Abstract
The utility model discloses a sealing plug for a double-layered vacuum hemostix, which comprises a plug body (1) and plug necks (2 and 3). The plug necks consist of a first plug neck (2) and a second plug neck (3) which are arrayed in a stepped manner. The first plug neck (2) is tapered from top to bottom, an annular groove (5) is arranged at a joint of the plug body (1) and the first plug neck (2), an inner groove is arranged in the middle of the top of the plug body (1), and the bottom of the second plug neck (3) is sunken inwards. By the aid of the structure, tube openings of the double-layered vacuum hemostix are waterproof and have fine airtightness when sealed, needed force for plugging and unplugging the sealing plug is small, the sealing plug can simultaneously block the tube openings of inner and outer tubes of the double-layered vacuum hemostix, blood samples can be separated from the external effectively, and simultaneously, the sealing plug is more convenient in use and operation.
Description
Technical field
This utility model relates to a kind of sealing-plug, and the sealing-plug in particular for the double-layer vacuum blood taking tube mouth of pipe belongs to technical field of medical instruments.
Background technology
At medical field; Blood taking tube is used by a large amount of; Usually thrombotest adopts 1.8ml or 2.7ml blood taking tube all to be and the supporting standard vacuum blood taking tube of corresponding instrument such as centrifuge, and a large amount of spaces of not filled up by blood is arranged at the top of vacuum test tube, is called " dead space ".The suitable application macromole of the thrombotest pipe that domestic and international research shows to be had " dead space " heparin patient detects APTT, and " dead space " causes platelet activation, and the hyperamization platelet PF4 factor discharges, so cause the false shortening APTT time.Test shows that this error is the random phenomenon that can not expect, and the probability of appearance is approximately 15%～22%, because the false shortening APTT time causes doctor's mistake to increase the heparin consumption, thereby causes hemorrhage serious consequence.
In the reality, adopt the double-layer vacuum blood taking tube to avoid this phenomenon, pipe and outer tube in the double-layer vacuum blood taking tube is divided into; Interior pipe is inserted in the outer tube, and it is fixing to adopt glue to be connected with outer tube, then adopts plug and enclosing cover to come to manage and outer tube in the shutoff respectively to the sealing of double-layer vacuum blood taking tube; Adopt this sealing mechanism to come the inner and outer pipes of shutoff double-layer vacuum blood taking tube; Use extremely inconveniently, and plug and enclosing cover can not fully seal with the inner and outer pipes mouth of pipe of double-layer vacuum blood taking tube, and air-tightness is relatively poor.Therefore, be necessary existing double-layer vacuum rubber plug for vacutainer is improved.
The utility model content
The technical problem that this utility model will solve provides that a kind of puncture force is low, good airproof performance, the double-layer vacuum of the shutoff simultaneously blood taking tube inner and outer pipes mouth of pipe; And effectively blood sample is intercepted with extraneous, use the more convenient double-layer vacuum hemostix of operation to use sealing-plug simultaneously.
For solving the problems of the technologies described above, a kind of double-layer vacuum hemostix of this utility model is used sealing-plug, comprises cock body part and plug neck portion, it is characterized in that, said plug neck portion is made up of the first plug neck that is the ladder arrangement and the second plug neck.
Adopt said structure; Because the plug neck portion is divided into the first plug neck and the second plug neck; The first plug neck can with the outer tube wall tight fit of double-layer vacuum blood taking tube, play plug neck can with double-layer vacuum blood taking tube inner tube wall tight fit, first fills in neck, second fills in neck and is structure as a whole; The inner and outer pipes mouth of pipe of double-layer vacuum blood taking tube is fully sealed, and sealing property is better, and can effectively blood sample be intercepted with extraneous.
In order further to increase air-tightness; This utility model also can be made further improvement; Be provided with cannelure in top plug body portion and the said first plug neck junction, this cannelure can with the blood taking tube mouth of pipe inwardly slightly the bulge loop of microprotrusion firmly block, strengthen air-tightness with this.
In order accurately to block the pin position, and puncture part attenuation in the middle of making, use very little puncture force can make needle point thorn sealing-plug thoroughly, cock body part crown center is provided with inner groovy.
For further economical with materials, reduce cost, the bottom of the second plug neck caves inward.
In order to reduce the contact area of first plug neck and double-deck blood taking tube outer tube mouth of pipe inwall, so the resistance of reducing friction, make sealing-plug use operation more convenient, first fills in neck has tapering from top to down.
The beneficial effect of this utility model is: because the plug neck portion is divided into the first plug neck and the second plug neck; First the plug neck can with the outer tube wall tight fit of double-layer vacuum blood taking tube; Under fill in neck can with double-layer vacuum blood taking tube inner tube wall tight fit; The first plug neck, the second plug neck are structure as a whole, and the inner and outer pipes mouth of pipe of double-layer vacuum blood taking tube is fully sealed, and sealing property is better, and can effectively blood sample be intercepted with extraneous.Be provided with cannelure in top plug body portion and the said first plug neck junction, this cannelure can with the blood taking tube mouth of pipe inwardly slightly the bulge loop of microprotrusion firmly block, strengthen air-tightness with this.Cock body part crown center is provided with inner groovy, can accurately block the pin position, and puncture part attenuation in the middle of making, and uses very little puncture force can make the needle point thorn pass through sealing-plug.
Description of drawings
Fig. 1 is the generalized section of this utility model.
Among the figure: 1, cock body part; 2, the first plug neck; 3, the second plug neck; 4, groove; 5, cannelure.
The specific embodiment
Referring to Fig. 1, a kind of sealing-plug that is used for the double-layer vacuum hemostix mouth of pipe of this utility model comprises cock body part 1 and plug neck portion, and the double-deck blood taking tube outer tube nose end in said cock body part 1 edge is towards last extension; Said plug neck portion is made up of the first plug neck 2 and the second plug neck, 3 two parts; The first plug neck 2 and double-deck blood taking tube outer tube mouth of pipe inwall tight fit, the second plug neck 3 and the interior pipe of double-deck blood taking tube mouth of pipe inwall tight fit, the bottom of the second plug neck 3 caves inward.
On the basis of the foregoing description, be provided with cannelure 5 in cock body part 1 and the first plug neck, 2 junctions.And can be at the top be provided with an inner groovy 4 in the middle of the upper surface, and so just can guarantee the direction that punctures, can accurately block the pin position during use, and puncture part attenuation in the middle of making, use very little puncture force can make needle point sting sealing-plug thoroughly.
Be provided with cannelure in cock body part and the said first plug neck 2 junctions, this cannelure can with the blood taking tube mouth of pipe inwardly slightly the bulge loop of microprotrusion firmly block, strengthen air-tightness with this.The first plug neck 2 has tapering from top to down, so, not only reduces the contact area of the first plug neck 2 and double-deck blood taking tube outer tube mouth of pipe inwall, and then the resistance of reducing friction, and can make sealing-plug use operation more convenient.
The above-described just preferred implementation of this utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from this utility model know-why, can also make some improvement and retouching, these improvement and retouching also should be included within the protection domain of this utility model.
