Detailed Description
The invention is further illustrated by the following examples in conjunction with the accompanying drawings: the backflow-preventing atomizer rack as shown in fig. 1-6 comprises a bracket body 1, a bracket barrel 2 and a timing voice alarm 3; the structure and layout of the various parts can be clearly seen in the embodiment of fig. 1.
The bracket body 1 comprises a bedside upright rod 4, a yaw rod 5, a suspender 6 and a support barrel transverse supporting rod 7; the height of the bedside upright rod 4 is 30-90 cm, the length of the swaying rod 5 is 30-70 cm, the height of the suspender 6 is 15-50 cm, and the length of the supporting cylinder transverse supporting rod 7 is 5-20 cm; the top end of the bedside upright rod 4 is rotationally connected with the inner end of the yaw rod 5 through a horizontal rotary bearing, the outer end of the yaw rod 5 is vertically and fixedly connected with the top end of the suspender 6 or integrally arranged, and the bottom end of the suspender 6 is rotationally connected with the outer end of the supporting cylinder transverse supporting rod 7 through a horizontal rotary bearing; the inner end of the supporting cylinder transverse supporting rod 7 is vertically and fixedly connected with the outer wall of the vertically arranged supporting cylinder 2; as can be seen from fig. 1, the bedside upright 4 and the yaw bar 5 and the hanger rod 6 and the supporting tube transverse supporting bar 7 are connected by adopting rotary bearings, so that the supporting tube 2 is convenient to adjust to the front upper part of the face of a patient at the beginning, and the supporting tube 2 can follow movement when the patient swings slightly in use. The structural support can enable the atomizer bottle to be in a suspended vertical state all the time, and does not occupy the bed surface. Meanwhile, the patient lying in bed does not need to worry about the backflow of the liquid medicine into the mask, so that the serious problem possibly caused by the fact that the patient lying in bed can move slightly in the atomization treatment time to cause the pouring of the atomization bottle and the backflow of the liquid in the breathing circuit tube into the air tube can be solved practically.
The bedside upright rod 4, the suspender 6 and the transverse swinging rod 5 are telescopic rods. As can be seen in the embodiment of FIG. 1, the telescoping rod design is employed so that the height of the frame and the radius of extension can be adjusted to the needs of different patients. Wherein, the ball used for reducing the expansion resistance is embedded in the expansion part of the transverse swinging rod 5. The yaw rod 5 can easily and automatically adapt to the change of external force to expand and contract the length under the cooperation of the rotating bearing, so that a larger degree of freedom of movement is provided for a patient. The patient does not feel stressed when doing small-range head movements, and the restriction feeling brought to the patient is greatly reduced.
The connecting tube 17 is a flexible and variable length bellows. As can be seen in fig. 4 and 1, the bellows facilitates adjustment of the angle of the mask face, allowing the patient's head to move more freely.
The support cylinder 2 comprises a lower cylinder body 8 and an upper cylinder cover 9; a sealing plate 10 is arranged at the bottom end of the lower cylinder body 8, a transverse groove 11 penetrating up and down is formed in the center of the sealing plate 10 towards the bed head along a radial line, a vertical groove 12 penetrating through the outer end of the transverse groove 11 is formed in the wall of the lower cylinder body 8, and the vertical groove 12 and the transverse groove 11 are used for penetrating an oxygen pipe 14 connected with the bottom end of an atomizer bottle 13 arranged in the support cylinder into the cylinder body; the structure of the support cylinder 2 can be seen in fig. 2 and 3, and the oxygen tube 14 at the bottom end of the atomizer bottle 13 can be penetrated into the cylinder body through the vertical groove 12 and the horizontal groove 11, and then the atomizer bottle 13 is placed into the support cylinder 2.
The lower part of the upper cylinder cover 9 is embedded in the upper cylinder opening of the lower cylinder 8; a pair of vertical through grooves 15 are formed in the cylinder walls on the two sides of the upper cylinder cover 9 in a radial opposite manner, the lower end opening of each through groove 15 is formed in the bottom end opening edge of the upper cylinder cover 9, and the through grooves 15 are used for allowing a connecting pipe 17 between the atomizer bottle 13 and the mask 16 to pass through; as can be seen from fig. 3, the through grooves 15 are radially and oppositely opened with a pair of openings at the lower end, and the structure is a convenient hand-pinching clamping sleeve structure which is convenient for pinching the two sides of the through groove 15 of the upper cylinder cover 9 by hand, and is plugged into and embedded into the cylinder mouth of the lower cylinder body 8 after slight deformation.
The embedding part of the upper cylinder cover 9 and the lower cylinder 8 is provided with a nesting structure 18 which is convenient for the upper cylinder cover 9 to rotate around the lower cylinder 8; the nested structure 18 comprises an annular groove 19 annularly arranged on the upper inner wall of the lower cylinder 8, and an annular fillet 20 matched with the annular groove 19 and arranged on the lower outer wall of the upper cylinder cover 9. As can be seen from fig. 2 and 3, after the upper cylinder cover 9 and the lower cylinder 8 are covered, the annular molding 20 is embedded in the annular groove 19, a plurality of balls for reducing the rotation resistance are embedded between the annular molding 20 and the annular groove 19, and the upper cylinder cover 9 can rotate by guiding of the annular groove 19, and the purpose thereof is that: when the patient wears the mask and tightens the mask with the strap, the patient may swing a small amount during use, and as can be seen from the construction of the nebulizer of fig. 4 and the embodiment of fig. 1, the mask 16 swings with the connecting tube 17, and the connecting tube 17 forces the upper cylinder cover 9 to rotate.
The lower outer wall of the upper cylinder cover 9 is provided with a blocking edge 21 in a surrounding manner, and is used for abutting against the top end edge of the lower cylinder 8 when the upper cylinder cover 9 and the lower cylinder 8 are covered. As can be seen from fig. 2 and 3, the blocking edge 21 is provided in a position which is convenient for closing the cap tightly, and is convenient for rotating the upper cylinder cap 9.
The timing voice alarm 3 is arranged on the top panel of the upper cylinder cover 9 and is used for timing control and voice reminding a nurse of finishing atomization through a control circuit. As can be seen from fig. 1, the timing voice alarm 3 is provided on the top panel of the upper cylinder cover 9, so that the vision is clear, and at the same time, the upper cylinder cover 9 can be removed, thereby facilitating the time setting.
The timing voice alarm 3 comprises a built-in battery, a digital display time relay 22, a loudspeaker 23, a power switch 24 and a voice playing controller 25; the power switch 24 is connected in series with the direct current power supply and then provides power for the digital display time relay 22 and the voice playing controller 25; the input control TG end of the voice playing controller 25 is connected with the positive electrode of the power supply through a normally open switch at the output end of the digital display time relay 22, and is used for obtaining a high-level trigger signal by the control TG end of the voice playing controller 25 after the digital display time relay 22 is triggered; the output OUT terminal of the voice play controller 25 is connected to the speaker 23. In the circuit embodiment of fig. 6, the connection relation of the parts can be seen, the time is set by the digital display time relay 22, and the loudspeaker 23 is used for sounding an alarm. The digital display time relay 22 is essentially a time switch, and may be replaced with a similar time switch.
As a preferable solution, the main control chip of the voice playing controller 25 is HFC9561. Because the structure of the circuit can be changed differently, for example, a logic circuit or a singlechip is used for realizing the same function, the invention provides the thought of automatic voice reminding, thereby enabling atomization treatment to be more reliable and automatic.
The above-listed embodiments are for convenience of explanation, and are not limited thereto in practical use, and different embodiments may be used in cross combination.
