Description

Technical field:

[0001] The invention relates to the field of medicine, and more specifically to a posterior pituitary pulverizing mechanism for preparing posterior pituitary injection. Background technology:

[0002] Posterior pituitary injection is used for pulmonary and bronchial bleeding (such as hemoptysis), gastrointestinal bleeding (hematemesis, bloody stool), and is suitable for obstetrical induction of labor and postpartum uterine contraction and hemostasis. It is also effective for intestinal paralysis after abdominal surgery.

[0003] In the preparation process of the existing posterior pituitary injection, the pig's pituitary gland needs to be extracted, and the anterior and posterior pituitary lobes are separated after being soaked in acetone. The separated posterior pituitary needs to be dried. Since the structure of the posterior pituitary is relatively complete, during the constant-speed drying stage, the rate of water diffusion inside the posterior pituitary is greater than or equal to the surface evaporation rate. At this time, the evaporation of water is carried out on the surface of the posterior pituitary. The evaporation rate is controlled by the diffusion rate of steam through the surrounding air film, and the drying speed depends on the temperature difference between the surrounding hot air and the posterior pituitary. When the diffusion rate of water in the posterior pituitary can no longer keep the surface water saturated, the water diffusion rate becomes the controlling factor of the drying speed. At this time, the temperature of the posterior pituitary rises, the surface begins to harden, and the drying enters the deceleration drying stage, resulting in a long overall drying time. In this regard, the method of crushing first and then drying can be adopted, but this makes it difficult to separate the crusher from the sticky and wet posterior pituitary pulverized blocks. In this regard, there is a solution in the prior art that uses a scraper for cleaning, but this solution cannot be completed during the crushing process, and it is necessary to stop the machine or leave an idle time to facilitate scraper cleaning, which greatly affects the efficiency. The present invention proposes a posterior pituitary pulverizing mechanism for preparing posterior pituitary injection, which not only solves the separation of the pulverized blocks and the pulverizing structure, and ensures the output of the raw materials, but also completes the crushing first and then the drying, reducing the subsequent drying time, and more importantly, one side is cleaned and the other side is crushed at the same time, which is highly efficient. Summary of the invention:

Specific implementation method:

[0025] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings. It is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Embodiment 1, as Figure 1-4 The present invention provides a posterior pituitary lobe crushing mechanism for preparing posterior pituitary lobe injection, comprising:

[0027] A housing 11, wherein a crushing mechanism is disposed in the housing 11, and the crushing mechanism includes a first motor 12 and two rotating shafts;

[0028] The housing 11 is provided with a feed port 16 at the top and a discharge port 17 at the bottom. The rotating shaft is movably connected to the inside of the housing 11, and crushing rods are provided on the two rotating shafts. The crushing rods of the two rotating shafts cross to crush the posterior pituitary. The first motor 12 is connected to one side of the housing 11, and the first motor 12 drives the rotating shaft to rotate;

[0029] The rotating shaft is a double-layer sleeve structure, the inner tube 18 and the outer tube 19 are connected by a fixing rod 20, and a plurality of holes 21 are correspondingly provided on the inner tube 18 and the outer tube 19, and a metal rod 22 is inserted into the hole 21, and the metal rod 22 is cylindrical and fits with the hole 21. The top of the metal rod 22 extends out of the outer wall of the outer tube 19 to form a crushing rod, and the bottom of the metal rod 22 extends into the inner tube 18, and the bottom of the metal rod 22 is connected to a metal ball head 23, and a spring 24 is sleeved on the metal rod 22, and one end of the spring 24 is It is connected to the inner wall of the inner tube 18, and the other end is connected to the ball head. The rotating shaft extends out of the other side of the shell 11. A fixed tube 25 is fixedly connected to the other side of the shell 11. The metal ball head 23 is pressed against the outer wall of the fixed tube 25. The fixed tube 25 is laterally inserted into the inner tube 18. A recessed area 26 is provided on the outer wall of the fixed tube 25. The recessed areas 26 on the outer walls of the fixed tubes 25 inside the two rotating shafts are both provided on the other side of the opposite surface of the rotating shaft; the length of the metal rod 22 extending out of the outer wall of the outer tube 19 is equal to the depth of the recessed area 26.

[0030] In this embodiment: It should be noted that the inner wall of the shell 11 in this embodiment is a smooth stainless steel inner wall, and the discharge port 17 at the bottom is the lowest point.

[0031] In this embodiment, the double-layer sleeve structure serves to stabilize the metal rod 22 and maintain the stability of the metal rod 22 when it is extended and retracted in the hole 21 .

[0032] In this embodiment: the posterior pituitary is taken out after being soaked in acetone, put into the shell, and the first motor 12 is turned on. The first motor 12 drives the rotating shaft to rotate. When the rotating shaft of the double-layer sleeve structure is working, the fixedly connected inner tube 18 and outer tube 19 rotate at the same time, and the fixed tube 25 in the inner tube 18 is fixedly connected to the other side of the shell 11. The fixed tube 25 does not rotate. Under the influence of the elastic force of the spring 24, the metal ball head 23 at the bottom of the metal rod 22 moves along the outer wall of the fixed tube 25 and presses against the outer wall of the fixed tube 25. The length of the top of the metal rod 22 extending from the outer wall of the outer tube 19 is slightly less than the distance between the two rotating shafts. The metal rods 22 between the moving shafts are dislocated to cross-crush the posterior pituitary gland. The recessed areas 26 on the outer walls of the fixed tubes 25 inside the two rotating shafts are both arranged on the other side of the opposite surface of the rotating shafts, and the metal ball heads 23 of the metal rods 22 are pressed against the outer wall of the fixed tubes 25. The length of the top of the metal rod 22 extending out of the outer wall of the outer tube 19 is less than the distance between the two rotating shafts. When the metal rods 22 rotate to the other side, the metal ball heads 23 slide into the recessed areas 26 and then slide out of the recessed areas 26 under the influence of the elastic force of the springs 24. At this time, the metal rods 22 are extended and retracted in the holes 21, and the holes 21 are used to clean the rod walls of the metal rods 22. One side is cleaned and the other side is crushed at the same time, which is highly efficient.

[0033] In order to avoid more thoroughly removing the crushed pieces on the surface of the rotating shaft and the crushing rod.

[0034] The inner wall of the housing is provided with two soft scrapers 35, which are downwardly contacted with the other side of the opposite surface of the rotating shaft, that is, they are directed to the rotating shaft at the horizontal position of the recessed area.

[0035] The raw materials remaining on the metal rod after being crushed are on the other side of the rotating shaft, and the metal rod is retracted and expanded in the hole, and the hole is used to clean the rod wall of the metal rod. Since the length of the metal rod extending out of the outer wall of the outer tube is equal to the depth of the recessed area, at this time, the crushing rod is completely retracted into the rotating shaft. Using this gap, the soft scraper scrapes off the crushed blocks on the rotating shaft. At the same time, the two soft scrapers are set downward, and the crushed blocks fall downward without residue.

[0036] Furthermore, the two rotating shafts are a driving shaft 13 and a driven shaft 14 , one end of the driving shaft 13 is fixedly connected to the motor shaft of the first motor 12 via a coupling, and the surfaces of the driving shaft 13 and the driven shaft 14 are also meshedly connected with a limit gear 15 .

[0037] In this embodiment, the first motor 12 on the outside drives the driving shaft 13 to rotate. Since the two sets of limit gears 15 are meshed, the driven shaft 14 rotates in the opposite direction of the rotation direction of the driving shaft 13 under the gear transmission, thereby ensuring that the metal rods 22 on their respective surfaces squeeze the raw materials inward.

[0038] Embodiment 2, as Figure 5On the basis of Example 1, two layers of crushing mechanisms are provided in the shell 11, and a funnel-shaped collecting plate 27 is provided between the two layers of crushing mechanisms, and the collecting port of the collecting plate 27 points to between the two rotating shafts of the lower crushing mechanism.

[0039] In this embodiment: part of the raw materials cleaned by the upper crushing mechanism are crushed again by cross extrusion, and part of them fall to the crushing mechanism of the lower layer. After being crushed again by cross extrusion, the hole 21 is still used to clean the rod wall of the metal rod 22 to increase the crushing effect.

[0040] It should be noted that in the above embodiment, the interior of the inner layer tube of the spring is always in a compressed state, so that the crushing rod can continuously press against the surface of the fixed tube in the recessed area, thereby achieving the purpose of the expansion and contraction of the metal rod.

[0041] The first motor in the above embodiment is equipped with a reducer.

[0042] Embodiment 3, based on Embodiment 2, in order to improve efficiency and prevent the raw materials from staying on the collecting plate for too long, a set of scraping (pushing) mechanism for the collecting plate is added, specifically: Figure 6-7 ,

[0043] A window 28 is provided on the side wall of the shell, and a scraper 33 is provided in the window 28 for blocking. A first fixed seat 29 is provided on the shell outside the window 28, and an electric telescopic rod 31 is provided on the first fixed seat 29. The output end of the electric telescopic rod 31 is fixedly connected to one end of a guide rod 32, and the outer side of the guide rod 32 is fixedly connected to the scraper 33. The electric telescopic rod 31 pushes the scraper 33 along the upper surface of the aggregate plate.

[0044] When the electric telescopic rod 31 is not started, the scraper 33 blocks the window 28 to prevent the raw materials from overflowing. When there is too much raw material on the collecting plate, the electric telescopic rod 31 of the first fixed seat 29 is started, and the electric telescopic rod 31 pushes the guide rod 32 and then pushes the scraper 33; in this process, the scraper is pushed along the upper surface of the collecting plate, pushing the raw materials on the collecting plate into the collecting port, thereby increasing work efficiency.

[0045] It should be noted that the above-mentioned scraping (pushing) mechanism can be set not only on the collecting plate, but also on the bottom of the shell. The structure is the same and will not be repeated here.

[0046] In order to achieve efficient crushing, further, a second fixed seat 30 is provided on the shell, and a second motor is provided on the second fixed seat 30. The output shaft of the second motor is connected to a crushing knife 34. The crushing knife 34 covers the lower part of the collecting port of the collecting plate, and crushing is performed by the crushing knife 34.

The above display and description include the basic principles, main features and advantages of the present invention. Those skilled in the art should know that the present invention is not limited to the limitations of the above-mentioned embodiments.

Under the spirit and scope of the invention, the present invention may be further changed and optimized, and the improvements and optimizations made to the present invention are all within the scope of the invention to be protected.
