Description
Technical field
The utility model relates to the field of medical instrument technology, and in particular to a kind of Novel blood taking needle.
Background technique
Currently, common disposable blood taking needle is when in use, needle guard is pulled out, pricking hazard is be easy to cause.But really danger
Danger is to dispose the stage after the completion of blood sampling, after extracting out of person of blood collecting body, when carrying out waste disposal, is either put into profession
Process cartridge still take needle guard again, be all easy the danger being wounded by stabbing, cause the serious consequences such as medical staff infection.
Currently, common non-disposable blood taking needle is after use, need to needle guard on pinhead sleeve to protect syringe needle, but in this way
One carrys out medical worker when needle guard is covered upper syringe needle, due to syringe needle is very thin and the diameter of needle guard is also little, be easy to stab finger, make
At serious consequences such as medical staff infections.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of Novel blood taking needles.
In order to achieve the above objectives, the utility model provides the following technical solutions: a kind of Novel blood taking needle, including needle stand, leads
Pipe and blood taking needle, needle stand and blood taking needle are connected to the both ends of conduit, and needle stand includes needle ontology, needle handle, needle tip protection sleeve and elasticity
Part, one end of needle ontology are fixed in needle handle and connect with conduit, and the other end of needle ontology extends outwardly；Needle tip protection sleeve activity
Ground is sleeved on needle ontology, and needle tip protection sleeve is accommodated in needle handle and is connected together with needle handle；Elastic component is compressively set to
In needle handle, one end of elastic component and the inner wall of needle handle are connected, and the other end of elastic component and the end of needle tip protection sleeve connect.
Further, outwardly projecting retention bead is equipped in the surface middle part of needle tip protection sleeve.
Further, limit hole is equipped on needle handle, retention bead is fastened in limit hole.
Further, it is equipped with ejection piece in needle handle outer surface, one end of ejection piece extends into limit hole.
Further, the cross sectional shape semicircular in shape of retention bead and limit hole.
Further, elastic component is spring.
Further, the length of needle tip protection sleeve is more than or equal to the length outside needle ontology leakage needle handle.
The utility model has the beneficial effects that: medical worker no longer needs to after having used the blood taking needle of the utility model
Needle guard is put on into syringe needle, solve the problems, such as disposably to stab doctor using rear presence with blood collection needles or suffers from personnel.
Detailed description of the invention
In order to keep the purpose of this utility model, technical scheme and beneficial effects clearer, the utility model provides as follows
Attached drawing is illustrated:
Fig. 1 is a kind of structural schematic diagram of Novel blood taking needle of the utility model.
Fig. 2 is a kind of structural schematic diagram of the needle stand of Novel blood taking needle of the utility model.
Fig. 3 is a kind of use state diagram of the needle stand of Novel blood taking needle of the utility model.
In figure, 1 is needle stand, and 2 be conduit, and 3 be blood taking needle, and 11 be needle ontology, and 12 be needle handle, and 13 be needle tip protection sleeve, 14
It is retention bead for elastic component, 15,16 be limit hole, and 17 be ejection piece.
Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments, so that those skilled in the art
The utility model can be better understood and can be practiced, but illustrated embodiment is not as the restriction to the utility model.
As shown in Figure 1, a kind of Novel blood taking needle of the utility model, including needle stand 1, conduit 2 and blood taking needle 3, needle stand 1 and adopt
Blood needle 3 is connected to the both ends of conduit 2.
As shown in Fig. 2, needle stand 1 includes needle ontology 11, needle handle 12, needle tip protection sleeve 13 and elastic component 14, needle ontology 11
One end is fixed in needle handle 12 and connect with conduit 2, and the other end of needle ontology 11 extends outwardly.Needle tip protection sleeve 13 actively covers
On needle ontology 11, and needle tip protection sleeve 13 is accommodated in needle handle 12 and is connected together with needle handle 12.Elastic component 14 is compressed
Ground is set in needle handle 12, and one end of elastic component 14 is connect with the inner wall of needle handle 12, the other end and needle tip protection sleeve of elastic component 14
13 end connection.
It is equipped with outwardly projecting retention bead 15 in the surface middle part of needle tip protection sleeve 13, limit hole is equipped on needle handle 12
16, retention bead 15 is fastened in limit hole 16 to realize being connected together between needle tip protection sleeve 13 and the needle handle 12.
Ejection piece 17 is equipped in 12 outer surface of needle handle, and ejection piece 17 has elasticity, and one end of ejection piece 17 is to limit hole 16
Interior extension.
In the present embodiment, the cross sectional shape semicircular in shape of retention bead 15 and limit hole 16, elastic component 14 are spring.
