Description

Bottle inner suction pipe, bottle cap assembly and reagent bottle

Technical Field

The utility model relates to the technical field of medical instruments, in particular to an in-bottle straw, a bottle cap assembly with the in-bottle straw and a reagent bottle with the bottle cap assembly.

Background

In the medical apparatus industry, IVD (in vitro diagnostic products, which is translated into in vitro diagnostic products in Chinese) is the largest market, and most of measurement principles of IVD products use reagents, namely one reagent or two reagents and four or five reagents. Therefore, there must be a reagent bottle carrying the reagent, and a suction device for sucking the reagent in the bottle.

Generally, an in-bottle suction tube is arranged on the inner side of a bottle cap of a reagent bottle and is used for sucking a reagent in the bottle; an outer bottle suction pipe is arranged on the outer side of the bottle cap of the reagent bottle and is used for being connected with an outer suction device.

In order to ensure that the reagent in the reagent bottle is fully used and has little residue, the following schemes can be selected for the in-bottle tube at present:

a) the inner suction pipe of the bottle uses a hose, and the tail end of the hose is connected with a heavy hammer structure;

b) the hard tube with certain strength is directly used and placed into the reagent bottle, and the size is controlled to ensure that the bottom of the hard tube is close to the bottom of the reagent bottle to the maximum extent.

The bottle inner suction pipe made of a hose material or a hard tube material is generally cut by a long tubular element for manufacturing. Therefore, the in-bottle suction pipe is generally a straight pipe with a uniform cross section.

In summary, the in-bottle straw has the following characteristics:

a) the inner bottle suction tube made of the hose material has certain elasticity, can be stretched and bent, and the inner diameter of the inner bottle suction tube can be set to be thinner so as to ensure that the inner bottle suction tube can be sucked when the reagent amount in the bottle is less. However, in order to ensure that the suction end of the hose is always positioned at the bottom of the bottle, the hose is generally used in combination with a heavy hammer, and therefore, the manufacturing cost of the internal suction pipe of the bottle with the structure is high. Moreover, since the weight structure is generally in the shape of a spherical block and can freely roll in the bottle, it is difficult to ensure that the suction port of the weight structure is completely attached to the bottom of the bottle, thereby causing reagent residue. When the hose is not matched with a heavy hammer for use, the surplus length is generally arranged at the bottom of the bottle to be bent so as to reduce the reagent residue, but along with the increase of the length, the reverse removal of bubbles in the hose into the bottle is more difficult, and the bubbles are easy to accumulate in a pipeline so as to influence the subsequent detection process.

b) The inner suction pipe of the bottle made of the hard pipe material has small elasticity, can not be stretched and is a straight pipe with a uniform cross section; and because the liquid pipe joint used for installing the internal suction pipe of the bottle on the bottle cap is made of plastic materials, the cross section of the liquid pipe joint is generally thicker, so that the internal diameter of the internal suction pipe of the bottle made of hard pipe materials is generally larger. The larger the inner diameter of the straw in the bottle is, the larger the residual amount of the reagent in the reagent bottle is.

The reason why the cross section of the liquid pipe joint on the bottle cap is thick is as follows: firstly, in order to ensure that the flow rate is proper when the reagent is sucked, certain requirements are made on the aperture of a liquid circulation hole of a bottle cap; secondly, because the bottle lid is mostly the injection molding, from the bottle lid manufacturing aspect, in order to satisfy the mobility requirement of moulding plastics, the liquid pipe connector on the bottle lid can not be done the undersize.

Detailed Description

The utility model discloses a bottle internal suction pipe, a bottle cap assembly and a reagent bottle, which can ensure that a suction device sucks a reagent at the bottom of the reagent bottle, reduce reagent residues and reduce reagent cost.

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, fig. 2 and fig. 6, the in-bottle tube provided in the embodiment of the present invention includes a soft pipette 31 and a hard support tube 32, and the hard support tube 32 is sleeved outside the soft pipette 31.

In the production process, manufacturers manufacture or purchase the straw raw material, then cut the straw raw material according to the size of the bottle body, and finally obtain the finished product of the in-bottle straw with proper length. The in-bottle straw claimed in the present invention may refer to a finished product of a single in-bottle straw having a size adapted to a specific bottle body, i.e., reference numeral 3 in fig. 6 and 7; or the straw raw material before cutting. That is, whether the finished product of the straw in the single bottle with the size matched with the specific bottle body or the raw material of the straw before cutting are all called the straw in the bottle, which is all within the protection scope of the utility model.

For convenience of understanding and explanation, the following description and specific analysis will be made by taking a finished product of a single in-bottle straw adapted to a specific bottle body as an in-bottle straw (see, in particular, reference numeral 3 in fig. 6 and 7), and taking a reagent bottle as a bottle body to which the in-bottle straw is mounted (see, in particular, reference numeral 6 in fig. 7).

The in-bottle straw 3 provided by the embodiment of the utility model has the advantages of simple structure and low production cost, and has the following ingenious points:

the inner diameter of the suction tube in the bottle can be made smaller by the flexible pipette 31;

the hard support tube 32 is sleeved outside the soft pipette 31, so that the inner bottle suction tube can be always kept in a vertical state with the bottom of the bottle after being installed in a reagent bottle, and the length of the hard support tube 32 is controlled, so that a small gap is reserved between the liquid suction end of the inner bottle suction tube and the bottom of a reagent bottle body, reagents in the reagent bottle can be fully sucked, the residue and waste of the reagents are reduced, the reagent loading is reduced, and the reagent cost is reduced.

Further, referring to fig. 3 and 4, the side wall of the connecting portion of the rigid support tube 32 for connecting with the bottle cap is provided with a glue passing hole 321 for accommodating the solid glue block 5. Specifically, a plurality of glue holes 321 (e.g., two, three, or four) may be formed in the rigid support tube 32 along the circumferential direction, or only one glue hole 321 may be formed, as long as the purpose of filling glue is achieved, and the connection strength of the rigid support tube 32 is not affected. Therefore, when the hard support tube 32 is mounted on the bottle cap mounting seat 2, not only the hard support tube 32 is mounted through the first joint 21, but also the hard support tube 32 is bonded through the solid glue block 5 (which is in a liquid state or a paste state during the coating process and then automatically cured into a solid state, so that the solid glue block is called as a "solid glue block"), and moreover, since part of the solid glue block 5 is filled in the glue through hole 321, a buckling effect can be formed after the solid glue block 5 is cured, which is helpful for firmly fixing the hard support tube 32 and the bottle cap mounting seat 2 together.

Further, referring to fig. 1, 3 and 7, the end of the bottle inner tube 3 away from the bottle cap mounting base 2 (i.e., the liquid suction end) is provided with a chamfered notch. This scarf can effectively prevent to take place the problem that the imbibition is not smooth and easy when the bottom contact of the bottom that leads to straw 3 in the bottle and reagent bottle body 6 is too tight because of part manufacturing and assembly error, and moreover, this scarf can be favorable to guaranteeing that the reagent residue in the reagent bottle is few, saves the reagent cost.

In addition, the embodiment of the utility model also provides a bottle cap assembly, which comprises a connecting part 1 matched with the bottle mouth, a mounting seat 2 arranged on the connecting part 1, and the in-bottle straw 3. Please refer to fig. 1, fig. 2, fig. 5, and fig. 6, in combination with fig. 7:

the connecting part 1 is an annular structure used for being connected with a bottle mouth;

the mounting seat 2 is arranged on the connecting part 1 and used for mounting the in-bottle suction pipe 3, a liquid flow hole penetrating through the inner side and the outer side (the inner side refers to the side surface of the mounting seat 2 in the bottle after the bottle cap assembly and the bottle body are assembled, and the outer side refers to the side surface of the mounting seat 2 outside the bottle after the bottle cap assembly and the bottle body are assembled) is arranged in the mounting seat 2, and the in-bottle suction pipe 3 is communicated with the liquid flow hole.

It can be seen that the bottle cap assembly employs the in-bottle straw 3 described above. Therefore, the inner diameter of the vial-inside tube can be made small by the flexible pipette 31. Moreover, in this bottle cap subassembly, because stereoplasm stay tube 32 is the hard tube that has the compatible material of reagent to can ensure that bottle cap subassembly can make the interior pipe 3 of bottle keep the vertical state all the time when assembling on bottle 6, and, through the length of control stereoplasm stay tube 32, can ensure to have less clearance between the imbibition end of the interior pipe 3 of bottle and the bottle bottom, even directly offset with the bottle bottom inboard, so as to ensure to fully absorb the reagent in the reagent bottle through the interior pipe 3 of bottle, reduce the residue and the waste of reagent, thereby reduce reagent loading, reduce cost.

Specifically, referring to fig. 1 and 2, in the bottle cap assembly, a first connector 21 for inserting the bottle internal suction pipe 3 is disposed on a side of the mounting seat 2 facing the inside of the bottle, and the liquid flow hole is disposed in the first connector 21. After assembly, the connecting end of the bottle cap suction pipe 3 is connected with the first connector 21, and the other end of the bottle cap suction pipe is a liquid suction end and used for extending to the bottom of the bottle to absorb the reagent in the bottle.

When the bottle inner suction pipe 3 is inserted into the first joint 21, the connecting end of the soft liquid suction pipe 31 and the connecting end of the hard support pipe 32 are sequentially sleeved on the first joint 21 from inside to outside. It should be noted here that the connecting end of the hard support tube 32 is sleeved outside the connecting end of the soft pipette 31, and is tightly fitted with the connecting end, but basically does not deform; when the connection end of the soft pipette 31 is sleeved on the first joint 21, the inner diameter is enlarged by the first joint 21, and the thickness of the pipe wall is reduced, so that the soft pipette is tightly matched with the first joint 21, or is in interference fit with the first joint.

However, the present invention is not limited to this, and in other embodiments, only the connecting end of the rigid support tube 32 may be sleeved on the first joint 21, and the two may be fixed to each other by inserting.

Specifically, referring to fig. 5, a first groove 23 is disposed around the first joint 21 on the inner side of the mounting seat 2 (i.e., the side of the mounting seat 2 facing the inside of the bottle), so that a first annular gap is formed between the side wall of the first joint 21 and the side wall of the first groove 23, and the internal bottle straw 3 is fastened and fixed through the first annular gap. That is to say, with bottle interior straw 3 plug to first joint 21 on the back, not only first joint 21 can play the positioning action to bottle interior straw 3, moreover, the lateral wall of first recess 23 also can play certain limiting displacement to bottle interior straw 3, avoids bottle interior straw 3 to drop because of excessively rocking or slope.

Further, the solid rubber block 5 is filled between the connecting portion of the bottle internal suction pipe 3 inserted in the first joint 21 and the outer annular wall of the first annular gap, and the position of the hard support pipe 32 coated with the solid rubber block 5 is provided with the rubber hole 321, and the rubber hole 321 is used for forming a buckle connection effect with the solid rubber block 5, so that the bottle internal suction pipe 3 is more firmly and fixedly connected with the bottle cap mounting seat 2.

Specifically, the first groove 23 is a circular ring-shaped groove, the first annular gap is a circular ring-shaped gap, and after the in-bottle suction pipe 3 is inserted into the first joint 21, the thickness of a radial cavity of the circular ring-shaped gap is greater than the thickness of a pipe wall of the in-bottle suction pipe 3, so as to fill the solid glue block 5. That is to say, in the assembling process, after the bottle internal suction pipe 3 is inserted to the first joint 21, a glue filling gap is formed between the outer pipe wall of the bottle internal suction pipe 3 and the side wall of the first groove 23, so that the connection strength between the bottle internal suction pipe 3 and the bottle cap mounting seat can be enhanced through the solid glue block 5.

In addition, in other embodiments, the cross section of the first groove 23 can be designed to be rectangular, oval or other polygonal shapes, which can also achieve the above-mentioned purpose of filling glue. Therefore, the shape of the first groove 23 is not particularly limited in the present invention.

Specifically, referring to fig. 5, the outer side of the mounting base 2 (i.e. the side of the mounting base 2 facing the outside of the bottle) is provided with a second connector 22 for inserting the outer suction tube 4 of the bottle, and a second groove 24 surrounding the second connector 22. Wherein: the central hole of the first joint 21 and the central hole of the second joint 22 are communicated to form a liquid circulation hole (namely a liquid flow hole) for circulating a reagent in the connecting seat 2; a second annular gap is formed between the side wall of the second connector 22 and the side wall of the second groove 24 so as to facilitate the insertion of the outer bottle straw 4.

Specifically, referring to fig. 1, 2 and 6, in the above-mentioned cap assembly, the external bottle suction pipe 4 and the soft suction pipe 31 are two hose segments respectively, and are respectively inserted outside the second joint 22 and outside the first joint 21. Preferably, the off-vial pipette 4 and flexible pipette 31 are small inner diameter hoses of equal or close length to ensure that the volume in the tube is small, thereby helping the reagent aspiration power source (e.g., syringe) to eliminate air bubbles from the instrument tube and provide clean, bubble-free reagent for other measurement components. That is to say, the cooperation is used with corresponding syringe, can effectively push the bubble in the pipe in the reagent bottle, reduces the accumulation of bubble in the pipeline, for other modules of complete machine provide clean reagent, promotes the accuracy and the stability of complete machine performance.

Alternatively, in other embodiments, the external bottle suction pipe 4 and the soft liquid suction pipe 31 may be the same flexible pipe inserted in the liquid flow hole inside the mounting seat 2, that is, a flexible pipe passing through the liquid flow hole to penetrate the inside and outside of the mounting seat 2, the portion of the flexible pipe outside the bottle being the external bottle suction pipe 4, and the portion inside the bottle being the soft liquid suction pipe 31. The scheme can also achieve the aim of reducing bubbles in the suction pipe.

Specifically, referring to fig. 1, in the bottle cap assembly, the annular connecting portion 1 is provided with an internal thread adapted to an external thread of the bottle mouth; the mounting seat 2 is fixedly connected in a central hole at one end of the annular connecting part 1, and the top end of the mounting seat 2 protrudes out of the central hole of the annular connecting part 1; the bottom periphery of the mounting seat 2 is provided with a first radial clamping edge 25 extending outwards along the radial direction, a second radial clamping edge 11 extending inwards along the radial direction is arranged in the center hole of the top of the annular connecting part 1, and the first radial clamping edge 25 is axially clamped with the second radial clamping edge 11.

The connecting part 1 is a plastic shell or a metal shell so as to be fixedly connected with the bottle body.

Finally, referring to fig. 7, the embodiment of the present invention further provides a reagent bottle, which includes a bottle body 6, and the above-mentioned bottle cap assembly. Wherein, the connecting end of the bottle inner suction pipe 3 in the bottle cap component is connected with the first joint 21 at the inner side of the bottle cap mounting seat 2; the other end of the bottle inner suction pipe 3 is a liquid suction end which is propped against the inner side of the bottle bottom so as to absorb the reagent in the bottle to the maximum extent.

To sum up, the bottle cap assembly provided by the embodiment of the utility model has the following assembly mode:

the bottle outer suction pipe 4 is a hose, one end of the hose is connected to the second connector 22 on the outer side of the bottle cap mounting seat 2 in an interference manner, and the other end of the hose is connected to the whole machine through a luer connector;
