Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a humidification tank installation structure for respiratory equipment. Background Art

[0002] A humidification system can be used to treat patients who require respiratory assistance. A typical humidification system usually includes a gas source (a ventilator or oxygen generator, etc.), a humidification device, and a delivery pipeline. The humidification device includes a humidification tank, which first generates water vapor by heating the water in the humidification tank. The water vapor is then mixed with the gas passing through the humidification tank to humidify the gas. The humidified gas is finally delivered to the patient through a delivery pipeline.

[0003] The humidifier tank usually needs to be removably installed on the humidifier device. When the installed humidifier tank is connected to the airway of the humidifier device, the bottom is completely fitted with the heating plate on the heating base of the humidifier device. A spring is provided at the bottom of the heating base to apply an upward thrust to the humidifier tank through the heating plate to ensure the stability of the connection between the humidifier tank and the humidifier device. In addition, a floating baffle is provided on the heating base. When the humidifier tank is initially installed, the floating baffle can be pressed down to move the humidifier tank to the heating base. After the humidifier tank is installed in place, the floating baffle can be restored to its original position and limit the humidifier tank from moving outward. However, it is found in actual use that due to the gap between the floating baffle and the humidifier tank, when the humidifier device in use is moved, although the humidifier tank will not move out, it will cause problems such as tilting and loosening, which will reduce the airtightness of the airway connection of the device and affect the fit between the humidifier tank and the heating base, thereby reducing the accuracy of the temperature and humidity of the gas discharged from the humidifier tank, and ultimately reducing the stability and safety of the humidifier equipment.

[0046] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0047] like Figures 1 to 14 As shown, the utility model comprises a humidification tank body 3, a heating plate, a heating plate base 4, a floating baffle 1, a seesaw 5, a limit mounting seat 7 and a limit assembly 2, wherein the heating plate is elastically mounted on the heating plate base 4, and as shown Fig.10 As shown, the heating plate base 4 and the limit mounting seat 7 are both arranged in the housing of the device host 17. Figure 2 As shown, the limit mounting seat 7 is arranged on one side above the heating plate base 4. Figure 1 As shown, the middle part of the seesaw 5 is rotatably mounted on one side of the heating plate base 4 through a rotating shaft 501, and a floating baffle 1 that can be raised and lowered is provided on the outer side of the heating plate base 4, and a baffle pressing block 101 is provided on the floating baffle 1 to abut against the outer end of the seesaw 5, and the limit assembly 2 is arranged in the limit mounting seat 7, and as shown Figures 3 to 5 As shown, the limit assembly 2 includes a liftable L-shaped floating limit rod 201. Figures 11 to 14 As shown, a locking portion 8 is provided at the upper end of the humidification tank body 3, and the horizontal rod portion 2011 at the upper end of the L-shaped floating limit rod 201 cooperates with the locking portion 8, the vertical rod portion 2012 of the L-shaped floating limit rod 201 can be raised and lowered in the limit mounting seat 7, and a lower push rod 203 is provided at the lower end of the vertical rod portion 2012, and the lower push rod 203 passes through the limit mounting seat 7 and abuts against the inner end of the rocker 5.

[0048] like Figures 11 to 14As shown, when the utility model is working, when the floating baffle 1 is pressed down, the baffle pressing block 101 of the floating baffle 1 presses the outer end of the seesaw 5 downward, and makes the inner end of the seesaw 5 rotate counterclockwise upward to lift the L-shaped floating limit rod 201. After the L-shaped floating limit rod 201 is lifted, the humidification tank body 3 can be moved in. When the humidification tank body 3 is moved into place, as shown in FIG. Figures 13-14 As shown, after the operator releases the floating baffle 1, the floating baffle 1 automatically rises to a limit position, and the inner end of the seesaw 5 also automatically drops to return to its original position. At this time, the horizontal rod 2011 falls on the outside of the locking portion 8 and abuts against it to limit the displacement of the humidification tank body 3. In this way, the upper and lower ends of the humidification tank body 3 have limiting structures, thereby ensuring that the humidification tank body 3 can be firmly connected to the equipment host 7 without tilting or loosening.

[0049] like Figures 3 to 5 As shown, in this embodiment, the limit mounting seat 7 is provided with a lifting guide portion 701, a spring limiting surface 702, a spring accommodating cavity 703 and a lower end plate 704 from top to bottom, wherein the vertical rod portion 2012 of the L-shaped floating limit rod 201 is sleeved with a spring 202, and the spring 202 is arranged in the spring accommodating cavity 703, and a spring limiting surface 702 is formed at the connection between the lifting guide portion 701 and the spring accommodating cavity 703, a connecting block 2031 is provided at the upper end of the lower push rod 204 and is threadedly connected to the lower end of the vertical rod portion 2012, and the spring 202 is arranged between the spring limiting surface 702 and the connecting block 2031, and the lower end of the lower push rod 204 passes through the lower end plate 704. The lifting guide portion 701 is provided with a through hole for the vertical rod portion 2012 to pass through. In addition, the lower push rod 204 can be disassembled and replaced with a suitable length according to actual needs to ensure the limiting function of the L-shaped floating limit rod 201 and will not affect the entry and exit of the humidification tank body 3. After the lower push rod 204 is disassembled, the spring 202 can also be replaced.

[0050] like Figures 1 to 5 As shown, in this embodiment, a limiting groove 705 is provided at the upper end of the lifting guide portion 701, and the horizontal rod portion 2011 of the L-shaped floating limiting rod 201 is provided in the limiting groove 705, and the limiting groove 705 can prevent the horizontal rod portion 2011 from horizontally deflecting.

[0051] The upper surface of the heating plate base 4 is provided with a heating plate, and the heating plate can be supported and installed in the heating plate base 4 by elastic elements such as springs. After the humidification tank body 3 is moved onto the heating plate, the elastic force of the elastic element can support the humidification tank body 3 through the heating plate to ensure the connection stability between the humidification tank body 3 and the main unit of the humidification device. This is a well-known technology in the art. Figures 11 to 14As shown, in this embodiment, the engaging portion 8 includes a vertical limiting surface 802 and an inclined surface 801, wherein when the humidification tank body 3 is installed in place, the horizontal rod portion 2011 of the L-shaped floating limiting rod 201 abuts against the vertical limiting surface 802 to limit the displacement of the upper end of the humidification tank body 3. When the humidification tank body 3 is moved out, the horizontal rod portion 2011 at the upper end of the L-shaped floating limiting rod 201 can move downward along the inclined surface 801, which can push the L-shaped floating limiting rod 201 to fall, and avoid the noise caused by the falling of the L-shaped floating limiting rod 201.

[0052] like Figures 1-2 and Figures 6-7 As shown, the outer side of the heating plate base 4 is provided with a base outer shell 401, and the floating baffle 1 is overall L-shaped and buckled on the upper side of the base outer shell 401. The utility model can select a suitable floating baffle 1 structure according to actual needs, wherein Figure 8 and Figure 8a As shown, in one embodiment of the utility model, a first connecting seat 402 is provided on the bottom surface of the base shell 401, a second connecting seat 11 is provided on the lower side of the floating baffle 1, and the first connecting seat 402 and the second connecting seat 11 are connected by screws 9, and the screws 9 can be plug screws, and a support spring 10 is sleeved on the outer side of the screws 9, and the lower end of the support spring 10 abuts against the upper end surface of the first connecting seat 402, and the upper end of the support spring 10 abuts against the inner wall of the upper side of the floating baffle 1, as shown in FIG. Figure 8a As shown, when the floating baffle 1 is pressed, the floating baffle 1 compresses the supporting spring 10 , and when the floating baffle 1 is released, the floating baffle 1 automatically resets under the action of the supporting spring 10 .

[0053] like Fig. 9 As shown, in another embodiment of the utility model, the floating baffle 1 can adopt a supporting structure with a self-locking function to achieve floating lifting, and the supporting structure includes a pressure rod 12, a self-locking structure 13, a movable rod 14 and other structures, wherein the pressure rod 12 is arranged on the lower side of the floating baffle 1, the movable rod 14 is arranged in the first connecting seat 402, and an movable rod spring 15 is arranged on the lower side of the movable rod 14. This structure is a prior art, which is the same as the existing ballpoint pen main body structure. For example, the structure in the authorization announcement number CN201201428Y can be adopted, such as Fig.15As shown, the ballpoint pen body in the patent includes a pressing piece A1 (equivalent to the pressing rod 12), a rotating wheel A2 (equivalent to the movable rod 14), a spring A3 and other structures, wherein, referring to the description starting from the end of page 3 of the patent specification, when the pressing piece A1 is pressed downward under the action of an external force (equivalent to pressing the floating baffle 1 to press the pressing rod 12 downward), the rotating wheel A2 presses the ballpoint pen core downward while rotating the rotating wheel A2 itself rotates a certain angle, releasing the pressing piece A1, and the rotating wheel A1 just presses against the plane formed by the lower ends of the multiple convex strips, so that the pen tip of the ballpoint pen core can be extended out of the pen barrel, and at the same time, the pressing piece A1 together with the rotating wheel Wheel A2 is actually also in a descending state (equivalent to the pressure rod 12 and the floating baffle 1 being in a descending state and locked). When the pressure piece A1 is pressed down again (i.e., the floating baffle 1 is pressed down again), the rotating wheel A2 rotates a certain angle again, releasing the pressure piece A1, and the rotating wheel A2 just retracts from the gap between the multiple convex strips. At this time, the ballpoint pen core is retracted into the pen barrel under the action of the spring A3 (equivalent to the movable rod spring 15). At the same time, the pressure piece A1 and the rotating wheel A2 are in an ascending state (equivalent to the pressure rod 12 and the floating baffle 1 being unlocked and ascended). The above-mentioned multiple convex strips and other structures are the self-locking structure 13.

[0054] like Figures 1 to 4 as well as Fig.10 As shown, two humidifier tank elbows 6 are provided at the upper end of the humidifier tank body 3, one of which faces outward and is connected to the heated breathing pipeline 16, and the other faces inward and is connected to the corresponding pipeline in the device host 17.

[0055] The working principle of the utility model is:

[0056] like Figures 11 to 14 As shown, when the utility model is working, after the operator presses down the floating baffle 1, the floating baffle 1 no longer plays a blocking role. At this time, the operator can send the humidification tank body 3 to the heating plate on the upper surface of the heating plate base 4. The heating plate can be supported and installed in the heating plate base 4 by elastic elements such as springs, and when the humidification tank body 3 is placed in, the elastic force of the elastic element can also support the humidification tank body 3 through the heating plate. When the humidification tank body 3 is installed in place, the operator releases the floating baffle 1, and the floating baffle 1 automatically rises and blocks the humidification tank body 3 to prevent it from moving outward.

[0057] In addition, when the floating baffle 1 is pressed down, Fig.11 As shown, the baffle pressing block 101 of the floating baffle 1 presses the outer end of the seesaw 5 downward, and makes the inner end of the seesaw 5 rotate counterclockwise upward to lift the L-shaped floating limit rod 201. After the L-shaped floating limit rod 201 is lifted, it will not affect the movement of the humidification tank body 3 in or out. When the humidification tank body 3 is moved into place, Figures 13-14As shown, after the operator releases the floating baffle 1, the floating baffle 1 automatically rises to limit the displacement of the lower end of the humidification tank body 3, and the inner end of the seesaw 5 also automatically drops to return to its original position. At this time, the horizontal rod 2011 falls on the outside of the locking portion 8 and abuts against it to limit the displacement of the upper end of the humidification tank body 3. In this way, the upper and lower ends of the humidification tank body 3 are both limited, and the upward supporting elastic force applied by the elastic element on the lower side of the heating plate can fully ensure that the humidification tank body 3 can be firmly connected to the equipment host without tilting or loosening, and ensure the sealing of the pneumatic connection of the device and the fit between the humidification tank body and the heating base, thereby ensuring the temperature and humidity of the output humidified gas.
