DETAILED DESCRIPTION

[0058] As described in the background, the syringe includes a liquid storage device having an accommodating cavity, and a needle connected to the accommodating cavity to allow the accommodating cavity to suck or discharge fluid through the needle. However, the above-mentioned syringe has a single function, and the syringe can only be used to achieve the process of sucking and discharging fluid, and the syringe cannot obtain the current state of the receptor, and the application range of the syringe is small.

[0059] In order to solve the above technical problems, the embodiments of the present application provide an intelligent syringe and an intelligent injection device, the intelligent syringe includes a liquid storage device, a needle, a first detection unit and a second detection unit, when the syringe is used to suck fluid from the receptor or discharge fluid to the receptor, the end of the needle away from the liquid storage device is inserted into the tissue of the receptor, and then the volume of the accommodating cavity is adjusted, so that the accommodating cavity sucks or discharges fluid through the injection channel; at the same time, the first detection unit arranged in the accommodating cavity and / or the injection channel detects the pressure of the fluid in the accommodating cavity, and the second detection unit arranged on the outer surface of the needle can detect the pressure of the fluid in the tissue of the receptor, so that the first detection unit and the second detection unit can cooperate with each other, and the permeability components of the tissue of the receptor in different directions can be obtained according to the Darcy formula and other fluid formulas, thereby enriching the function of the syringe and expanding the application range of the syringe.

[0060] The exemplary embodiments will be described in detail herein with reference to the drawings. Descriptions of well-known functions and structures are omitted so as not to unnecessarily obscure the application. The examples described herein represent the preferred embodiments of the application, and as such, those skilled in the art will recognize that variations of the preferred embodiments fall within the scope of the application. Accordingly, the application is not limited to that precisely as shown and described.

[0061] The technical solutions of the present application and how the technical solutions solve the above technical problems will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described again in some embodiments. The embodiments of the present application will be described below with reference to the drawings.

[0062] With reference to Figures 1-4 The embodiments of the present application provide an intelligent injector, which comprises a liquid storage device 100, a needle 200, a first detection unit 300 and a second detection unit 400; the liquid storage device 100 is provided with a volume-adjustable containing cavity 130, and the containing cavity 130 is used for containing fluid; the inner surface of the needle 200 is formed with an injection channel 230, and the injection channel 230 is communicated with the containing cavity 130, so that the containing cavity 130 can suck or discharge fluid through the injection channel 230.

[0063] For example, when the intelligent injector is used to inject a subject 700, the fluid in the containing cavity 130 is set as a drug solution, the volume of the containing cavity 130 is compressed, so that the drug solution can flow to the subject 700 through the injection channel 230, to realize the injection process; when the intelligent injector is used to extract fluid from the subject 700, the fluid in the containing cavity 130 is set as the body fluid of the subject 700, the volume of the containing cavity 130 is expanded, so that the body fluid can flow from the subject 700 to the containing cavity 130 through the injection channel 230, to realize the extraction process.

[0064] With reference to Figure 5 In some possible embodiments, the needle 200 is further provided with a containing groove 210, the containing groove 210 is arranged on the outer surface of the needle 200; the first detection unit 300 is arranged in the containing cavity 130 and / or the injection channel 230, so as to obtain the pressure of the fluid in the containing cavity 130 through the first detection unit 300; the second detection unit 400 is arranged in the containing groove 210, and the second detection unit 400 is flush with the outer surface of the needle 200, so as to obtain the pressure of the subject 700 through the second detection unit 400, and by arranging the second detection unit 400 in the containing groove 210, the interference of the second detection unit 400 on the process of inserting the needle 200 into the subject 700 is reduced.

[0065] It is easy to understand that the signal terminals of the first detection unit 300 and the second detection unit 400 can send signals to the same controller, and the signals from the first detection unit 300 and the second detection unit 400 are analyzed by the controller, so as to obtain the horizontal permeability and the vertical permeability of the tissue of the receptor 700 according to the pressure of the fluid in the containing cavity 130 and the pressure of the tissue fluid of the receptor 700.

[0066] In addition, by arranging the first detection unit 300 and the second detection unit 400, the permeability components of the receptor 700 in different directions, the compressibility of the tissue fluid of the receptor 700, and the anisotropy of the tissue fluid can be obtained by the cooperation of the first detection unit 300 and the second detection unit 400, so as to make the function of the intelligent injector more abundant.

[0067] Referring to Figures 1-4 In some possible embodiments, the liquid storage device 100 comprises a liquid storage cylinder 110 and an adjusting member 120; the liquid storage cylinder 110 comprises a main body 111 and a blocking member 112, the main body 111 extends along a first direction, and the cross section of the main body 111 perpendicular to the first direction can be circular.

[0068] For example, the adjusting member 120 is movably arranged in the liquid storage cylinder 110, the adjusting member 120 can move towards or away from the blocking member 112 along the first direction, the edge of the adjusting member 120 abuts against the inner wall of the main body 111, and the adjusting member 120, the blocking member 112 and at least part of the main body 111 jointly form the containing cavity 130, so as to adjust the volume of the containing cavity 130 by the adjusting member 120, thereby realizing the adjusting process of the volume of the fluid in the containing cavity 130.

[0069] In addition, the needle 200 can be arranged on the surface of the blocking member 112 away from the main body 111, and the needle 200 extends along the first direction, so that the fluid flows from the blocking member 112 to the needle 200 during the process that the adjusting member 120 moves towards the blocking member 112 along the first direction, thereby realizing the flow process of the fluid.

[0070] In some possible embodiments, the first detection unit 300 can comprise one pressure detection member, or the first detection unit 300 can further comprise a plurality of pressure detection members, and the embodiments of the present application do not make further limitation as long as the detection effect of the pressure of the fluid in the containing cavity 130 can be ensured.

[0071] For example, the first detection unit 300 includes a plurality of pressure detection members. For example, the first detection unit 300 can include a first detection member 310, a second detection member 320, and a third detection member 330. The first detection member 310 is arranged on the surface of the adjusting member 120 facing the blocking member 112. The second detection member 320 is arranged on the main body 111 and is flush with the inner surface of the main body 111. The third detection member 330 is arranged on the inner surface of the needle 200 and is flush with the inner surface of the needle 200. Thus, the pressure of the fluid in the accommodation cavity 130 is detected by the first detection member 310, the second detection member 320, and the third detection member 330, so that the detection result of the fluid pressure is more accurate.

[0072] It is easy to understand that, among the first detection member 310, the second detection member 320, and the third detection member 330, the first detection member 310 is arranged on the surface of the adjusting member 120, and the volume of the first detection member 310 can be greater than the volume of the second detection member 320 and the volume of the third detection member 330, and the cost of the first detection member 310 is less than the cost of the second detection member 320 and the cost of the third detection member 330.

[0073] The second detection member 320 is arranged on the main body 111 and is flush with the inner surface of the main body 111. The connecting line of the second detection member 320 can be arranged in the inner wall of the main body 111, so as to reduce the interference of the second detection member 320 on the movement process of the adjusting member 120. The third detection member 330 is arranged on the inner surface of the needle 200 and is flush with the inner surface of the needle 200. Part of the connecting line of the third detection member 330 is arranged in the inner wall of the needle 200, and part of the connecting line of the third detection member 330 is arranged in the inner wall of the main body 111.

[0074] For example, the first detection unit 300 can also include one or two of the first detection member 310, the second detection member 320, and the third detection member 330, as long as the accuracy of the detection result of the first detection unit 300 can be ensured. The embodiments of the present application do not make further limitations.

[0075] Referring to Figures 1-5 In some possible embodiments, the second detection unit 400 can include one pressure detection member, or the second detection unit 400 can also include a plurality of pressure detection members. The embodiments of the present application do not make further limitations as long as the detection effect of the fluid pressure of the tissue of the recipient 700 can be ensured.

[0076] Exemplarily, the second detection unit 400 comprises a fourth detection member 410 and a fifth detection member 420, the fourth detection member 410 and the fifth detection member 420 are arranged along the first direction, and the fourth detection member 410 is arranged at the second end of the needle 200, so as to detect the fluid pressure of the tissue of the subject 700 through the fourth detection member 410 and the fifth detection member 420, thereby ensuring the detection accuracy of the fluid pressure of the tissue of the subject 700.

[0077] By adopting the technical scheme, when the intelligent injector is used to inject the liquid medicine into the tissue of the subject 700, the first detection member 310, the second detection member 320 and the third detection member 330 of the first detection unit 300 can detect the pressure of the fluid in the accommodating cavity 130 and transmit the signal to the controller, and the fourth detection member 410 and the fifth detection member 420 of the second detection unit 400 can detect the fluid pressure of the tissue of the subject 700 and transmit the signal to the controller, the controller analyzes the signals from the first detection unit 300 and the second detection unit 400, so as to obtain the horizontal permeability and the vertical permeability of the tissue of the subject 700 according to the fluid pressure in the accommodating cavity 130 and the pressure of the tissue of the subject 700, so as to make the function of the intelligent injector more abundant.

[0078] With reference to Figure 2 And Figure 3 In some possible implementation manners, the adjusting member 120 is provided with a flexible film 121, the flexible film 121 is arranged on the surface of the adjusting member 120 facing the plugging member 112, and a sensing cavity 122 is formed between the flexible film 121 and the adjusting member 120, the sensing cavity 122 is used for accommodating a sensing fluid; the sensing cavity 122 and the accommodating cavity 130 are arranged along the first direction, and a sixth detection member 123 is further arranged in the sensing cavity 122, the sixth detection member 123 is used for detecting the pressure of the sensing fluid.

[0079] Exemplarily, in the sensing cavity 122, the sensing fluid can be air or other gas, or the sensing fluid can also be liquid, and the present application does not make further limitation on this. In addition, the compression ratio of the sensing fluid can be greater than that of the fluid in the accommodating cavity 130, so as to amplify the change amount of the fluid pressure in the accommodating cavity 130, thereby making the detection process of the change amount of the fluid pressure in the accommodating cavity 130 more accurate.

[0080] It is easy to understand that when the volume of the fluid injected into the tissue of the subject 700 by the intelligent injector is small, or when the flow rate of the fluid injected into the tissue of the subject 700 by the intelligent injector is low, the change amount of the pressure of the fluid in the accommodating cavity 130 is small, so that the change of the pressure obtained by the first detection unit 300 of the intelligent injector is small, thereby affecting the accuracy of the intelligent injector in obtaining the pressure in the accommodating cavity 130.

[0081] With reference toFigure 3 In some possible implementation manners, the induction cavity 122 is provided with a one-way control member 125, an inlet of the one-way control member 125 is in communication with an outer side of the induction cavity 122, and an outlet of the one-way control member 125 is in communication with an inner side of the induction cavity 122, so that the induction fluid can flow from the outer side of the induction cavity 122 to the inner side of the induction cavity 122 through the one-way control member 125; and the induction cavity 122 is further provided with a filter member 126, the filter member 126 is arranged at the inlet of the one-way control member 125, so that the induction fluid is filled into the induction cavity 122 through the filter member 126 and the one-way control member 125.

[0082] For example, the one-way control member 125 and the filter member 126 are arranged on the adjusting member 120; the adjusting member 120 is provided with a communication pipe 124, a first end of the communication pipe 124 contains the one-way control member 125 and the filter member 126, and a second end of the communication pipe 124 is used to communicate with a filling device, so that the filling device fills the induction fluid into the induction cavity 122 through the communication pipe 124.

[0083] It is easy to understand that the one-way control member 125 and the filter member 126 are detachably arranged on the adjusting member 120, so that the one-way control member 125 and the filter member 126 are more easily disassembled, and the filter member 126 is more easily cleaned.

[0084] By using the above technical solution, when the induction fluid needs to be filled into the induction cavity 122, the induction fluid can be filled from the outer side of the induction cavity 122 to the inner side of the induction cavity 122 through the one-way control member 125, and the filter member 126 arranged at the inlet of the one-way control member 125 can filter the induction fluid to some extent, so as to reduce the possibility that the induction fluid in the induction cavity 122 is polluted.

[0085] Reference Figure 4 In some possible implementation manners, the adjusting member 120 is provided with a liquid injection channel 510, a first end of the liquid injection channel 510 is in communication with the containing cavity 130, and a second end of the liquid injection channel 510 is used to communicate with a liquid injection device 500, so that the liquid injection device 500 discharges the fluid into the containing cavity 130 through the liquid injection channel 510; and / or the adjusting member 120 is further provided with a detection channel 140 and a seventh detection member 141, a first end of the detection channel 140 is in communication with the containing cavity 130, and the seventh detection member 141 is installed on the detection channel 140, so that the pressure of the fluid in the containing cavity 130 is obtained through the seventh detection member 141.

[0086] For example, the liquid injection device 500 can discharge the fluid into the containing cavity 130 at a set flow rate, for example, the set flow rate of the fluid can be a constant flow rate, or the set flow rate can be gradually increased or in a sinusoidal curve, and the present application does not make further limitation.

[0087] By adopting the technical scheme, when the liquid injection device 500 discharges fluid into the containing cavity 130 through the liquid injection channel 510, part of the fluid flows from the containing cavity 130 to the detection channel 140, and the seventh detection member 141 arranged in the detection channel 140 can detect the pressure of the fluid in the containing cavity 130, so as to cooperate with the second detection unit 400 to more accurately obtain the permeability component of the tissue of the subject 700.

[0088] In addition, when the volume of the containing cavity 130 remains constant, that is, the fluid in the containing cavity 130 is injected into the tissue of the subject 700 through the injection channel 230, and the liquid injection device 500 discharges fluid into the containing cavity 130 through the liquid injection channel 510, the seventh detection member 141 arranged in the detection channel 140 can cooperate with the second detection unit 400 to more accurately obtain the permeability component of the tissue of the subject 700.

[0089] With reference to Figure 5 In some possible implementation manners, the end of the needle 200 away from the liquid storage device 100 is provided with a piercing portion 240, and the piercing portion 240 has an inclined surface which is arranged to be inclined with respect to the extension direction of the needle 200, so as to make the process of the needle 200 piercing into the tissue of the subject 700 easier; and the piercing portion 240 is further provided with a sampling member 220, the sampling member 220 is arranged on the inner surface of the needle 200, and at least part of the sampling member 220 is arranged to protrude from the inner surface of the needle 200 towards the inclined surface, so as to obtain part of the body fluid from the tissue of the subject 700 and / or part of the cells from the tissue of the subject 700 through the sampling member 220.

[0090] For example, the sampling member 220 includes a fitting portion 221 and a bent portion 222 which are connected, the fitting portion 221 is arranged on the inner surface of the needle 200 and is arranged flush with the inner surface of the needle 200, the first end of the bent portion 222 is connected to the fitting portion 221, the second end of the bent portion 222 extends towards the liquid storage device 100, and the bent portion 222 is arranged to be inclined with respect to the extension direction of the needle 200, so as to obtain part of the body fluid from the tissue of the subject 700 and / or part of the cells from the tissue of the subject 700 through the bent portion 222.

[0091] For example, the needle 200 is provided with a scale which is arranged uniformly along the first direction, and the scale is used to indicate the length of the needle 200 located in the tissue of the subject 700, so as to make the process of obtaining data of the first detection unit 300 and the second detection unit 400 more accurate.

[0092] With reference to Figure 6 and Figure 7In some possible embodiments, the number of the needle 200 is set to be multiple, the multiple needles 200 are all in communication with the accommodating cavity 130, and each needle 200 is provided with the first detection unit 300 and the second detection unit 400.
