Use the patient of enteral nutrition more general clinically, special in Cavity in Critical Patients, need especially to implement enteral nutrition, at present, nutrition infusion device be adopt to be provided with the infusion device of nutrition bottle connection cover, connection cover is utilized to be connected with nutrition bottle bottleneck spiral, the sealed membrane of needle pierces bottleneck, as the patent No. Chinese utility model patent that is CN203208383 a kind of enteral nutrition infusion device disclosed in the JIUYUE in 2013 25 days, be provided with the feeding solution connection cover be connected with feeding solution exit, Elental is facilitated to enter silica gel tube from feeding solution connection cover, solidifying and blocking of nutritional solution can be effectively reduced, carry the infusion velocity of nutritional solution.But the nutrition on market also bottle is all not the structure adopting screw lid, also has some to be adopt the serum cap being similar to ampere bottle cap, open inconvenience with this infusion device.
Utility model content
The disposable enteral nutrition infusion device supplying the feeding solution of screw lid or serum cap dual-purpose after the purpose of this utility model is to provide a kind of improvement, more practical, scope of application liquid is wider, and it is convenient to insert.
In order to achieve the above object, this utility model adopts following technical scheme: the modified node method of disposable enteral nutrition infusion device, comprise infusion body, along the link for connecting feeding solution that described infusion body sets gradually, dropper section, three way cock's parts, nasogastric tube joint component, described link is connected by hard siphunculus with described dropper section, described hard siphunculus is provided with external thread section, described link comprises and seals with the external spiral section of described hard siphunculus the hermetically-sealed construction surrounding and be connected, by described hard siphunculus extend and the extension be located in described hermetically-sealed construction, be enclosed in described hard siphunculus outer and be limited in described hard siphunculus and the screw lid moved between described hermetically-sealed construction and the piercing needle be connected with described extension, the screw thread of described screw lid and the external screw thread of described external thread section suitable.
As preferably, described hermetically-sealed construction comprises the flexible tube section be connected with described external spiral section and the sealing ring be connected with described flexible tube section, the centre bore that described sealing ring intermediate formation passes through for described piercing needle.
As preferably, described screw lid comprises the spire of leading portion and the sealing after being positioned at described spire, and the inner surface of described sealing is provided with sealant.
As preferably, hard siphunculus extends to the periphery of described hard siphunculus and adds coarse-texture, adds in coarse-texture described in described external spiral section is arranged on.
As preferably, described piercing needle exceeds the upper surface of described sealing ring.
As preferably, described hard siphunculus extends in described dropper section downwards, forms dropping liquid section.
As preferably, described hermetically-sealed construction is silica gel sealing structure, and sealing effectiveness is better.
As preferably, described piercing needle is metal puncture syringe needle, effective to the puncture of rubber bottle cap, more laborsaving.
By implementing technique scheme, the structure that this utility model improves is simple, practical, and the feeding solution that simultaneously can be applicable to screw lid or serum cap uses, and the scope of application is wider.
