Detailed description of the invention
Embodiment 1:
As in Fig. 1 ~ 5, be convenient to the nasal feeding tube changed, the body 1 of nasal feeding tube, when not using, forms multiple alar part 101 by shrinkage, alar part 101 is reversed and is bonded together by binding agent 102, is less than body 1 internal diameter in use to make the external diameter of body 1 when not using.Structure thus, is convenient to the nasal feeding tube of body when not using 1 through former indwelling, thus is convenient for changing, when the external diameter of this utility model middle tube body 1 when not using is only use internal diameter 1/2 ~ 1/4.The material of body 1 adopts silica gel, PE polyethylene, PVC polrvinyl chloride, HDPE ultra high molecular polyethylene or TPE High performance polyolefin thermoplastic elastomer material, to improve decay resistance and intensity.The wall thickness of body 1 is at 0.05mm ~ 0.3mm.Binding agent 102 in this example adopts the compositions of starch, gelatin or starch and gelatin as binding agent.
Preferred scheme is as in Fig. 3, and body 1 is not when using, and at least one end of body 1 is coated with capsule protective sleeve 5, and capsule protective sleeve 5 is bonding with body 1 outer wall by binding agent.Structure thus, capsule protective sleeve 5 is conducive to body is tightened, and to improve through performance, capsule protective sleeve 5 adopts gelatin material, can digestedly absorb.
Preferred scheme is as in Fig. 2,5, and the inwall of body 1 is provided with thread eye 103.Structure thus, is convenient to built-in seal wire 4, to increase the flexibility of body 1 when not using.Seal wire in this example is because without the need to the guide structure as poling, therefore relatively low for performance requirement, can reduce costs.
As shown in Figure 9, in use, one end of body 1 is connected with adaptor 2.Structure thus, so that body 1 connects other auxiliary facilities.
Preferred scheme as shown in Figure 10, in described adaptor 2, in joint, the outer wall of siphunculus 23 is provided with external thread section 231 and male-tapered section 232, in joint, siphunculus 23 is connected with joint upper shell 22 and joint lower shell 24 by external thread section 231, joint lower shell 24 is provided with inner conical section 241, being pressed between male-tapered section 232 and inner conical section 241 of body 1.Structure thus, makes flexible body 1 reliably be connected with between adaptor 2.
As shown in Figure 9, described adaptor 2 is connected with liquid extruding device 9 preferred scheme, is provided with screw thread at the outer wall of adaptor 2, is tightly connected by the cylindrical shell 91 of screw thread and liquid extruding device 9;
In liquid extruding device 9, be provided with piston 92 in cylindrical shell 91, the sidewall of cylindrical shell 91 near bottom is provided with inlet 94, is provided with the first check valve 93 opened in cylindrical shell 91 in inlet 94;
Be provided with in the bottom of cylindrical shell 91 or adaptor 2 towards outer the second check valve 21 opened of cylindrical shell 91.Being arranged on by second check valve 21 in adaptor 2 to avoid nutritional solution to flow backwards.By push-and-pull piston 92, body 1 slowly struts by the nutritional solution with pressure, thus makes body 1 enter normal operating condition.Be specially, when pull-up piston 92, first check valve 93 is opened, the second check valve 21 is closed, and now nutritional solution enters in cylindrical shell 91 from inlet 94, and pressure piston 92, first check valve 93 is closed, and the second check valve 21 is opened, and nutritional solution enters in body 1.
Be through hole bottom body 1, bottom body 1, sidewall is provided with multiple side opening 3.Structure thus, avoids the bottom of body blocked.
Embodiment 2:
On the basis of embodiment 1, a kind ofly adopt the above-mentioned replacing options being convenient to the nasal feeding tube changed, comprise the following steps:
One, as shown in Figure 8, the body 1 under collapsed condition is penetrated the nasal feeding tube of former indwelling, arrive precalculated position;
Two, the nasal feeding tube of former indwelling is taken out along body 1; Preferably in the nasal feeding tube process of taking out former indwelling, the nasal feeding tube segmentation of former indwelling is cut, taken out.Due to body 1 is in collapsed condition when not using under, alar part 101 tightens coated, therefore internal diameter is less, clutch former indwelling tube, untapped body 1 is made to be close to the inwall of former indwelling tube, easily former indwelling tube can be cut off, thus segmentation is taken out, and is taken out of by body 1 in taking-up process to avoid former indwelling tube.
The replacing of nasal feeding tube is realized by above step.
During use as shown in Figure 9; body 1 is connected with adaptor 2; adaptor 2 is connected with liquid extruding device 9; the piston 92 of push-and-pull liquid extruding device 9 pushes nutritional solution; make that body 1 is swelling enters using state, when nutritional solution arrives the bottom of body 1, under the thrust of nutritional solution; capsule protective sleeve 5 departs from from the bottom of body 1, nutritional solution is sent into the gastrointestinal portion of patient.Capsule protective sleeve 5 is absorbed by pipe intestinal digesting after being softened by nutritional solution.
The above embodiments are only optimal technical scheme of the present utility model, and should not be considered as restriction of the present utility model, the every technical characteristic described in this utility model, under the prerequisite of not conflicting mutually, can combine mutually, and be not limited only to the description in embodiment.The technical scheme that protection domain of the present utility model should be recorded with claim, the equivalents comprising technical characteristic in the technical scheme of claim record is protection domain.Namely the equivalent replacement within the scope of this improves, also within protection domain of the present utility model.
