Description
Technical field
The utility model belongs to technical field of medical instruments, more particularly to medical postoperative care apparatus, specially a kind of
Nose catheter combined apparatus.
Background technology
Nose catheter is extensive in clinical many section office even community, family because patient's state of an illness needs as a kind of medical treatment consumptive materials
Using, such as it is used for gastrointestinal decompression, or by pipeline feeding food, medicine etc..Therefore nursing staff is for the shield of indwelling nose catheter
Reason is particularly important.The nose catheter of current Clinical practice is a transparent silicon sebific duct, and front end is cecum, there is side opening, is placed in stomach
Interior, distal opening can connect the drainage systems such as negative pressure disk or connection syringe and carry out nasal feeding medicine, food etc., have by distal opening
One silica gel pipe close, during without negative pressure and nasal feeding, directly clogs stomach tube distal opening, plays a part of to close stomach tube.
During Canal Nursing, nursing staff has found that current nose catheter has the following disadvantages：
1. easily cause gastric juice to backflow, liquids and gases in inconvenience band pipe discharge negative pressure disk.
2. need to separate stomach tube with negative pressure disk when toppling over gastric juice, reconnected after toppling over, increased the probability of pollution.
3. nose catheter distal opening and silica gel pipe close Reusability for several times, or during nasal feeding finish medicine, under degree of being completely embedded
Drop, it is easy to slip, cause gastric juice to leak outside, retrograde infection is also easily caused while pollution bedding and clothing because pipeline is opened.
4. to avoid above-mentioned situation, it is necessary to reflexed stomach pipe end is again with gauze wrapped after nurse's nasal feeding medicine, food terminate,
So that nursery work becomes cumbersome, workload is increased.
Utility model content
For the above-mentioned deficiency of existing nose catheter, the utility model provides a kind of nose catheter combined apparatus, and concrete structure is such as
Under：
A kind of nose catheter combined apparatus, are made up of screw syringe 1, shutoff valve 2 and stomach tube assembly.The injection of syringe 1
Mouth is connected through shutoff valve 2 with one end of stomach tube assembly.
The stomach tube assembly is made up of flexible pipe 4, infusion regulator 5, hard tube 6 and external screw joint 7.Wherein, in flexible pipe 4
Infusion regulator 5 is cased with pipe shaft.One end of flexible pipe 4 is connected with one end of hard tube 6.The other end of hard tube 6 connects with external screw thread
Mouth 7 is connected.The external screw joint 7 is used to be connected with shutoff valve 2.
Beneficial technique effect
The increased infusion regulator 5 of the utility model and shutoff valve 2, possess 2 grades of functions of closure, and dual guarantee ensures this
The conducting and cut-off of utility model.
By infusion regulator 5, the uninterrupted of drainage-fluid can be controlled.This is the work(not available for conventional nose catheter
Energy.
The infusion regulator 5 that the utility model is used is the standard component on woven hose, and buying is convenient, with low cost.This reality
With the component parts of the shutoff valve 2 of new use, standardized element is, purchase cost is low.
Infusion regulator 5 in the utility model can be moved up and down and fixed along flexible pipe 4, convenient to confirm and mark flexible pipe
4 insertion depth, very intuitively, it is easy to medical personnel's observation judgement, also improves the comfort level of user.
After using the utility model, when gastric juice is toppled over, as long as close infusion regulator 5 just can directly discharge gas,
Liquid.Avoid under the conditions of existing structure, it is necessary to stomach tube and negative pressure disk are separated and toppled over again, or caused by avoiding extruding negative pressure disk
Gastric juice and gas backflow, so as to the danger for avoiding pollution, retrograde infection even suffocates.
After using the utility model, after tube feed food, medicine, without nursery works such as reflexed stomach tube, gauze wrappeds, only
Need to close infusion regulator 5 and/or shutoff valve 2, be that Canal Nursing is provided convenience, more reduce leakage and pollution,
The comfort level during patient puts pipe is increased, enthusiasm of the patient with pipe activity is improve.
In the utility model, screw syringe 1 is used with stomach tube assembly and is threadedly coupled with shutoff valve 2, shutoff valve 2：
The external screw joint 23 for constituting shutoff valve 2 is connected with screw syringe 1, constitutes the internal thread interface 24 of shutoff valve 2 and constitutes
The external screw joint 7 of stomach tube assembly is connected, it is ensured that be connected firmly be difficult to disconnect two-by-two, it is to avoid the problem of liquid leakage, really
Protect the possibility that is clean, reducing secondary pollution of sick bed.
