The existing injector generally has only one cavity, if a plurality of different components are needed to be stored, and the components are needed to be mixed before injection. At present, common modes are that powder or liquid with different components are respectively stored through a plurality of containers, and then, before injection, the components of substances in the different containers are respectively sucked through a syringe to realize mixing.

Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the embodiments of the present application will be described in detail below with reference to the accompanying drawings. However, those of ordinary skill in the art will understand that in various embodiments of the present application, numerous technical details have been set forth in order to provide a better understanding of the present application. However, the claimed application may be practiced without these specific details and with various changes and modifications based on the following embodiments.

Example 1

A first embodiment of the application relates to a reservoir having a receiving space 1, as shown in fig. 1, and the receiving space 1 is provided with at least one breakable aperture-closing side 51 along a predetermined axis direction. The reservoir according to the present embodiment further includes: a breakable first barrier 2 and at least one breakable second barrier 3. Wherein the first barrier 2 is arranged at the closing side 51 as shown in fig. 1. Each second blocking member 3 is disposed in the accommodating space 1, and divides the accommodating space 1 into a plurality of cavities 11 along a predetermined axis direction.

As shown in fig. 1, the reservoir according to the present embodiment further includes: the pushing mechanism 4, the pushing mechanism 4 can slide along the preset axis direction in the accommodating space 1. The pushing mechanism 4 slides into the accommodating space 1 from the other side opposite to the closed side 51.

As can be seen from the above, since each second blocking member 3 is disposed in the accommodating space 1, the accommodating space 1 can be divided into a plurality of cavities 11 along the preset axis direction, and different liquid and/or powder can be stored through each cavity 11. Before injection, the first blocking member 2 and the second blocking members 3 may be pierced to conduct the cavities 11, and simultaneously, the liquid and/or powder stored in different cavities 11 may be mixed under the sliding action of the pushing mechanism, and finally, the mixed mixture may be pushed out to complete injection under the further sliding action of the pushing mechanism 4. It can be seen from this that the entire reservoir can be realized from mixing of the liquid and/or powder into injection in the reservoir, which is not only very convenient to operate, but also completely isolated from the outside, thus avoiding pollution of the liquid and/or powder during mixing by the outside environment.

Specifically, in some embodiments, as shown in fig. 1, when a plurality of second blocking members 3 may be provided, and each second blocking member 3 is sequentially arranged along a preset axis direction, so that two sides of each second blocking member 3 may form an independent cavity 11, and one powder and/or liquid may be stored through each independent cavity 11. In the present embodiment, as shown in fig. 2, only one second blocking member 3 is provided, so that the accommodating space 1 is divided into two cavities by the second blocking member 3, namely, a first cavity 11a and a second cavity 11b, and the pushing mechanism 4 is slidably disposed in the second cavity 11b along the preset axis direction, and meanwhile, the closed side 51 is disposed on a side of the first cavity 11a away from the second cavity 11b.

In addition, as shown in fig. 2, the reservoir of the present embodiment further includes: the container 5, and the container 5 has the accommodation space 1 along the preset axis direction, and at the same time, two sides of the container 5 along the preset axis direction are a closed side 51 and a pushing side 52, respectively. And, the first blocking member 2 is disposed on the closing side 51, and the pushing mechanism 4 slides into the second cavity 11b from the pushing side 52. When the powder or liquid stored in the first cavity 11a needs to be mixed with the powder or liquid stored in the second cavity 11b, the puncture outfit can be utilized first, the first barrier 2 and the second barrier 3 can be sequentially punctured by the puncture outfit, then the powder or liquid stored in the second cavity 11b can enter the first cavity 11a under the pushing of the pushing mechanism 4 by pushing the pushing mechanism 4, and the mixed mixture can be pushed out from the sealing side 51 by continuing pushing the pushing mechanism 4 after the two powder and/or liquid are mixed, so that the injection is completed. Because the whole liquid and/or powder is mixed in the storage device, the operation is simple and convenient, and the liquid and/or powder is completely isolated from the outside, so that the pollution of the outside environment to the two powders and/or liquid during mixing is avoided.

In the present embodiment, the first barrier member 2 and the second barrier member 3 may each be a septum member, and thus, the puncture device may be used to puncture the first barrier member and the second barrier member easily when the puncture device is used. Of course, in practical application, the two diaphragm members may not be pierced by a puncture device, but may directly push the pushing mechanism 4, so that the second cavity 11b may be continuously compressed under the pushing of the pushing mechanism 4, resulting in a rapid increase of the pressure in the second cavity 11b, and finally the second blocking member 3 may be destroyed under the action of pressure, so that the powder or liquid stored in the second cavity 11b may enter the first cavity 11a, be mixed with the powder or liquid in the first cavity 11a, and after the two powders and/or liquid are fully mixed, continue pushing the pushing mechanism 4 until the first blocking member 2 is destroyed under the action of pressure, so that the mixed mixture may be pushed out from the closed side 51, and injection is completed. In the present embodiment, the first separator 2 and the second separator 3 are described by taking a diaphragm as an example, but in actual use, rubber or plastic may be used for the first separator 2 and the second separator 3. In the present embodiment, however, the types of the first barrier 2 and the second barrier 3 are not particularly limited.

In addition, it should be noted that, in order to enable the pushing mechanism 4 to push the liquid or powder in the second cavity 11b into the first cavity 11a, the pushing mechanism 4 adopts a piston member, and a seal is formed between the piston member and the inner wall of the container 5, so that the liquid or powder in the second cavity 11b can be easily pushed into the first cavity 11a by the piston member. Meanwhile, in order to form sealing between the piston member and the inner wall of the container 5, a sealing ring can be sleeved on the piston member, so that flexible contact between the piston member and the inner wall of the container 5 can be realized, and the sealing performance of the piston member is ensured. Of course, in practical applications, the entire piston member may be made as a single flexible member, but in the present embodiment, there is no specific limitation on how the seal is formed between the piston member and the inner wall of the container 5.

Example two

The second embodiment of the present application is substantially identical to the first embodiment, with the main difference that in the first embodiment, both the first cavity 11a and the second cavity 11b are in the same container 5. In the present embodiment, however, the first cavity 11a and the second cavity 11b may be in different containers, i.e., as shown in fig. 3, the reservoir of the present embodiment further includes the first container 6 and the second container 7.

Wherein, the two sides of the first container 6 along the preset axis direction are respectively a closed side 61 and an open side 62, and the second container 7 is at least partially inserted into the first container 6 along the preset axis direction from the open side 62, and the second container 7 has a second cavity 11b along the preset axis direction, and meanwhile, one side of the second container 7 opposite to the closed side 61 is a discharging side 71, and one side far from the closed side 61 is a pushing side 72. In addition, as shown in fig. 3, a first cavity 11a is further formed between the closed side 61 of the first container 6 and the discharging side 71 of the second container 7, and the second blocking member 3 is disposed on the discharging side 71, and at the same time, the pushing mechanism 4 can slide into the second cavity 11b from the pushing side 72.

It can be seen from this that, in this embodiment, since the first cavity 11a and the second cavity 11b are respectively disposed in the first container 6 and the second container 7, and under the blocking effect of the second blocking member 3, the first cavity 11a and the second cavity 11b can respectively form independent cavities, thereby realizing storage of different powders or liquids. When the injection device is used, the first blocking piece 2 and the second blocking piece 3 can be pierced firstly, and then the pushing mechanism 4 is pushed, so that powder or liquid stored in the second cavity 11b can enter the first cavity 11a under the pushing of the pushing mechanism 4, and is mixed with the powder or liquid in the first cavity 11a, and after the two powder and/or liquid are mixed, the mixed mixture can be pushed out from the closed side 61 by continuously pushing the pushing mechanism 4, so that the injection is completed. Of course, in practical application, the mixing of the two solutions and/or powders, and the pushing after the mixing, may also be directly performed by pushing the pushing mechanism 4, so that the second barrier 3 and the first barrier 2 may be directly damaged under the action of pressure, in the same manner as in the first embodiment, and in this manner, the mixing of the two solutions and/or powders, and the pushing after the mixing may be similarly performed.

Also, as a preferred option, in some embodiments, as shown in fig. 3, the second container 7 is slidable with respect to the first container 6 along a preset axis direction, and when the second container 7 slides to the limit position in a direction toward the closing side 61, the discharging side 71 and the closing side 61 are separated from each other. It can thus be seen that by means of the sliding properties of the second container 7 in the first container 6, the volume of the first cavity 11a can be changed with the position of the second container 7 relative to the first container 6, so that the first cavity 11a can meet the storage requirements of liquid agents or powder agents of different quality, and by means of the sliding of the second container 7, the air in the first cavity 11a can be exhausted as much as possible before mixing two different powder agents and/or liquid agents, so that the air bubbles generated during mixing of the two liquid agents and/or powder agents can be reduced, the mixing effect of the two powder agents and/or liquid agents can be further improved, and the two liquid agents and/or powder agents can be fully mixed.

In order to limit the position of the second container 7 during sliding, as shown in fig. 3, the second container 7 is partially protruded around the preset axis direction to form a limit protrusion 73, and when the second container 7 slides to the limit position toward the closing side 61, the limit protrusion 73 may abut against the opening side 62 of the first container 6. By abutting the limiting protrusion 73 against the opening side 62, when the second container 7 slides to the limit position in the direction of the closed side 61, the discharging side 71 and the closed side 61 are still in a separated state, so that the phenomenon that the liquid or powder in the second cavity 11b is not pushed into the first cavity 11a and the liquid or powder in the first cavity 11a is pushed out from the closed side 61 by the second container 7 due to overlarge friction force between the pushing mechanism 4 and the second container 7 in the pushing process of the pushing mechanism 4 is avoided.

However, as an alternative, when the second container 7 is slidable relative to the first container 6 in the preset axial direction, as shown in fig. 4, the second container 7 may also be disposed entirely inside the first container 6, and in order to be able to mix the liquid or powder stored in the second cavity 11b with the liquid or powder stored in the first cavity 11a by the action of the pushing mechanism 4, and to generate a first frictional resistance with the first container when the second container 7 slides relative to the first container 6, and to mix and effect injection of the mixture; meanwhile, when the pushing mechanism 4 slides relative to the second container 7, a second friction resistance can be generated between the pushing mechanism and the second container 7, and the first friction resistance needs to be larger than the second friction resistance.

Therefore, in practical application, as shown in fig. 4, when the pushing mechanism 4 pushes the liquid or powder in the second cavity 11b from the discharging side 71 into the first cavity 11a, at this time, because the first friction resistance is greater than the second friction resistance, the second container 7 is not pushed by the pushing mechanism 4, so that the liquid or powder in the first cavity 11a is not pushed out from the closed side 61, and when the liquid or powder in the second cavity 11b is completely entered into the first cavity 11a under the action of the pushing mechanism 4, and after the liquid or powder stored in the first cavity 11a is completely mixed with the liquid or powder stored in the first cavity 11a, at this time, because the pushing mechanism 4 is already pushed against the discharging side 71 of the second container 7, by continuing to push the pushing mechanism 4, the pushing force of the pushing mechanism 4 can directly act on the second container 7, so as to overcome the first friction resistance generated between the second container 7 and the first container 6, push the second container 7 towards the closed side 61 of the first container 6, and then the mixture is pushed out from the closed side 61 of the first container 6.

In order to enable the second container 7 to slide with respect to the first container 6, the first frictional resistance is larger than the second frictional resistance, and as shown in fig. 4, the first seal ring 200 may be fitted to the second container 7, the second seal ring 300 may be fitted to the pushing mechanism 4, and the contact area between the first seal ring 200 and the inner wall of the first container 6 may be different from the contact area between the second seal ring 300 and the inner wall of the second container 7, for example: as shown in fig. 4, the number of the first sealing rings 200 may be increased to increase the contact area between the first sealing rings 200 and the inner wall of the first container 6, or the length of the first sealing member 200 may be increased to increase the contact area between the first sealing rings 200 and the inner wall of the first container 6, so that the first frictional resistance is ensured to be greater than the second frictional resistance by the difference of the contact areas. Of course, in practical application, the first seal ring 200 and the second seal ring 300 are made of different materials, and the first friction resistance can be made larger than the second friction resistance by the different materials.

Example III

A third embodiment of the present application relates to a reservoir, which is substantially the same as the second embodiment, and is mainly different in that in the present embodiment, as shown in fig. 5, two second blocking members 3 are provided, three chambers 11 are provided, and the first chamber 11a, the second chamber 11b, and the third chamber 11c are respectively provided along a predetermined axis direction. Meanwhile, the pushing mechanism 4 is slidably disposed in the third cavity 11c along the preset axis direction, and the closed side is disposed at a side of the first cavity 11a away from the second cavity 11b.

Specifically, as shown in fig. 5, the reservoir of the present embodiment further includes: a first container 10, a second container 20 and a third container 30. Wherein, two sides of the first container 10 along the preset axis direction are a closed side 101 and a first open side 102 respectively. Next, the second container 20 is inserted into the first container 10 at least partially from the first opening side 102 in the preset axis direction, and the side of the second container 20 opposite to the closing side 101 is the discharging side 201 of the breakable hole, while the side of the second container 20 away from the closing side 101 is the second opening side 202, and finally, the third container 30 is inserted into the second container 20 at least partially from the second opening side 202 in the preset axis direction, and the third container 30 has the third cavity 11c in the preset axis direction, and the side of the third container 30 opposite to the discharging side 201 is the extruding side 301 of the breakable hole, while the side of the third container 30 away from the extruding side 301 is the pushing side 302.

In addition, it is noted that as shown in fig. 5, a first cavity 11a is formed between the closed side 101 and the discharge side 201 of the first container 10, and a second cavity 11c is formed between the discharge side 201 and the extrusion side 301. And, one of the second blocking members 3 is disposed on the discharging side 201, and the other second blocking member 3 is disposed on the extruding side 301, and the pushing mechanism 4 slides into the third cavity 11c from the pushing side 302. In the present embodiment, as shown in fig. 5, the third container 30 is further slidable with respect to the second container 20 along the preset axis direction, and when the third container 30 slides with respect to the second container 20, a first frictional resistance is generated between the third container and the second container, and when the pushing mechanism 4 slides with respect to the third container 30, a second frictional resistance is generated between the third container 30, and at the same time, the first frictional resistance is larger than the second frictional resistance.

It will thus be seen that since the reservoir of the present embodiment includes the first, second and third chambers 11a, 11b and 11c, liquid or powder may be stored through the first, second and third chambers 11a, 11b and 11c, respectively. In practical application, when the pushing mechanism 4 pushes the liquid agent or powder in the third cavity 11c from the extrusion side 301 to the second cavity 11b, at this time, the pushing force of the pushing mechanism 4 can directly act on the third container 30 by continuing to push the pushing mechanism 4 because the first friction resistance is greater than the second friction resistance, so that the liquid agent or powder in the second cavity 11b can not be pushed out from the discharge side 201, and when the liquid agent or powder in the third cavity 11c is completely introduced into the second cavity 11b under the action of the pushing mechanism 4, and after the liquid agent or powder agent in the third cavity 11c is completely mixed with the liquid agent or powder stored in the second cavity 11b, the pushing mechanism 4 is already against the extrusion side 301 of the third container 30, the pushing force of the pushing mechanism 4 can directly act on the third container 30, so that the third container 30 can be pushed in the direction of the discharge side 201 of the second container 20 against the first friction resistance generated between the third container 30 and the second container 20, and the mixture in the second cavity 11b is not pushed out from the first cavity 201 to the first cavity 11a, and the mixture is finally pushed out from the first cavity 11a to the first cavity 101 a, and the mixture is finally mixed with the first cavity 11a is completely pushed out.

According to the above, the storage container of the embodiment can be used for storing, mixing and injecting 3 different powders or liquid agents, is very convenient to operate, and can be completely isolated from the outside, so that pollution to the liquid agents and/or the powders caused by the outside environment during mixing is avoided.

In order to enable the third container 30 to slide with respect to the second container 20, the first frictional resistance is larger than the second frictional resistance, and as shown in fig. 5, the third container 30 may be fitted with the first seal ring 200, the pushing mechanism 4 may be fitted with the second seal ring 300, and the contact area between the first seal ring 200 and the inner wall of the second container 20 may be different from the contact area between the second seal ring 300 and the inner wall of the third container 30, for example: as shown in fig. 5, the contact area between the first sealing ring 200 and the inner wall of the second container 20 may be increased by increasing the number of the first sealing rings 200, or the length of the first sealing member 200 may be increased to increase the contact area between the first sealing ring 200 and the inner wall of the second container 20, so that the first frictional resistance is ensured to be greater than the second frictional resistance by the difference of the contact areas. Of course, in practical application, the first seal ring 200 and the second seal ring 300 are made of different materials, and the first friction resistance can be made larger than the second friction resistance by the different materials.

Example IV

A fourth embodiment of the present application relates to a reservoir, and the third embodiment is a further improvement over the first and second embodiments, and the main improvement is that, as shown in fig. 6, the reservoir of the present embodiment further includes: a first spacer assembly 8 and a second spacer assembly 9.

As shown in fig. 6, the first partition member 8 is disposed in the first cavity 11a along a preset axis direction, and the first partition member 8 may partition the first cavity 11a into a plurality of first channels 111. The second partition member 9 is disposed in the second cavity 11b along the predetermined axis direction, and the second partition member 9 may partition the second cavity 11b into a plurality of second channels 112.

In this embodiment, as shown in fig. 6, the number of first channels 111 is the same as the number of second channels 112, and the first channels 111 and the second channels 112 are arranged along the preset axis direction.

In addition, as shown in fig. 6, the pushing mechanism 4 includes, for each second channel 112: the piston members 41 are disposed in the second passages 112, and each piston member 41 is slidable along a predetermined axis direction.

As can be seen from the above, the first cavity 11a is divided into a plurality of first passages 111 along the preset axis direction by the first partition member 8; meanwhile, the second cavity 11b is divided into a plurality of second channels 112 along the preset axial direction by the second separation assembly 9, and the number of the first channels 111 is the same as that of the second channels 112 and is uniquely and correspondingly arranged, so that the storage container of the embodiment can meet the storage of more liquid or powder. Meanwhile, the pushing mechanism 4 further comprises a piston member 41 disposed in each second channel corresponding to each second channel 112, and the reservoir of the present embodiment can further achieve mixing of multiple mixtures and separate injection of multiple mixtures through each piston member 41.

Specifically, in the present embodiment, as shown in fig. 6, the first partitioning member 8 includes: at least one first partition board 81 is disposed in the first cavity 11a, and when the first partition boards 81 are provided with a plurality of first partition boards, the first partition boards 81 are disposed in parallel, the first cavity 11a can be separated into a plurality of first channels 111 by one or more first partition boards 81, and liquid or powder can be disposed in each first channel 111. Similarly, the second partition member 9 includes, for each first partition 81: at least one second partition board 91 is disposed in the second cavity 11b, and when the second partition boards 91 are provided with a plurality of second partition boards, the second partition boards 91 are disposed in parallel, the second cavity 11b can be separated into a plurality of second channels 112 by one or more second partition boards 91, and liquid or powder can be disposed in each second channel 112. Meanwhile, the first blocking member 2 corresponds to each first channel 111 to form an independent first sealing portion 21, and similarly, the second blocking member 3 corresponds to each second channel 112 to form an independent second sealing portion 31. Therefore, in practical application, if powder and/or liquid in any only corresponding first channel 111 and second channel 112 need to be mixed, the corresponding first sealing part 21 and second sealing part 31 can be pierced by the piercer first, so that the only corresponding first channel 111 and second channel can be communicated, then the corresponding piston member 41 is pushed, the liquid and/or powder stored in the second channel 112 can be pushed into the only corresponding first channel 111, so that mixing of the two liquid and/or powder is realized, finally, the piston member 41 is pushed further, and the mixed mixture is pushed out from the first channel 111, so that injection is completed.

Example five

A fifth embodiment of the application relates to a reservoir assembly, as shown in fig. 7 and 8, comprising: the reservoir of the first, second, or third embodiment, further comprising: puncture outfit 100. The puncture outfit 100 may be used to puncture the first barrier 2 and each of the second barriers 3 in a predetermined axial direction.

As can be seen from the above, in practical application, the puncture outfit 100 is utilized to puncture the first barrier 2 and the second barrier 3, and then push the pushing mechanism 4, so that the powder or liquid stored in the second cavity 11b can enter the first cavity 11a under the pushing of the pushing mechanism 4, be mixed with the powder or liquid in the first cavity 11a, and after the two powders and/or liquid are mixed, the mixed mixture can be pushed out from the discharging side 51 by continuing to push the pushing mechanism 4, thereby completing injection. It can be seen from this that the entire reservoir can be realized from mixing of the liquid and/or powder into injection in the reservoir, which is not only very convenient to operate, but also completely isolated from the outside, thus avoiding pollution of the liquid and/or powder during mixing by the outside environment.

It will be understood by those of ordinary skill in the art that the foregoing embodiments are specific embodiments in which the application is practiced and that various changes in form and details may be made therein without departing from the spirit and scope of the application.
