[0001] The present application relates to the technical field of medical infusion, in particular to an infusion device and an infusion apparatus. BACKGROUND
[0002] Infusion refers to a treatment method of directly inputting liquid medicine, nutrient substance, electrolyte solution or other therapeutic liquid into the blood circulation of a patient through a vein, which is widely applied to various clinical situations and aims to supplement body fluid, provide nutrition, treat diseases or maintain vital signs.
[0003] In the related art, when the infusion bottle needs to be replaced during the infusion process, the operator usually needs to pull out the infusion device from the infusion bottle and then insert it into another infusion bottle. However, in order to maintain the sealing and tightness between the infusion device and the infusion bottle, the pulling-out process is relatively laborious and inconvenient to operate. SUMMARY
[0004] The purpose of the present application is to provide an infusion device and an infusion apparatus to solve the problem of laborious operation when the infusion device is inserted into or pulled out of the infusion bottle in the related art.
[0005] In order to achieve the above-mentioned purpose, the present application provides an infusion device, which comprises an infusion connector and a lever assembly. The infusion connector is used to be inserted into an infusion bottle to guide the liquid in the infusion bottle out. The lever assembly is hingedly arranged at one end of the infusion connector away from the infusion bottle. The lever assembly is divided into an abutting portion and a lever portion by a hinge point. The abutting portion can abut on the infusion bottle. The length of the abutting portion is L1, and the length of the lever portion is L2, which satisfies L1≤L2.
[0006] Further, one end of the infusion connector away from the infusion bottle is connected with an infusion tube. A connecting assembly is arranged between the infusion connector and the infusion tube to make the infusion connector and the infusion tube in liquid communication.
[0007] Further, the connecting assembly comprises a communication portion and a hinge portion. The infusion connector and the infusion tube are connected to the communication portion to keep liquid communication. The hinge portion is arranged at one side of the communication portion, and the lever assembly is hingedly arranged at the hinge portion.
[0008] Further, the communication portion is arranged at the center of the connecting assembly, and the hinge portion is arranged at one side of the communication portion and adjacent to the communication portion.
[0009] Further, the lever assembly comprises a clearance slot, and the connecting assembly is arranged in the clearance slot. The hinge point of the lever assembly and the connecting assembly is also arranged in the clearance slot.
[0010] Further, the let-go groove comprises a groove bottom, and a gap is arranged between an end of the connecting assembly towards the groove bottom and the groove bottom.
[0011] Further, a holding part is arranged on the connecting assembly away from the infusion bottle, and the holding part is arranged between the communicating part and the infusion tube, and the holding part is made of rigid material.
[0012] Further, the length of the holding part is L3, and L3≥L2 is satisfied.
[0013] Further, an opening is arranged on the abutting part close to an end of the abutting part towards the infusion bottle, and the opening is arranged to allow the abutting part to abut on the infusion bottle without obstacles.
[0014] The application also provides an infusion device comprising a support and the infusion apparatus in any one of the above embodiments, and the infusion bottle is hung on the support, and the infusion connector is inserted into the infusion bottle.
[0015] The beneficial effects of the application are as follows:
[0016] The infusion apparatus provided by the application is used for inserting the infusion connector into the infusion bottle for infusion, and when the infusion connector needs to be pulled out of the infusion bottle, the operator presses the pressing lever part to make the pressing lever assembly rotate, and the abutting part abuts on the infusion bottle. Since the length of the pressing lever part is greater than the length of the abutting part, after the pressing force of the operator is applied to one end of the pressing lever part, the force arm of the abutting part is short, that is, the abutting part will abut on the infusion bottle with a force greater than the pressing force, and the infusion connector is pushed away from the infusion bottle, so as to be pulled out of the infusion bottle.
[0017] The infusion apparatus provided by the application can assist the operator to exert force when the infusion connector is pulled out, and the abutting part also abuts on the infusion bottle when the operator exerts force to pull out the infusion connector, so as to push the infusion connector outward, and the resultant force can pull out the infusion connector, which is more labor-saving and easy to operate. In addition, the pressing lever assembly is arranged at the end of the infusion connector away from the infusion bottle, which is convenient for the operator to hold the infusion connector and the pressing lever assembly when the infusion connector is pulled out, so that the operator can exert force more easily, and the infusion apparatus is easy to use.
[0018] Other features and advantages of the application will be described in detail in the following specific embodiments. BRIEF DESCRIPTION OF DRAWINGS

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present application more clear, the following will combine the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, not all. The components of the embodiments of the present application described and shown in the drawings can be arranged and designed in various different configurations.
[0025] In the description of the present application, it should be noted that the positions or location relationships indicated by the terms "inner", "outer" and the like are based on the positions or location relationships shown in the drawings, or the positions or location relationships of the products of the present application when they are usually placed, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the indicated devices or elements must have a particular position, be constructed and operated in a particular position, and therefore cannot be understood as limiting the present application. In addition, the terms "first", "second" and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.
[0026] In the description of the present application, it should be noted that, unless otherwise explicitly specified and limited, the terms "set", "connected" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium, or it can be connected inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0027] The present application provides an infusion set to solve the problem in the related art that it is laborious and inconvenient for an operator to pull out an infusion connector from an infusion bottle.
[0028] See also Figure 1 、 Figure 2 An infusion pump includes an infusion connector 100 and a lever assembly 200. The infusion connector 100 is used to be inserted into an infusion bottle 110 to drain the liquid in the infusion bottle 110. The lever assembly 200 is hingedly arranged at one end of the infusion connector 100 away from the infusion bottle 110; the lever assembly 200 is divided into an abutting portion 210 and a lever portion 220 at a hinge point, and the abutting portion 210 can abut on the infusion bottle 110. The length of the abutting portion 210 is L1, and the length of the lever portion 220 is L2, satisfying: L1≤L2.
[0029] Specifically, when using the infusion set of this embodiment, the infusion connector 100 can be directly plugged into the infusion bottle 110 for normal use. When the liquid infusion in the infusion bottle 110 is completed and the infusion bottle 110 needs to be replaced, the operator can pull out the infusion connector 100 and plug it into another infusion bottle 110.
[0030] When removing the infusion connector 100, the operator holds the end of the infusion connector 100 away from the infusion bottle 110, applying downward force to the infusion connector 100. At the same time, the operator presses the lever portion 220 of the lever assembly 200, applying force to the lever portion 220 in the direction closer to the end of the infusion connector 100, causing the lever portion 220 to move closer to the infusion connector 100. The lever portion 220 then drives the abutting portion 210 to move. The end of the abutting portion 210 closer to the infusion bottle 110 abuts against the infusion bottle 110, and during the process of rotating in the direction closer to the infusion connector 100, the infusion connector 100 is pushed away from the infusion bottle 110, thereby assisting the operator in removing the infusion connector 100 from the infusion bottle 110.
[0031] Because the lever portion 220 of the lever assembly 200 is longer than the abutting portion 210, and according to the principle of leverage, the product of the force and torque on both sides of the hinge is the same, a relatively small force applied by the operator to the lever portion 220 can generate a relatively large thrust at the abutting portion 210. The lever portion 220 is longer than the abutting portion 210, meaning that when the operator applies force to the end of the lever portion 220 away from the hinge, the end of the abutting portion 210 away from the hinge will abut against the infusion bottle 110 with greater force. This allows the operator to remove the infusion connector 100 from the infusion bottle 110 with relatively little effort.
[0032] When the infusion connector 100 is pulled out, the operator holds one end of the infusion connector 100 and presses the lever assembly 200 downward, and the abutting portion 210 pushes the infusion assembly away from the infusion bottle 110, and the resultant force pulls the infusion connector 100 out, which saves the operator's effort, makes the infusion connector 100 of the embodiment easier to pull out, and makes the replacement process of the infusion bottle 110 easier to operate.
[0033] In one embodiment, as shown in Figure 1 , Figure 2 the end of the infusion connector 100 away from the infusion bottle 110 is connected with the infusion tube 120, and the connection assembly 300 is arranged between the infusion connector 100 and the infusion tube 120 to enable the infusion connector 100 and the infusion tube 120 to communicate liquid. The arrangement of the connection assembly 300 between the infusion connector 100 and the infusion tube 120 can effectively prolong the length of the infusion connector 100 that can be held while ensuring that the infusion connector 100 and the infusion tube 120 communicate liquid, thereby further facilitating the operator to exert force when holding the infusion connector 100, making the embodiment easy to operate.
[0034] The infusion connector 100 and the infusion tube 120 communicate liquid through the connection assembly 300, which can effectively prevent liquid leakage and ensure the safety and effectiveness of the infusion process. Specifically, the connection assembly 300 can be provided with sealing elements such as sealing rings or gaskets at the connection according to actual conditions, which can ensure the sealing between the infusion connector 100 and the infusion tube 120 and prevent air from entering or liquid from leaking.
[0035] In one embodiment, as shown in Figure 1 , Figure 2 the connection assembly 300 includes a communication portion 310 and a hinged portion 320, and the infusion connector 100 and the infusion tube 120 are connected to the communication portion 310 to maintain liquid communication. The hinged portion 320 is arranged on one side of the communication portion 310, and the lever assembly 200 is hingedly arranged on the hinged portion 320. The arrangement of the communication portion 310 and the hinged portion 320 on the connection assembly 300 can effectively reduce the installation difficulty of the embodiment by distinguishing the installation positions of the infusion connector 100 and the lever assembly 200.
[0036] In the embodiment, the connection assembly 300 includes a connection plate, and the communication portion 310 is arranged on the connection plate. The connection plate is arranged as a rectangular plate, and the communication portion 310 is arranged as a through hole in the center of the rectangular plate. In this way, the infusion connector 100 is connected to one side of the rectangular plate and communicates with the through hole, and the infusion tube 120 is connected to the other side of the rectangular plate away from the infusion connector 100 and communicates with the through hole, so that the infusion connector 100 and the infusion tube 120 can maintain liquid communication.
[0037] The lever assembly 200 is mounted on the connecting assembly 300, allowing this embodiment to accommodate infusion bottles 110 of varying shapes and sizes, thereby expanding the applicability of the infusion set. In other words, during use, the embodiment can select an appropriate infusion connector 100 based on the actual size of the infusion bottle 110 and attach the infusion connector 100 to the connecting assembly 300. This allows the embodiment to adapt to diverse clinical environments and usage requirements, expanding its applicability and improving its practicality.
[0038] Furthermore, if the lever assembly 200 is installed at one end of the infusion connector 100, the infusion connector 100 would need to be drilled and assembled during installation, which could cause the lever assembly 200 to come into contact with the infusion liquid and contaminate the liquid. Placing the lever assembly 200 on the connecting assembly 300 prevents the lever assembly 200 from coming into contact with the infusion process, preventing it from damaging the infusion connector 100 or contaminating the liquid, and thus preventing the infusion system from coming into contact with the outside world, reducing the risk of infection and improving the safety of this embodiment.
[0039] In one embodiment, for example, Figure 1 、 Figure 2 As shown, the connecting portion 310 is disposed at the center of the connecting assembly 300, and the hinge portion 320 is disposed on one side of the connecting portion 310 and adjacent to the connecting portion 310. The connection portion 310 disposed at the center of the connecting assembly 300 can make the overall structure of the connecting assembly 300 more compact and reasonable, and improve the reliability of the connection between the infusion connector 100 and the infusion tube 120, ensuring smooth liquid flow and preventing bubbles from forming during the flow of the liquid, which could affect normal infusion.
[0040] The hinge portion 320 is provided on one side of the connecting portion 310, making the position of the hinge portion 320 more reasonable. When in use, the operator can easily operate the lever assembly 200 through the hinge portion 320 without the need for additional complicated movements. In actual use, the abutment portion 210 is located on one side of the infusion connector 100, and the lever portion 220 is located on the other side of the infusion connector 100. When the operator pulls out the infusion connector 100, he or she can directly hold the end of the infusion connector 100 away from the infusion bottle 110 and the lever portion 220 at the same time. The process of holding tightly is the process of moving the lever portion 220 closer to the infusion connector 100, that is, the process of the abutment portion 210 pushing the infusion connector 100 out, thereby making this embodiment easier to use.
[0041] The adjacent arrangement of the connecting part 310 and the hinged part 320 can make the abutting part 210 stably abut on the infusion bottle 110 under the gravity after the infusion connector 100 is inserted into the infusion bottle 110, because the length of the lever part 220 of the lever assembly 200 is relatively long and the overall weight is relatively large. When the operator or the infusion operator touches the infusion tube 120 due to misoperation or other reasons, the abutting part 210 will not shake with the shaking of the infusion tube 120, so that the structure of the whole connecting assembly 300 and the lever assembly 200 is more stable, the connection loosening caused by external vibration or collision is avoided, and the continuity and safety of the infusion process are ensured.
[0042] In one embodiment, as shown in Figure 1 , Figure 2 The lever assembly 200 includes a clearance slot 230, and the connecting assembly 300 is arranged in the clearance slot 230. The hinged part of the lever assembly 200 and the connecting assembly 300 is also arranged in the clearance slot 230. In this way, when the lever assembly 200 rotates relative to the connecting assembly 300, the connecting assembly 300 will not interfere with the lever assembly 200, so that the lever assembly 200 can rotate arbitrarily within a suitable range.
[0043] In addition, the clearance slot 230 can also protect the hinged part of the lever assembly 200 and the connecting assembly 300, prevent the parts of the hinged part from being exposed to the external environment, avoid the parts of the hinged part from being knocked with the external environment due to other reasons, and improve the safety of the embodiment.
[0044] In one embodiment, as shown in Figure 1 , Figure 2 The clearance slot 230 includes a slot bottom 231, and a gap is arranged between the end of the connecting assembly 300 facing the slot bottom 231 and the slot bottom 231. A gap is arranged between the connecting assembly 300 and the slot bottom 231, that is, the length between the hinged part 320 and the slot bottom 231 is greater than the length of the connecting assembly 300 in the clearance slot 230, so that the lever part 220 will not be interfered when rotating.
[0045] Specifically, in the process of inserting the infusion connector 100 into the infusion bottle 110, the distance between the connecting assembly 300 and the infusion bottle 110 is shortened. Since the abutting portion 210 is located between the connecting assembly 300 and the infusion bottle 110, in the process of inserting the infusion connector 100, the abutting portion 210 is limited by the infusion bottle 110 and rotates in a direction tending to be horizontal, and the lever portion 220 rotates in a direction tending to be horizontal. A gap is provided between one end of the connecting assembly 300 towards the groove bottom 231 and the groove bottom 231, which can ensure that the connecting assembly 300 does not hinder the normal rotation of the lever portion 220, and thus does not hinder the abutting portion 210 to give way, so that the infusion connector 100 can be normally inserted into the infusion bottle 110.
[0046] Correspondingly, when it is needed to pull out the infusion connector 100, the lever portion 220 is rotated in a direction tending to be vertical, and the abutting portion 210 is rotated accordingly and abuts against the infusion bottle 110, and the infusion connector 100 is pushed away from the infusion bottle 110, so that the pulling-out process is simple and labor-saving.
[0047] In an embodiment, as shown in Figure 1 , Figure 2 , a holding portion 330 is provided on the connecting assembly 300 away from the infusion bottle 110. The holding portion 330 is provided between the communicating portion 310 and the infusion tube 120, and is made of a rigid material. By providing the holding portion 330 on the connecting assembly 300, it is further convenient for the operator to grasp the holding portion 330 when it is needed to insert or pull out the infusion connector 100, so that the operator can easily exert force, and the embodiment is easy to use. The holding portion 330 is rigid, which can ensure the transmission of force between the holding portion 330, the connecting assembly 300 and the infusion connector 100. Furthermore, the holding portion 330 is rigid, which is further convenient for the operator to use, i.e., when the operator grasps the holding portion 330, the lever portion 220 can also be grasped at the same time, and the process of clenching the palm is the process of controlling the lever assembly 200 to push the infusion connector 100 out of the infusion bottle 110, so that the application is easy to operate and convenient and practical.
[0048] It can be understood that the material of the holding portion 330 can be arbitrarily set, as long as the holding portion 330 is rigid and does not pollute the infusion system. In actual use, an anti-slip layer can be further provided on the outside of the holding portion 330 to avoid relative sliding between the hand of the operator and the holding portion 330 during use, which affects normal operation. Furthermore, the holding portion 330 is made of a rigid material, which can withstand multiple uses and cleaning. After use, the holding portion 330 can be easily sterilized and disinfected.
[0049] In an embodiment, as shown in Figure 1 , Figure 2As shown, the length of the grip portion 330 is L3, satisfying the following: L3 ≥ L2. The grip portion 330 is longer than the lever portion 220, providing the operator with more operating space. The longer grip portion 330 provides a larger lever arm, reducing the burden on the operator's hand. When applying force to the end of the lever portion 220 away from the hinge, the grip portion 330 supports the operator's palm, ensuring a stable grip on the infusion connector 100, preventing misoperation and direct contact between the infusion connector 100 and the operator or patient, thereby ensuring stability and safety for the operator when using this embodiment.
[0050] In one embodiment, for example, Figure 1 、 Figure 2 As shown, an opening is provided on the end of the abutting portion 210 close to the infusion bottle 110, and the opening is configured to allow the abutting portion 210 to approach the infusion bottle 110 without obstruction. The abutting portion 210 is provided with an opening, and the opening is connected to the clearance groove 230, so that the clearance groove 230 forms an open groove, and the connecting assembly 300 is disposed in the open groove. When the lever assembly 200 rotates, the connecting assembly 300 can pass through the opening at will, that is, the abutting portion 210 will not interfere with the connecting assembly 300 when rotating. During the process of pulling out the infusion connector 100, the abutting portion 210 will not interfere with the infusion connector 100, further ensuring the stability of this embodiment.
[0051] The present application also provides an infusion device, including a bracket and an infusion device according to any one of the above embodiments, wherein the infusion bottle 110 is hung on the bracket, and the infusion connector 100 is inserted into the infusion bottle 110 .
[0052] The infusion device of this embodiment includes the infusion device of any one of the above embodiments, and thus has all the beneficial effects of the above infusion devices, which will not be described in detail here.
[0053] It should be noted that, unless there is any conflict, the features in the embodiments of this application can be combined with each other.
[0054] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
