Abstract

The utility model discloses a dual-purpose needle for blood sampling and vein transfusion; the dual-purpose needle is provided with a thin flexible tube (4); one end of the thin flexible tube is connected with a vein puncture needle (1); the other end is connected with a transparent hard plastic short tube (5) with a bulkhead made of flexible material; the short tube is connected with a blood sampling needle and a set of transfusion device. The dual-purpose needle for blood sampling and vein transfusion can accomplish the blood sampling and vein transfusion without processing twice vein puncture on the patient.

Description

Blood specimen collection and venous transfusion two purpose meedle

Technical field

This utility model relates to a kind of medical apparatus and instruments, particularly a kind of medical apparatus and instruments that can be used as blood collection and venous transfusion.

Background technology

In known practice, hospital takes a blood sample and typically uses a kind of negative pressure blood taking needle the patient is taken a blood sample, described negative pressure blood taking needle comprises a blank pipe, the inside formation negative pressure of bleeding, the mouth of pipe seals with rubber cap, a blood taking needle is supporting with it, described blood taking needle has handle, one end has little pin, overlap rubber sleeve on the little pin, the other end is with one section rubber tubule, one end of tubule is connected with a radicular vein puncture needle, earlier venipuncture is needled into patient's vein during use, then the stylet of blood taking needle rubber sleeve is gone in the rubber cap of the mouth of pipe, blood is drawn in the pipe under the effect of negative pressure, this blood taking needle uses certain convenience, but also exist not enough, the process that promptly patient that should take blood specimen to carry out the venous transfusion treatment is again existed twice venipuncture, gather pin and carry out venipuncture second time again and do the infusion treatment preparation because gather need to pull out behind the good required blood specimen, this process is painful to all patients, especially to infant, the obese patient, the critical patient, because difficulty is compared in their venipuncture often, meanwhile, also increased nursing staff's working strength, therefore this situation must be improved.

The utility model content

The purpose of this utility model is to provide a kind of can overcome the known technology shortcoming, can reduce the sufferer misery, easy to use and reduce operation sequence, serves the patient's that not only need take a blood sample but also need infuse a kind of improved blood specimen collection and venous transfusion two purpose meedle clinically.

For achieving the above object, scheme of the present utility model is: a small hose is set, one end connects a venipuncture needle, and one of another termination has flexible material to form the transparent hard plastic short tube of plug, and described short tube connects a blood collecting pin or a cover infusion set.

Further scheme comprises that described plug is a rubber cap.

Adopt such scheme, fix after venipuncture is needled into patient's vein, subsequently patient's blood-sample withdrawal and transfusion operation are all used same venipuncture needle, need not every operation one-time puncture once, reduced the sufferer misery, thereby realized the purpose of this utility model.

Below in conjunction with diagram and embodiment scheme is described in more detail.

Fig. 2 is the front view of the blood collecting pin after improving among Fig. 1.

The specific embodiment

As described in Figure 1; the disposable blood sample of this programme is gathered pin and is comprised a radicular vein puncture needle 1; handle 2 is arranged above; under packed state, there is a protective sleeve 3 to cover syringe needle usually; one end of pin 1 connects a small hose 4; one end of flexible pipe 4 and one slightly are coarser than 4 transparent hard plastic short tube 5 and join; the length of short tube 5 slightly is longer than a radicular vein puncture needle; short tube 5 one ends wear rubber cap 6 as plug; rubber cap 6 is a medical grade rubber; performance is pliable and tough, and syringe needle pierces through in the short tube 5 that plug enters cavity easily, and is relied on the retraction force frictions to fix by rubber cap 6.

The transparent hard plastic short tube 5 of this programme relies on rubber plug to be connected respectively with a blood collecting pin or a cover infusion set, described blood collecting pin as shown in Figure 2, the blood collecting pin of present embodiment is improved on the basis of known technology, the needle handle 7 that comprises a hollow, one section syringe needle 8 and 9 are all exposed in two ends, be with a root rubber cover 10 on the syringe needle 8, technologically 8 and 9 also can be all a pin, in position package needle handle 7 and hold part as hands.

Device of this programme such as venipuncture needle 1, plug 6 on flexible pipe 4 and short tube 5 and 5 is integral, on the blood collecting pin 9 thrust fully pack after plug 6 enters in the short tube 5, under plant states, become medical apparatus and instruments after the ethane via epoxyethane sterilization, during blood sample collection, in packing, take out the two purpose meedle of sterilization treatment, venipuncture needle 1 is thrust in the patient's vein pipe and fix needle handle 2 with medical proof fabric rapidly, 8 of Fig. 1 is thrust in the cap test tube of the test tube of being with negative pressure, blood just flows in vitro along negative pressure, meanwhile effusive blood has also drained all air in " two purpose meedle " plastic tube, after having gathered blood specimen, blood collecting pin 9 is extracted rubber cap 6, rubber cap has extremely strong retraction force and restores to the original state immediately, patient's blood just can not exosmose or flows out from rubber cap 6 like this, at this moment, behind the routine disinfection rubber cap, piercing needle on the off-the-shelf transfusion device is thrust rubber cap 6 fully and enter in the transparent hard plastic short tube 5, properly fixedly thrust the vein puncture syringe needle in the rubber cap again, just can carry out venous transfusion, certainly, liquid that can not exosmoses from rubber cap.The patient has both reduced patient's misery with regard to not carried out the venipuncture second time more like this, has also alleviated nursing staff's workload simultaneously, and therefore, this device is feasible.

Claims (4)

1, a kind of blood specimen collection and venous transfusion two purpose meedle, it is characterized in that: a small hose (4) is set, one end connects a venipuncture needle (1), one of another termination has the transparent hard plastic short tube (5) of the plug of flexible material formation, and described short tube connects a blood collecting pin or a cover infusion set.
