Abstract
The utility model discloses a disposable puncture outfit component. The disposable puncture outfit component comprises a puncture needle and a channel body that are matched with each other, wherein the front end of the puncture needle is provided with a cusp; the channel body comprises a channel body outer tube; blood grooves and strutting raised lines are arranged on the cusp; a sealing ring is sleeved with the exterior of the channel body in an interference fit manner. The disposable puncture outfit component has the advantages that the operation time is short, the operation is simple, and the requirement of humanized medical care can be met.
Description
Technical field
This utility model relates to technical field of medical instruments, especially relates to a kind of disposable puncture device assembly.
Background technology
Conventionally, the puncture needle of disposable perforator, all only overweights the sharp-pointed performance that improves head, often causes while inserting, between skin and puncture instrument, to form vacuum band and cause wound, causes post-operative wound to increase recovery time.Meanwhile, doctor needs left rotation and right rotation and the apparatus that fluctuates just can puncture to reach the object of setting up operation path when puncture.Like this, cause operating time increase and surgical wound wound is increased.And, left rotation and right rotation and fluctuating while setting up after passage because of puncture, make the contact surface of set up passage and skin cannot be completely airtight and fixing, cause gas or blood from gap, overflow or spray, cause doctor when operation must allow assistant at any time wiping pipe shaft with contact skin around to keep cleaning.That is, common puncture needle causes operating time slow, and operation is comparatively complicated, and cannot reach the requirement of the hommization medical treatment of current promotion.
Utility model content
The purpose of this utility model is to provide a kind of disposable puncture device assembly, and it is short that it has operating time, simple to operate, and can reach the feature that hommization medical treatment requires.
The technical scheme that this utility model adopts is: disposable puncture device assembly, comprise the puncture needle and the channel body that are used in conjunction with, wherein, this puncture needle front portion has tip, this channel body includes channel body outer tube, described tip is provided with blood groove and struts raised line, and the cover of described channel body outside pipe interference fit has sealing ring.
Described blood groove and strut raised line and be symmetrical 2 of axial line along this puncture needle.
Described any blood groove and any angle strutting between raised line are 90 °.
The advantage that this utility model has is: operating time is short, simple to operate, and can reach hommization medical treatment requirement.In use, puncture needle struts under the effect of raised line at this blood groove and this disposable puncture device assembly of the present utility model, can enter in human body very smoothly, thereby reduce operating time, increased operation safety.Meanwhile, set sealing ring on this channel body outer tube, can prevent that gas or blood from overflowing or spraying from gap, reaches airtight and fixed function preferably, is beneficial to operation and carries out smoothly, has reached the requirement of hommization medical treatment.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further illustrated:
Fig. 1 is the front view of puncture needle in embodiment of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to view;
Fig. 3 is the front view of channel body in embodiment of the present utility model.
In figure: 10, puncture needle, 11, tip, 12, blood groove, 13, strut raised line; 20, channel body, 21, channel body outer tube, 22, sealing ring.
The specific embodiment
Embodiment, is shown in shown in Fig. 1 to Fig. 3: disposable puncture device assembly, comprises the puncture needle 10 and the channel body 20 that are used in conjunction with.That is, this puncture needle 10 will form passage after skin penetrating, and this channel body 20 is inserted in this passage, is convenient to operating theater instruments and enters human body by this channel body 20.Wherein, these puncture needle 10 front portions have tip 11, and this channel body 20 includes channel body outer tube 21.Further say, this tip 11 is provided with blood groove 12 and struts raised line 13.Obviously, this blood groove 12 and this trend that struts raised line 13 are same as the axial line of this puncture needle 10.Optimize, this blood groove 12 and this strut raised line 13 and are symmetrical 2 of axial line along this puncture needle 10.More excellent, any blood groove 12 and any angle strutting between raised line 13 are 90 °.Certainly, this angle refers to blood groove 12, struts the angle between the line of axial line of raised line 13 and this puncture needle 10.Further say, the cover of these channel body outer tube 21 outside interference fit has sealing ring 22.
Operation principle of the present utility model: when puncture, gas can circulate from blood groove recess, and strut raised line and strengthen strutting effect, skin is not had and be coated or be absorbed in the puzzlement in groove, while having avoided generally using puncture needle at present, cause vacuum state and make skin layer along with thrusting of puncture needle, pull the puncture obstacle of formation, then make doctor can more conveniently will wear in time pin insertion human body and check and operation path with foundation.Simultaneously, after passage forms, fixing sealing ring on this channel body outer tube, set up the tight secure bond of passage and human body to reach good airtight usefulness, avoided that the general passage using causes at present seal is poor makes the situation that in operation, apparatus skids off then, make doctor when checking or perform the operation, effectively kept good surgical operation space, then make operation project safer, quick.
The foregoing is only preferred embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes this utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
