Abstract

The utility model discloses a technical proposal of a dual purpose needle device for disposable vein blood collection and transfusion. One end of the device is a scalp acupuncture with a needle sheath, the other end is a needle with a lactoprene sheath, and the scalp acupuncture and the needle are connected through a flexible communication pipe, which is provided with an on/off valve. The conjugation end of the pipe and the needle is a conical tube form flexible mouthpiece, which is elastically sleeve-connected with the adaptor of the needle. The mouthpiece can also be elastically sleeve-connected with the nipple of the infusion apparatus while the needle is removed. The utility model can be used in succession of vein blood collection and transfusion, the special intravenous infusion needle is saved and a needling to patient is subtracted.

Description

Disposable vein blood sampling, the dual-purpose needle set of infusing

Technical field

This utility model relates to medical instrument tool, specifically a kind of disposable vein blood sampling, the dual-purpose needle set of infusing.

Background technology

What medical institutions used when venous blood collection and transfusion at present is two cover needle sets.Hunan Province Liuyang City Medical Instrument and Apparatus Factory produces and sells a kind of " disposable use vein blood taking needle "; its structure one end is used to thrust the venous scalp acupuncture for band pin stalk sheath; the other end is the syringe needle that is used to thrust negative pressure Sheng blood test tube of band latex sheath; have flexible conduit to be connected between scalp acupuncture and the syringe needle, between conduit and the syringe needle for being fixedly connected.This vein blood taking needle is extensively promoted the use of, but can only supply the venous blood collection special use.In clinical patient, particularly critical patient, new inpatient, he not only needs blood sampling, and needs infusion treatment, in this case, not only need blood sampling and the two cover needle sets of infusing, and patient needs to accept continuously twice acupuncture misery at once.

The utility model content

The purpose of this utility model is a kind of disposable vein blood sampling of design, the dual-purpose needle set of infusing, with then carrying out venous transfusion behind this dual-purpose needle set venous blood collection, save special-purpose venous transfusion needle set, make the patient of continuous to-be blood sampling and transfusion reduce the acupuncture misery one time.

The purpose of this utility model is achieved in that an end of the present utility model is used to thrust the venous scalp acupuncture for band pin stalk sheath; the other end is the syringe needle that is used to thrust negative pressure Sheng blood test tube of band latex sheath; syringe needle is made up of pin stalk and the cylinder-shaped joint that is fixedly set in this pin stalk afterbody; latex sheath resilient sleeve is connected on the front end of joint; the front portion of pin stalk is positioned at the latex sheath; there is one to have elasticity and flexible UNICOM's conduit between scalp acupuncture and the syringe needle; one end of this conduit and the tail end of scalp acupuncture are fixedly connected; the other end of conduit has one to be that the elasticity of taper of one is spigot joint with conduit; this spigot joint and tail end inserting elastic socket joint; after syringe needle takes off; supravasal spigot joint can with the socket of transfusion device nipple coupling elasticity, have one to open on the conduit; Guan Shui ends.

After using method of the present utility model is venous blood collection, supravasal open and close water only is transferred to the position of pass, make catheter wall be extruded closure, venous blood in the conduit stops to flow, then syringe needle is extracted in conduit spigot joint, with the nipple of transfusion device insert spigot joint in, the position that supravasal open and close water only is transferred to out makes the conduit conducting again, can infuse.

This utility model can have been saved special-purpose venous transfusion needle set for venous blood collection and transfusion logotype, and patient is reduced by an acupuncture, has reached the purpose of this utility model, and simple in structure.Under special circumstances, this utility model also can be used for disposable blood sampling or disposable infusion list.

Description of drawings

Fig. 1 is the subjectivity figure of an embodiment of the present utility model.

Fig. 2 is the syringe needle of present embodiment and spigot joint local amplification view, and narrow and small because of drawing, hatching does not draw.

Fig. 3 is the sketch map that the open and close water of present embodiment ends.

The specific embodiment

As shown in Figure 1; one end of present embodiment is a scalp acupuncture; this scalp acupuncture is made up of scalp acupuncture stalk and handle knob (2); the lower edge of handling knob has a pipe portion; the fixedly sleeved afterbody of this pipe portion at the scalp acupuncture stalk; a pin stalk of the front end elasticity socket of pipe portion sheath (1), the rear end fixed cover of pipe portion is connected to UNICOM's conduit (3), and the tail end of conduit is the tubular elasticity of the awl with the conduit one spigot joint (5).By Fig. 1 and Fig. 2 as seen, the other end of present embodiment is a syringe needle, this syringe needle is made up of pin stalk (8) and cylinder-shaped joint (6), joint (6) is fixedly set in the afterbody of pin stalk (8), the front end resilient sleeve of joint is connected to a latex sheath (7), and the tail end of joint is inserted in spigot joint (5) and spigot joint elasticity socket.The open and close water that has an elastic sheet to make on the conduit (3) ends (4), as seen from Figure 3, the profile that this water ends is rectangular, a wealthy hole (9) more bigger than conduit outside dimension is arranged at the top of this rectangular thin plate, the slot (11) that a strip is arranged below this wealthy hole, there is a gap (10) side in wealthy hole, the wealthy hole on the rectangular plate, slot, and gap communicate with each other.Conduit is squeezed in the wealthy hole that water ends from gap (10), and conduit is extruded and cuts out in the time of in conduit is extruded to the slot that water ends, when conduit is squeezed conduit diastole conducting when getting back in the wealthy hole.

This utility model syringe needle length of said joint when engineering design is preferably long, so that medical personnel operate and do not dyed by blood stains.
