Description
Technical field
The present invention relates to field of medical products, specifically a kind of micro pump screw-type extension tube.
Background technology
Hospitals at Present uses cooperatively micro pump often in transfusion, effectively to control transfusion speed, maintains glucostasis, is facing
Need to use syringe extension tube in bed use, one end is connected on the syringe for being installed on micro pump, and the other end then connects puncture
With the needle tubing of patient's vein.Micro pump extension tube traditional first when in use, is inserted directly into syringe, therefore connection
Not closely, when pressure is slightly larger, liquid is easily flowed out outside pipe, causes the waste of liquid.Secondly traditional micro pump extension tube is more
When changing syringe, operator's left hand elder generation reflexed extension tube, coordinating with the right hand makes the female joint of extension tube and syringe adapter realization
Separate, reconnect syringe to be replaced, connecting tube upper end and mother when the purpose of reflexed is the syringe for avoiding connection to be replaced
Bubble is produced in joint, it is in a rush during operation to operating unskilled person, influence operating efficiency and nursing quality, reflexed to make
Extension tube torsional deformation, it is impossible to meet recycling.When traditional micro pump extension tube is infused again, typically using hot hair
Towel or hot-water bottle apply in extension tube to carry out medicine liquid heating, and firing rate is slow, the bad control of temperature, it is impossible to meet defeated for a long time
Liquid is heated during liquid.In a kind of drainage tube extension tube disclosed in the patent of Application No. CN201520053046.X
The junction of the extension tube and drainage tube connects by sealing ring, although this connection is very closely, when using not
Convenient dismounting.Based on this invention provides a kind of micro pump screw-type extension tube.
The content of the invention
In order to solve the above technical problems, the present invention provides a kind of micro pump screw-type extension tube.The extension tube has operation
Conveniently, safely, it is completely embedded, the characteristics of being heated to liquid.
The technical solution adopted by the present invention is：A kind of micro pump screw-type extension tube, including connecting tube, female joint and needle stand
Joint, female joint is connected by connecting tube with needle stand joint, and connecting tube is provided with screen pack, and described female joint is by Taper Pipe section
Constituted with column jecket section two parts, the column jecket section of female joint is connected by Taper Pipe section with connecting tube, the Taper Pipe section of the female joint
On be cased with taper, the osculum end diameter of the aperture more than the Taper Pipe section of female joint at the osculum end of taper, taper
Osculum end big opening end diameter of the aperture less than the Taper Pipe section of female joint, the aperture of the big opening end of taper is more than female joint
Taper Pipe section big opening end diameter, the inwall on taper positioned at big opening end side is provided with screw thread, and taper is located at small
Multiple annular protrusions are set on the inwall of mouth end side, and the central axis of annular protrusion is mutually overlapped with the central axis of taper
Close, the annular protrusion is made of elastomeric material, heating dress is installed in the connecting tube between screen pack and needle stand joint
Put.
Further, the diameter of female joint column jecket section is identical with the diameter at the osculum end of female joint Taper Pipe section.
Further, the Taper Pipe section of female joint is additionally provided with for controlling only pressing from both sides for liquid with the junction of connecting tube, described
Only folder include rotating handles, rotary shaft and catch, rotary shaft one end connection rotating handles, the other end connection of rotary shaft keeps off
Piece.
Further, one handle is also fixed with described taper outer wall.
Further, described heater temperature control is at 30 DEG C -35 DEG C.
Further, described heater is provided with controlling switch.
Further, described catch is circle, and catch is made of elastomeric material, the diameter and female joint Taper Pipe of catch
The diameter at the osculum end of section is identical.
Beneficial effect：
First, traditional micro pump extension tube when in use, is inserted directly into syringe, therefore connection is not tight, in pressure
Liquid is easily flowed out outside pipe when slightly larger.The micro pump screw-type extension tube of the design is provided with taper due to female joint, protects
The column jecket section for demonstrate,proving female joint is fully inserted into syringe, so as to avoid joint exposed to outside, reduces the chance of liquid infection.
The screw thread being provided with by taper inwall side, on the one hand can realize the tight connection with syringe, prevent liquid from outflowing,
Multiple annular protrusions are set on taper opposite side inwall and have further functioned as dual sealing functions；On the other hand connection or
Connection or dismounting that taper can complete with syringe, the female joint when taper is screwed need to be only screwed in unloading process
Whole connecting tube will not be driven to act, therefore will not make connecting tube torsional deformation in connection or in dismantling rotary course, can caused
Extension tube is able to repeatedly utilize.Taper causes that female joint and syringe, can not only by screwing taper in connection
The tight connection of sleeve pipe and syringe is realized, and sleeve pipe is tightr with female joint during screwing；
2nd, the only folder of female joint Taper Pipe section and the junction of connecting tube is first closed when syringe is changed every time, makes catch and company
Adapter is perpendicular, then screws taper, on the one hand avoids when syringe is changed air inlet in extension tube and causes blood
It is back in extension tube even syringe, so as to alleviate the pain of patient；On the other hand prevent other bacteriums to enter again to prolong
Long tube pollutes liquid.Only folder need to be only opened after replacing syringe can carry out normal infusion, more square using safer, operation
Just；
When the 3rd, being infused using traditional micro pump extension tube, typically using hot towel or hot-water bottle apply in extension tube come
Medicine liquid heating is carried out, firing rate is slow, the bad control of temperature, it is impossible to meet liquid is heated when infusing for a long time.This hair
The bright temperature that can be effectively controlled liquid by heater, one side liquid is input into patient's body again by heating, can reduce body
The consumption of interior heat energy, reduces liquid viscosity, reduces frictional force of the liquid to vascular wall；Another aspect heating-up temperature can for human body
Receive temperature, the composition in liquid will not be decomposed because temperature is too high；
4th, taper and syringe adapter are completed by the handle of rotation conic sleeve outer wall in connection or unloading process
Connection, so as to complete the connection or dismounting of extension tube and syringe, while be it also avoid because of rubber sleeve when syringe is changed
Can not smoothly dismantle, save the time, improve the operating efficiency of medical worker.
