Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a condensate collection device for anesthesia oxygen inhalation devices. Background Technology

[0002] In clinical treatment, oxygen therapy is one of the important treatment methods for many patients. Oxygen is delivered to each bedside in the ward via tubing from the hospital's oxygen supply station. The oxygen stored in the oxygen supply station is mostly liquid oxygen, which needs to be vaporized into gas before being transported. However, the vaporization of liquid oxygen produces a low-temperature gas, which keeps the oxygen in the tubing at a low temperature during transmission. When the low-temperature oxygen passes through the oxygen cylinder, it significantly lowers the temperature of the outer wall of the cylinder, resulting in a large temperature difference between the outer wall of the cylinder and the surrounding environment.

[0003] However, this temperature difference causes condensation to continuously form on the outer surface of the oxygen cylinder, which drips onto the hospital bed or bedside table. This not only increases the workload for medical staff but also causes discomfort to patients, and may even wet their clothes, affecting their treatment experience and comfort. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a condensate collection device for anesthesia oxygen inhalation devices, solving the technical problem of condensate dripping.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a condensate collection device for an anesthesia oxygen inhalation device, comprising:

[0006] The casing has a hollow cylindrical structure with an opening at the top and a drainage chamber at the bottom;

[0007] An elastic water reservoir, which is deformably and elastically suspended on the inner top wall of the casing and maintains a radial gap with the inner wall of the casing;

[0008] A fixing ring is attached to the bottom of the elastic water reservoir and covers at most one-third of its circumferential area;

[0009] Extrusion plates, multiple extrusion plates are arranged in a ring array inside the housing. The radial outer side of each extrusion plate is initially in contact with the inner wall of the housing, and a drainage channel is formed between adjacent extrusion plates.

[0010] The linkage connects the fixed ring and each extrusion plate, converting the axial displacement of the fixed ring into the radial centripetal motion of the extrusion plates;

[0011] The elastic water reservoir, upon absorbing water and increasing its weight, drives the fixed ring to move axially downwards. This, in turn, forces the extrusion plates to contract radially synchronously via a linkage, thereby achieving the following:

[0012] The extrusion surface of the extrusion plate gradually compresses the saturated area of ​​the elastic water reservoir, forcing the condensate to drain out;

[0013] The drainage channel gradually narrows as the extrusion plate moves centripetally, creating a pulse-like drainage effect.

[0014] Preferably, the contact area between the extrusion surface of the extrusion plate and the elastic water reservoir exhibits a progressive compression relationship.

[0015] Preferably, the extrusion surface of the extrusion plate is provided with a corrugated guide groove, the groove depth of which decreases along the drainage direction, generating eddy current disturbance during the pulse drainage stage to promote drainage.

[0016] Preferably, after the elastic water reservoir is drained, it elastically rebounds, causing the fixed ring to move upward and reset. Simultaneously, the linkage releases the radial constraint on the extrusion plate, allowing the extrusion plate to reset to its initial state.

[0017] Preferably, the elastic water reservoir is a sponge structure with gradient porosity, wherein the porosity of the region near the inner wall of the casing is less than that of the central region, forming a capillary adsorption force distribution that gradually changes from the inside to the outside.

[0018] By means of the above technical solution, this utility model provides a condensate collection device for anesthesia oxygen inhalation equipment, which has at least the following beneficial effects:

[0019] This utility model's elastic water reservoir, after gaining weight, drives the extrusion plate through a linkage to generate radial centripetal motion, thereby continuously and effectively extruding and discharging condensate. This not only effectively prevents condensate accumulation but also enhances the drainage effect through a pulse-type drainage method, ensuring that the device can maintain efficient operation during long-term work and further improving patient comfort.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please refer to Figures 1-3 This embodiment proposes a condensate collection device for an anesthesia oxygen inhalation device, comprising:

[0027] The cover 1 has a hollow cylindrical structure with an opening at the top and a drainage chamber at the bottom;

[0028] The elastic water storage body 2 is deformably and elastically suspended on the inner top wall of the casing 1 and maintains a radial gap with the inner wall of the casing 1;

[0029] The elastic water storage body 2 is a sponge structure with gradient porosity. The porosity of the area near the inner wall of the cover 1 is smaller than that of the central area, forming a capillary adsorption force distribution that gradually changes from the inside to the outside.

[0030] A fixing ring 3 is fixed to the bottom end of the elastic water storage body 2 and covers at most one-third of its circumferential area;

[0031] Extrusion plates 4, multiple extrusion plates 4 are arranged in a ring array inside the cover 1. The radial outer side of each extrusion plate 4 is initially in contact with the inner wall of the cover 1, and a drainage channel is formed between adjacent extrusion plates 4.

[0032] Linking element 5 connects the fixed ring 3 and each extrusion plate 4, converting the axial displacement of the fixed ring 3 into the radial centripetal motion of the extrusion plate 4;

[0033] The elastic water reservoir 2 absorbs water and increases in weight, driving the fixed ring 3 to move axially downward. This, in turn, forces the extrusion plates 4 to contract radially synchronously via the linkage 5, thereby achieving the following:

[0034] The extrusion surface of the extrusion plate 4 gradually compresses the saturated area of ​​the elastic water reservoir 2, forcing the condensate to drain out;

[0035] The drainage channel gradually narrows as the extrusion plate 4 moves centripetally, creating a pulse-like drainage effect.

[0036] Condensate adsorption stage:

[0037] The elastic water reservoir 2 is enclosed outside the oxygen cylinder. The elastic water reservoir 2 adopts a pore distribution with a looser interior and a denser exterior (the porosity is lower near the inner wall of the casing 1 and higher in the central area), forming a capillary adsorption gradient from the inside to the outside. This allows the looser interior area to preferentially adsorb condensate, and the water is transferred to the denser exterior area through capillary action, avoiding localized liquid accumulation and improving the uniformity of water absorption.

[0038] Triggering phase:

[0039] When the adsorbed condensate reaches a certain amount, the elastic water reservoir 2 sinks due to the increased weight. Since the fixed ring 3 only covers at most one-third of the circumferential area of ​​the bottom of the elastic water reservoir 2, an eccentric counterweight effect is formed, ensuring stable triggering of the downward movement. Through the transmission of the linkage 5, which consists of a longitudinal plate 51, a movable plate 52, and a transverse plate 53, the longitudinal plate 51 is fixed to the bottom of the fixed ring 3, the transverse plate 53 is fixed to the radial outer side of the extrusion plate 4, and the two ends of the movable plate 52 are respectively hinged to the longitudinal plate 51 and the transverse plate 53. When the fixed ring 3 moves axially, the movable plate 52 moves to push the transverse plate 53 to generate a thrust on the extrusion plate 4, converting the axial displacement of the fixed ring 3 into the radial centripetal movement of the extrusion plate 4 through the linkage 5.

[0040] Pulse-type drainage stage:

[0041] When the extrusion plate 4 moves centripetally, its extrusion surface preferentially compresses the outer ring of the elastic water reservoir 2, which has low porosity and is saturated, forcing the condensate to flow towards the drainage channel. The progressive compression ratio ensures that water is efficiently squeezed out, rather than just compressing the non-absorbed areas.

[0042] In the initial state, a relatively wide drainage channel is formed between the four adjacent extrusion plates, which facilitates the rapid flow of condensate.

[0043] During the squeezing process, the cross-sectional area of ​​the drainage channel decreases nonlinearly, forming a pulse drainage effect that is fast at first and then slow.

[0044] During the initial rapid drainage, the channel is relatively wide, and a large amount of condensate is quickly discharged under the squeezing action;

[0045] During the later stage of slow flow and splash prevention, the channel gradually narrows to avoid droplet splashing and to restore the elastic water storage body 2, while ensuring that residual water is completely squeezed out.

[0046] Self-recovery phase:

[0047] After the elastic water reservoir 2 loses water, its weight decreases. The spring that elastically suspends the elastic water reservoir 2 at the top rebounds under its own elasticity, causing the fixing ring 3 to move upward and reset. The linkage 5 simultaneously releases the radial constraint on the extrusion plate 4, so that the extrusion plate 4 is reset to its initial state.

[0048] The contact area between the extrusion surface of the extrusion plate 4 and the elastic water reservoir 2 exhibits a progressive compression relationship.

[0049] In the initial state, the extrusion plate 4 is spaced apart from the outer surface of the elastic water storage body 2 to form a pre-compression gap, the width of which is 10%-20% of the free thickness of the elastic water storage body 2.

[0050] During the drainage process, the radial displacement Δr of the extrusion plate 4 and the compression Δh of the elastic water storage body 2 satisfy Δh / Δr≥1.5, which causes the condensate in the saturated area to be directionally squeezed into the drainage channel, ensuring that the water in the saturated area is squeezed out first and avoiding ineffective compression of the non-absorbed area.

[0051] The extrusion surface of the extrusion plate 4 is provided with corrugated guide grooves, the groove depth of which decreases along the drainage direction, and the groove spacing L and the compression amount Δh of the elastic water storage body 2 satisfy L≤0.3Δh, which is used to generate eddy current disturbance during the pulse drainage stage to enhance drainage efficiency.

[0052] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
