Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a prone position ventilation table. Background Art

[0002] Prone ventilation is breathing or mechanical ventilation in the prone position, which can effectively improve the patient's blood oxygen saturation, and the lung ventilation / blood flow ratio, so that the dorsal collapsed alveoli can be re-expanded, the secretions of the lungs and trachea can be well drained under the action of gravity, and the pressure of the heart and mediastinum on the sagging lung area can be reduced. Prone ventilation is often used for patients with acute respiratory distress syndrome, common / severe pneumonia, refractory hypoxemia that cannot be corrected by conventional mechanical ventilation, and sputum that is difficult to cough up.

[0003] There are several specific positions for prone ventilation. You can lie prone on the bed with your body facing downward and your head facing downward or to one side. You can also still lie prone on the bed, but with your body tilted at a 30-degree angle to the bed, with one side of your body supported by a cushion. For awake patients, you can also use a sitting position instead of the conventional prone position; you can sit next to the bed and lean over it, but since the bed is short, the comfort level is poor; you can also use a table, sit next to it and lean over it, which is more comfortable.

[0004] As far as the applicant knows, there is no dedicated table for prone ventilation. The only option is to use an ordinary table, put a pillow or other flexible pad on the table, and then lie on it. The disadvantage of this method is that the patient who is mechanically ventilated in the prone position wears a ventilator mask, which is connected to a ventilator tube, and the mask and ventilator tube are easy to interfere with the table; the pillow or other flexible pad is placed on the table without being fixed, and the patient is often not asleep, so the head will move, which may cause the flexible pad to shift and fall off the table.

DETAILED DESCRIPTION

[0024] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0025] like Figures 1 to 6As shown, the prone position ventilation table includes a table frame 1 and a table top panel 2; the table frame 1 includes a table frame side panel 11, a table top panel rotation shaft 18 and a positioning knob 12; the number of the table frame side panels 11 is two, the two table frame side panels 11 are spaced apart in the left and right directions, the table top panel rotation shaft 18 is arranged in the left and right directions, and the two ends of the table top panel rotation shaft 18 are respectively connected to the two table frame side panels 11; the table top panel 2 includes a table top panel body 21 and a sealing plate 22, the table top panel body 21 is located between the two table frame side panels 11 and is mounted on the table top panel rotation shaft 18, the table top panel body 21 has a through notch 211, the sealing plate 22 is filled in the through notch 211 and can be removed, and the two sides of the table top panel body 21 and the sealing plate 22 are respectively a soft surface and a hard surface; the positioning knob 12 is connected to a table frame side panel 11, and when either side of the table top panel 2 is facing up, the positioning knob 12 can limit the rotation of the table top panel body 21.

[0026] The utility model provides a through-notch 211 on the table top body 21, and the sealing plate 22 is filled in the through-notch 211 and can be removed. When the sealing plate 22 is removed, when the mechanically ventilated patient lies on the table, the breathing mask can face the through-notch 211, and the ventilator tube can pass through the through-notch 211, thus avoiding interference between the table and the breathing mask and the ventilator tube.

[0027] One side of the table top 2 is a flexible surface, and the other side is a hard surface. When the patient is lying prone for ventilation, the flexible surface faces upward, and the patient can lie directly on the table top 2 without using a flexible pad. When the patient is not lying prone for ventilation, the table top 2 can be turned over so that the hard surface faces upward, and the table for prone ventilation can be used as an ordinary table for dining, etc. When the table for supine ventilation can be used as an ordinary table, the sealing plate 22 is reinstalled so that the table top 2 is the same as the panel of an ordinary table.

[0028] The hard parts of the table frame 1 and the table top 2 are made of existing common table materials, and the flexible part of the table top 2 can be made of materials such as foam and latex, and is wrapped with an easy-to-clean surface layer on the outside.

[0029] The positioning knob 12 limits the rotation of the desktop panel body 21 to fix the desktop panel 2. When the desktop panel 2 needs to rotate, the positioning knob 12 releases the restriction. The specific method of limiting the rotation of the desktop panel body 21 by the positioning knob 12 is preferably as follows: two conical positioning holes 212 are provided at one end of the desktop panel body 21, and the two conical positioning holes 212 are symmetrically arranged on both sides of the desktop panel shaft 18; the positioning knob 12 is arranged in a one-to-one correspondence with the conical positioning holes 212, and the positioning knob 12 has a conical positioning column 121 that matches the conical positioning hole 212, and the conical positioning column 121 is inserted into the conical positioning hole 212 and pressed against the hole wall of the conical positioning hole 212.

[0030] Loosen the positioning knob 12 to allow the tapered positioning column 121 to exit the tapered positioning hole 212, and the positioning knob 12 will release the restriction on the rotation of the desktop 2. The advantage of using the tapered positioning column 121 and the tapered positioning hole 212 is that a gap can be avoided between the positioning knob 12 and the desktop body 21, ensuring that the desktop 2 is fixed firmly.

[0031] The specific method of connecting the sealing plate 22 to the desktop panel body 21 is preferably as follows: the desktop panel body 21 has a slot 213 arranged along the wall of the notch 211; the sealing plate 22 has a sealing plate flange 221 arranged along the edge of the sealing plate 22, and the sealing plate flange 221 is inserted into the slot 213; the desktop panel 2 includes a sealing plate positioning structure 23, which is installed on the desktop panel body 21 and can limit the outward movement of the sealing plate 22.

[0032] The specific structure of the sealing plate positioning structure 23 is preferably as follows: a positioning structure hole 214 and a nut groove 215 are provided on both sides of the desktop panel body 21 through the notch 211; the sealing plate 22 has a conical socket 222 corresponding to the positioning structure hole 214; the sealing plate positioning structure 23 includes a positioning shaft 231 and an adjusting nut 232, the positioning shaft 231 is inserted into the positioning structure hole 214, the positioning structure hole 214 limits the rotation of the positioning shaft 231, the end of the positioning shaft 231 is a positioning shaft conical head 2311, the adjusting nut 232 is located in the nut groove 215, the left and right surfaces of the adjusting nut 232 are respectively fitted with the left and right walls of the nut groove 215, the adjusting nut 232 is threadedly connected to the positioning shaft 231, and the positioning shaft conical head 2311 is inserted into the conical socket 222.

[0033] The sealing plate flange 221 is inserted into the slot 213, so that the sealing plate 22 can only move outward, and the sealing plate positioning structure 23 limits the sealing plate 22 from moving outward, so that the sealing plate 22 is effectively fixed. Since the left and right surfaces of the adjusting nut 232 are respectively in contact with the left and right walls of the nut groove 215, the adjusting nut 232 can only rotate but not move; since the positioning shaft 231 is inserted into the positioning structure hole 214, the positioning structure hole 214 limits the rotation of the positioning shaft 231, and the positioning shaft 231 can only move axially but not rotate. In this way, the adjusting nut 232 and the positioning shaft 231 actually form a screw nut structure. Rotate the adjusting nut 232, and the positioning shaft 231 moves axially. The positioning shaft 231 moves axially until the conical head 2311 of the positioning shaft is inserted into the conical socket 222, which limits the sealing plate 22 from moving outward. The positioning shaft 231 moves axially until the conical head 2311 of the positioning shaft exits the conical socket 222, and the sealing plate 22 can be moved outward and removed. The advantage of using the positioning shaft conical head 2311 and the conical socket 222 is that a gap between the positioning shaft 231 and the sealing plate 22 can be avoided, thereby ensuring that the sealing plate 22 is fixed firmly. The positioning structure hole 214 can limit the rotation of the positioning shaft 231 by making the non-threaded part of the positioning shaft 231 into a square shape, and correspondingly, the part of the positioning structure hole 214 that matches the square part can also be made into a square shape.

[0034] After the sealing plate 22 is removed, there should be a place to put it. For this reason, the utility model preferably has a placement grid 13 on the table frame 1, and the sealing plate 22 can be placed in the placement grid 13 after being removed.

[0035] The prone position ventilation table is not a common item in the ward, and should be easy to move. There are awake patients who need prone ventilation, and they are moved into the ward for use. If there are no such patients, they are moved out of the ward for storage. For easy movement, the bottom of the preferred table frame 1 is provided with a roller 17 with a brake.

[0036] When using the prone position ventilation table, the patient is in a sitting position, so a stool or a chair is also needed. Existing stools can be used. However, in order to make the use of the utility model more convenient, the utility model is preferably a complete set of products, that is, the prone position ventilation table includes a stool 3; the stool 3 is connected to the table frame 1, and the stool 3 can be moved to be located under the table frame 1 or outside the table frame 1.

[0037] Specifically, the table frame 1 includes a stool shaft 15, which is provided with a supporting flange 16; the stool 3 includes a rotating arm 31, a stool panel 32, a stool upright 33, a stool base 34 and a spring 35. One end of the rotating arm 31 is mounted on the stool shaft 15 and rests on the supporting flange 16, and the other end of the rotating arm 31 has a rotating arm hole 311. The stool upright 33 is vertically arranged and passes through the rotating arm hole 311. The stool panel 32 and the stool base 34 are respectively connected to the upper and lower ends of the stool upright 33. The spring 35 is mounted on the stool upright 33 and is located between the stool panel 32 and the rotating arm 31; the spring 35 supports the stool panel 32 so that the bottom surface of the stool base 34 is higher than the lower edge of the roller 17; when a person sits on the stool panel 32, the stool panel 32 is pressed down, and the bottom surface of the stool base 34 is flush with the lower edge of the roller 17.

[0038] Thus, when the utility model is used, Figure 3 As shown, the stool 3 is turned out, and the patient can sit on the stool 3 and lie on the table top 2. When the utility model is not in use, the stool 3 is turned under the table frame 1, and the stool 3 does not occupy space. The stool 3 can move with the table frame 1. Due to the support of the spring 35, the stool base 34 is off the ground, and the stool 3 is easy to rotate. When the patient sits on the stool 3, due to the increase of the patient's weight, the stool panel 32 is pressed down, and the stool base 34 touches the ground. The above effect can be achieved by reasonably setting the spring 35.

[0039] When the bench 3 is rotated under the table frame 1, it should be fixed to prevent the bench 3 from rotating out when the utility model is moved. Specifically, the following method can be adopted: the table frame 1 has a bench panel groove 14, and when the bench 3 is moved to be located under the table frame 1, the bench panel 32 is located in the bench panel groove 14, and the bench panel groove 14 restricts the movement of the bench panel 32.

[0040] In this way, when the stool 3 is rotated in or out from under the table frame 1, the stool base 34 is stepped on to move the stool panel 32 downward by a certain distance, so that the upper surface of the stool panel 32 is lower than the notch of the stool panel groove 14, and the stool 3 can be rotated. When the stool 3 is rotated under the table frame 1, the foot is released, and the spring 35 rebounds to move the stool panel 32 upward and enter the stool panel groove 14. This limiting method of the stool 3 is simple in structure and very convenient to operate.
