Abstract
To solve the deficiencies in the prior art, the utility model provides a kind of nose catheter, including body, shutoff valve is provided with one end of body, and shutoff valve is normally closed.Furtherly, the other end of shutoff valve is connected with the injection port of syringe.Beneficial technique effect：When in use, it is to open to keep valve to the utility model；Injection is finished, and to prevent gastric juice reflux from being damaged to patient, 90 ° of shutoff valve of rotation can close valve, remove a hidden danger.Can be that the nursing of stomach tube be provided convenience using the utility model, additionally, improve the security of putting pipe, while also improving the comfort level of patient's indwelling nose catheter, promote patient's quick recovery.
Description
Technical field
The utility model belongs to technical field of medical equipment, and in particular to a kind of nose catheter.
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. negative pressure disk separates reconnection with stomach tube repeatedly when toppling over gastric juice, 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.
Therefore, in order to preferably using nose catheter and simplification nursery work, it is necessary to be carried out in structure to current stomach tube
Improve.
Utility model content
To solve the deficiency in the presence of background technology, the utility model uses following technical scheme：
A kind of nose catheter, including body 1, shutoff valve 2 is provided with one end of body 1, and shutoff valve 2 is normally closed, and is bipass.
Furtherly, the other end of shutoff valve 2 is connected with the injection port of syringe 3.
Beneficial technique effect
When use/injection, it is to open to keep valve to the utility model.Injection is finished, to prevent gastric juice reflux
Patient is damaged, 90 ° of shutoff valve of rotation can close valve, remove a hidden danger.
Can be that the nursing of stomach tube be provided convenience using the utility model, additionally, the security of putting pipe is being improve, together
When also improve the comfort level of patient's indwelling nose catheter, promote patient's quick recovery.It is in particular in：
1. gastric juice is not resulted in backflow.
2. the probability of pollution is reduced.
3. while omitting silica gel pipe close, gastric juice leakage is not resulted in, bedding and clothing will not be polluted, and ensure pipe sealing,
And then avoid retrograde infection.
4. remove nurse from complete to need reflexed stomach pipe end again with the work of gauze wrapped after nasal feeding medicine, food terminate
Make, so that nursery work becomes succinct, reduce workload.
Brief description of the drawings
Fig. 1 is schematic perspective view of the present utility model.
Fig. 2 is the schematic perspective view of shutoff valve 2 in Fig. 1.
Specific embodiment
Design feature of the present utility model is described in detail in conjunction with accompanying drawing.
Referring to Fig. 1, a kind of nose catheter, including body 1, shutoff valve 2 is provided with one end of body 1, shutoff valve 2 is normally closed, and
It is bipass.
Referring to Fig. 1, furtherly, body 1 is the big tapered hollow pipe in the small one end in one end.The body 1 of the big side in section
End is connected with one end of shutoff valve 2.
Referring to Fig. 2, furtherly, the port of the shutoff valve 2 of the side that is connected with body 1 is taper joint.
Furtherly, it is being provided with rubber garter spring 4 on the body 1 of the side of shutoff valve 2.By rubber garter spring 4 by body 1
It is fixed together with shutoff valve 2.
Referring to Fig. 1, furtherly, the other end of shutoff valve 2 is connected with the injection port of syringe 3.
Furtherly, the injection port in syringe 3 is provided with internal thread.Be connected with syringe 3 side shutoff valve 2 end
Mouth is provided with external screw thread.By way of screw thread, syringe 3 is removably joined together with shutoff valve 2.
Referring to Fig. 2, furtherly, the port of the shutoff valve 2 of the side that is connected with body 1 is Rule female joint.
Furtherly, syringe 3 includes shaft and the part of push rod 2.Projection piece is provided with the end of shaft.Set on push rod
There is projection piece.Spring 5 is provided between the projection piece of shaft and the projection piece of push rod.When shutoff valve 2 is opened, syringe 3 is passed through
Shutoff valve 2, body 1 are communicated with patient's body, by the relative motion between push rod and the body of rod, realize pressure release.
Furtherly, the material of the valve body of shutoff valve 2 and valve element is all PP (polypropylene).The shutoff valve 2 of PP materials is acidproof,
The resistance to most of organic solvents of alkali, salt, alcohol, phenol, aldehyde, ketone, comply fully with the requirement of general medical medical equipment.
Furtherly, the material of body 1 is silica gel.The body 1 of silica gel material and the taper joint interference fit of shutoff valve 2
Afterwards, because silica gel has elasticity and sealing well, by the fully wrapped around sealing of cone-shaped interface, and corresponding frictional force can be produced
Prevent from coming off.
