Description

Technical Field

[0001] The utility model relates to the technical field of needle-free syringes, in particular to a multi-nozzle device for a veterinary needle-free syringe. Background Art

[0002] A needle-free syringe is a medical device that abandons the traditional needle injection method and instead uses high-pressure jet technology to deliver drugs into the body, thus achieving the effect of painless injection. This type of needle-free syringe is currently used in a wide range of fields, including the veterinary field, thus avoiding stress reactions in animals during injection. Traditional needles often only perform single-point puncture injections because they can cause wounds and pain in the human body. However, due to the painless and non-traumatic characteristics of needle-free syringes, they can use multiple injection nozzles to implement simultaneous multi-point injections. This method can better diffuse the drug solution and thus stimulate the drug effect more quickly.

[0003] In view of this, a design or technical improvement is now proposed to solve the above problems.

[0004] The above content is only used to assist in understanding the technical solution of the present invention and does not constitute an admission that the above content is the closest prior art. Utility Model Content

The upper section of the diverter nozzle is provided with a main flow pipe, and the lower section is evenly distributed with multiple groups of diverter tubes that are connected to the main flow pipe. When the connecting sleeve is connected to the needle-free syringe main body, the main flow pipe is connected to the injection port of the needle-free syringe main body.

[0008] Furthermore, a cleaning component for cleaning the main pipe and the diverter pipe is provided in the diverter nozzle.

[0009] Furthermore, the cleaning assembly includes a flow box arranged between the main flow pipe and the needle-free syringe body and used to connect the two, a piston cylinder connected to the side end of the flow box, a piston rod sealingly sliding in the piston cylinder, and a flow extraction tube connected to the piston cylinder.

[0010] Furthermore, the bottom of the flow box is connected to the main pipe, and the upper end is connected to a connecting tube for docking with the injection port of the needle-free syringe body. The interior of the flow box is provided with a baffle that is rotated by a movable shaft to seal the connecting port between the piston cylinder and the flow box. A torsion spring sleeved on the movable shaft is provided between the baffle and the side wall of the flow box; after the baffle is rotated ninety degrees, the connecting port between the connecting tube and the flow box can be blocked.

[0011] Furthermore, a filter box is provided between the suction pipe and the piston cylinder and is in communication with the two. A partition frame is provided inside the filter box, and a filter plate is provided on a side of the partition frame close to the suction pipe.

DETAILED DESCRIPTION

[0028] The technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. The embodiments in the application and the features in the embodiments can be combined with each other without conflict. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0029] As Figure 1-10 The multi-nozzle device of the veterinary needleless injector shown in the drawing, including needleless injector main body 1, also including connecting sleeve 2 which is detachably connected with the injection end of needleless injector main body 1, the end of connecting sleeve 2 away from needleless injector main body 1 is provided with shunt nozzle 21, the upper section of shunt nozzle 21 is provided with main flow pipe 22, and the lower section is uniformly provided with multiple groups of shunt pipes 23 which are in common communication with main flow pipe 22; when connecting sleeve 2 is connected with needleless injector main body 1, main flow pipe 22 is in communication with the injection port of needleless injector main body 1, through the movable clamping between connecting sleeve 2 and needleless injector main body 1, and then the injection port part of needleless injector main body 1 is in butt joint communication with main flow pipe 22, when needleless injector main body 1 injects, the liquid medicine will preferentially enter main flow pipe 22, and is shunted at the communication position of main flow pipe 22 and shunt pipe 23, so as to be divided into multiple strands and enter shunt pipe 23, so as to realize the effect of scattered point injection, and then the liquid medicine can be guaranteed to diffuse faster in the body, and the drug effect can be better excited.

[0030] In one embodiment, a cleaning component for cleaning the main pipe 22 and the diverter pipe 23 is provided in the diverter nozzle 21. Since the nozzle needs to be used for a long time, after the injection of the liquid medicine, there will be liquid medicine residue inside the diverter nozzle 21, and then the cleaning component needs to be used to perform targeted cleaning inside it to ensure the hygiene requirements for subsequent use.

[0031] In one embodiment, the cleaning component includes a flow box 3 arranged between the main pipe 22 and the needle-free syringe body 1 and used to connect the two, a piston cylinder 31 connected to the side end of the flow box 3, a piston rod 32 sealingly sliding in the piston cylinder 31, and a suction tube 33 connected to the piston cylinder 31. Since the channels of the main pipe 22 and the diversion pipe 23 inside the diversion nozzle 21 are narrow, it is difficult to clean the inside by conventional water flow. Therefore, by placing the suction tube 33 in clean water, and then pulling the piston rod 32, the water flow is sucked into the piston cylinder 31, and then by pushing the piston rod 32, the clean water sucked into the piston cylinder 31 is injected into the main pipe 22 and the diversion pipe 23 in a high-pressure form, thereby achieving an efficient cleaning effect.

[0032] In one embodiment, the bottom of the flow box 3 is connected to the main pipe 22, and the upper end is connected to a connecting pipe 4 for docking with the injection port of the needle-free syringe body 1. The interior of the flow box 3 is provided with a baffle 42 that is rotated by a movable shaft 41 to abut against and block the communication port between the piston cylinder 31 and the flow box 3. A torsion spring 43 that is sleeved on the movable shaft 41 is provided between the baffle 42 and the side wall of the flow box 3; after the baffle 42 is rotated ninety degrees, the communication port between the connecting pipe 4 and the flow box 3 can be blocked by the baffle. 42 is set, and then when the piston rod 32 sucks clean water into the piston cylinder 31, the baffle 42 closes the connecting port between the piston cylinder 31 and the flow box 3, so that no air will be sucked into the interior of the piston cylinder 31. When the piston rod 32 pushes clean water, the baffle 42 is pushed to rotate under the action of the high-pressure water flow, and then it will rotate ninety degrees to close the connecting port between the connecting pipe 4 and the flow box 3. Then the water flow will not be diverted from the connecting pipe 4, but will directly enter the main pipe 22 and the diversion pipe 23 for flushing.

[0033] In one embodiment, a filter box 5 is provided between the suction pipe 33 and the piston cylinder 31 to communicate with the two. A partition frame 51 is provided inside the filter box 5. A filter plate 52 is provided on the side of the partition frame 51 close to the suction pipe 33. Since the channels of the main pipe 22 and the branch pipe 23 are narrow, in order to prevent impurities in the clean water from being sucked into the piston cylinder 31 and then passing into the main pipe 22 and the branch pipe 23 to cause blockage, a filter box 5 is provided, and a filter plate 52 is provided in the filter box 5 to filter impurities in the water.

[0034] In one embodiment, a sponge block 6 is provided at one end of the partition frame 51 close to the piston cylinder 31. Through the provision of the sponge block 6, impurities in the water body can be further filtered. At the same time, when the piston rod 32 pushes the water flow in the piston cylinder 31, the water flow will generate resistance at the sponge block 6, so that the water flow rate flowing here is small, and most of the water flow is ejected through the diversion nozzle 21 by high-pressure jet. At the same time, no one-way flow component is provided at the filter box 5 to ensure that it can be backwashed by reverse water flow, thereby avoiding the accumulation of impurities.

[0035] In one embodiment, the inner wall of the connecting sleeve 2 and the outer wall of the injection end of the needle-free syringe body 1 are provided with a snap ring 7 that fits together and engages with each other. The structure of the snap ring 7 is similar to the snap structure of the pen barrel and pen cap, which makes the engagement and disassembly between the connecting sleeve 2 and the needle-free syringe body 1 convenient, and facilitates assembly and cleaning after use.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
