Detailed Description
The veterinary nasal drip device shown in fig. 1 can realize the effect of continuously controllable spraying and outputting, and is controlled according to the time length and the pressing degree of the pressing wrench. The pressing state of the wrench is shown in fig. 2, and after the wrench is pressed, the liquid medicine in the volumetric cylinder can be automatically sprayed out. The operation is very simple and controllable. The capacity cylinder is directly used as a handle to save the number of parts, the overall complexity is reduced, the wrench structure is simplified to be as shown in the structure of fig. 3, and the overall cost is lower.
Example 1: the nose drip device related to the embodiment mainly comprises a pressurizing control mechanism and an injection control mechanism.
Wherein, the pressurizing control mechanism is designed in the capacity cylinder, the appearance is shown in fig. 1, and the internal structure is shown in fig. 5. As can be seen in fig. 5, the body of the cartridge comprises a barrel, a top plate and a bottom plate. The piston and the thrust spring seat are sleeved in the capacity cylinder, and are fixed together through the connecting rod, so that double-layer tightness is achieved. The area between the piston and the top plate is a liquid medicine chamber for containing liquid medicine. The area between the thrust spring seat and the bottom plate is a thrust spring chamber, and a thrust spring is connected between the thrust spring seat and the bottom plate in the thrust spring chamber. The area between the piston and the thrust spring chamber is a transition area, the liquid medicine chamber and the thrust spring chamber can be effectively prevented from having a contact opportunity by arranging the transition area, the range of the transition area can be controlled by changing the length of the connecting rod through the through hole, and further the arrangement of preventing the liquid medicine chamber and the thrust spring chamber from being always out of contact can be achieved.
As can be seen from fig. 5, the bottom center of the thrust spring seat is provided with a block shell, the block shell comprises an inner cavity and a hole of the bottom plate, and the width of the inner cavity is larger than the width of the hole. The rotation stop block is sleeved in the stop block shell and connected with the sleeve rod, and the sleeve rod penetrates through the hole, so that the sleeve rod can rotate in the stop block shell but cannot fall off, and the sleeve rod can drive the thrust spring seat to move downwards when moving downwards.
As can be seen from fig. 5, the center of the base plate is provided with a hole and fixedly installed with an internally threaded sleeve, and an externally threaded sleeve is axially installed in the internally threaded sleeve, so that the externally threaded sleeve can be rotated into and out of the internally threaded sleeve. The sleeve rod is sleeved inside the externally threaded sleeve pipe, and the sleeve rod can slide freely.
As shown in fig. 8, a hand wheel is arranged at the outer end of the external threaded sleeve, and the external threaded sleeve can be controlled to rotate by pulling the hand wheel. The outer end of the externally threaded sleeve is also provided with a perforation, and one end of the rocker can be inserted into the perforation of the pipe. Meanwhile, a rod through hole is formed in the outer end of the loop rod, and one end of the rocker can be inserted into the rod through hole.
As shown in fig. 7, the thrust spring in the natural state presses the thrust spring seat, and thus the piston moves upward, and the thrust of the thrust spring pressurizes the liquid medicine chamber. In the process of spraying the medicine, when the spraying control mechanism is sprayed, the medicine liquid is sprayed, the piston is pushed by the thrust spring to move upwards slightly, otherwise, the piston is in a balanced state under the action of the pressure in the medicine liquid chamber and does not move. When no liquid exists in the liquid medicine chamber, namely, after the thrust spring pushes the piston to reach the upper limit, the thrust spring reaches the maximum extension state. The push spring is compressed by the operation in the medicine adding process, and the push spring seat carries the sleeve rod to be located at the innermost end, and at the moment, the external thread sleeve pipe is controlled to move inwards by rotating the hand wheel, so that when the pipe perforation of the external thread sleeve pipe corresponds to the rod perforation position of the sleeve rod, one end of the rocker is inserted into the two perforation holes simultaneously, and the external thread sleeve pipe and the sleeve rod are connected into a whole, as shown in fig. 5. When the rocker is rotated, the external threaded sleeve can outwards move in the internal threaded sleeve, and meanwhile, the sleeve rod is driven to outwards move together, so that the thrust spring seat is driven to compress the thrust spring, and the piston is driven to downwards move, and the purpose of compressing and storing energy for the thrust spring is achieved. In the process of adding medicine, two medicine adding modes can be adopted, namely, the first mode is that the rocker is controlled to rotate to compress the thrust spring, meanwhile, the infusion tube is inserted (or inserted through the guide tube) into the liquid surface of the liquid medicine bottle, and the liquid medicine is sucked by the movement of the piston. The second mode is that after the thrust spring is compressed, i.e. the piston moves downwards to the proper position, the rocker is not removed (the liquid medicine chamber has no pressure, and the injection control mechanism is in an automatic open state), and the liquid medicine is injected into the infusion tube by adopting an injector. The supercharging adjustment is realized through the cooperation of the sleeve rod and the internal and external threaded sleeve, the operation is simple and convenient, the thrust spring can be compressed by simple operation before charging, and the purpose of supercharging is realized by releasing the thrust spring after charging. And the charging operation is simple, and the charging process has no pressure.
As shown in fig. 4, the ejection control mechanism has a liquid inlet and a liquid outlet at the center of the top plate, and is mounted on the upper side of the liquid inlet and the liquid outlet. The principle of the injection control mechanism is to arrange an opening and closing valve and a spanner for controlling the opening and closing of the opening and closing valve, and the opening and the automatic closing of the opening and closing valve are realized by controlling the spanner. The outlet position of the injection control mechanism is connected with an infusion tube, a nose drop nozzle is arranged on a liquid inlet and outlet nozzle at the tail end of the infusion tube, and the nose drop nozzle can be replaced.
One configuration of the spray control mechanism may be as shown in fig. 9, and the spray control mechanism includes a nozzle arranged in the axial direction, the nozzle being fixed to the upper side of the liquid inlet/outlet port in the center of the top plate. A slide tube is sealed and sleeved in the inner cavity of the spray tube, so that the slide tube can slide in the spray tube.
The center of the slide tube is provided with a center hole, the far end of the slide tube is provided with a conical head, and the outlet of the center hole is positioned at the center of the conical head. A conical groove fixing block is fixedly arranged in the spray pipe, a conical groove is formed in the center of the conical groove fixing block, a rubber sealing gasket is sleeved in the conical groove, and the rubber sealing gasket preferably also comprises a conical groove, and corresponds to the conical head in position, so that after the sliding pipe moves upwards, the conical head of the sliding pipe can be extruded into the sealing rubber gasket, and the outlet of the central hole is sealed. The periphery of the cone groove fixing block is provided with a liquid draining side hole at the contact position of the periphery of the cone groove fixing block and the inner wall of the spray pipe, and the cone groove fixing block is fixed by a locking wire to prevent the cone groove fixing block from sliding.
As can be seen from the structure of the injection control mechanism shown in fig. 9, the lower surface of the slide tube receives pressure from the liquid medicine chamber, and an auxiliary spring is connected between the lower end of the slide tube and the top plate of the volumetric cylinder, so that the slide tube always receives upward pressure, and the conical head of the slide tube can be kept to be tightly extruded on the rubber sealing gasket, thereby preventing the liquid medicine from being sprayed out.
The lateral wall of the spray pipe is symmetrically fixed with the retaining shoulders, meanwhile, the lateral wall of the spray pipe is symmetrically provided with the strip-shaped sliding holes, and the retaining shoulders at two sides are sleeved in the strip-shaped sliding holes at two sides and can axially slide in the strip-shaped sliding holes. As shown in FIG. 9, the length of the slide tube is longer, and after the strip-shaped slide hole is arranged on the side wall of the spray tube, the slide tube can still seal the strip-shaped slide hole, so that the spray tube is kept in a always sealed state. As shown in fig. 1, a fixed rod is arranged on one side of the spray pipe or on the top plate of the capacity cylinder, and the upper end of the fixed rod is hinged with a spanner through a fixed seat. As shown in fig. 3, the wrench comprises two fork bars, the two fork bars are respectively supported on the upper sides of the two retaining shoulders, the two retaining shoulders can be driven to move downwards by pressing the wrench so as to drive the sliding tube to move downwards, so that the conical head of the sliding tube is in the same way as the rubber sealing gasket, and the high-pressure liquid medicine in the liquid medicine chamber is sprayed out. The quantitative controllable nasal drop spraying is carried out according to the patient degree of different individuals in the pig group, so that the pig group has a good treatment effect, and unnecessary liquid medicine waste can be saved.
Example 2: on the basis of embodiment 1, a pressurizing chamber is arranged at the lower end of the spray pipe, as shown in fig. 6, an outwardly protruding thrust plate is arranged at the lower end of the slide pipe, the edge of the thrust plate is a sealing sleeve, the thrust plate is sleeved in the pressurizing chamber in a sealing way, and an exhaust nozzle is arranged at the top of the pressurizing chamber. Thus, the outer diameter of the thrust plate at the bottom of the slide tube is obviously larger than the diameter of the central hole, the lower surface of the slide tube receives pressure from the liquid medicine chamber, the rubber sealing gasket receives pressure from the liquid medicine chamber, but the lower surface area of the slide tube is larger, more upward pressure is received, and the rubber sealing gasket only receives the pressure of the cross section of the central tube of the slide tube, so that the pressure difference received by the slide tube is DeltaF=F Bottom edge -F Cross section of central hole =P（S Bottom edge -S Cross section of central hole ) The sliding tube is always pressed upwards, so that the conical head of the sliding tube can be kept to be tightly extruded on the rubber sealing pad, and the liquid medicine is prevented from being sprayed out. The two retaining shoulders can be driven to move downwards by controlling the pressing wrench so as to drive the sliding tube to move downwards, so that the conical head of the sliding tube is in the same way as the rubber sealing gasket, and the high-pressure liquid medicine in the liquid medicine chamber is sprayedAnd (5) outputting. According to the embodiment, the matching relation of the spray pipe and the slide pipe is adopted, so that the slide pipe and the rubber sealing gasket in the conical groove fixing block can be tightly pressed together in an automatic state to achieve the aim of automatic sealing, and therefore other elastic components are not needed to participate, the structure is simplified, the components are optimized, and the failure rate is extremely low.
