Abstract
A safety entry needle can effectively prevent accidental needle puncture, and accordingly avoids the risk that medical staff contracts diseases due to accidental needle puncture. The safety entry needle comprises a needle seat (10) and a protecting sleeve (30), the needle seat (10) fixes a needle tube, and the protecting sleeve (30) is detachably mounted on the needle seat (10). The safety entry needle is characterized in that the needle seat (10) is provided with a guiding sleeve (11) longitudinally upwards extending, a slipping sleeve (20) with a needle passing through hole (21) at the top is disposed on the upper portion of the guiding sleeve (11), a locking structure is arranged between the slipping sleeve (20) and the guiding sleeve (11), a compression spring slot (23) which acts at the bottom of the slipping sleeve (20) is disposed in the guiding sleeve (11), and an elastic catch (22) capable of closing the needle passing through hole (21) is fixedly arranged in the slipping sleeve (20).
Description
Technical field
This utility model relates to clinical syringe needles, particularly a kind of safe injection needle that can effectively prevent accidental needle sticks.
Background technology
In medical matters circle, accidental needle sticks is long-standing problem.When accidental needle sticks often betides contaminated pinhead is overlapped sheath again, or behind the fresh out of pin or before doing safe handling.This acupuncture causes viral cross infection easily.Needle tubing does not overlap sheath again, and the needle tubing that does not cover sheath that is clipped in sick bed, clothes and the refuse receptacle causes more accidental puncture, makes medical personnel suffer danger.After disposing disposable use during depleted needle tubing; Generally be to recover former sheath; Sheath is the tiny pipe box of internal diameter, and the finger of holding former sheath is certainly in the place ahead of contaminated needle tubing, in the process of recovering or because of tired out, busy, luminance shortage, collision; Can produce accidental needle sticks and hinder, cause viral cross infection easily.Because accidental puncture possibly cause fatal diseases.Therefore, designing a kind of safty pin that has release mechanism, depleted needle tubing is protected, avoid scratching the people, help the healthy of people, is the urgent needs in market.
The utility model content
This utility model technical problem to be solved provides a kind of safe injection needle, can prevent accidental needle sticks effectively, thus the risk of avoiding medical personnel to catch because of accidental needle sticks.
It is following that this utility model solves the technical scheme that its technical problem adopted:
The safe injection needle of this utility model; Comprise the fixedly needle stand of needle tubing and the sheath that detachably is mounted thereon; It is characterized in that: said needle stand has vertical upwardly extending fairlead; The top of this fairlead is provided with the slippage cover that its top offered the pin through hole, has locking structure between slippage cover, the fairlead; The compression spring groove that acts on slippage cover bottom is set in fairlead, and the setting of slippage cover internal fixation can be blocked the elastic block piece of pin through hole.
The beneficial effect of this utility model is; Utilization can be sealed the slippage cover of pin through hole and protected contaminated needle tubing; Make medical personnel's hands be positioned at the needle point rear; Can prevent simultaneously that needle tubing from coming off skids off, thus can prevent accidental needle sticks effectively, thus the risk of avoiding medical personnel to catch because of accidental needle sticks; Simple in structure, easy to operate.
Description of drawings
This description comprises following three width of cloth accompanying drawings:
Fig. 1 is the structural representation before this utility model safe injection needle uses;
Structural representation when Fig. 2 is the use of this utility model safe injection needle;
Fig. 3 is the structural representation after this utility model safe injection needle is used to complete;
Parts shown in the figure, toponym and pairing labelling: needle stand 10, fairlead 11, circumferential groove 12, slippage cover 20, mistake pin through hole 21, elastic block piece 22, compression spring groove 23, alignment pin 24, sheath 30.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment this utility model is further specified.
With reference to Fig. 1, the safe injection needle of this utility model comprises the fixedly needle stand 10 of needle tubing and the sheath 30 that detachably is mounted thereon.Said needle stand 10 has vertical upwardly extending fairlead 11, and the top of this fairlead 11 is provided with the slippage cover 20 that its top offered pin through hole 21, and slippage is overlapped between 20 fairleads 11 and had locking structure; In fairlead 11, be provided with and act on the compression spring groove 23 that 20 bottoms are overlapped in slippage, the elastic block piece 22 that 20 internal fixation settings can be blocked pin through hole 21 is overlapped in slippage.With reference to Fig. 2, take off sheath 30 during use.With reference to Fig. 3.After injection finishes, remove slippage and overlap the locking between 20 fairleads 11, under the effect of compression spring groove 23; Slippage cover 20 is along the outside slippage of needle tubing; After the head of elastic block piece 22 was crossed needle tubing needle point position, promptly bullet overlapped 20 middle lines to slippage and sheltered from pin through hole 21, and the cover of slippage after this 20 can not be again to lower slider; Needle tubing is limited in the slippage cover 20; Make medical personnel's hands be positioned at the needle point rear, thus accidental needle sticks can be prevented effectively, thus the risk of avoiding medical personnel to catch because of accidental needle sticks.
Fig. 2 and Fig. 3 show the locking structure that a kind of structure is the simplest and use is produced, and locking structure comprises that being arranged on slippage overlaps the alignment pin 24 on 20 outer walls, and the circumferential groove with vertical breach 12 that is arranged on fairlead 11 upper ends.For guaranteeing that needle tubing is limited in the slippage cover 20, said elastic block piece 22 is L shaped.
Some principles of the above this utility model safe injection needle that just explains through diagrams; Be not be to this utility model be confined to shown in described concrete structure and the scope of application in; So every the modify and equivalent that might be utilized all belongs to the claim that this utility model is applied for.
