Abstract

The utility model relates to a multi-passage venous transfusion device for infants, which is composed of a stainless steel needle core and a flexible sleeve pipe, wherein the surface of the needle core is smooth, the tip of the needle core is sharp, and the tail end of the needle core is provided with a base; the front end of the sleeve pipe is provided with a puncture sleeve pipe, and the tail end is connected with a main connecting pipe and a side connecting pipe; a diaphragm is arranged at the interface point of each of the connecting pipes. When the utility model is used, the needle core which penetrates through the diaphragm is integrated with the sleeve pipe into a whole, and punctures into a blood vessel; the needle core is pulled out, the sleeve pipe is fixed and a transfusion pipe is communicated. The utility model can be continuously used for many times after once puncture, and can be simultaneously injected with other medicines from the side connecting pipe. The utility model is convenient for first aid.

Description

Multichannel children's intravenous transfusion device

This utility model belongs to medical apparatus and instruments, relates to the multichannel transfusion device that a kind of children's intravenous transfusion is used.

Clinically, giving infant venous transfusion (be commonly called as and beat transfusion bottle), is department of pediatrics treatment means commonly used, generally takes 3～7 days each course of treatment.Because children's's blood vessel is thinner, most children's are more fat again, peripheral vessels exposes not obvious, children's is ignorant of cooperating in addition, venipuncture is difficulty very, not at all easy sometimes the puncture successfully, and infant one is cry and screamed to touch to tend to make put and is stayed endovascular hard syringe needle and wear out blood vessel, liquid and vessel inner blood drain to EV subcutaneous tissue, cause local hematoma.Chance contains the necrosis that the stronger medicine of zest also causes local organization easily.For the ease of fixing, department of pediatrics nurse's more options head blood vessel is a point of puncture, and every puncture once needs the local hair of infant is shaved off a slice, and the infant hair remains little after several days, and what stay is the pinprick of many places, has increased the infection chance and the head of a familys' psychological burden.

For solving an above-mentioned difficult problem, this utility model purpose is to design the multichannel children's intravenous transfusion device that a kind of one-time puncture can continuous several times uses, and can also carry out the other medicines injection in transfusion.Thereby alleviate the misery of infant and medical personnel's work load.

Structure of the present utility model is made up of nook closing member and sleeve pipe two parts as shown in drawings.Nook closing member 1 is the length 10～20cm that is made by stainless steel material, the fine needle of diameter 0.1～0.5mm, smooth surface, and needle point is sharp keen.The nook closing member end has a base 6.Can be made into the model that varies in size as required.

Sleeve pipe partly is a hollow pipe of being made long 9～18cm by medical grade silicon rubber or other medical gentle material, comprises puncture casing 2, main adapter 3 and side joint pipe 4.Puncture casing 2 is the big hollow hoses of a good toughness elasticity, and external diameter is 0.11～0.55mm, internal diameter 0.1～0.5mm (adapting with supporting nook closing member), the mouth of pipe (needle tip) wall is thin and sharp, and its good springiness closely connects together with nook closing member in addition, form an inclined-plane, unlikely generation resistance during puncture.Main to take over 3 be the extendible portion of puncture casing 2, is provided with diaphragm 5 in its interface, will lead the adapter chamber and be divided into two sections, and the film inner chamber communicates with the puncture casing chamber, and film external tapping and nook closing member base are complementary, and adapt with the connector portions of tube for transfusion.The double-layer circular thin film that barrier film 5 is made by silica gel or other medical flexible material, the internal layer of film (one side that communicates with 2) contain anti-blood coagulation material.Side joint pipe 4 structures are taken over main, are provided with in the interface with main the adapter and go up same barrier film, and tube chamber communicates with the puncture casing chamber in the film, and the film external tapping is suitable for mutually with tube for transfusion or syringe adapter.

When this utility model uses, at first choose suitable model, the barrier film and the sleeve pipe part suit that supporting nook closing member are passed main adapter are one, behind the routine disinfection, the needle tubing that will puncture penetrates in the blood vessel with nook closing member, push down the puncture casing of internal blood vessel then gently with finger, in addition hand-held nook closing member base is slowly dialled except that nook closing member; Then the needle section (should select the hour hand head) of tube for transfusion is passed barrier film and make the interface embedding of tube for transfusion joint and adapter tight, can give patient infusion.The same day, transfusion finished, and tube for transfusion is pulled out from the interface portion of taking over.Sleeve pipe partly continues to keep, and connects tube for transfusion next day again and just can continue transfusion.During the transfusion, need to inject other drug to infant simultaneously, can inject through side joint pipe 4.

This utility model reaches purpose of design fully through on probation, can use continuously 5～7 days through one-time puncture.Do not influence the infant limb activity during the transfusion, and help the rescue that critical illness is gone into.
