The inventor of the present application has found that existing medical instruments include a display screen, a battery, a heat sink, and other functional modules, which are heavy overall. However, the handle of the medical instrument is directly fixed to the housing, and there is a risk that the handle falls off due to the breakage of the housing.

In order to improve at least part of the technical problems, the application provides a medical instrument and a medical system which can improve the connection strength of a handle, and avoid the phenomenon that the handle of the medical instrument falls off. The medical system and the medical instrument thereof provided by the application are described in detail below with reference to the detailed description and the accompanying drawings.

Referring to fig. 1 and 2, a medical system 100 according to an embodiment of the present application includes a medical instrument 200 and a fixing assembly 300, wherein the fixing assembly 300 is fixedly connected to the medical instrument 200 and can be fixed to a medical instrument 400. The medical instrument 200 is detachably mounted on the medical instrument 400 through the fixing assembly 300, so that the medical instrument 200 is convenient to use and is suitable for different application scenes. Medical instrument 200 is a mobile, portable instrument suitable for use fixed to medical instrument 400, which may be, but is not limited to, a console, a monitor, a ventilator, or the like. The medical apparatus 400 serves to mount, support, etc. the medical instrument 200, which may be an infusion rod, hospital bed, operating table or other medical support, etc., and is not limited to the list. It is understood that the medical device 400 may include a rod structure, a column structure, or a tube structure, etc., sufficient to mount, support, and/or support the medical instrument 200.

Referring to fig. 3-5, the medical instrument 200 includes a housing 210, a handle 220, and a fastener 230. The housing 210 is provided with an accommodating space 211. The fixing member 230 is disposed in the accommodating space 211 and connected to the housing 210, wherein the tensile strength of the fixing member 230 is greater than that of the housing 210. Handle 220 is disposed through housing 210 and is coupled to fastener 230. By arranging the fixing member 230 in the accommodating space 211 of the housing 210 and penetrating the handle 220 into the housing 210 to connect the fixing member 230, the tensile strength of the fixing member 230 is greater than that of the housing 210, thereby avoiding the falling-off phenomenon of the handle 220 caused by fracture due to insufficient tensile strength of the housing 210 and improving the structural stability of the medical instrument 200 and the medical system 100.

In this embodiment, the tensile strength of the housing 210 is 32-60MPa and the tensile strength of the fixing member 230 is 270-460MPa. More specifically, the tensile strength of the shell is 40-50MPa, and the tensile strength of the fixing piece is 300-350MPa. For example, the housing 210 may be made of plastic material, such as ABS (Acrylonitrile butadiene Styrene copolymers, acrylonitrile butadiene styrene) plastic, etc., and the fixing member 230 may be made of metal material, such as cold-rolled steel plate, etc. The material of the housing 210 is not limited to plastic, and the material of the fixing member 230 is not limited to metal, so long as the requirement that the tensile strength of the fixing member 230 is greater than that of the housing 210 can be satisfied.

Referring to fig. 6, the fixing member 230 includes a connection top 231, a support side 232, and a connection bottom 233 connected in sequence, wherein the connection top 231 and the connection bottom 233 are connected to the same side of the support side 232, the connection top 231 is connected to the handle 220, and the support side 232 and the connection bottom 233 are connected to the housing 210. Since the handle 220 is coupled to the coupling top 231 of the fixing member 230 and the supporting side 232 and the coupling bottom 233 of the fixing member 230 are coupled to the housing 210, that is, the handle 220 is indirectly coupled to the housing 210 through the fixing member 230, the handle 220 can lift the housing 210 and other structures inside thereof through the fixing member 230 when the handle 220 is operated, and the coupling strength between the fixing member 230 and the housing 210 is improved through the coupling between the supporting side 232 and the coupling bottom 233 and the housing 210.

The mount 230 further includes a first stiffening portion 234 and a second stiffening portion 235. The first reinforcing portion 234 is provided at the inner side of the junction of the connection top 231 and the support side 232, and reinforces the connection strength between the connection top 231 and the support side 232, improving the support performance of the fixing member 230. The second reinforcement 235 is provided at the inner side of the junction of the connection bottom 233 and the support side 232 to reinforce the connection strength between the connection bottom 233 and the support side 232, which cooperates with the first reinforcement 234 to improve the structural strength of the fixing member 230 as a whole.

It should be noted that, in other embodiments, the connection top 231 and the support side 232 have an included angle therebetween, and the included angle may be variable, so that the connection top 231 can selectively abut against or separate from the housing 210. Since the reinforcing part is not arranged on the inner side of the joint of the connecting top 231 and the supporting side 232, the included angle between the connecting top 231 and the supporting side 232 is variable, when a user lifts the handle 220, the connecting top 231 rotates relative to the supporting side 232, so that the included angle between the connecting top 231 and the supporting side 232 is increased, and the connecting top 231 is propped against the top of the shell 210, and the shell 210 can stop the connecting top 231 to support the lifting operation of the user, so that the overlarge rotation angle of the connecting top 231 relative to the supporting side 232 is avoided, and the lifting stability of the handle 220 can be improved; when the user releases the handle 220, the included angle becomes smaller, so that the connection top 231 is separated from the top of the housing 210, and the handle 220 is driven to retract relative to the housing 210, so that the handle 220 is "hidden", i.e. the handle 220 can be blocked in the front view direction of the medical instrument 200 by matching with other structures of the housing 210 or other structures of the medical instrument 200, so that the appearance of the medical instrument 200 is more concise and attractive. In this embodiment, the top surface of the connection top 231 can be abutted against the inner surface of the housing 210, i.e. when the connection top 231 is abutted against the top of the housing 210, the top surface of the connection top 231 is abutted against the bottom surface of the top of the housing 210, i.e. the connection top 231 is in surface contact with the top of the housing 210, so as to realize stable abutment of the fixing piece 230 and the housing 210, and further improve the lifting stability of the handle 220. In addition, because the top 231 of the connection is in surface contact with the top of the housing 210, the top surface of the housing 210 has an increased stress area, so that the stress on the housing 210 when the handle 220 is pulled is reduced, and the structural stability of the housing 210 is ensured.

In the fixing member 230, the connection top 231 is provided with a first screw column 231a, and the first screw column 231a is provided with a first screw hole (not shown), and the handle 220 may be fixed to the connection top 231 by being fixedly coupled to the first screw hole by a screw or a stud. The support side 232 is provided with a dodging hole 236, the dodging hole 236 is used for dodging an installation table on the corresponding side of the housing 210, and the installation table is used for installing a loudspeaker of the medical instrument 200. The two sides of the avoidance hole 236 of the support side 232 are also provided with avoidance areas 237, and the avoidance areas 237 are in a notch shape and are used for avoiding the heat dissipation holes 212 on the corresponding side of the shell 210, so that the support side 232 is prevented from blocking the heat dissipation air flow from the heat dissipation holes 212. The support side 232 is further provided with a second screw column 232a, and the second screw column 232a is provided with a second screw hole (not shown), so that the fixing component 300 is fixedly connected to the fixing member 230 through the corresponding side portion of the screw penetrating the housing 210 and the second screw hole, and is not directly fixed to the housing 210 of the medical instrument 200, and the tensile strength of the fixing member 230 is greater than that of the housing 210, so that the phenomenon that the fixing component 300 falls off due to the breakage of the housing 210 is avoided, and the structural stability of the medical instrument 200 and the medical system 100 is further improved. The connection bottom 233 is provided with a third screw column 233a, and a third screw hole (not shown) is provided in the third screw column 233 a.

The fixing member 230 can enhance the connection strength between the fixing member and the housing 210 through the bottom connecting member 240, and the handle 220 can further enhance the connection strength between the fixing member 230 and the housing 210 through the bottom connecting member 240, so as to better lift the housing 210 and other structures inside the housing. Moreover, the fixing member 230 and the bottom connecting member 240 enhance the support of the outer case 210.

Since the angle θ between the side plate 242 and the bottom plate 241 of the bottom connector 240 is acute (as shown in fig. 7), the side plate 242 may serve as a support, i.e., the side plate 242 may support a structural member when the structural member is mounted on the side plate 242.

The bottom connector 240 further includes a third reinforcement portion 243, the third reinforcement portion 243 being disposed at an inner side of a joint of the bottom plate 241 and the side plate 242, the third reinforcement portion 243 reinforcing a connection strength between the bottom plate 241 and the side plate 242, and the side plate 242 being supported by the third reinforcement portion 243 with a better supporting effect.

The bottom plate 241 is provided with a first connection hole (not shown), which is provided corresponding to the third screw column 233a of the connection bottom 233 of the fixing member 230, and screws sequentially pass through the third screw hole and the first connection hole from top to bottom, thereby achieving the fixed connection between the fixing member 230 and the bottom connection member 240.
