dilution chamber 500 for further proportioning and dilution.

The conventional operator places the freeze-dried vaccine into the isolation dissolving net (202), starts the telescopic motor (200) to drive the telescopic piston rod (201) to slide upward, so that the freeze-dried vaccine in the telescopic motor (200) contacts the elastic film (311), thereby squeezing the piston push rod (309) to slide upward, squeezing the diluent in the dissolving diluent barrel (303) to flow into the dissolving barrel (300), and the telescopic piston rod (201) slides up and down reciprocatingly, and the elastic film (311) controls the upward sliding distance of the piston push rod (309) according to the freeze-dried vaccine in the isolation dissolving net (202), thereby controlling the amount of diluent in the dissolving diluent barrel (303) flowing into the dissolving barrel (300); S2, the telescopic piston rod (201) slides upward while driving the shaking paddle (203) to slide synchronously, and then the shaking paddle (203) squeezes the shaking rotating plate (402), and drives the upper fixed block (406) to slide downward through the lower rotating curved rod (401), the lower connecting block (403), the upper connecting block (404) and the upper connecting curved rod (405), thereby causing the dissolving barrel (300) to tilt. As the shaking paddle (203) continuously squeezes the shaking rotating plate (402), the dissolving barrel (300) shakes as the telescopic piston rod (201) slides upward, thereby accelerating the contact and dissolution of the freeze-dried vaccine with the diluent; S3. As the telescopic piston rod (201) drives the shaking paddle (203) to slide downward, the shaking paddle (203) squeezes the shaking rotating plate (402) again to rotate in the opposite direction, so that the dissolving barrel (300) tilts again, and then the dissolving barrel (300) is continuously shaken. When the telescopic piston rod (201) slides to the lower side of the dissolving barrel (300), the telescopic piston rod (201) is separated from the sealing column (302), and then the freeze-dried vaccine dissolved by the diluent flows into the dilution chamber (500) through the through hole on the telescopic piston rod (201) and the dissolving liquid circulation pipe (502) for proportional dilution.
