Description

A kind of lid of infusion vessel

Technical field

The utility model belongs to curable product field, more specifically to a kind of lid of infusion vessel.

Background technique

Infusion vessel generally includes infusion bottle and infusion bag, and inside is packed into medical fluid, when being infused to patient, some need to The other kinds of medical fluid of mixing in medical fluid, is pushed into infusion vessel after being drawn other medical fluids by syringe by lid, usually A lid with medical rubber plug is provided on infusion vessel, in infusion, the piercing needle of infusion apparatus is worn out medicinal on lid Rubber plug protrudes into inside infusion vessel, this piercing needle wants greatly more relative to the needle diameter of syringe, and piercing needle is worn first It breaks medical rubber plug and needs to overcome very big resistance during protruding into, be not easy to penetrate, secondly medical rubber plug is easy to aging, by temperature shadow Sound is very big, some medical rubber plugs are second-rate, and when thicker piercing needle penetrates, medical rubber plug generation extremely easy to drop is punctured Exfoliation simultaneously floats in infusion vessel, tiny puncture exfoliation may follow medical fluid by infusion apparatus enter human body cause it is biggish Security risk.

Utility model content

In view of the deficiencies of the prior art, the utility model provides a kind of reduction puncture needle for transfusion and penetrates to infusion and holds Resistance in device, while not having rubber and being punctured and form the lid for puncturing the infusion vessel that exfoliation enters in medical fluid.

To achieve the above object, the utility model provides following technical solution: a kind of lid of infusion vessel, including Main body, ecto-entad is extended groove in the main body, and the bottom of the groove is in arc surfaced, and the groove, which is formed, to be punctured Hole.

The rubber injection piece that the syringe needle of syringe can be made to penetrate is additionally provided in the further main body.

The further rubber injection piece and puncturing hole are mutually indepedent.

The further groove is provided with cricoid reinforcing rib, the lowest part of the reinforcing rib and groove at bottom It is formed there are space and punctures area.

The sidewall thickness of the further groove to bottom portion of groove from being gradually reduced at reinforcing rib.

The sealing element that can be opened, the sealing element covering groove and rubber injection are provided in the further main body Part.

The further sealing element is the sealing strip that can be torn.

Liquid flow direction mark is provided in the further main body at puncturing hole and rubber injection piece.

Compared with prior art, the utility model has the beneficial effects that the puncture needle in infusion apparatus is worn to infusion vessel When, save across original medical rubber plug process, but by groove, groove puncture area closer to bottom position its wall thickness is got over Small, puncture needle is gradually protruded by the top of groove and the bottom of contact arc planar, and the tip of puncture needle will directly contact groove Lowest part, herein and at wall thickness minimum, resistance is smaller when first thus puncture needle penetrates infusion vessel inside, is secondly puncturing When can't generate puncture exfoliation；And when injecting other kinds of medical fluid into infusion vessel, because the syringe needle of syringe penetrates Injection after the completion of need to extract, therefore still use rubber injection piece, the needle diameter of one syringe is smaller, be relatively easy to across Rubber injection piece prevents leakage secondly rubber injection piece can directly block pin hole after extraction.

Specific embodiment

It is described further referring to figs. 1 to embodiment of the Fig. 5 to the lid of the utility model infusion vessel.

A kind of lid of infusion vessel, including main body 1, ecto-entad is extended groove in the main body 1, described recessed The bottom of slot is in arc surfaced, and the groove forms puncturing hole 5.

When needing to be infused, the piercing needle that infusion apparatus connects is protruded into and to the bottom of arc surfaced along groove, is only needed It gently firmly can puncture bottom to protrude into inside infusion vessel, bottom contact regions, that is, contact surface of piercing needle and arc surfaced is small.

The present embodiment is preferably additionally provided with the rubber injection piece 4 that the syringe needle of syringe can be made to penetrate in the main body 1.

Wherein the optional General Purpose Rubber of the material of rubber injection piece, latex or silica gel etc. meet medical standard, and can It is injected device syringe needle and punctures while having self-healing capability, i.e., syringe needle is pierced to the material of shut-off capacity at needle outlet.

Rubber injection piece 4 is the needle of syringe when adding other kinds of medical fluid to need to inject in infusion vessel Thus head penetrates, thinner syringe needle easily penetrates first, and rubber injection piece 4 can block the anti-leak-stopping of pin hole automatically after secondly extracting Liquid.

Preferably the rubber injection piece and puncturing hole 5 are mutually indepedent for the present embodiment, facilitate processing in production first, It is secondary to be convenient for distinguishing when in use.

Preferably the groove is provided with cricoid reinforcing rib 7, the reinforcing rib 7 and groove to the present embodiment at bottom Lowest part there are space formed puncture area 6, the diameter of piercing needle is gradually increased from tip to rear side, is worn in piercing needle Cross groove puncture area 6 after, piercing needle will move closer to reinforcing rib 7 until contact, piercing needle can not continue to penetrate at this time, The intensity that groove can be increased first, prevents from being torn, and secondly piercing needle and mutual extrusion at reinforcing rib 7, enhance leakproofness.

The sidewall thickness of the preferred groove of the present embodiment to bottom portion of groove from being gradually reduced at reinforcing rib 7.

The thickness for reducing bottom portion of groove, punctures convenient for piercing needle and protrudes into inside infusion vessel.

The present embodiment is preferably provided with the sealing element that can be opened in the main body 1, the sealing element covering groove and Rubber injection piece 4, wherein the sealing strip 2 that can be torn can be used in sealing element, and the form that sealing cover can also be used is covered in main body 1 On, for using the preceding effect that groove and rubber injection piece 4 are isolated with pollutant in infusion vessel.

Aluminium foil can be used in preferred sealing strip 2, and aluminium foil is pasted on the body 1, prevents groove and rubber injection to reach The effect that part 4 pollutes, tears it when need to use.

The present embodiment is preferably provided with liquid flow direction mark in the main body 1 at puncturing hole 5 and rubber injection piece 4 Know 3, liquid flow direction mark 3 is indicated by an arrow in the present embodiment.

The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
