Description
Technical field
The utility model belongs to medical equipment technical field, and in particular to a kind of Nasal gastrointestinal tube connector.
Background technique
Nasal gastrointestinal tube is perfused for gastrointestinal decompression or enteral nutrition, and via intranasal application is inserted into patient's stomach or in enteron aisle, nose stomach
The conduit that intestinal tube generally comprises connector and is connected to connector, traditional Nasal gastrointestinal tube connector design only one cavity,
There is no side chamber.Lid would generally be provided on Nasal gastrointestinal tube connector, medical staff needs often to uncap or close lid, than
It is cumbersome.In addition, the connector of gastrointestinal nutrition tube is easy to be worn during frequently insertion syringe or negative pressure device,
It needs to change entire gastrointestinal nutrition pipe connector.
Summary of the invention
A kind of Nasal gastrointestinal tube connector provided by the utility model, for solving problems of the prior art.
In order to achieve the above object, the utility model uses following technical scheme:
Nasal gastrointestinal tube connector, it is described including main connection and at least one secondary connector being connected with main connection
Main connection and secondary connector include hollow ontology, and the ontology is equipped with the cavity of perforation or more, the pair connector
Lower part or bottom are connected with the body lower part of the main connection；It is arranged in the main connection and secondary connector compatible
Inner core is symmetrically installed with deck on the inner core inner cavity, and the top movable of the deck is equipped with shaft, and the shaft is far from card
The side of seat is connected with flow-guiding mouth, and one end of the flow-guiding mouth is connect with deflecting section, and the other end is connected with spring, and flow-guiding mouth is logical
It crosses deflecting section and clamping block is rotatablely connected, cavity wall is clamped in the clamping block and inner core.
It is respectively arranged with lug on the main connection and secondary connector two sides, fluted, institute is set on the lug
It states inner core both sides and is provided with card, for fixing inner core, prevent inner core from sliding.
The flow-guiding mouth material is silica gel, polyurethane or other macromolecules, when no liquid passes through, described two water conservancy diversion
Mouth portion forms closure V-type.
The outer diameter of the inner core is interference fit with the internal diameter of the main connection and secondary connector, prevents nutrient solution from entering
The main connection and secondary connector in the gap of corresponding inner core.
The inner core is made of rigid plastics.
The end of slide plate there are two symmetrically setting on the inner core inner cavity, the slide plate and flow-guiding mouth is slidably connected.
The utility model bring technical effect, by being arranged inner core inside connector, connector and inner core form a kind of work
Dynamic connection type, inner core are conveniently replaceable, and inner core inner cavity setting deck, shaft, flow-guiding mouth, spring, deflecting section, clamping block etc.,
When injecting liquid, flow-guiding mouth opens under the action of spring and deflecting section, when no liquid passes through, the flow-guiding mouth of two sides
The V-type for forming closure plays the role of closing connector, and liquid countercurrent can be effectively prevented.Reduce medical personnel located behaviour
Make, there is good application value.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram of the utility model inner core.
Specific embodiment
The utility model is further described with reference to the accompanying drawing.
Nasal gastrointestinal tube connector as Figure 1-Figure 2, including main connection 1 and at least one be connected with main connection 1
Logical secondary connector 2, the main connection 1 and secondary connector 2 include hollow ontology, and the ontology is equipped with perforation or more
Cavity, the lower part or bottom of the pair connector 2 are connected with the body lower part of the main connection 1；The main connection 1 and pair
Compatible inner core 3 is arranged in connector 2, the inner core 3 is made of rigid plastics.It is symmetrically installed on 3 inner cavity of inner core
There is deck 6, the top movable of the deck 6 is equipped with shaft 7, and the shaft 7 is connected with flow-guiding mouth 5 far from the side of deck 6,
The flow-guiding mouth 5 of two sides forms the V-type of closure.One end of the flow-guiding mouth 5 is connect with deflecting section 10, and the other end is connected with bullet
Spring 9, and flow-guiding mouth 5 is rotatablely connected by deflecting section 10 and clamping block 8, the clamping block 8 is clamped with cavity wall in inner core 3.Institute
Stating 5 material of flow-guiding mouth is preferably silica gel, polyurethane or other high molecular materials.When no liquid passes through, two water conservancy diversion
5 head of mouth forms closure V-type.
Two slide plates 11 are symmetrically arranged on 3 inner cavity of inner core, the end of the slide plate 11 and flow-guiding mouth 5 is slidably connected.
It prevents liquid from entering in the gap between flow-guiding mouth 5 and inner core 3, causes to adhere to liquid on spring 9, time long hair apt to deteriorate
It is smelly, it pollutes.
The main connection 1 and secondary connector are respectively arranged with lug 4 on 2 two sides, are provided on the lug 4 recessed
Slot, 3 both sides of inner core are provided with card 12, for fixing inner core 3, prevent inner core 3 from sliding.
The outer diameter of the inner core 3 is interference fit with the internal diameter of the main connection 1 and secondary connector 2, prevents nutrient solution
Into the main connection 1 and secondary connector 2 in the gap of corresponding inner core 3.
The utility model preferred embodiment is described in detail above, to those skilled in the art
