Description

Technical Field

[0001] This application relates to the technical field of medical devices, and particularly to a novel intelligent ceiling track infusion device. Background Art

[0002] Infusion devices are one of the common medical devices in hospitals, mainly used for hanging the infusion liquid to assist patients in receiving infusions. Among them, the ceiling track infusion device is an important part of the infusion device and is usually used in medical institutions such as hospitals, clinics, and nursing centers. It is an infusion rack suspended from the ceiling and can be moved to the required position through pulleys and steel wires, facilitating medical operations such as infusions and injections by doctors and nurses. The ceiling track infusion rack can save space, reduce obstacles on the ground, and improve the work efficiency and safety of medical institutions.

[0003] The Chinese Patent Network discloses "A Ceiling Track Infusion Rack" with the publication number CN209033357U, which includes a ceiling track, a slider, a fixed cylinder, a telescopic cylinder, a first fastening nut, a fixed ring, a hook, a heating rod, and a second fastening nut. The slider is slidably connected to the ceiling track, and the bottom of the slider is fixedly connected to the top of the fixed cylinder. The telescopic cylinder is inserted into the fixed cylinder from the bottom of the fixed cylinder. The lower end of the fixed cylinder is threadedly connected to the first fastening nut. A fixed ring is fixedly attached to the lower outer wall of the fixed cylinder. Hooks are evenly fixed around the fixed ring. The heating rod is inserted into the telescopic cylinder from the bottom of the telescopic cylinder. The lower end of the telescopic cylinder is threadedly connected to the second fastening nut. A storage battery is fixed to the bottom of the heating rod, and a knob switch is fixed to the storage battery. Electric heating wires are embedded inside the heating rod, and the storage battery, the knob switch, and the electric heating wires are sequentially connected through wires. A hollow belt is formed on the bottom plate of the ceiling track, and chutes are provided on the lower surface of the bottom plate on both sides of the hollow belt. The slider is integrally formed by an upper sliding plate, a connecting column, and a lower sliding plate. A ball fixed ring and a compression spring are sleeved on the connecting column. The bottom of the compression spring is fixedly connected to the lower sliding plate, and the top of the compression spring is fixedly connected to the ball fixed ring. A ball is embedded in the top of the ball fixed ring, and the upper half of the ball is embedded in the chute under the action of the compression spring and can slide in the chute. The upper sliding plate is located inside the ceiling track, and the bottom surface of the upper sliding plate is attached to the upper surface of the bottom plate of the ceiling track under the action of the compression spring. The length of this ceiling track infusion rack can be adjusted, facilitating medical staff to hang infusion bottles and adjust the height of the infusion bottles to control the infusion flow rate. The slider can be fixed at any position on the ceiling track, and the fixing is simple and reliable. The infusion rack uses a rigid connection rather than a hook-type docking, so the infusion rack will not shake around during infusion, affecting normal infusion. The heating rod can heat the liquid medicine flowing through the infusion tube. Compared with heating the liquid medicine in the bottle, the infusion tube is thinner and the liquid medicine is evenly heated. The heated liquid medicine has a shorter distance to flow into the patient's body, and less heat is lost during the process. The heating rod can be retracted into the telescopic cylinder when not in use, saving space.

[0004] In use, it is found that the hook of the existing ceiling rail infusion device protrudes in the idle state, which easily causes medical staff or patients to hit the hook, increasing the probability of injury to medical staff or patients. At the same time, it also increases the probability of damage to the ceiling rail infusion stand, which is not conducive to popularization and use. Summary of the Invention

[0031] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 ,In one or more embodiments, a novel intelligent overhead infusion device is provided, including a housing 100. A cavity 101 is formed inside the housing 100. A telescopic assembly and a connecting rod 102 are arranged inside the cavity 101. The telescopic assembly is used to drive the connecting rod 102 to change its height. The other end of the connecting rod 102 extends to the outside of the housing 100 and is connected to a fixed seat 103. A driving motor 104 is arranged inside the fixed seat 103. A groove 105 is formed inside the fixed seat 103. The output end of the driving motor 104 extends into the groove 105 and is connected to a fixed rod 106. The other end of the fixed rod 106 extends to the outside of the fixed seat 103 and is connected to a hook body 107. An installation plate 108 is arranged on the surface of the housing 100. Threaded installation holes 109 are formed inside the installation plate 108.

[0032] In this embodiment, the installation plate 108 is brought into contact with the corresponding position and installed by means of corresponding bolts through the threaded installation holes 109. In the idle state, the hook body 107 faces downward. When in use, the telescopic member drives the connecting rod 102 to change its height, and at the same time, after starting the driving motor 104, the hook body 107 is driven by the fixed rod 106 to change its angle until the hook body 107 becomes horizontal. By changing the direction of the hook body 107, the probability of impact on medical staff or patients is reduced, and the probability of personnel injury and equipment damage is effectively reduced.

[0033] Please refer to Figure 1 、Figure 2 , Figure 3 and Figure 4 , in some embodiments, the telescopic assembly includes a fixed housing 110. A through hole is provided inside the fixed housing 110, and the inner wall of the through hole is threadedly connected to the surface of the connecting rod 102. A bearing 111 is provided on the surface of the fixed housing 110, and the surface of the bearing 111 is connected to the inner wall of the cavity 101. A first bevel gear 112 is provided on the surface of the fixed housing 110. A telescopic motor 114 is provided inside the housing 100, and the output end of the telescopic motor 114 extends into the cavity 101 and is provided with a second bevel gear 113. The surface of the first bevel gear 112 meshes with the surface of the second bevel gear 113. A chuck 125 is provided at the top of the connecting rod 102 and above the fixed housing 110.

[0034] In this embodiment, after the telescopic motor 114 is started, the continuous meshing of the first bevel gear 112 and the second bevel gear 113 causes the fixed housing 110 to rotate. Under the action of the thread, the height of the connecting rod 102 is changed, eliminating the need for medical staff to pull, reducing the labor intensity of medical staff. The setting of the bearing 111 enables the fixed housing 110 to only rotate but not change in height. At the same time, a limiting groove 126 is provided inside the connecting rod 102, and a protrusion 127 is provided inside the cavity 101. The protrusion 127 is located in the limiting groove 126. This setting restricts the connecting rod 102 from rotating when the fixed housing 110 rotates, and thus the height can be changed. The chuck 125 is larger than the size of the fixed housing 110. Therefore, when the connecting rod 102 reaches the limit distance, the bottom of the chuck 125 contacts the top of the fixed housing 110.

[0035] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4, in some embodiments, one end of the hook body 107 passes through the surface of the fixing rod 106 and is provided with an abutting plate 115. A pressure sensor 116 is arranged inside the fixing rod 106. The pressure sensor 116 is used to monitor the force exerted by the abutting plate 115 on the fixing rod 106. A timer 117 is arranged inside the housing 100. A display screen 118 is arranged on the front surface of the fixed housing 110. Encoders 119 are arranged on both the telescopic motor 114 and the driving motor 104. A distance sensor 120 is arranged inside the housing 100. A warning lamp 121 is arranged on the front surface of the fixed housing 110. A controller 122 is arranged inside the housing 100. The driving motor 104, the telescopic motor 114, the distance sensor 120, the pressure sensor 116, the timer 117, the display screen 118, the encoder 119 and the warning lamp 121 are all electrically connected to the controller 122. It further includes a terminal, and the terminal includes a display and a wireless communicator. The display and the wireless communicator are electrically connected. The controller 122 and the wireless communicator are communicatively connected. A battery 123 is arranged inside the housing 100. The battery 123 is used to supply power to the driving motor 104, the telescopic motor 114, the distance sensor 120, the pressure sensor 116, the timer 117, the display screen 118, the encoder 119, the warning lamp 121 and the controller 122. A charging hole 124 is formed on the surface of the housing 100.

[0036] In this embodiment, when hanging an infusion bottle or infusion bag in the horizontal state of the hook body 107, a certain force will be applied to the hook body 107, and at the same time, the abutting plate 115 will be driven to apply the same force to the pressure sensor 116. Therefore, the pressure sensor 116 can monitor the pressure change. The data detected by the pressure sensor 116 will be transmitted to the controller 122, and the display screen 118 will display the pressure. At the same time, the data will be sent to the wireless communicator and displayed through the display. When the data monitored by the pressure sensor 116 is lower than the set threshold, it indicates that the infusion bottle or infusion bag has been emptied. Furthermore, a warning light 121 can emit light for display. The timer 117 monitors the working duration of the driving motor 104 and the telescopic motor 114. When the duration is fixed and the rotation speed is fixed, the rotation angle of the fixed rod 106 is fixed. At the same time, when the pressure sensor 116 does not change pressure within the set time and the pressure value is the pressure when no infusion bag or infusion bottle is hung, the telescopic motor 114 is started at this time. Through the continuous meshing of the first bevel gear 112 and the second bevel gear 113, the fixed housing 110 rotates in the opposite direction, and then the connecting rod 102 is retracted into the cavity 101 to reduce the interference to personnel in the restricted state. The encoder 119 can monitor the rotation angle, number of rotations, and rotation speed of the driving motor 104 and the telescopic motor 114. The distance sensor 120 can monitor the distance between the connecting rod 102. The distance change indicates the length of the connecting rod 102 extending outside the housing 100. When the bottom of the chuck 125 contacts the top of the fixed housing 110, it indicates the maximum extension length of the connecting rod 102. At this time, it is the maximum threshold monitored by the distance sensor 120. When the maximum threshold is reached, the warning light 121 can emit light for reminder. The battery 123 is used to supply power to the driving motor 104, the telescopic motor 114, the distance sensor 120, the pressure sensor 116, the timer 117, the display screen 118, the encoder 119, the warning light 121, and the controller 122, and the charging hole 124 can charge the battery 123; it should be noted that the warning light 121 is used in two states and is distinguished by displaying different lights.

[0037] It should be noted that the specific model specifications of the battery 123, the driving motor 104, the telescopic motor 114, the distance sensor 120, the pressure sensor 116, the timer 117, the display screen 118, the encoder 119, the warning light 121, and the controller 122 in this disclosure need to be selected according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail; its power supply and principle are clear to those skilled in the art and will not be described in detail here; the connection and installation of each part and the signal transmission principle belong to the well-known technology in this field.

[0038] Specifically, the working principle of a novel intelligent ceiling rail infusion device provided by this application is as follows:

[0039] Contact the installation disc 108 with the corresponding position and install it through the threaded installation holes 109 with the corresponding bolts. In the idle state, the hook body 107 faces downward.

[0040] After starting the telescopic motor 114 in the working state, the first bevel gear 112 and the second bevel gear 113 continuously mesh, causing the fixed housing 110 to rotate. Under the action of the thread, the height of the connecting rod 102 changes. At the same time, after starting the driving motor 104, the hook body 107 is driven by the fixed rod 106 to change the angle until the hook body 107 becomes horizontal.

[0041] Medical staff hang the infusion bottle or infusion bag on the hook body 107. At this time, a certain force is applied to the hook body 107, and at the same time, the abutting plate 115 is driven to apply the same force to the pressure sensor 116. Therefore, the pressure sensor 116 can monitor the pressure change. The data detected by the pressure sensor 116 will be transmitted to the controller 122, and the display screen 118 will display the pressure. At the same time, the data will be sent to the wireless communicator and displayed through the display. When the data monitored by the pressure sensor 116 is lower than the set threshold, it indicates that the infusion bottle or infusion bag has completed the infusion, and then the warning light 121 can emit light for display.

[0042] The timer 117 monitors the working duration of the driving motor 104 and the telescopic motor 114. When the duration is fixed and the rotation speed is fixed, the rotation angle of the fixed rod 106 is fixed. At the same time, when the pressure sensor 116 does not change the pressure within the set time and the pressure value is the pressure when no infusion bag or infusion bottle is hung, the telescopic motor 114 is started at this time. Through the continuous meshing of the first bevel gear 112 and the second bevel gear 113, the fixed housing 110 rotates in the opposite direction to retract the connecting rod 102 into the cavity 101 to reduce the interference to personnel in the restricted state.

[0043] The distance sensor 120 can monitor the distance between the connecting rod 102. The distance change indicates the length of the connecting rod 102 extending outside the housing 100. When the bottom of the chuck 125 contacts the top of the fixed housing 110, it indicates the maximum extension length of the connecting rod 102. At this time, it is the maximum threshold monitored by the distance sensor 120. When the maximum threshold is reached, the warning light 121 can emit light for reminder.

[0044] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
