As shown in fig. 1 to 7, the nasal feeding device comprises a barrel 10, a rod 20, an enclosing member, an elastic sealing member and a conduit 40, wherein the enclosing member is a U-shaped silica gel sleeve 30, the elastic sealing member is a piston 204, the piston 204 is sleeved on the rod 20, the barrel 10 can be communicated with the conduit 40, and the conduit 40 is communicated with the stomach. The cylinder 10 comprises a first section 101 and a second section 102, wherein the inner diameter of the second section 102 is smaller than that of the first section 101, and the axial length of the second section 102 is smaller than that of the first section 101. The first section 101 and the second section 102 are in smooth transition, and the formed transition area is the second limiting part 103. An annular protrusion 104 is provided on the outer surface of the first segment 101, and the annular protrusion 104 protrudes on the first segment 101 along the circumferential direction.

As shown in FIG. 6, the inner diameter of the second section 102 of the barrel 10 is smaller than the inner diameter of the first section 101, and the axial length of the second section 102 is smaller than the axial length of the first section 101. the inner diameter of the barrel 10 is configured to facilitate the aspiration/injection of the liquid food from the second section 102 of the barrel 10: the rod body 20 extends into the first section 101 until being limited by the second limiting part 103, and cannot extend continuously, then the second section 102 extends into the liquid level of the liquid food, the rod body 20 is pulled out of the cylinder body 10, at the moment, negative pressure is generated in the cylinder body 10, and the liquid food enters the cylinder body 10 under the action of atmospheric pressure; after the barrel 10 is filled with the liquid food, the second section 102 is fixed with the conduit 40, the other end of the conduit 40 is communicated with the stomach from the nose, the rod body 20 is held by hand, and the liquid food is injected by pushing the liquid food out of the second section 102, enters the conduit 40 and flows into the stomach. In the process, as the inner diameter of the second section 102 is smaller than that of the first section 101, the section is smaller, so that the pressure is increased, the pressure and the flow rate of the liquid food flowing out of the second section 102 are both higher, the liquid food is injected into the stomach quickly, and the nasal feeding time is shortened.

As shown in fig. 1, the annular protrusion 104 on the outer surface of the first section 101 facilitates the finger to grasp the barrel 10, the barrel 10 and the shaft 20 need to move axially relative to each other during the process of injecting the liquid food, and the annular protrusion 104 facilitates the application of force to the barrel 10.

As shown in fig. 2, the rod body 20 includes a stress section 201 and a holding section 202, the barrel 10 is sleeved on the stress section 201, the axial length of the rod body 20 is greater than the axial length of the first section 101, a first limiting portion 203 is arranged between the stress section 201 and the holding section 202, the first limiting portion 203 is limited to the barrel 10, a plurality of strip-shaped protruding portions are arranged on the surface of the holding section 202, and the strip-shaped protruding portions are axially arranged along the rod body 20. The end of the force-bearing section 201 is provided with a piston 204, and the piston 204 wraps the end of the force-bearing section 201.

The axial length of the shaft 20 is greater than the axial length of the first section 101 to ensure that there is an excess portion of the shaft 20 as a gripping section 202. The first limiting part 203 is used for limiting the palm: when liquid food is injected, the palm grasps the holding section 202 and needs to push the barrel body 10 with large force, the palm tends to slide towards the stress section 201, and the first limiting part 203 limits the tendency; the strip-shaped protruding part reduces the contact area between the palm and the holding section 202, increases the pressure between the palm and the holding section 202, and the first limiting part 203 and the strip-shaped protruding part are used for ensuring that the palm always grips the holding section 202.

The piston 204 is fixed at the tip of atress section 201, and when atress section 201 got into first section 101 in, the inseparable friction of piston 204 circumferential surface and first section 101 inner wall guaranteed that atress section 201 slides in first section 101, the gas tightness of piston 204 both sides, just can guarantee barrel 10 internal pressure when barrel 10 absorbs/pushes the liquid food like this, realizes the nasal feeding process.

The first section 101 is matched with the force-bearing section 201, and the inner diameter of the first section 101 is corresponding to the outer diameter of the force-bearing section 201. The rod body 20 can be inserted into the barrel body 10 to be placed, the rod body and the barrel body can also be placed respectively, and the inner diameter of the first section 101 is slightly larger than the outer diameter of the stress section 201. The axial length of the holding section 202 is 10 cm, the axial length of the stress section 201 is 15 cm, and the length of the cylinder 10 is 17 cm.

As shown in fig. 3 and 4, the U-shaped silica gel sleeve 30 includes a main body, an inclusion region 301, a fixing portion 302, and an air hole 303 are disposed on the main body, the inclusion region 301 is inside the U-shaped silica gel sleeve 30, the fixing portion 302 is an opening of the U-shaped silica gel sleeve 30, and the air hole 303 is located at the bottom of the U-shaped silica gel sleeve 30. The enclosing region 301 is enclosed in the circumferential direction of the holding section 202, the air hole 303 corresponds to the end of the holding section 202, and the fixing portion 302 is fixed on the first limiting portion 203.

The fixing parts 302 are all fixed on the first limiting part 203, when the palm of the medical staff grasps the holding section 202, the palm contacts the U-shaped silica gel sleeve 30 firstly, then the palm continues to be folded, the air holes 303 can exhaust air in the U-shaped silica gel sleeve 30, so that the U-shaped silica gel sleeve 30 can be tightly pressed on the holding section 202, and when the palm pushes liquid food to exert force, the pressure between the palm and the holding section 202 can be buffered because the U-shaped silica gel sleeve 30 has elasticity; and U type silica gel cover 30 has increased the area of contact of palm and the section 202 of gripping, has reduced pressure, and the palm feels comfortable, grips for a long time and also can adapt to, protects medical personnel's palm.

The above embodiments are intended to be illustrative, and should not be construed as limiting the scope of the invention, and the technical solutions, objects and effects of the present invention are described in full herein.

The above examples are not intended to be exhaustive list of the present invention, and there may be many other embodiments not listed. Any replacement and improvement made on the basis of not violating the conception of the utility model belong to the protection scope of the utility model.
