[0014] When the air pressure in the second accommodating chamber is greater than a preset value, the gravity valve is opened; when the air pressure in the first accommodating chamber is less than or equal to the preset value, the gravity valve is closed.

[0015] In one embodiment, the reactant assembly includes a first reactant, a conductive member, and a second reactant arranged in sequence from the second accommodating chamber toward one side of the first accommodating chamber;

Figure 2 A schematic diagram of a driving device provided in another embodiment of the present application is shown. Figure 3 A schematic diagram of a driving device provided in yet another embodiment of the present application is shown.

Figure 6 A schematic diagram of a driving device provided in another embodiment of the present application is shown.

[0044] The driving device provided in one embodiment of the present application includes a body 100, a moving part 200 and a driving circuit 300. The body 100 is configured with a accommodating chamber 110; the moving part 200 is accommodated in the accommodating chamber 110, and the accommodating chamber 110 is divided into a first accommodating chamber 111 and a second accommodating chamber 112; the first accommodating chamber 111 is used to accommodate the pre-loaded material 800, and the second accommodating chamber 112 is used to accommodate the reactant component 900, and the first accommodating chamber 111 is configured with an opening 1111; the driving circuit 300 is connected to the reactant component 900, and the driving circuit 300 can turn on the reactant component 900; when the reactant component 900 is turned on, a reaction can occur and generate gas to push at least part of the moving part 200 to move from the second accommodating chamber 112 toward one side of the first accommodating chamber 111. Specifically, the direction of the second accommodating chamber 112 toward the first accommodating chamber 111 is Figure 1-Figure 4The direction from x′ to x is such that the pre-packed material 800 flows out from the opening 1111 .

[0045] When the above-mentioned drive device is installed on the insulin pump, the pre-loaded material 800 is insulin. Now, this drive device is used as a power source to push insulin. Specifically, the user controls the drive circuit 300 so that the drive circuit 300 can selectively conduct the reactant assembly 900, thereby realizing whether insulin is pushed. When it is necessary to push insulin, the drive circuit 300 conducts the reactant assembly 900, and the reactant assembly 900 can react and produce gas, and the gas pushes the moving part 200 to move from the second accommodating chamber 112 toward the side of the first accommodating chamber 111, so that the pre-loaded material 800, that is, insulin, flows out from the opening 1111 of the first accommodating chamber 111 to the subcutaneous part of the user. And when it is not necessary to push insulin, the drive circuit 300 is controlled not to conduct the reactant assembly 900.

[0046] When the drive device is used as a power source for pushing insulin, the movement of the movable part 200 is achieved by controlling the reactant component 900 to react and generate gas. Therefore, the power source used by the entire device is to generate gas through the reaction of the reactant component 900 to achieve propulsion. Therefore, compared with installing a precision motor, the entire device only requires the reactant component 900 and a second accommodating chamber 112 for accommodating the reactant component 900 on the body 100. Therefore, the cost of the entire device is lower, thereby making the user's use cost lower; and the structure is simpler, the size is smaller, and the user is more convenient to wear it.

[0047] It should be noted that the reactant component 900 can be a component that can generate gas after heating. For example, a heating wire and a hydrogen peroxide solution, a heating wire and an ammonia solution, a heating wire and an ethanol solution, a heating wire and a mixture of potassium chlorate and a manganese dioxide catalyst, or a heating wire and sodium nitrate. By arranging a heating wire in these solutions or solids, the heating wire generates heat under the action of the power supply of the drive circuit 300, thereby increasing the temperature of these solutions or solids, so that these solutions or solids decompose or volatilize after being heated to generate more gas, so as to push the moving part 200 along the Figure 1-Figure 4 Move from x' to x direction.

[0048] Of course, the reactant component 900 can also be any one of a mixture of hydrogen peroxide solution and catalyst manganese dioxide, sodium bicarbonate powder and acetic acid, sodium carbonate solution and aluminum sulfate, water and sodium nitrite solid and zinc powder and a capillary membrane. There is no special limitation on this. It only needs to be able to generate gas under certain conditions and drive the moving part 200 to move.

[0049] It should be noted that the driving circuit 300 conducts the reactant assembly 900 and specifically refers to that the reactant assembly 900 is energized by the driving circuit 300, so that some reactants in the reactant assembly 900 can react under the effect of energization, thereby generating gas. For example, when the reactant assembly 900 is a heating wire and a component (hydrogen peroxide solution, ammonia solution, ethanol solution, a mixture of potassium chlorate and manganese dioxide catalyst, sodium nitrate) that can generate gas after heating, when the heating wire is energized, the heating wire generates heat and transfers heat to the component that can generate gas after heating. Or when the reactant assembly 900 is any one of a mixture of hydrogen peroxide solution and catalyst manganese dioxide, sodium bicarbonate powder and acetic acid, sodium carbonate solution and aluminum sulfate, water and sodium nitrite solid and zinc powder and a capillary diaphragm, when the capillary diaphragm is energized, the above two reactants can contact and generate gas through the electrowetting effect of the capillary diaphragm.

[0050] It should be noted that the drive device can be applied not only to insulin pumps, but also to any other device that needs to push liquid or solid, without any special limitation. The following is only for the case where the drive device is applied to an insulin pump and the pre-loaded material 800 is insulin.

[0051] See also Figure 1-Figure 4 In some specific embodiments, the moving member 200 may be an airbag. When the reactant assembly 900 reacts and generates gas, the airbag can be expanded and deformed, so that the front end of the airbag close to the first accommodating cavity 111 can move along the Figure 1-Figure 4 The airbag moves in the direction from x' to x, so that the insulin in the first accommodating cavity 111 flows out from the opening 1111 under the compression of the airbag under expansion deformation.

[0052] In another specific embodiment, the moving member 200 may also be a deformable diaphragm. When the reactant assembly 900 reacts and generates gas, the deformable diaphragm can expand and deform, thereby allowing the front end of the deformable diaphragm close to the first accommodating cavity 111 to move along the first accommodating cavity 111. Figure 1-Figure 4 The first accommodating chamber 111 moves in the direction from x' to x, so that the insulin in the first accommodating chamber 111 flows out from the opening 1111 under the pressure of the deformable diaphragm under expansion deformation. Specifically, the deformable diaphragm can be PTFE (polytetrafluoroethylene), EPDM (ethylene propylene diene monomer), FKM (fluororubber), NBR (nitrile butadiene rubber), NR (natural rubber), SI (silicone rubber), IIR (butyl rubber), etc.

[0053] See also Figure 6In another embodiment, the moving member 200 is a piston 210 and an elastic member 220. When the reactant assembly 900 reacts and generates gas, the front end of the piston 210 can move along the Figure 1-Figure 4 The piston 210 moves in the direction from x' to x, thereby causing the insulin in the first accommodating chamber 111 to flow out from the opening 1111. When the reactant assembly 900 stops reacting to generate gas, the piston 210 can move along the elastic force of the elastic member 220. Figure 1-Figure 4 Move from x to x' in the direction of the axis, thereby returning to the corresponding preset position.

[0054] The following is a detailed description of the structure of the drive device. Figure 1-Figure 4 and Figure 6 The driving device provided in some embodiments of the present application further includes a waterproof breathable membrane 400, which is disposed on the side of the moving part 200 away from the first accommodating chamber 111. By providing the waterproof breathable membrane 400, when the reactant assembly 900 reacts and generates gas in the second accommodating chamber 112 under the conduction of the driving circuit 300, the waterproof breathable membrane 400 can only allow the gas to pass through, thereby pushing the moving part 200 to move. Liquid will not pass through the waterproof breathable membrane 400, thereby preventing the liquid from entering the first accommodating chamber 111 from the matching point between the moving part 200 and the cavity wall of the first accommodating chamber 111, thereby contaminating insulin, making the entire device safer to use.

[0055] See also Figure 1-Figure 2 and Figure 6 , the reactant assembly 900 of the driving device provided in some embodiments of the present application includes a first reactant 910 and a conductive member 920; the conductive member 920 is connected to the driving circuit 300, and the driving circuit 300 can conduct the conductive member 920; when the conductive member 920 is conducted, the first reactant 910 can react and generate gas. By setting the reactant assembly 900 as the first reactant 910 and the conductive member 920, it is controlled by controlling the conductive member 920 to control whether the first reactant 910 can react and generate gas. For example, when the conductive member 920 is a heating wire, the first reactant 910 is any one of a hydrogen peroxide solution, an ammonia solution, an ethanol solution, a mixture of potassium chlorate and a manganese dioxide catalyst, and sodium nitrate. When the driving circuit 300 conducts the heating wire, the heating wire heats up, and then the first reactant 910 is decomposed or vaporized in a heated state, thereby generating gas.

[0056] It should be noted that when the conductive member 920 is a heating wire, according to Joule's law, the heat generated by the current passing through the heating wire is proportional to the square of the current, proportional to the resistance of the heating wire, and proportional to the time of power on. Therefore, the current passing through the heating wire or the time of the current passing through the heating wire can be controlled by the driving circuit 300, or the heating wire can be set as an adjustable resistor, and the resistance value of the adjustable resistor connected to the driving circuit 300 can be changed to change the heat generated by the conductive member 920, thereby controlling the reaction rate of the first reactant 910.

[0057] For example, when a large dose of insulin contained in the first accommodating chamber 111 is required to be injected, the user controls the current flowing through the heating wire to be larger through the driving circuit 300, or the current flowing through the heating wire for a longer time, or increases the resistance of the heating wire connected to the driving circuit 300, so that the heating wire generates more heat, thereby increasing the volume of the gas generated by the first reactant 910, and pushing the moving part 200 along the Figure 1-Figure 4 The distance moved from x' toward x is greater, so that the volume of insulin flowing out from the opening 1111 is greater, thereby achieving the control of the temperature of the heating wire and ultimately achieving the adjustment of the infusion speed.

[0058] When a small dose of insulin contained in the first accommodating chamber 111 is required to be injected, the user controls the current flowing through the heating wire to be a smaller current through the driving circuit 300, or the time for the current flowing through the heating wire to be shorter, or the resistance of the heating wire connected to the driving circuit 300 is reduced, so that the heat generated by the heating wire is smaller, and the volume of the gas generated by the first reactant 910 is smaller, pushing the moving part 200 along the Figure 1-Figure 4 The distance moved from x' toward x is smaller, so that the volume of insulin flowing out from the opening 1111 is smaller, thereby achieving the control of the temperature of the heating wire and ultimately achieving the adjustment of the infusion speed.

[0059] In one specific embodiment, the conducting member 920 is a heating wire, the first reactant 910 is a hydrogen peroxide solution, and the heating wire is immersed in the hydrogen peroxide solution. When the heating wire is powered on and generates current under the control of the driving circuit 300, the heating wire generates heat according to Joule's law, and the hydrogen peroxide solution decomposes relatively quickly under the heating effect of the heating wire to produce oxygen and water. The oxygen passes through the waterproof breathable membrane 400 and pushes the moving member 200 to move, thereby realizing the outflow of insulin from the opening 1111 to achieve the push injection of insulin.

[0060] See also Figure 1-Figure 2 and Figure 6The driving device of the driving device provided in some embodiments of the present application further includes a pressure sensor 500, which is installed in the second accommodating chamber 112. The pressure sensor 500 is electrically connected to the driving circuit 300, and the pressure sensor 500 is used to detect the rate of change of the air pressure in the second accommodating chamber 112. By arranging the pressure sensor 500 on the side of the second accommodating chamber 112 close to the first accommodating chamber 111, when the reactant assembly 900 reacts to generate gas, the rate of change of the air pressure in the second accommodating chamber 112 can be monitored in real time through the pressure sensor 500, so that the user can know the change of the air pressure in real time, avoid the air pressure in the second accommodating chamber 112 from changing too fast in a short time, and be safer and more reliable.

[0061] In one embodiment, the driving circuit 300 is used to trigger the action of stopping the conduction of the reactant assembly 900 when the rate of change of the air pressure in the second accommodating chamber 112 is greater than a preset threshold. When the rate of change of the air pressure in the second accommodating chamber 112 is greater than the preset threshold, the driving circuit 300 triggers the action of stopping the conduction of the reactant assembly 900, so that the reactant assembly 900 no longer reacts and produces gas, so as to prevent the further increase of the rate of change of the air pressure, which is safer. It should be noted that there is no restriction on the numerical value of the preset threshold, which can be selectively set according to actual use.

[0062] See also Figure 1-Figure 2 and Figure 6 , the driving device provided in some embodiments of the present application also includes a gravity valve 600, which is installed on the side wall of the first accommodating chamber 111; when the air pressure in the second accommodating chamber 112 is greater than a preset value, the gravity valve 600 opens; when the air pressure in the first accommodating chamber 111 is less than or equal to the preset value, the gravity valve 600 closes. By setting the gravity valve 600, when the air pressure in the second accommodating chamber 112 is greater than the preset value, the gravity valve 600 can automatically open and perform exhaust operation, so that the air pressure in the second accommodating chamber 112 will not be too high, and the use of the entire driving device is safer. It should be noted that there is no restriction on the numerical value of the preset value, which can be selectively set according to actual usage.

[0063] In one embodiment, when the air pressure in the second accommodating chamber 112 gradually increases to overcome the gravity of the gravity valve 600, the gravity valve 600 opens and exhausts, and the air pressure in the second accommodating chamber 112 drops rapidly. When the air pressure change rate is greater than a preset threshold, the drive circuit 300 can trigger the action of stopping the conduction of the reactant assembly 900, so that the reactant assembly 900 is no longer conducted, and then the reactant assembly 900 no longer reacts and generates gas, so that the moving part 200 no longer moves along the Figure 1-Figure 4If the movement from x' to x in the direction of the axial line 200 is stopped, the insulin push is stopped.

[0064] When the air pressure in the second accommodating chamber 112 drops to a level that is insufficient to overcome the gravity of the gravity valve 600, the gravity valve 600 is closed. At this time, the pressure sensor 500 detects that the air pressure in the second accommodating chamber 112 has not changed significantly. At this time, the air pressure change rate is less than or equal to the preset threshold value, and the driving circuit 300 turns on the reactant assembly 900 again, so that the reactant assembly 900 reacts and generates gas, thereby causing the moving part 200 to move along the axis again. Figure 1-Figure 2 The movement from x' to x in the direction of the axial line continues to push insulin, and the cycle continues, thereby simulating the physiological secretion pattern of insulin, thereby maintaining the user's blood sugar stability throughout the day and achieving the purpose of controlling diabetes.

[0065] See also Figure 3 and Figure 4 In some embodiments of the present application, the reactant assembly 900 of the driving device provided includes a first reactant 910, a conductive member 920, and a second reactant 930 arranged in sequence from the second accommodating chamber 112 to one side of the first accommodating chamber 111; the side wall of the conductive member 920 is connected to the side wall of the second accommodating chamber 112 to separate the second accommodating chamber 112 into a first storage chamber 1121 and a second storage chamber 1122; the first reactant 910 is accommodated in the first storage chamber 1121, and the second reactant 930 is stored in the second storage chamber 1122; the conductive member 920 is connected to the driving circuit 300, and the driving circuit 300 can conduct the conductive member 920; when the conductive member 920 is conducted, the first reactant 910 can pass through the conductive member 920 and contact the second reactant 930, so that the first reactant 910 and the second reactant 930 react and generate gas.

[0066] The second accommodating chamber 112 is divided into a first storage chamber 1121 and a second storage chamber 1122 by the conductive member 920, so that the first reactant 910 and the second reactant 930 are respectively contained in the first storage chamber 1121 and the second storage chamber 1122. When the conductive member 920 is turned on under the action of the driving circuit 300, the first reactant 910 can pass through the conductive member 920 and contact the second reactant 930, so that the first reactant 910 and the second reactant 930 react and generate gas. It can be seen that when the conductive member 920 is turned on, it can be controlled whether the first reactant 910 can pass through the conductive member 920 and move to the second storage chamber 1122 to contact the second reactant 930; when the conductive member 920 is not turned on, the first reactant 910 will not pass through the conductive member 920 and contact the second reactant 930, and the entire reaction process is safe and controllable.

[0067] When the reactant assembly 900 includes a first reactant 910, a conductive member 920, and a second reactant 930, the conductive member 920 in the reactant assembly 900 may be a capillary membrane, and the first reactant 910 and the second reactant 930 are chemicals that can react in pairs and generate gas. For example, hydrogen peroxide solution and catalyst manganese dioxide, sodium bicarbonate powder and acetic acid, sodium carbonate solution and aluminum sulfate, water and sodium nitrite solid and zinc powder, etc. Through the electrowetting effect of the capillary membrane, one of the liquid reactants can pass through the capillary membrane and contact with the other reactant, thereby reacting and generating gas.

[0068] See also Figure 5 The conductive member 920 of the driving device provided in one embodiment of the present application includes a first electrode 921, a hydrophobic layer 922 of a dielectric material, and a second electrode 923 which are sequentially arranged along the extension direction of the second accommodating cavity 112; the first electrode 921 is connected to the positive electrode of the driving circuit 300, and the second electrode 923 is connected to the negative electrode of the driving circuit 300; when the first electrode 921 and the second electrode 923 are simultaneously turned on, the first reactant 910 can sequentially pass through the first electrode 921, the hydrophobic layer 922 of the dielectric material, and the second electrode 923 to contact the second reactant 930.

[0069] When the first electrode 921 and the second electrode 923 are turned on at the same time, the first reactant 910 can undergo electrowetting at the conductive member 920, thereby introducing the first reactant 910 in the first storage chamber 1121 into the second storage chamber 1122, and the first reactant 910 and the second reactant 930 contact and react in the second storage chamber 1122 to produce gas, and the control is very intelligent. It should be noted that in another embodiment, the first electrode 921 can also be connected to the negative electrode of the driving circuit 300, and the second electrode 923 can be connected to the positive electrode of the driving circuit 300. There is no special limitation on this, as long as the two electrodes are connected to the positive and negative electrodes of the circuit respectively.

[0070] In one specific embodiment, the first reactant 910 is a hydrogen peroxide solution, the conductive member 920 is a capillary membrane, and the second reactant 930 is manganese dioxide. When the first electrode 921 and the second electrode 923 of the capillary membrane are energized, the hydrogen peroxide solution can undergo electrowetting at the capillary membrane, so that the hydrogen peroxide solution sequentially passes through the first electrode 921, the dielectric material hydrophobic layer 922, and the second electrode 923, and contacts the catalyst manganese dioxide, and then decomposes under the catalytic action of the manganese dioxide to produce water and oxygen, so that the oxygen pushes the moving member 200 along the Figure 1-Figure 4When the first electrode 921 and the second electrode 923 of the capillary membrane are powered off, the hydrogen peroxide solution no longer undergoes electrowetting, and no new hydrogen peroxide solution contacts the manganese dioxide catalyst, so the reaction of the reactant assembly 900 also stops, and no new oxygen is generated.

[0071] See also Figure 3 and Figure 4 The driving device of the driving device provided in some embodiments of the present application further includes a pressure sensor 500, which is installed in the second storage cavity 1122. The pressure sensor 500 is electrically connected to the driving circuit 300, and the pressure sensor 500 is used to detect the rate of change of the air pressure in the second storage cavity 1122. By arranging the pressure sensor 500 in the second storage cavity 1122, when the reactant assembly 900 reacts to generate gas, the rate of change of the air pressure in the second storage cavity 1122 can be monitored in real time through the pressure sensor 500, so that the user can know the change of the air pressure in real time, avoid the air pressure in the second storage cavity 1122 from changing too fast in a short time, and be safer and more reliable.

[0072] See also Figure 3 and Figure 4 , the driving circuit 300 of the driving device provided in some embodiments of the present application is used to trigger the action of stopping the conduction of the reactant component 900 when the rate of change of the air pressure in the second storage cavity 1122 is greater than the preset threshold. When the rate of change of the air pressure in the second storage cavity 1122 is greater than the preset threshold, the driving circuit 300 triggers the action of stopping the conduction of the reactant component 900, so that the reactant component 900 no longer reacts and produces gas, so as to prevent the further increase of the rate of change of the air pressure, which is safer. It should be noted that there is no restriction on the numerical value of the preset threshold, which can be selectively set according to actual use.

[0073] See also Figure 3 and Figure 4 , the driving device provided in some embodiments of the present application further includes a gravity valve 600, which is installed on the side wall of the second storage chamber 1122; when the air pressure in the second storage chamber 1122 is greater than a preset value, the gravity valve 600 opens; when the air pressure in the second storage chamber 1122 is less than or equal to the preset value, the gravity valve 600 closes. By setting the gravity valve 600, when the air pressure in the second storage chamber 1122 is greater than the preset value, the gravity valve 600 can automatically open and perform exhaust operation, thereby preventing the air pressure in the second storage chamber 1122 from being too high, and making the use of the entire driving device safer. It should be noted that there is no restriction on the numerical value of the preset value, which can be selectively set according to actual usage.

[0074] In one embodiment, when the air pressure in the second storage chamber 1122 gradually increases to overcome the gravity of the gravity valve 600, the gravity valve 600 opens and exhausts, and the air pressure in the second storage chamber 1122 drops rapidly. When the air pressure change rate is greater than a preset threshold, the drive circuit 300 can trigger the action of stopping the conduction of the reactant assembly 900, so that the reactant assembly 900 is no longer conducted, and the reactant assembly 900 no longer reacts and generates gas, so that the moving part 200 no longer moves along the Figure 1-Figure 4 If the movement from x' to x in the direction of the axial line 200 is stopped, the insulin push is stopped.

[0075] When the air pressure in the second storage chamber 1122 drops to a level that is insufficient to overcome the gravity of the gravity valve 600, the gravity valve 600 is closed. At this time, the pressure sensor 500 detects that the air pressure in the second storage chamber 1122 has not changed significantly. At this time, the air pressure change rate is less than or equal to the preset threshold value, and the driving circuit 300 turns on the reactant assembly 900 again, so that the reactant assembly 900 reacts and generates gas, thereby causing the moving part 200 to move along the axis again. Figure 1-Figure 4 The movement from x' to x in the direction of the axial line continues to push insulin, and the cycle continues, thereby simulating the physiological secretion pattern of insulin, thereby maintaining the user's blood sugar stability throughout the day and achieving the purpose of controlling diabetes.

[0076] See also Figure 1-Figure 4 and Figure 6 The driving device provided in some embodiments of the present application further includes a feed port 1123, which is provided on the side wall of the second accommodating chamber 112. By providing the feed port 1123, when the reactant assembly 900 is consumed, it can be added through the feed port 1123.

[0077] See also Figure 1 , Figure 2 and Figure 6 In some embodiments, there is only one feed port 1123 , and when the first reactant 910 needs to be added after being consumed, the feed is directly added through the feed port 1123 .

[0078] See also Figure 3 and Figure 4 In some other embodiments, the second accommodating chamber 112 is isolated into two storage chambers, and is used to place the first reactant 910 and the second reactant 930 respectively. Therefore, the number of the first feeding ports 1123 is two, which are respectively arranged on the cavity walls of the first storage chamber 1121 and the second storage chamber 1122 for adding the first reactant 910 and the second reactant 930.

[0079] See also Figure 1 and Figure 3 In some embodiments, the feeding port 1123 and the gravity valve 600 are separately provided, and each of them has an opening 1111, thereby making the entire device simpler and more convenient when performing feeding operations.

[0080] See also Figure 2 and Figure 4 In some other embodiments, the feed port 1123 and the gravity valve 600 can also be configured to share a common opening 1111, thereby making the punching process of the entire device simpler and more convenient.

[0081] See also Figure 1-Figure 4 and Figure 6 The drive device provided in some embodiments of the present application also includes a Bluetooth module 700, which is connected to the drive circuit 300 for communication, and the Bluetooth module 700 is used to be connected to an external control device. By providing a Bluetooth module 700 connected to the external control device, the user can control the power of the drive device by manipulating the external control device, and the entire drive device is more intelligent. For example, when the external control device is an intelligent device such as a mobile phone or a tablet computer, the control of the drive circuit 300 of the drive device can be achieved by performing touch operations on an APP preset on the mobile phone. When the drive device is installed on an insulin pump, the push injection of insulin can be controlled more intelligently, and the design is more user-friendly.

[0082] In one specific embodiment, a control module is provided in the driving circuit 300, and the control module is in communication with the Bluetooth module 700. When the user inputs an infusion instruction through an external control device, under the control of the control module, the driving circuit 300 receives the corresponding control instruction and starts to input a current of a corresponding magnitude to the heating wire, or controls the conduction time of the conducting member 920, so that the reactant assembly 900 reacts and generates a gas of a preset volume, thereby moving the moving member 200, thereby achieving control of the amount of insulin flowing out of the opening 1111.

[0083] The present application also provides an insulin pump, which includes the driving device described in any of the above embodiments, and also includes a syringe, which is connected to the opening 1111. By connecting the syringe to the opening 1111, when the reactant assembly 900 reacts and generates gas under the conduction of the driving circuit 300, the insulin pre-installed in the first accommodating chamber 111 can be injected from the syringe at the opening 1111, and the technical effect described in any of the above embodiments can be achieved.

[0084] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
