Description
Technical field
This utility model relates to a kind of nasal feeding injector.
Technical background
Current nasal feeding injector is generally the device adopting syringe and nasal feeding tube composition, and in nasal feeding operating process, syringe needs suction alternately and injection food, and cause whole nasal feeding complex operation, nasal feeding is chronic.
Utility model content
Technical problem to be solved in the utility model is just to provide a kind of nasal feeding injector, and solving existing nasal feeding injector needs suction alternately and injection food, causes whole nasal feeding complex operation, the technical problem that nasal feeding is chronic.
For solving the problems of the technologies described above, this utility model adopts following technical scheme:
A kind of nasal feeding injector, comprise body and be located at the syringe in body, described syringe comprises body, stretches into the piston in body and connects the worm screw of piston, the worm gear be connected with worm thread and the rotating shaft connecting worm gear is provided with in body, described rotating shaft is provided with away from one end of worm gear the driving device that drive shaft rotates, described body is provided with perfusion cup, described perfusion cup is by pipeline communication tube cavity, described body is provided with the connection tube of communicating pipe intracoelomic cavity, and described connection tube stretches out body and connects nasal feeding tube.
Further, the wall of cup of described perfusion cup is provided with graduation mark, and described pipeline is provided with stop valve.
Further, the drainage screen covering perfusion cup rim of a cup is provided with in described perfusion cup.
Further, described driving device is hand-operated wheel.
Further, described driving device is servomotor.
The beneficial effects of the utility model are:
1, spoon meat can inject in the body of syringe by perfusion cup, and syringe no longer needs the operation of aspirating and injecting that hockets, and simplifies the operating time of nasal feeding operating process and nasal feeding;
2, the piston in syringe is driven by turbine and worm, makes the injection process of nasal feeding more be easy to control, and stable nasal feeding injection is safer to patient.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, this utility model is described further:
Fig. 1 is the structural representation of a kind of nasal feeding injector of this utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is elaborated.
As shown in Figure 1, a kind of nasal feeding injector of this utility model, the syringe 2 comprising body 1 and be located in body 1, syringe 2 comprises body 21, stretch into the piston 22 in body 21 and connect the worm screw 23 of piston 22, body 21 and piston 22 fit structure of syringe 2 are injector for medical purpose, the worm gear 3 be threaded with worm screw 23 and the rotating shaft 4 being connected worm gear 3 is provided with in body 1, rotating shaft 4 is provided with away from one end of worm gear 3 driving device 5 that drive shaft 4 rotates, when rotating shaft 4 adopts manual actuation, driving device 5 is hand-operated wheel, manually the slow drive shaft 4 of rocking-turn hand-operated wheel is rotated, when rotating shaft 4 adopts motorized motions, driving device 5 is servomotor, servomotor adopts slow-speed of revolution servomotor, body 1 is provided with the gauge tap controlling servomotor rotating, body 1 is provided with perfusion cup 6, perfusion cup 6 is communicated with body 21 inner chamber by pipeline 61, body 21 is provided with the connection tube 7 being communicated with body 21 inner chamber, connection tube 7 stretches out body and connects nasal feeding tube 8.
The wall of cup of perfusion cup 6 is provided with graduation mark 62, and pipeline 61 is provided with stop valve 63, by closing stop valve 63, just can put into the spoon meat of required groundwater increment to perfusion cup 6 according to graduation mark 62, realizing quantitative perfusion.
The drainage screen 64 covering perfusion cup 6 rim of a cup is provided with in perfusion cup 6, particle filtering in the food of allotment can be fallen formed agranular spoon meat by drainage screen 64, prevent patient's stomach tube from blocking, perfusion cup 6 is provided with bowl cover 65, by arranging bowl cover health more, open or close perfusion cup 6 also convenient.
Work process of the present utility model is:
First, accessory drive 5 drive shaft 4 makes piston 22 be positioned at the most proximal end of close body 21 opening, close stop valve 63, spoon meat is injected in perfusion cup 6, food groundwater increment is determined according to graduation mark 62, then stop valve 63 is opened, stop valve 63 is closed after filling food in body 21, driving device 5 drive shaft 4 rotates forward, due to the effect of worm gear 3 and worm screw 23, drive piston 22 towards stretching into the direction motion of body 21 until piston 22 is positioned at the distalmost end away from body 21 opening, spoon meat in body 21 is clamp-oned in the stomach of patient by nasal feeding tube 8, again driving device 5 again drive shaft 4 reverse, drive piston 22 towards stretching out the direction motion of body 21 until piston 22 is positioned at the most proximal end near body 21 opening, open stop valve 63, repeat above-mentioned filling process again, until the spoon meat in perfusion cup 6 all pours into complete, achieve nasal feeding process can seriality operate, simplify the operating time of nasal feeding operating process and nasal feeding.
Be described with regard to this utility model preferred embodiment above, but can not be interpreted as it is limitations on claims.This utility model is not only confined to above embodiment, its concrete structure allows to change, those skilled in the art can make various change and distortion according to this utility model, only otherwise depart from spirit of the present utility model, all belong to the scope that this utility model claims define.
