Abstract
The utility model discloses a sealing plug for a tube opening of a hemostix, which comprises a plug body (1) and plug necks (2 and 3). The plug necks consist of an upper plug neck (2) and a lower plug neck (3), the upper plug neck (2) is in close fit with the inner wall of an outer tube of a double-layered vacuum blood collection tube, the lower plug neck (3) is in close fit with the inner wall of an inner tube of the blood collection tube. By the structure, the sealing plug for the tube opening of the blood settling hemostix is waterproof and airtight, and needed force for plugging the sealing plug in the tube opening and taking out the sealing plug from the tube opening is small. In addition, an inner groove (6) further can be arranged in the middle of the upper surface of the top of the sealing plug, a cam (7) which radially extends along the upper surface of the top of the sealing plug is arranged at the joint of the inner groove and the upper surface of the top of the sealing plug, so that puncture is easy, a puncturing direction of a needle is guaranteed, and production cost can be further saved.
Description
Technical field
This utility model relates to a kind of sealing-plug, and the sealing-plug in particular for the hemostix 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, does not reveal after collection in order to make blood sample, and is not contaminated, and the most basic way is with plug the blood sampling mouth of pipe to be sealed.At present, comprised plug face and plunger section by the rubber plug for vacutainer that extensively adopts, plug face top becomes plane, acupuncture part and condition of equivalent thickness on every side in the middle of making, and the increase venipuncture difficulty, plunger Duan Chengzhi neck shape can not fully to seal air-tightness relatively poor with the blood taking tube mouth of pipe.Therefore, be necessary existing 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, can effectively blood sample be intercepted with extraneous, and uses the sealing-plug of the more convenient heavy blood hemostix mouth of pipe of operation.
For solving the problems of the technologies described above, this utility model is a kind of be used to the to take a blood sample sealing-plug of the mouth of pipe comprises top plug body portion and following cock body part, wherein, said top plug body portion along the blood taking tube nose end towards last extension; The said part of cock body down is made up of plug neck and flank two parts; Plug neck and blood taking tube mouth of pipe inwall tight fit, flank and blood taking tube mouth of pipe outer wall tight fit; Have between said plug neck and the flank at interval.
Adopt said structure, because the cock body part is made up of plug neck and flank two parts down; Plug neck and blood taking tube mouth of pipe inwall tight fit, flank and blood taking tube mouth of pipe outer wall tight fit, this two-sided friction tight mode are compared to only uses plug neck single face and blood taking tube tight fit, and sealing property is better, ability can effectively intercept blood sample with the external world.
In order further to increase air-tightness, this utility model also can be made further improvement, is provided with groove in top plug body portion and said plug neck junction, and this groove can firmly block the bulge loop that the blood taking tube mouth of pipe inwardly omits microprotrusion, strengthens 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 the needle point thorn pass through sealing-plug, last cock body crown center is provided with inner groovy; The inner groovy edge is provided with flange, and the bottom surface of this inner groovy can be hemispherical or be total to its any solid geometry shape; And bottom said inner groovy, be provided with blind hole.
As the further improvement of this utility model, said flank is made up of the two parts that separate at least, adopts such structure; Can not only effectively seal the blood taking tube mouth of pipe; When inserting sealing-plug,, reduced contact area with blood taking tube mouth of pipe outer wall owing to be not overall structure; Reduced frictional force, need not much powers the sealing-plug and the blood taking tube mouth of pipe are sealed fully.Can effectively save production cost.
The beneficial effect of this utility model is: following cock body part is made up of plug neck and flank two parts; Plug neck and blood taking tube mouth of pipe inwall tight fit, flank and blood taking tube mouth of pipe outer wall tight fit, this two-sided friction tight mode are compared to only uses plug neck single face and blood taking tube tight fit, and sealing property is better, ability can effectively intercept blood sample with the external world.Be provided with groove in top plug body portion and said plug neck junction, this groove can with the blood taking tube mouth of pipe inwardly slightly the bulge loop of microprotrusion firmly block, strengthen air-tightness with this.Last cock body crown center is provided with inner groovy, and the inner groovy edge is provided with cam, and the bottom surface of this inner groovy can be hemispherical or be total to its any solid geometry shape; And bottom said inner groovy, be provided with blind hole, can accurately block the pin position, and puncture part attenuation in the middle of making, use very little puncture force can make the needle point thorn pass through sealing-plug.Flank is made up of the two parts that separate at least; Adopt such structure, can not only effectively seal the blood taking tube mouth of pipe, when inserting sealing-plug; Owing to be not overall structure; Reduced the contact area with blood taking tube mouth of pipe outer wall, reduced frictional force, need not much powers the sealing-plug and the blood taking tube mouth of pipe are sealed fully.
Description of drawings
Fig. 1 is the generalized section of this utility model;
Fig. 2 is that this utility model sealing-plug cooperates generalized section with blood taking tube.
Among the figure: 1, top plug body portion; 2, following cock body part; 3, plug neck; 4, flank; 5, groove; 6, inner groovy; 7, cam; 8, blind hole.
The specific embodiment
Referring to Fig. 1, a kind of sealing-plug that is used for the hemostix mouth of pipe of this utility model comprises top plug body portion 1 and following cock body part 2, said top plug body portion 1 along the blood taking tube nose end towards last extension; Said cock body part 2 down is made up of with flank 4 two parts plug neck 3; Plug neck 3 and blood taking tube mouth of pipe inwall tight fit, flank 4 and blood taking tube mouth of pipe outer wall tight fit; Have between said plug neck and the flank at interval.
On the basis of the foregoing description, be provided with groove 5 in top plug body portion and said plug neck junction, and can be provided with an inner groovy 6 in the middle of the upper surface at the top; This inner groovy 6 and upper surface junction, top are provided with along the top upper surface radially along the flange of stretching 7; Inner groovy 6 bottoms are provided with blind hole 8, 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 the needle point thorn pass through sealing-plug.
