Inner sticky pad type film sealed vacuum hemostixTechnical field
The present invention relates to a kind of inner sticky pad type film sealed vacuum hemostix.Particularly relate to the welding of a kind of and vacuum test tube mouth or glue the diaphragm seal inner face straight forming that the boundary becomes integral body and elastic packing mat structure that is adhesively fixed voluntarily and the vacuum test tube that has negative pressure.
Technical background
At present, the sealing means of the employed vacuum test tube of the market mainstream is to adopt rubber stopper to insert to realize in the vacuum test tube mouth sealing and diaphragm seal to be affixed on that the vacuum test tube mouth seals and in forms such as the outside of film adhesive rubber pads, when vacuum test tube adopts plastic material, reveal vacuum in the time of then long term storage can being caused for the rubber stopper seal mode, external coordination kit purchase cost is high and offal treatment toxicity is big, contaminated environment is serious etc., needle point puncture great efforts, and adopt the diaphragm seal outside often to cause the cracked problem such as vacuum test tube that enters of bonding not firm and adhesive in the rubber blanket mode of adhesive adhesion, the volatilization of adhesive causes air pollution in process of production, poison operator, also toxigenicity gaseous contamination environment during castoff burning, rubber blanket is bonding come off easily when insecure or ftracture and can't finish blood sampling or blood sampling volume inaccurate, the needle point penetration Resistance is big, and manually-operated is wasted time and energy and accidentally injured easily hand to cause the puncture sampling probe that infects in addition equipment also be to cause damage easily.
In addition, in use, if desired to surface sterilization, then the product for rubber stopper or rubber blanket is many and dark and puckery owing to corner angle, is difficult for thoroughly finishing and residual disinfectancy agent easily, discharges poisonous gas when incineration of waste is handled and causes environmental pollution.
Summary of the invention
In order to solve above-mentioned existing in prior technology defective, the invention provides a kind of inner sticky pad type film sealed vacuum hemostix, at first cushion is bonded in the lower surface of diaphragm seal and is positioned at diaphragm seal and the formed cavity in vacuum test tube sealing back, gapped existence between the inwall of cushion neighboring and vacuum test tube oral area, the neighboring of diaphragm seal lower surface and the sealing of vacuum test tube mouth; Cushion is to be moulded the final curing that stickiness molding and that rely on the cushion molding initial stage is bonded in the diaphragm seal lower surface and finishes this cushion after placement naturally by direct coating at the lower surface of ready-made diaphragm seal, and the thickness of this cushion is 0.1 millimeter to 10 millimeters; Do not have adhesive or other the third composition between cushion and the diaphragm seal, cushion is not pushed by other object except that diaphragm seal yet; The surface of cushion has hydrophobic character, and its material is a silicone rubber; The design of diaphragm seal middle part has protruding guiding spill to the vacuum test tube intracavity, and the degree of depth of this guiding spill is 0.1 millimeter to 5 millimeters, and cushion then covers the outstanding position and the periphery of guiding spill below diaphragm seal.
Good effect of the present invention is: cushion design has been guaranteed that in vacuum test tube inside bonding back is unmanned for disturbing and the people causes during for taking and placing comes off, adopt technique for sticking voluntarily not need the use of adhesive in addition, when having avoided making the pollution of operation and when using cracked the coming off of adhesive be punctured pin and scrape and take off and fall into vacuum test tube inside and cause polluting or stopping up needle tubing, what the present invention used in addition is silastic material, composition is more stable, burn residual and the volatilization after composition pollution-free, in diaphragm seal outer surface design circular depressed is arranged, excessively slick and sly and shallow easy sterilization and cleaning; More outstanding advantage is that the sampling puncture needle for puncture blood collecting pin and inspection machine has the effect that minimum penetration Resistance can reduce the damage of equipment needle point is played the protection detecting instrument.
Do not have poisonous fume to discharge during castoff burning, burn afterproduct and be mainly water and carbon dioxide etc.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing:
Accompanying drawing is an inner sticky pad type film sealed vacuum hemostix structural representation proposed by the invention;
The specific embodiment
As shown in drawings, be inner sticky pad type film sealed vacuum hemostix proposed by the invention, comprise vacuum test tube 3, diaphragm seal 1 and cushion 2, described cushion 2 is bonded in the lower surface middle position of diaphragm seal 1 and is positioned at diaphragm seal 1 and the formed cavity in vacuum test tube 3 sealing backs, gapped 6 exist between the inwall of cushion 2 neighborings and vacuum test tube 3 oral areas, the neighboring of the lower surface of diaphragm seal 1 and 4 sealings of vacuum test tube mouth; Cushion 2 is to be moulded lower surface that stickiness molding and that rely on the cushion molding initial stage is bonded in diaphragm seal 1 by direct coating and finish the final curing of this cushion 2 after placement naturally at the lower surface of ready-made diaphragm seal 1, and the thickness of this cushion 2 is 0.1 millimeter to 10 millimeters; Do not have adhesive or other the third composition between cushion 2 and the diaphragm seal 1, cushion 2 is not pushed by other object except that diaphragm seal 1 yet; The surface of cushion 2 has hydrophobic character, and assurance liquid reagent or blood is not with cushion 2 adhesions and dissolve other interference component, and its material is a silicone rubber; The design of diaphragm seal 1 middle part has protruding guiding spill 5 to the vacuum test tube intracavity, and the degree of depth of this guiding spill 5 is 0.1 millimeter to 5 millimeters, and 2 of cushions cover the outstanding position and the periphery of guiding spill 5 below diaphragm seal 1.
The diaphragm seal 1 that directly will have cushion 2 when making finished product is positioned over vacuum test tube mouth 4, cushion 2 does not push with any object towards cuvette cavity and cushion 2, merge or adhering and sealing is fixed at evacuation condition lower seal film 1 and vacuum test tube mouth 4, make cushion 2 directly be sealed in the tube chamber of vacuum test tube 3, puncture needle elder generation puncture through seal film 1 pierced through cushion 2 again and enters in the tube chamber in the vacuum test tube 3 when blood sampling was used.
The present invention has realized the direct coated and molded of silicone rubber also is bonded in voluntarily the inner surface of diaphragm seal 1; pollution when having avoided artificial damage and having stored transportation; also be convenient to the sterilization and the cleaning of outer surface; the resistance that has reduced simultaneously the needle point puncture has more been protected equipment and has been lowered personnel's operation easier, in addition the burning of garbage clean environment firendly more.
