Abstract
The utility model relates to a nasal feeding pump used for feeding food or medicine to patients. The utility model is composed of a suction tube, a discharge pipe, a pump body, a ball valve, a rubber bag, etc. Liquid diet and physic liquor can be fed to bodies of patients from nasal cavities through repeatedly squeezing the rubber bag. The utility model has the advantages of labor saving, time saving, no air entrance in stomachs, no back flow and no leakage. The utility model can also be used as an appliance for gastrolavage or clyster.
Description
This utility model is the utensil to patient's feed food.
To losing the heavy patient of swallow, in esophagus, carry liquid food, medicinal liquid and beverage with stomach tube by nasal cavity usually, nasal feeding that Here it is.Present nasal feeding is to suck liquid food, medicinal liquid etc. with syringe earlier, connects stomach tube then, slowly injects.When carrying out nasal feeding, to carry out in two steps, often will extract stomach tube repeatedly because of imbibition and adapter with syringe, connect, not only waste time and energy, people's operation is very difficult, and do not have because of syringe and stomach tube match and cause leakage, stomach tube easily advances problems such as air and liquid food refluence.
The task of this programme provides a kind of simplified control, and is time saving and energy saving, and not making gastric enter air does not have leakage, the special-purpose nasal feeding utensil that does not flow backwards.
This programme is achieved in that the pump housing of a T-shaped as the branch pipe tee connection joint is set, the anterior induction pipe that connects of the pump housing, and the rear portion is that capsule is taken over, in order to connect a spherical rubber bag tank, the bottom connects discharge pipe (in order to connect stomach tube).Pump housing middle part, induction pipe and capsule are established the inspiration valve chamber, interior dress inspiration ball valve between taking over.The inspiration valve chamber has through hole to communicate with the discharge valve chamber of bottom, and the indoor dress of dump valve is discharged ball valve.With inspiration valve chamber joint one needle beam is arranged in the capsule adapter, between discharge pipe and discharge valve chamber one needle beam is set also, the effect of needle beam is to prevent that ball valve from sealing passage when this place moves.
Nasal-feeding pump provides a kind of laborsaving, timesaving nasal feeding apparatus for the medical personnel that nursing loses the patient of swallow, only need suction tube is inserted in the dress liquid food vessel, discharge pipe is connected stomach tube, push rubber bag tank repeatedly and can finish the task of feeding, do not worry that with the nasal feeding of this product gastric enters air, and do not have the no refluence phenomenon of leakage.
Be described further below in conjunction with accompanying drawing.
The sequence number of marking is represented respectively among the figure: (1) rubber bag tank; (2) pump housing; (3) inspiration ball valve; (4) ring-type valve seat; (5) discharge ball valve; (6) valve seat of band crossbeam; (7) induction pipe; (8) inspiration extension pipe; (9) discharge pipe; (10) capsule is taken over; (11) inspiration valve chamber; (12) discharge valve chamber.
The valve seat (6) that ring-type valve seat (4) and band crossbeam are set is for the convenience on processing.The footpath should be less than inspiration ball valve (3) diameter within the ring-type valve seat (4), the two contact the time can be sealed passage, the valve seat (6) of band crossbeam also in the form of a ring, and with discharge ball valve (5) contact jaw one needle beam be set, keep certain clearance when making the two contact, and do not make the passage sealing.
When carrying out the nasal feeding operation, induction pipe (7) is inserted in the liquid food, as be that bottled medicinal liquor or liquid food can connect inspiration extension pipe (8).Push rubber bag tank (1) with hands, air is discharged, again stomach tube is linked to each other with discharge pipe (9), remove the pressure of hands subsequently to rubber bag tank (1), rubber bag tank is by elastic recovery, and valve body this moment air pressure interior and that rubber bag tank (1) is interior is lower than ambient atmosphere, and inspiration ball valve (3) is attracted to the crossbeam place that capsule is taken over (10) oral area, discharge ball valve (5) and be drawn to, through hole is sealed towards the through hole of inspiration valve chamber (11).Meanwhile liquid food is through ring-type valve seat (4), inspiration valve chamber (11) and wash inspiration ball valve (3) and capsule open and take over the gap of (10) and enter capsule and take in (10) and the rubber bag tank (1).Push rubber bag tank (1) this moment once more, inspiration ball valve (3) is pushed to ring-type valve seat (4) and passage is sealed, discharge ball valve (5) simultaneously and be pushed to the valve seat (6) of being with crossbeam, liquid food flow to be discharged valve chamber (12) and is washed the gap of discharging between ball valve (5) and the valve seat of being with crossbeam open through inspiration valve chamber (11), flows to stomach tube through discharge pipe (9) and enters human body.At this moment can push rubber bag tank (1) again, suck liquid food, push rubber bag tank (1) liquid food again and enter stomach tube, carry out so repeatedly, finish to nasal feeding.
Discharge pipe is connected flexible pipe, and the flexible pipe other end inserts esophagus and can be used to gastric lavage, and the other end inserts anus and can be used to coloclysis, and its operational approach is the same with the nasal feeding operation.
Claims (4)
