[0006] The first shell comprises a cover body and a box body which are arranged opposite to each other, and the filter membrane is sandwiched between the cover body and the box body;

[0007] The cover body comprises a top cover and a side wall arranged around the periphery of the unfiltered cavity, and an opening communicating with the unfiltered cavity is formed on the side wall near the liquid inlet.

[0008] In the present technical solution, by setting a specific structure of the filter, the insoluble particles in the medicine liquid can be effectively filtered after the medicine liquid flows through the filter membrane; at the same time, the liquid outlet is connected to the top of the side wall of the filtered cavity away from the filter membrane, so that the medicine liquid can leave the filtered cavity only after it fills the filtered cavity, and the air on the filter membrane can be exhausted, avoiding the generation of bubbles on the filter membrane to affect the lower liquid, and ensuring the normal flow of the medicine liquid. Further, by setting the first shell to include a relatively arranged cover body and a box body, the filter membrane is clamped between the cover body and the box body, and a preferred structure of the first shell is provided, which is convenient for the installation of the filter membrane. Further, by setting the cover body to include a top cover and a side wall arranged around the periphery of the unfiltered cavity, an opening connected to the unfiltered cavity is opened on the side wall near the liquid inlet, so that the structure of the cover body is compact, the unfiltered cavity is formed by the side wall, and the medicine liquid enters the unfiltered cavity through the opening opened on the side wall.

[0009] Preferably, a medicine outlet channel arranged in a vertical direction is provided between the liquid outlet and the filtered cavity, the top of the medicine outlet channel is connected to the top of a side wall of the filtered cavity away from the filter membrane, and the liquid outlet is arranged at the bottom end of the medicine outlet channel.

[0012] In the present technical solution, a vertical drug inlet channel connected to the top of the unfiltered chamber is provided to allow the drug solution to enter through the top of the unfiltered chamber. Thus, after filling the unfiltered chamber, the drug solution can pass through the filter membrane and enter the filtered chamber, thereby discharging the air in the unfiltered chamber and preventing the air from adhering to the filter membrane.

[0013] Preferably, a transverse drug feed channel arranged along the horizontal direction is also provided between the vertical drug feed channel and the unfiltered chamber, and one end of the transverse drug feed channel along the horizontal direction is connected to the bottom end of the vertical drug feed channel, and the other opposite end is connected to the top end of the unfiltered chamber.

[0014] In the technical solution, by providing a transverse drug inlet channel, the drug solution first passes through the transverse drug inlet channel and then enters the unfiltered cavity, thereby buffering the impact force of the drug solution on the filter membrane.

[0015] Preferably, the filtering device further comprises a joint, and the joint is arranged at the liquid outlet;

[0016] The connector is a Luer connector.

[0021] In this technical solution, when the drug solution is concentrated on one side of the filter membrane, a certain force will be exerted on the filter membrane. By providing a support member, the filter membrane can resist the force, prevent the filter membrane from deformation, and extend the service life of the filter membrane.

[0022] Preferably, the inner wall surface of the top cover corresponding to the position of the unfiltered cavity is an arc-shaped wall surface.

[0023] In the technical solution, the inner wall surface of the top cover corresponding to the position of the unfiltered cavity is set to be an arc-shaped wall surface, so that after entering the unfiltered cavity from the opening, it can flow along the arc-shaped wall surface to the bottom of the unfiltered cavity.

[0024] Preferably, the infusion switch comprises a second shell and an actuator, a flow channel is provided in the second shell, the flow channel is communicated with the liquid inlet of the first shell of the filter, and the actuator is used to close or open the flow channel.

[0025] In the present technical solution, by setting the specific structure of the infusion switch, the flow channel can be completely closed, so that even if the part (filter) located below the infusion switch is an open structure, it will not affect the closed structure of the medicine located above the infusion switch. In other words, the infusion switch isolates the upper and lower parts of the infusion switch, so that the part located below the infusion switch can be a sealed structure or an open structure, which has the possibility of more functional configurations.

[0026] The positive and progressive effects of the present invention are:

[0027] The present invention sets a specific structure of the filter so that after the medicine liquid flows through the filter membrane, the insoluble particles in the medicine liquid are effectively filtered out; at the same time, the liquid outlet is connected to the top of the side wall of the filtered cavity away from the filter membrane, so that the medicine liquid can leave the filtered cavity only after it fills the filtered cavity, and the air on the filter membrane can be discharged, thereby avoiding the generation of bubbles on the filter membrane to affect the lower liquid, and ensuring the normal flow of the medicine liquid.

[0069] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0070] like Figures 1 to 9 As shown, this embodiment provides an infusion package with the function of removing insoluble particles. The infusion package includes a bag body 2 and a filter device 1 that are connected. The filter device 1 includes an infusion switch 10 and a filter 20 that are connected in sequence along the flow direction of the liquid medicine.

[0071] The filter 20 includes a first shell 21, in which a accommodating chamber 22 is provided. A filter membrane 23 is provided in the accommodating chamber 22 along the vertical direction H. The filter membrane 23 divides the accommodating chamber 22 into an unfiltered chamber 221 and a filtered chamber 222. A liquid inlet 241 is provided at the top end of the first shell 21, and a liquid outlet 242 is provided at the bottom end. The liquid inlet 241 is communicated with the top end of the unfiltered chamber 221, and the liquid outlet 242 is communicated with the top end of a side wall 214 of the filtered chamber 222 away from the filter membrane 23.

[0072] In this way, by setting the specific structure of the filter 20, the insoluble particles in the medicine liquid can be effectively filtered out after the medicine liquid flows through the filter membrane 23; at the same time, the liquid outlet 242 is connected to the top of the side wall 214 of the filtered cavity 222 away from the filter membrane 23, so that the medicine liquid can leave the filtered cavity 222 only after it fills the filtered cavity 222, and the air on the filter membrane 23 can be discharged, thereby avoiding the generation of bubbles on the filter membrane 23 to affect the liquid below, thereby ensuring the normal flow of the medicine liquid.

[0073] like Figure 6 As shown in the figure, the direction of the liquid medicine flow is indicated by the arrow direction. It can be seen that after the liquid medicine enters the unfiltered cavity 221, it enters the filtered cavity 222 through the filter membrane 23; because the liquid outlet 242 is connected to the top of the side wall 214 of the filtered cavity 222 away from the filter membrane 23, that is, the outlet of the filtered cavity 222 is located at the top of the side wall 214 of the filtered cavity 222 away from the filter membrane 23, the liquid medicine must fill all the space below the outlet of the filtered cavity 222 before it can flow out from the outlet, so that the air on the filter membrane 23 can be exhausted, avoiding the generation of bubbles on the filter membrane 23 to affect the liquid, and ensuring the normal flow of the liquid medicine.

[0074] Preferably, a medicine outlet channel 253 is provided between the liquid outlet 242 and the filtered cavity 222 along the vertical direction H to lead the filtered liquid medicine out of the filter 20. The top of the medicine outlet channel 253 is connected to the top of a side wall 214 of the filtered cavity 222 away from the filter membrane 23, and the liquid outlet 242 is provided at the bottom of the medicine outlet channel 253.

[0075] In this embodiment, along the thickness direction W of the first shell 21, part of the outer wall surface of the drug outlet channel 253 protrudes from the first shell 21 to reduce the overall thickness of the first shell 21 and achieve the beneficial technical effect of saving manufacturing costs.

[0076] A vertical medicine inlet channel 251 is provided between the liquid inlet 241 and the unfiltered cavity 221 along the vertical direction H, and the vertical medicine inlet channel 251 is communicated with the top of the unfiltered cavity 221. In this way, by providing the vertical medicine inlet channel 251 communicated with the top of the unfiltered cavity 221, the medicine liquid enters through the top of the unfiltered cavity 221, so that after filling the unfiltered cavity 221, the medicine liquid can enter the filtered cavity 222 through the filter membrane 23, that is, the air in the unfiltered cavity 221 can be discharged, thereby preventing the air from adhering to the filter membrane 23.

[0077] Preferably, a horizontal drug inlet channel 252 is provided between the vertical drug inlet channel 251 and the unfiltered cavity 221, and one end of the horizontal drug inlet channel 252 is connected to the bottom end of the vertical drug inlet channel 251, and the other end is connected to the top end of the unfiltered cavity 221. In this way, by providing the horizontal drug inlet channel 252, the drug solution first passes through the horizontal drug inlet channel 252 and then enters the unfiltered cavity 221, which buffers the impact of the drug solution on the filter membrane 23. Among them, a connecting port 2521 is provided at one end of the horizontal drug inlet channel 252 close to the unfiltered cavity 221, and the horizontal drug inlet channel 252 is connected to the unfiltered cavity 221 through the connecting port 2521. The lower end of the connecting port 2521 is a downwardly inclined slope, so that by gradually increasing the cross-sectional area of ​​the connecting port 2521, the drug solution can flow into the unfiltered cavity 221 more quickly.

[0078] In this embodiment, the filter device 1 further includes a connector 30, which is disposed at the liquid outlet 242 of the first housing 21. By providing the connector 30, the filter device 1 can be directly used in conjunction with other medical components.

[0079] Preferably, the connector 30 is a Luer connector. As an international standard, the Luer connector 30 can be a male Luer connector or a female Luer connector.

[0080] In this embodiment, the outer edge of the first shell 21 is provided with a reinforcing rib 26 to strengthen the overall strength of the first shell 21. The reinforcing rib 26 extends along the thickness direction W of the first shell 21 to better achieve the technical effect of strengthening the overall strength of the first shell 21.

[0081] The first housing 21 includes a cover 211 and a box 212 that are arranged opposite to each other, and the filter membrane 23 is sandwiched between the cover 211 and the box 212. The cover 211 and the box 212 are engaged to facilitate the installation of the filter membrane 23.

[0082] In this embodiment, the filter 20 further includes a support member 27, which is disposed in the filtered cavity 222, connected to the box body 212, and the filter membrane 23 abuts against one end of the support member 27 away from the box body 212. In this way, when the liquid medicine is concentrated on one side of the filter membrane 23, a certain force will be generated on the filter membrane 23. The support member 27 is provided to resist the force on the filter membrane 23, thereby preventing the filter membrane 23 from being deformed and extending the service life of the filter membrane 23.

[0083] Preferably, the cover body 211 includes a top cover 213 and a side wall 214 arranged around the periphery of the unfiltered cavity 221, and an opening 215 communicating with the unfiltered cavity 221 is provided on the side wall 214 near the liquid inlet 241. Through the above arrangement, the structure of the cover body 211 is compact, the unfiltered cavity 221 is formed by the side wall 214, and the drug liquid enters the unfiltered cavity 221 through the opening 215 provided on the side wall 214. The inner wall surface of the top cover 213 corresponding to the position of the unfiltered cavity 221 is an arc-shaped wall surface, so that after entering the unfiltered cavity 221 through the opening 215, it can flow along the arc-shaped wall surface to the bottom of the unfiltered cavity 221, as shown in FIG. Figure 6 shown.

[0084] In this embodiment, the infusion switch 10 includes a second housing 11 and an actuator 12. A flow channel 13 is provided in the second housing 11. The flow channel 13 is connected to the liquid inlet 241 of the first housing 21 of the filter 20. The actuator 12 is used to close or open the flow channel 13. By setting the specific structure of the infusion switch 10, the flow channel 13 can be completely closed, so that even if the part (filter 20) located below the infusion switch 10 is an open structure, it will not affect the sealed structure of the liquid medicine located above the infusion switch 10. In other words, the infusion switch 10 isolates the upper and lower parts of the infusion switch 10, so that the part located below the infusion switch 10 can be a sealed structure or an open structure, which has more functional configuration possibilities.

[0085] It should be noted that the portion below the infusion switch 10 is a sealed structure, such as sealing the filter 20 through a rubber plug or other components; the portion below the infusion switch 10 is an open structure, that is, the portion below the infusion switch 10 is not closed, that is, the liquid outlet 242 of the filter 20 is open, and, as in the present embodiment, a connector 30 can be provided at the liquid outlet 242 to enable more convenient use with other medical components.

[0086] The actuator 12 includes a head 121 and a rod 122 connected to each other. One end of the head 121 of the actuator 12 is located outside the second shell 11, and the other end is clamped in the second shell 11; the rod 122 of the actuator 12 is inserted into the flow channel 13 to close or open the flow channel 13. The head 121 is located at one end outside the second shell 11 and extends radially outward to provide a better gripping position. The head 121 can be rotated to drive the rod 122 to rotate, so that the rod 122 moves relative to the second shell 11 to close or open the flow channel 13.

[0087] In other embodiments, the head 121 of the actuator 12 is rotatably connected to the second shell 11 (such as a threaded connection), and the rotating head 121 can also drive the rod 122 to rotate, so that the rod 122 moves relative to the second shell 11 to close or open the flow channel 13.

[0088] Preferably, a sealing sleeve 14 is sleeved on the outer surface of the rod portion 122 of the actuator 12 to improve the sealing performance when the rod portion 122 closes the flow channel 13 .

[0089] In this embodiment, the specific structure of the filter 20 is set so that the insoluble particles in the medicine liquid can be effectively filtered out after the medicine liquid flows through the filter membrane 23; at the same time, the liquid outlet 242 is connected to the top of the side wall 214 of the filtered cavity 222 away from the filter membrane 23, so that the medicine liquid can leave the filtered cavity 222 only after it fills the filtered cavity 222, and the air on the filter membrane 23 can be discharged, thereby avoiding the generation of bubbles on the filter membrane 23 that affect the lower liquid, and ensuring the normal flow of the medicine liquid.
