Abstract
The utility model relates to a disposable vacuum hemostix. A blood taking needle fixed at the front end of ta base is communicated with a blood collecting needle which is fixed at the back end of the base and is provided with a blood resistance rubber sheath, the middle of the base is connected with the bayonet of a pipe sleeve, E-shaped sealing plug forms a sliding fit with the inner wall of a sleeve pipe, and an observation hole for blood return is arranged at the front part of the base. The blood taking needle is inserted into the blood vessel once, multiple sampling can be carried out, the blood return can be observed, and the do-nothing operation can be prevented. The bayonet is adopted, the connecting operation is simple and convenient, and the E-shaped sealing plug can realize tightly sealing.
Description
This utility model relates to medical apparatus and instruments, particularly disposable blood taking device.
Hospital to patient's medical diagnosis on disease often by means of blood testing.Present blood-sampling method adopts the syringe blood drawing to reinject chemical examination in vitro mostly.This method is cumbersome, has also increased the chance of polluting simultaneously, is progressively eliminated.The substitute is popular in the world disposal vacuum hemostix, as Japanese " the vacuum blood collection system " that put on market in 1989.Its primary structure is the fixedly blood taking needle of two ends band needle point and one of pedestal, and pedestal connects with the blood sampling casing threads, and the sealing-plug of vacuum blood-collecting tube is slidingly matched with the blood sampling internal surface of sleeve pipe, and the end band of blood taking needle in the blood sampling sleeve pipe hinders the blood glue cover.This hemostix blood-sampling method is simple and easy to do, the cross infection that can ward off disease; Blood taking needle once inserts blood vessel, can repeatedly change the vacuum blood-collecting tube, to satisfy a plurality of chemical examination purposes; Contain different reagent in the vacuum blood-collecting tube respectively, to cooperate different blood testings.But this hemostix also has incomplete place, limits impossible each 100% thorn medium vessels as medical level, particularly to old man, child, can't observe again when hitting off the target blood vessel, this moment the vacuum blood-collecting tube is inserted and causes sky to take out; Blood sampling needle stand and casing threads join operation trouble; Conventional vacuum blood-collecting tube plug can not guarantee the permanent maintenance of vacuum state and the long-distance transport and the preservation of blood sample.
The purpose of this utility model is to provide a kind of blood back, easy and simple to handle, tight-closed vacuum blood collector observed.
Technical solution of the present utility model is: the disposal vacuum hemostix, the fixed blood taking needle of pedestal front end communicates with the receipts blood pin of the fixed band resistance in rear end blood glue cover, the pedestal middle part is fixedly connected with pipe box, the sealing-plug of vacuum tube and pipe box inwall are slidingly matched, and the pedestal front portion has the blood back observation panel; Pedestal adopts bayonet socket to connect with being fixedly connected of pipe box; Sealing-plug is " mountain " font structure of middle fluting.
According to technique scheme,, simple and easy to do with pedestal and pipe box clamping; Blood taking needle is inserted blood vessel, advance vacuum tube after the blood back observation panel is observed blood back, receive conducting in blood acupuncture broken resistance blood glue cover and sealing-plug and the vacuum tube, blood flows into vacuum tube under suction function.Extract vacuum tube in the time of need repeatedly taking a blood sample.The resistance blood glue is enclosed within the elastic force effect pinprick is sealed, and with the resistant to blood outflow, changes vacuum tube and inserts blood sampling.Blood sampling finishes and extracts blood taking needle and get final product.Because of there being the blood back observation panel can stop do-nothing operation." mountain " shape structure of fluting was sealed tighter in the middle of the vacuum tube sealing-plug adopted.
Accompanying drawing is this utility model structural representation.
In conjunction with the accompanying drawings, a kind of embodiment of the present utility model is described.The disposal vacuum hemostix, the fixed blood taking needle 1 of pedestal 3 front ends communicates with the receipts blood pin 5 of the fixed band resistance in rear end blood glue cover 6, pedestal 3 middle parts and pipe box 7 are fixedly connected, and the sealing-plug 8 and pipe box 7 inwalls of vacuum tube 9 are slidingly matched, and pedestal 3 front portions have blood back observation panel 2.Blood back observation panel 2 adopts transparent material (as plastics), the enclosed cavity conducting in blood taking needle 1, receipts blood pin 5 and the blood back observation panel 2.The middle part 4 of pedestal 3 adopts bayonet socket to connect with being fixedly connected of pipe box 7.Sealing-plug 8 is " mountain " font structure of middle open loop groove.
