Example 1

The application provides a nasal drip device, which comprises a drip body 1 capable of adjusting the length of a tube body inserted into the nasal cavity of a child patient. Different sizes's syringe 4 can be connected selectively to dropping liquid body 1 for medical personnel can select syringe 4 and dropping liquid body 1 of different solution volume size to be connected, thereby carry the liquid medicine of different volumes to focus region in the nasal cavity effectively.

According to one embodiment shown in fig. 1, the drip body 1 comprises a connecting part 2 and a medicament release part 3. The connection part 2 can be hermetically connected with nipples of the syringes 4 having various sectional sizes so that inner pipes thereof are communicated with each other, and thus, a liquid medicine in the syringes 4 can be inputted into the inside of the dropping liquid body 1 through the connection part 2. One end of the connecting part 2 far away from the injector 4 is connected with a medicine releasing part 3 which can release medicine. The medicine releasing part 3 can be adjustably inserted into the nasal cavity of a patient, and the liquid medicine input by the connecting part 2 is directly sprayed on the whole focus area in a dispersed and released mode. The arc-shaped flexible filling part on the medicine releasing part 3 can limit the actual length of the medicine inserted into the nasal cavity, so that the medicine released by the medicine releasing part 3 just acts on a focus area, and the defects that the existing nasal drip tube cannot effectively control the insertion length when used in the crying process of children, and the nasal mucosa is damaged due to too long insertion easily or the medicine liquid cannot directly reach the focus due to too short insertion are overcome. The release head of the device is hemispherical, so that the uncomfortable intensity of a patient in the insertion process can be reduced, and the device is more favorable for completing effective drug release.

Preferably, the connection part 2 is connected to the nipple 41 of the syringe 4 in such a manner that the socket inner tube 211 is inserted into the nipple 41 while the socket outer tube 212 is socket-connected to the outside of the nipple 41, so that the nipple 41 communicates with the inner pipe of the dropping body 1 in such a manner that it is socket-connected without a gap from the input end 21 of the connection part 2. Specifically, the input end 21 is provided as a pipe having a double-walled pipe wall formed by a socket inner pipe 211 and a socket outer pipe 212, wherein the socket inner pipe 211 is placed in an inner pipe passage of the socket outer pipe 212, and a gap capable of being inserted into the nipple 41 exists between the socket inner pipe 211 and the socket outer pipe 212. Preferably, an inner tube for delivering the liquid medicine is disposed inside the inner tube 211, and an outer tube 212 contacting with a tube body portion of the inner tube 211 at an end away from the nipple 41 is sleeved outside the inner tube 211, so that the outer tube 212 is sleeved on the outer surface of the nipple 41 when the inner tube 211 is inserted into the opening of the nipple 41. It is further preferable that at least a part of the tube body of the socket inner tube 211 is suspended in the socket outer tube 212 in such a manner that the outer diameter of the tube body that can be inserted into the nipple is gradually increased, and the end of the socket inner tube 211 away from the nipple 41 is connected to the end of the socket outer tube 212. Preferably, the sleeve inner tube 211 and the sleeve outer tube 212 are in contact with each other, and one end of the tube combined into a single-layer integral tube is connected with the output end 22 of the connecting part 2. The liquid medicine injected into the connection part 2 through the nipple 41 of the syringe 4 is delivered to the guide tube 4 communicating with the medicine release part 3 through the output end 22. The liquid medicine input end of the release head 3 is integrally connected with the output end 22.

Preferably, the axial cross section of the inner socket tube 211 is substantially isosceles trapezoid, and the short side thereof is the end inserted into the opening of the nipple 41, and the long side thereof is the end contacting the outer socket tube 212. Further preferably, the outer wall of the inner sleeving tube 211 is provided with a plurality of sleeving bodies 213 which can be adapted to the nipples 41 with gradually increasing sizes step by step, so that the cross section of the axis of the inner sleeving tube 211 is substantially isosceles trapezoid. Preferably, the plurality of socket bodies 213 are arranged at intervals along the axial direction of the socket inner tube 211, and a spacing groove 214 is further arranged between two adjacent socket bodies 213. Preferably, the cross-section of the single socket body 213 is also isosceles trapezoid, so as to facilitate selective socket of nipples 41 of different sizes. When inner tube 211 is inserted into the inner tube of nipple 41, nipple 41 is gradually deformed and expanded as inner tube 211 is inserted into it, and the degree of deformation is limited by outer tube 212, so that nipple 41 is limited between inner tube 211 and outer tube 212.

Preferably, the medicine releasing part 3 at least comprises a releasing head 31, a communicating pipe 32 and a flexible filling part 33. The liquid inlet end of the releasing head 31 is connected with a communication pipe 32, and the end of the communication pipe 32 far away from the releasing head 31 is communicated with the output end 22 of the connecting part 2. Preferably, the delivery passage with small diameter communicating with the inside of the connecting part 2 and the medicine releasing part 3 is provided in such a manner that the remaining amount of the medicine solution can be reduced. Through setting up inside transfer passage to less diameter, can fully release the liquid medicine that syringe 4 absorbed to the nasal cavity, the volume of remaining liquid medicine in the internal conduit after greatly reduced device accomplishes the liquid medicine and carries. The surface of the discharge head 31 remote from its inlet end is connected to a flexible filler 33 extending in its radial direction. Preferably, the flexible filling part 33 is extended from the arc-shaped surface edge of the release head 31 with the same surface curvature.

Preferably, at least part of the body of the flexible filling body 33 connected to the release head 31 is adapted to be inserted into the nostril of the child, the flexible filling body 33 being provided with an arc bent radially inwards of the release portion 3, such that the flexible filling body 33 defines the operative position of the release head 31. In use, the flexible filling body 33 can only be inserted into the nostril of the child patient with the front end part body having the largest cross section along with the release head 31, so that the length of the release head 31 inserted into the nostril can be limited, and the connecting tube 32 which is too long can be prevented from being inserted into the nostril along with the release head 31. Preferably, the surface of the discharge head 31 far from the liquid inlet end thereof is opened with a plurality of discharge holes 311 communicated with the internal pipeline thereof, so that the liquid medicine entering the discharge head 31 can be discharged dispersedly through the discharge holes 311. The discharge holes 311 are opened on the curved surface of the discharge head 31 in a multi-radius circumferential distribution manner so that the liquid medicine can cover the entire nasal cavity lesion area in a manner of a large spray area. Preferably, the releasing head 31 is further provided with a hemisphere 312 capable of filling partial volume of the inner cavity thereof, so that only one communication chamber with arc-shaped gaps and layers communicated with the releasing hole 311 exists in the releasing head 31, thereby effectively reducing the volume of the remained liquid medicine possibly existing in the releasing part 3 and sufficiently avoiding the waste of the liquid medicine when the device is used.
