Description
Technical field
This utility model relates to a kind of medical treatment blood sampling apparatus, particularly relates to a kind of blood taking tube that can detect vacuum.
Background technology
China is populous nation, along with growth in the living standard, people pay close attention to the healthy of self more, medical consumable goods in disease treatment and prevention health check-up increases, blood taking tube particularly as main bases blood sampling chemical examination consumes huge, existing most of blood taking tube inside is all vacuum and has medicament, after venipuncture, blood taking tube is thrust in another hose connection for piercing needle termination during blood sampling, by the internal negative pressure of blood taking tube by venous blood suction blood taking tube, there is the advantage of quick and safe, progressively to replace blood collection needle, because the internal negative pressure of blood by blood taking tube is extracted out, when this will ensure to take a blood sample, blood taking tube will keep enough negative pressure, otherwise blood can not be adopted or can not enoughly take a blood sample, and due to transport or store and the impact of the environmental factors such as time, often there is the phenomenon of indivedual blood taking tube without negative pressure or negative pressure deficiency, impact blood sampling efficiency, also the contradiction between doctors and patients is easily caused, before blood sampling, the judgement of blood taking tube vacuum is particularly important, and existing blood taking tube can not judge intuitively, this respect still needs to be improved.
Utility model content
In order to solve the problem, this utility model provides a kind of blood taking tube that can detect vacuum.
The technical solution adopted in the utility model is: a kind of blood taking tube that can detect vacuum, comprise blood-collecting tube, cork and vinyl cover, it is characterized in that vinyl cover top is provided with insert port, vinyl cover inside is provided with ring-shaped depression by the sidewall at top, cork is provided with the annular seal groove that blood-collecting tube opening port inserts, cock body outside annular seal groove embeds in ring-shaped depression, vinyl cover inwall is provided with the cannelure being extended to ring-shaped depression by edge, vinyl cover sidewall is provided with longitudinal opening, resilient strip is provided with in longitudinal opening, resilient strip is connected away from side, vinyl cover top with longitudinal opening, resilient strip free end is connected with the projection of outstanding vinyl cover side wall inner surface, protruding and ring-shaped depression possesses spacing, cork is that printing opacity elastomeric material is made, the spherical depression of revolution excision is provided with below cork center, annular holddown groove is provided with around spherical depression, a red flexible membrane is provided with below cork, flexible membrane swells in spherical depression, flexible membrane is provided with the salient point with spherical depression surface contact, is connected with the insertion ring that can insert annular holddown groove around flexible membrane.
Further, the top of described flexible membrane protuberance be provided with pivotal above with the red indicator collet of spherical depression surface contact.
Further, above described red indicator collet, center is provided with pit.
Further, described insertion ring edge is provided with overhead kick, inserts between ring and annular holddown groove and is filled with fluid sealant.
After this utility model insertion ring inserts annular holddown groove, extruding flexible membrane discharges most of implication, because flexible membrane is provided with salient point, again under salient point supporting role, still partial air is left between flexible membrane and spherical depression surface, then glue sealing is dripped to annular holddown groove, during gland evacuation, under suction function, flexible membrane and salient point leave spherical depression surface, formed between flexible membrane and spherical depression surface with negative pressure space, red flexible membrane is can't see through cork after gland, during when vacuum decline in blood-collecting tube or without vacuum, between flexible membrane and spherical depression surface under the suction function of space, flexible membrane is near spherical depression, the redness instruction of flexible membrane is seen through cork, substandard product can be separated in time, and longitudinal gap can carry out evacuation and the depth localization of evacuation protecgulum lid better with protruding arranging, and does not affect evacuation rear pressing cover again.

Detailed description of the invention
This utility model embodiment is just like Fig. 1, shown in 2, this blood taking tube that can detect vacuum is provided with blood-collecting tube 1, cork 2 and vinyl cover 3, vinyl cover top is provided with insert port, for inserting syringe needle, vinyl cover inside is provided with ring-shaped depression 4 by the sidewall at top, cork is provided with the annular seal groove 5 that blood-collecting tube opening port inserts, cock body outside annular seal groove embeds in ring-shaped depression, vinyl cover inwall is provided with the cannelure 6 being extended to ring-shaped depression by edge, vinyl cover sidewall is provided with longitudinal opening 7, resilient strip 8 is provided with in longitudinal opening, resilient strip is connected away from side, vinyl cover top with longitudinal opening, resilient strip free end is connected with the projection 9 of outstanding vinyl cover side wall inner surface, protruding and ring-shaped depression possesses spacing, before evacuation, vinyl cover covers on blood taking tube opening port, the degree of depth is to high spot, protruding restriction insertion depth, inner air tube of taking a blood sample during evacuation is flowed out fast by longitudinal opening, blood taking tube opening port expression lobes during gland, resilient strip distortion blood taking tube opening port inserts annular seal groove, it is higher that this process forms vacuum reliability, cork is that printing opacity elastomeric material is made, for translucent, the bright-colored of pressing close to its surface can be seen through cork, the spherical depression 10 of revolution excision is provided with below cork center, be provided with annular holddown groove 11 around spherical depression, be provided with a red flexible membrane 12 below cork, flexible membrane swells in spherical depression, flexible membrane is provided with the salient point 13 with spherical depression surface contact, is connected with the insertion ring 14 that can insert annular holddown groove around flexible membrane, insert ring edge and be provided with overhead kick 15, during insertion, may be used for press-in, insert between ring and annular holddown groove and be filled with fluid sealant 16, salable connection.After the present embodiment insertion ring inserts annular holddown groove, extruding flexible membrane discharges most of implication, because flexible membrane is provided with salient point, then under salient point supporting role, still leave partial air between flexible membrane and spherical depression surface, then drip glue sealing to annular holddown groove; During gland evacuation, under suction function, flexible membrane and salient point leave spherical depression surface, formed between flexible membrane and spherical depression surface with negative pressure space, after gland, can't see red flexible membrane through cork, during when vacuum decline in blood-collecting tube or without vacuum, between flexible membrane and spherical depression surface under the suction function of space, flexible membrane, near spherical depression, is seen the redness instruction of flexible membrane, can be separated substandard product in time through cork.
This utility model embodiment two as shown in Figure 3, this blood taking tube that can detect vacuum on the basis of embodiment one, the top of flexible membrane protuberance be provided with pivotal above with the red indicator collet 17 of spherical depression surface contact, instruction can be made more clearly.
During enforcement, on red indicator collet, pit can being provided with in center, inserting for guiding syringe needle.
Be only this utility model preferred embodiment in sum, all equivalence modifications of doing according to the application and prior art are added and are all considered as this utility model technology category.
