Abstract

A fixing rack for a transfusion needle is characterized in that two parallelly-separated chassis (1) are connected with each other into a whole in a vertically bridging way by a portal rack (2) provided with a portal hole (3). Junctions among two inner walls of the portal hole (3) and the bottom surfaces of the chassis (1) are cambered surfaces (10). Pasting layers (4) are arranged on the bottom surfaces of the chassis (1). Protective paper (5) is attached outside the pasting layers (4). The head of the needle handle can be guaranteed to be smoothly and tightly clamped into the portal hole. The fixing rack is simple in structure and convenient in use and can well fix the needle in the transfusion process. The fixing rack can prevent needle from running in the transfusion process, and pains, swelling, repeated acupuncture, liquid medicine waste arising from the needle running, protects blood vessels of a patient and completely improves the transfusion conditions of the patient.

Description

The infusion needle fixed mount

Technical field

This utility model is used for fixing the infusion needle fixed mount of syringe needle when relating to a kind of the transfusion.

Background technology

When using disposable transfusion device to carry out venous transfusion, though the tube for transfusion front end that the adhesive tape fixed needle is arranged and be connected with syringe needle, fixing unreal because of syringe needle, the relative skin of needle handle fin is easy to generate slip; Or because of vein is crooked, when patient's limbs move once in a while, occur easily running pin (needle point stings out blood vessel), cause blood vessel injury, cause pain, swelling, heavily prick and liquid waste.

" the anti-moving frame of disposable use intravenous drip syringe needle " of the applicant's power of once patenting (ZL200920033387.5) can effectively solve the fixing of infusion needle and the pin problem is run in the prevention transfusion.How on the big basis of its structure, better adapt to all kinds of patients' transfusion requirement, make things convenient for transfusion operation, but it still has the development and perfection part.

Summary of the invention

This utility model is exactly the deficiency that exists in the above-mentioned prior art for solving, provide a kind of simple in structure, can be used with infusion needle, the infusion needle fixed mount of good fixing effect.

The technical solution of this utility model is:

This infusion needle fixed mount is that between two parallel isolating underframe, to be provided with a vertical cross-over connection of the portal in shape hole by one be one.The width in door shape hole should satisfy snapping in of needle handle head non-loosening and can limit the position of center line that infusion needle is positioned at two underframe intervals.

The further technical solution of this utility model is:

The intersection of door shape hole two inwalls and underframe bottom surface is a cambered surface.

The bottom surface of underframe is provided with adhered layer.

The adhered layer outside is with protection sheet.

This utility model advantage compared with prior art with progress is:

1, (ZL200920033387.5) compare with " the anti-moving frame of disposable use intravenous drip syringe needle ", underframe is a hatch frame, removes the connection bow member of " the anti-moving frame of disposable use intravenous drip syringe needle " end from; This can: the structure of simplifying injection mould; Economical with materials when doing to be dynamically connected and to operate with syringe needle, does not influence the inserting needle sight line; Be convenient to attach tampon, overcome minute hand stalk syringe needle inserting needle in short-term, pin mark and fall within bow member position, inconvenient hemostatic shortcoming once in a while.Be fit to the prevention of the fixing of all size syringe needle and transfusion race pin.When " transfusion vascular protection device " with the applicant has the fixing and anti-moving performance of excellent syringe needle when (ZL201020611639.0) the preferred syringe needle of pin stalk length is used, be fit to all kinds of patients and use.

2, compare with the acquired patent of above-mentioned the applicant, portal also can vertically be connected across the end of a side underframe and the middle part of opposite side underframe, and it is located, fixes before and after can making the needle handle head.Be applicable to (ZL201020611639.0) the fixing and transfusion race pin prevention of the preferred syringe needle of pin stalk length of the small size syringe needle of specification and " the vascular protection device of infusing ".Be applicable to child, old man and transfusion part limitation and narrow situation, shortened the underframe overall length, economical with materials also can be simplified the needle head structure when being connected use with infusion needle.

Description of drawings

Fig. 1 is the structural representation of this utility model.

Fig. 2 is the structural representation of the another embodiment of this utility model.

The specific embodiment

As shown in Figure 1; The utlity model has two strip underframe 1 parallel to each other; Vertical cross-over connection has a portal 2 in the end of two underframe 1, the door shape hole 3 that connects before and after being provided with in the portal 2, and the intersection of door 3 liang of inwalls in shape hole and underframe 1 bottom surface is a cambered surface 6.Bottom surface at underframe 1 has adhered layer 4, has protection sheet 5 on the adhered layer 4.

Referring to Fig. 2, this utility model can also be made two underframe 1, and one is long and the other is short, have an end face of the portal in shape hole 32 is same plane with the end face of a underframe 1 wherein, and with the structure of the vertical cross-over connection of postmedian of another underframe 1.

Said door shape hole 3 be can make the needle handle head smoothly, the snapping in of non-loosening, and guarantee the width centreline position of pin stalk between two underframe 1.

Said cambered surface 6 is not in order to make fixed mount bottom and to be urged to blood vessel and being provided with.

By the routine work of getting ready,, tear the protection sheet 5 of fixed mount adhered layer 4 off before the transfusion along transfusion section vein center line inserting needle and after guaranteeing that needle point is within the blood vessel fully; Syringe needle is ajusted along vein center line direction; The rear end face and the syringe needle fin leading edge of portal 2 are aligned, are adjacent to, and make a shape hole 3 snap in the needle handle head, gently press underframe 1; Make its bottom surface adhered layer 4 and patch jail, the back is fixed with adhesive tape.It is identical when pulling out pin operation with the needleless fixed mount that transfusion finishes.

Claims (4)

1. infusion needle fixed mount; It is characterized in that between two parallel isolating underframe (1) that by a vertical cross-over connection of portal (2) that is provided with a shape hole (3) be one, the width in door shape hole (3) should satisfy snapping in of needle handle head non-loosening and can limit infusion needle and is positioned at two underframe (1) position of center line at interval.

2. infusion needle fixed mount as claimed in claim 1 is characterized in that the intersection of a shape hole (3) two inwalls and underframe (1) bottom surface is a cambered surface (6).
