Referring to fig. 1, an embodiment of a tree shrew drug delivery device 10 is provided for delivering drugs into the body of a tree shrew, wherein delivering drugs into the body of a tree shrew refers to delivering drugs into the esophagus, stomach or digestive tract through the esophagus or digestive tract end (anus) of the tree shrew. It should be noted that, the tree shrew drug feeder 10 provided in the present application may be applied to not only tree shrew, but also other animals having a body shape equivalent to or larger than the tree shrew, in other words, the tree shrew drug feeder 10 may also inject a drug into the body of an animal having a body shape larger than or equal to the tree shrew.

It is worth noting that in the prior art, there is no drug administration device specific to the tree shrew, and it is difficult for a human drug administration device to inject drugs into the body of the tree shrew. Human applicators often suffer from a number of drawbacks, such as the inability to screen large particles of the drug, increasing the difficulty factor of drug particles entering the tree shrew; for another example, the drug particles may have tackiness when exposed to water, blocking the tube openings such that the particles cannot enter the tree shrew; also for example, it is only suitable for humans, has low matching degree with tree shrew, and is easy to cause oesophageal damage to the tree shrew when administered; for another example, when the tree shrew is subjected to esophageal intubation, the possibility of inserting the intubation into the trachea cannot be avoided, if the medicine is pushed into the trachea, the animal can die, and the experiment is directly failed; also for example, the stomach tube delivery tube is thicker and longer, and in the case of frequent administration, the situation of damaging the esophagus of the tree shrew exists, which causes the esophagus to be inflamed and even bleeding, and causes the esophagus disease.

In order to provide a drug applicator for facilitating drug injection into a tree shrew, the tree shrew drug applicator 10 of the present application is provided, and in addition, the tree shrew drug applicator 10 of the present application can improve at least one of the above-mentioned problems.

In this embodiment, referring to fig. 1, 2 and 3 in combination, tree shrew dispenser 10 includes a dispensing assembly 100, a filling assembly 200 and a hose 300. The drug delivery assembly 100 is used for containing a drug and providing thrust to the drug so that the drug is injected into the tree shrew. The drug-filled assembly 200 is used to fill the interior of the drug delivery assembly 100 with a drug to ensure that there is sufficient drug within the interior of the drug delivery assembly 100. The hose 300 is used for extending into the tree shrew body to guide the drug directly into the preset position in the tree shrew body, so as to prevent the drug from adhering to the esophagus or the alimentary canal of the tree shrew and other positions of the tree shrew, thereby causing adverse reactions of the tree shrew.

Wherein the administration set 100 comprises a barrel 110, a pushing device 120, and a stirring device 130; a guide channel 111 is arranged in the cylinder 110, and a lead-out port 112 communicated with the guide channel 111 is arranged at the front end of the cylinder 110; the pushing device 120 is movably disposed in the guide channel 111, and is used for pushing out the medicine in the guide channel 111 from the outlet 112; the stirring device 130 is movably connected to the pushing device 120 for moving relative to the pushing device 120 to extend to the front end of the pushing device 120 for stirring the medicine in the guiding channel 111. The medicine-charging assembly 200 is coupled to the radially outer side of the cylinder 110 for introducing medicine into the guide passage 111. The hose 300 is connected to the end of the cylinder 110 and is connected to the outlet 112; the device is used for extending into a preset position in the tree shrew so as to guide the medicine to the preset position.

In the above description, when the medicine is introduced into the tree shrew, the medicine is introduced into the guide channel 111 through the medicine filling assembly 200, then the stirring device 130 is extended, and the medicine is stirred by the stirring device 130, so as to prevent the medicine particles from adhering together, and further prevent adverse reaction of the tree shrew caused by overlarge medicine volume; after the agitation is completed, the drug is pushed out of the delivery outlet 112 by the pushing device 120; the drug delivered from delivery port 112 may then be directed through hose 300 directly into the stomach of the tree shrew. The hose 300 passes through the esophagus of the tree shrew and directly enters the stomach of the tree shrew, so that damage to the esophagus of the tree shrew can be prevented, and meanwhile, the hose 300 can be used for preventing the tree shrew from generating excessive stress reaction, so that the success of drug administration is improved.

Of course, referring to fig. 5, in order to conveniently control the amount of the drug introduced into the tree shrew, a scale line 115 may be provided on the outer side of the barrel 110 to identify the amount of the drug in the guide channel 111, so that an operator can conveniently control the amount of the drug to be introduced according to the scale line 115.

Alternatively, in order to adapt the hose 300 to the tree shrew, the hose 300 is used to prevent the tree shrew from generating excessive stress reaction when the hose 300 is introduced into the tree shrew, and in this embodiment, the hose 300 has a length of 6cm-10cm and a pipe diameter of 1mm-3mm. In other words, the length of the hose 300 may take the value of 6cm, 7cm, 8cm, 9cm, 10cm, or the like; the tube diameter of the hose 300 may take a value of 1mm, 2mm, 3mm, or the like. Therefore, the length and the size of the hose 300 can be adapted to the body shape of the tree shrew, damage to other organs in the tree shrew caused by overlong hose 300 is prevented, and the situation that medicines cannot be effectively guided into preset positions in the tree shrew caused by overlong hose 300 can be prevented.

In this embodiment, the hose 300 may be made of a silicone rubber material, so that flexibility is ensured while softness is ensured, damage to the esophagus of the tree shrew caused by insertion and extraction of the hose 300 is avoided to the greatest extent, resistance of the tree shrew in administration is reduced, safety is high, comfort is high, and animal welfare is met. On the other hand, the design ensures the safety of frequent administration of the tree shrew.

In addition, in the present embodiment, the pushing device 120 includes a pushing rod 121 and a piston 122; the piston 122 is movably arranged in the guide channel 111 and is attached to the inner wall of the guide channel 111; one end of the push rod 121 is connected to the piston 122, and the other end extends from the end of the guide passage 111 away from the outlet 112. The stirring device 130 passes through the pushing rod 121 and is movably connected to the piston 122; the stirring device 130 is used to protrude to the front side of the piston 122 to be inserted into the guide passage 111 for stirring the medicine.

In the case where the piston 122 is disposed inside the guide passage 111, the piston 122 divides the guide passage 111 into two passages, one being a first passage 113 located at the front end of the guide passage 111 and located at the front side of the piston 122, and the other being a second passage 114 located at the rear end of the guide passage 111 and located at the rear side of the piston 122. Based on this, the outlet 112 communicates with the first passage 113, and the piston 122 can squeeze out the medicine inside the first passage 113 from the outlet 112 in the case where the piston 122 moves forward; in addition, the pushing rod 121 is disposed in the second channel 114, and the stirring device 130 may extend into the first channel 113 to stir the medicine in the first channel 113.

To facilitate the movable fit of the stirring device 130 with the piston 122, optionally, a channel is provided inside the pushing rod 121 through which the stirring device 130 passes. By setting the inside of the pushing rod 121 as a passage, excessive contact between the stirring device 130 and the pushing rod 121 can be prevented, and excessive friction between the stirring device 130 and the pushing rod 121 can be prevented, so that the stirring device 130 can be moved relative to the piston 122 conveniently. In other words, the push rod 121 may be regarded as a cylindrical structure, that is, the interior of the push rod 121 is hollow.

In addition, in order to facilitate pushing the pushing rod 121, a pushing head 123 is further disposed at an end of the pushing rod 121 away from the piston 122, and the pushing head 123 is substantially plate-shaped, so as to facilitate the operator to apply a force to the pushing head 123 and further facilitate pushing the pushing rod 121. It should be appreciated that in other embodiments of the present application, the shape of the pusher 123 may take other configurations, such as rod-shaped or block-shaped. Of course, in other embodiments, the setting of the pusher 123 may be omitted.

In the present embodiment, the stirring device 130 includes a connecting rod 131 and a stirring portion 132; the connecting rod 131 is movably connected to the piston 122 through the pushing rod 121, and the length of the connecting rod 131 is greater than that of the pushing rod 121; the stirring portion 132 is provided at an end portion of the connection rod 131 extending into the guide passage 111, and serves to stir the medicine inside the guide passage 111. The stirring part 132 is used for stirring the medicines to prevent particles from sticking together, and the granular medicines and water can be uniformly mixed, so that the medicine particles enter the tree shrew stomach in a dispersing mode, on one hand, the administration time is saved, and on the other hand, the medicine absorption is promoted.

The length of the connecting rod 131 is set to be greater than the length of the pushing rod 121, so that the connecting rod 131 at least partially extends out of the pushing rod 121, and further, an operator can conveniently apply acting force to the connecting rod 131, and further, the stirring portion 132 is conveniently controlled to extend into the first channel 113, and the stirring portion 132 is conveniently controlled to retract so as to be close to the piston 122.

When the medicine needs to be stirred, the operator applies a force to the connecting rod 131 so that the stirring portion 132 extends into the first passage 113, and then the stirring portion 132 stirs the medicine to the medicine viewing angle. The stirring portion 132 may be configured to stir the medicine in various ways, for example, by means of the connecting rod 131, the stirring portion 132 may reciprocate in the front-rear direction, so as to achieve the effect of stirring the medicine; for another example, the stirring portion 132 is rotated inside the first passage 113 by a time rotation force to the connection rod 131, and the purpose of stirring the medicine can be also achieved. Of course, the two modes can be simultaneously executed to achieve the purpose of stirring the medicine.

Alternatively, in the present embodiment, the connection rod 131 may be made of a stainless steel material, and of course, the connection rod 131 may be provided in a wire shape, a rod shape, or the like.

In addition, the stirring section 132 includes at least two stirring bars disposed to intersect, and at least one stirring bar is connected to the connecting bar 131. For example, in some embodiments of the present application, the stirring portion 132 is cross-shaped; for another example, the stirring section 132 is circular, and a stirring rod provided on the circular diameter line is connected to the connecting rod 131; also for example, the stirring rod encloses a special shape, etc.

Of course, referring to fig. 1 and 4 in combination, in order to facilitate the piston 122 to sufficiently push out the medicine in the first channel 113, optionally, a receiving groove 1221 is further provided on the front side of the piston 122; the receiving groove 1221 is adapted to the stirring portion 132, and serves to receive the stirring portion 132. After the stirring portion 132 completes stirring the medicine, the stirring portion 132 can be retracted into the accommodating groove 1221 through the connecting rod 131, and the accommodating groove 1221 can be filled through the stirring portion 132 due to the shape of the stirring portion 132 and the shape of the accommodating groove 1221, so that the piston 122 and the stirring portion 132 together form a shape adapted to the front end of the guide channel 111, and the medicine inside the guide channel 111 can be sufficiently extruded through the piston 122, thereby preventing the stirring portion 132 from affecting the movement of the piston 122 in the guide channel 111 and preventing the medicine from being wasted.

In this embodiment, the medicated assembly 200 includes a mixing cartridge 210, a feeder 230, and a connecting tube 220; a containing cavity 211 is arranged in the mixed medicine box 210, and a water injection port 212 communicated with the containing cavity 211 is arranged on one side of the mixed medicine box 210; the medicine feeder 230 is provided at the top of the mixing medicine box 210 for introducing medicine into the accommodating chamber 211; one end of the connection tube 220 is connected to the bottom of the mixing medicine box 210, and the other end is connected to the cylinder 110 and connected to the guide channel 111, and the connection tube 220 is used for guiding the medicine in the accommodating cavity 211 to the guide channel 111.

Wherein, water can be introduced into the cavity 211 through the water filling port 212, and medicine can be introduced into the cavity 211 through the medicine inlet 230, so as to realize the mixing of medicine and water.

It should be noted that, because the tree shrew is active and active, the power is strong, the aggressiveness is strong, the resistance is strong, if the tree shrew is held for a long time and the body of the tree shrew is damaged, in addition, the stress of the tree shrew is heavier than that of other various experimental animals, and once the stress reaction occurs, the death rate of the tree shrew is extremely high. Based on this, the medicine filling assembly 200 is disposed on the outer side of the cylinder 110, and can mix with water or other solutions while administering medicine, so that on one hand, the administration speed is increased, quick administration in a short time is completed, the holding time is reduced, and on the other hand, the mode of taking medicine with water for clinical human is simulated.
