Description
Technical field
The utility model is related to medical equipment technical field, specifically a kind of venous detaining needle.
Background technology
At present, venous detaining needle is widely used in clinical transfusion, needle stand, extension tube and calparine cap is passed through medical transparent
Pad pasting is fixed on sufferer skin, can be made to be retained in the soft pin in sufferer vein blood vessel and is administered continuously, the application of remaining needle can subtract
Few injury of vein, protects blood vessel, reduces the difficulty of follow-up puncture, alleviates the pain that long-term infusion patient punctures repeatedly, improves
The satisfaction of sufferer and family members, and it is effectively reduced the workload of nurse.
Because the time that remaining needle is fixed on sufferer skin is longer, generally 72 to 96 hours, and need to be fixedly secured, prevent
Anti-avulsion pin, and the needle stand and calparine cap of remaining needle of the prior art are cylinder, the contact area with sufferer skin is smaller,
Along with the contention effect of medical transparent pad pasting, larger pressure can be produced to patient skin, in needle stand and calparine cap end position
Put, can produce larger shearing force to skin, and above-mentioned pressure and shearing force are continuously applied, the exactly clinically generation of pressure sore
Condition, for hydroderma, subcutaneous fat content is less, and point of puncture is then particularly susceptible close to joint part or children's sufferer
Pressure sore is produced, the pain of sufferer is added.Due to remaining needle when in use, the relative position of its needle stand and calparine cap and apart from simultaneously
Do not fix, and the extension length of tube in traditional remaining needle is non-adjustable whole, generally requires not advise with sufferer skin using multiple tracks adhesive tape
Then fix, but fixed effect is unsatisfactory, it is easy to and bending gives a discount, and blocks and is administered continuously, and influences therapeutic effect.
Utility model content
The utility model, which is aimed to provide, a kind of is not likely to produce pressure sore and the venous detaining needle of the not flexible discounting of extension tube.
In order to solve the above technical problems, a kind of venous detaining needle of the present utility model takes following technical scheme：It is a kind of
Venous detaining needle, including needle stand, be fixed on needle stand one end and by be retained in the soft pin being administered continuously in sufferer vein blood vessel with
And the extension tube on needle stand is connected to, one end of extension tube is by needle stand and Ruan Zhen UNICOMs, and the other end, which is connected with, to be used for indwelling
The calparine cap of pin tube sealing, the needle stand and calparine cap are fixed on the skin of sufferer by medical transparent pad pasting respectively, the pin
Seat and calparine cap be semi-cylindrical, needle stand and calparine cap are pressed close to by its flat sidewall with sufferer skin respectively, the needle stand
Flat sidewall and needle stand circular arc surface side wall between, between the flat sidewall of the end of needle stand and needle stand and needle stand end
Arc surface transition, the flat sidewall of the calparine cap and the circular arc surface side of calparine cap are used between the circular arc surface side wall of needle stand
Between wall, between the flat sidewall of the end of calparine cap and calparine cap and calparine cap end and the circular arc surface side wall of calparine cap
Between use arc surface transition；Pressure sore prevention dressing is provided with the flat sidewall of the needle stand and calparine cap, it is described against pressure
The surface of sore dressing is pasted with sterility protection film；Being set in the middle part of the extension tube can be according between needle stand and calparine cap
Fixed range arbitrarily flexible helical spring shape.
It is preferred that, it is provided with the circular arc surface side wall of the needle stand and calparine cap for strengthening and the medical transparent dressing
The adhesive sticker that film is fixed.
It is preferred that, the extension tube is connected on the circular arc surface side wall of needle stand close to the position of the flat sidewall of needle stand, institute
State soft pin and be fixed on needle stand one end close to the position of needle stand flat sidewall.
It is preferred that, the pressure sore prevention dressing is bearing hydrocolloid dressing.
Beneficial effect
Needle stand and calparine cap of the present utility model are disposed as semicylinder, by increasing the contact area with sufferer skin
The pressure suffered by local skin is effectively reduced, while the flat sidewall of semicylinder and circular arc side wall and the end wall at two ends
Between angle be disposed as the chamfering of circular arc, the needle stand and calparine cap of traditional remaining needle are eliminated using arc-shaped transitional surface
The shearing force produced to skin, and pressure sore prevention dressing is provided with the wall of surface side, so as to greatly reduce the several of pressure sore generation
Rate.It is set to according to the arbitrarily flexible helical spring shape of the fixed range between needle stand and calparine cap to be begun in the middle part of extension tube
Tensioned state is kept eventually, is effectively avoided the extension tube continued administration that causes of bending that gives a discount and is obstructed.
