Description
Technical field
The utility model relates to defend medical instruments field, more particularly to it is fixed blood taking needle certainly.
Background technique
In present medical and health industry, doctor can use blood taking needle, and to patient, blood was collected, reaches prevention or controls
Treat the purpose of disease.Existing blood taking needle includes syringe needle, handle, heparin tube etc., uses Shi doctor to hold handle and syringe needle is pierced into blood
Blood was collected for pipe, and after syringe needle enters blood vessel, doctor needs Manual press handle, so that fixed needle tail portion, is convenient for subsequent use
Syringe needle is fixed in medical adhesive tape, prevents syringe needle in blood collection procedure from falling off, and causes to carry out secondary blood drawing to patient.And it adopts in this way
Hand is needed to press at handle always during blood, doctor can not carry out other medical works, numerous inconvenience are brought to doctor, from
And affect the work quality of medical treatment and nursing.
Utility model content
The purpose of this utility model is to provide blood taking needle is fixed certainly, to solve blood taking needle in blood collection procedure, from
The problem that body can not be fixed.
In order to achieve the above objectives, the basic technology scheme of the utility model is: it is fixed blood taking needle certainly, including syringe needle,
Connecting rod, connecting leg and handle, syringe needle and connecting leg are fixedly connected on the both ends of connecting rod, and connecting rod inner hollow further includes locating plate, connecting rod
On be fixedly connected there are two convex block, handle is equipped between two convex blocks, handle is rotatably connected on connecting rod, and the two sides of handle is all provided with
There is plush copper, locating plate is fixedly connected on the two sides of connecting rod, and locating plate inner hollow, the one side of locating plate towards handle, which is equipped with, to be entered
Hole, access aperture and plush copper correspond, and the another side of locating plate is equipped with punched out, and the middle part of locating plate is equipped with adhesive sheet, bonding
Piece is equipped with and punched out be bonded head correspondingly close to the side of punched out.
From the working principle for being fixed blood taking needle are as follows: hand-held handle punctures the forearm of patient, and driving handle, by needle
Head is pushed into blood vessel, and convex block can prevent handle from sliding on connecting rod, and positioning plate gradually fits to human body hand during this
On arm.After syringe needle punctures, rotational handle, handle surrounds link rotatable, and when handle is close to locating plate, the plush copper on handle is passed through
Access aperture on locating plate simultaneously continues to move into locating plate, and plush copper squeezes the adhesive sheet in locating plate, and adhesive sheet is in locating plate
Middle mobile to forearm direction, the bonding head in adhesive sheet passes through punched out and small arm contact, and is sticked on forearm.It is rotated after being finished
Handle removes blood taking needle and can be automatically performed release and fix, facilitates removing for blood taking needle.
When by adopting the above technical scheme, hand-held handle is oriented to and is punctured to the syringe needle of blood taking needle, this is fixed in the process
Position plate gradually fits on human arm, carries out preliminary positioning and fixes, and does not have to press by hand and fix, rotates hand after puncture
Handle, the plush copper of handle, which squeezes adhesive sheet, is bonded in bonding head on arm from exposing in punched out, is fixed again, entire mistake
Cheng Wuxu manually presses forearm and fixed blood taking needle, alleviates the working strength of doctor, doctor is facilitated to operate.Hand in this programme
Handle is rotational handle, and can not only squeeze the adhesive sheet in locating plate is adhered to bonding head on forearm, and blood taking needle is facilitated to fix,
Also convenient hand-held handle carries out puncture procedure from different directions, is more convenient blood sampling operation.
Further, handle inner is hollow, and handle inner is folded with adhesive plaster, and the two sides of handle is equipped with opening.Work as blood taking needle
After syringe needle is pierced into blood vessel, adhesive plaster can be pulled straight out from the opening of handle and is fixed with handle reverse, be not necessarily to from other ground
Side tears adhesive plaster, makes to operate more convenient.
Further, to the inner recess of plush copper, the one end of plush copper far from handle is thicker at the middle part of plush copper, the middle part of plush copper compared with
Carefully, when plush copper passes through the access aperture of locating plate, because the middle part of plush copper is thinner, and the one end of plush copper far from handle is thicker, plush copper
Hole will be entered to block, will not be removed from access aperture, so that handle is fixed on locating plate, fixed without adhesive tape, saved
Material, and plush copper can also increase the frictional force between handle and hand, skidding when preventing from holding plush copper.
Further, connecting leg is hose, and the connecting portion of connecting rod and connecting leg is cased with hard tube.Hose can work as hand with free folding
When arm moves freely, hose can also be followed and be moved freely, and facilitate patient mobile.Hard tube can fetter the connection of connecting leg and connecting rod
Place when preventing connecting leg from bending, drives connecting rod bending, it is mobile to cause blood taking needle, while keeping the unobstructed of connecting portion, it is ensured that blood
It can smoothly flow out.
Further, between connecting rod and locating plate, be bonded between convex block and connecting rod, bonding can make connecting rod and locating plate it
Between, what is connected between convex block and connecting rod is more solid, and it is easy to operate to be bonded this connection type.
Further, one side of the locating plate far from handle in fitting human body forearm arc, the locating plate of arc and human body
Forearm cooperates, and compared with the locating plate of surfacing, increases the contact area of locating plate and forearm, locating plate can be made to consolidate
It is scheduled on more solid on forearm.
Further, bonding head is cone, is bonded the small end of head close to adhesive sheet.Cone bonding head makes bonding head
The function of having sucker.When being bonded head and small arm contact, the air between forearm and Nian Jie head can be squeezed out, is bonded head and forearm
Between gas pressure reduce, under the action of external atmosphere pressure, bonding head note be attached on forearm can more securely.
