Description

Medical Ventilator Humidifier

The present invention relates to a medical respiratory gas humidifier capable of automatically promoting a patient's breathing by delivering inhalation and exhalation through a mask and hose worn on the patient's face, and to a medical respiratory gas humidifier manufactured so that a chamber for controlling the temperature and humidity of fluid supplied to the patient can be easily removed.

In general, a respirator is a device that is absolutely necessary to protect life in disaster areas or in emergency situations in daily life, as it is a means of artificially supplying a mixture of oxygen and air to patients in specialized medical institutions or hospitals to sustain their lives until they recover.

A conventional manual ventilator is a respiratory support device mainly used to provide artificial respiration to patients in emergency situations such as cardiopulmonary resuscitation or acute respiratory failure, or in surgical settings requiring general anesthesia.

The method in which users of manual respirators manually apply pressure to the air bladder to create artificial respiration had the problem of not being able to continuously control a constant amount of breathing because the method of applying pressure varied depending on the user, and physical characteristics such as hand size and grip strength varied, so the amount of air supplied through the air bladder was not constant.

Due to these problems, many automated devices for artificial respirators have been developed, but since research and development has been conducted only for use within medical institutions, only devices that can be used in spaces where normal medical activities can be performed under all conditions have been disclosed.

Recently, the use of ventilators has increased rapidly due to COVID-19, which has led to a shortage of ventilators and even a shortage of medical staff. As a result, countries around the world are trying to develop automatic pumping devices for ventilators, but there is a problem that the design is complex, which increases the cost of production and makes it burdensome to use in the field.

Therefore, there is a need to develop a medical respiratory gas humidifier that can reduce manufacturing costs and be easily used by medical staff and guardians caring for patients.

Referring to the drawings below, one embodiment of a medical respiratory gas humidifier of the present invention will be described in detail.

Referring to Figure 1, the present invention includes a main body (100), a chamber (200), a supply pipe (300), a discharge pipe (400), and a connector part (500).

The main body (100) includes a main body (110) that controls the operation of components installed in the main body (100) and is equipped with a control unit that supplies power. A control switch for driving and a display unit (111) that outputs an operating status are further formed on one side of the main body (110).

A heating plate (112) that receives power and generates heat is further formed on the upper surface of the main body (100). The heating plate (112) is a metal heating plate that can be heated to a predetermined temperature. A chamber (200) can be installed on the upper surface of the heating plate (112).

The chamber (200) includes a body (210) in which a predetermined space is provided so that water can be accommodated therein, and a bottom protrusion (220) that protrudes radially from the lower surface of the body (210). Air is introduced into the interior of the chamber (200), and the introduced air is heated and humidified while being mixed with evaporated water vapor, and then discharged. An inlet pipe (300) and an outlet pipe (400) described below are connected to the chamber (200), and a pair of inserts (230) through which air is introduced/discharged may be further formed. The chamber (200) is mounted on a heating plate (112) and receives thermal energy from the heating plate (112) to heat the interior of the chamber (200).

Referring to FIGS. 1 and 2, the main body (100) further includes a post (150). A mounting portion (151) is formed protrudingly at the lower side of the side of the post (150), and a part of the lower side of one side of the chamber (200) is caught on the mounting portion (151), so that the bottom surface of the chamber (200) can be in close contact with the heating plate (112). In addition, the post (150) is provided with a first electrical connector (152) at one end and extends upward from one side of the upper surface of the main body (100) to a predetermined length, but has a shape in which one end is bent in a horizontal direction.

Referring to FIG. 3, a supply pipe (300) is connected to a separately provided artificial respiration unit on one side to receive air from the artificial respiration unit, and the other side is connected to an insertion part (230) of a chamber (200) to introduce air into the chamber (200). The supply pipe (300) is formed of a flexible material so that it can be freely deformed, and a heating wire (310) is provided inside to prevent moisture from forming on the inner surface of the supply pipe (300).

The discharge pipe (400) has the same shape as the supply pipe (300), and one side is connected to the chamber (200) to receive heated and humidified air from the chamber (200) and deliver it to the breathing mask. The discharge pipe (400) is also equipped with a heating wire (410), and the heating wire (410) receives power from the outside and generates heat, thereby preventing moisture from forming on the inner surface of the discharge pipe (400).

The connector (500) is configured to connect the supply pipe (300) and the discharge pipe (400) to the insertion portion (230) of the chamber (200), respectively, by holding the supply pipe (300) and the discharge pipe (400) and then connecting the supply pipe (300) and the discharge pipe (400) to the insertion portion (230). In addition, the connector (500) includes a second electrical connector (530) that is electrically connected to the first electrical connector (152) when the chamber (200) is mounted on the heating plate (112) of the main body (100). When the first electrical connector (152) and the second electrical connector (530) are connected, power is supplied to the heating wires (310, 410) formed inside the supply pipe (300) or the discharge pipe (400). Therefore, the connector (500) has a structure that is detachable from the post (150).

As an example of the supply pipe (300) and the discharge pipe (400), the heating wire (310, 410) can be connected to the second electrical connector (530) to receive power. (See Fig. 5)

Referring to FIG. 2, the connector (500) further includes a protection tube (540). The protection tubes (540) are configured as a pair so that one end of each of the supply pipe (300) and the discharge pipe (400) is fitted. The protection tubes (540) can prevent the supply pipe (300) and the discharge pipe (400) from being separated from the connector (500) due to external force.

In addition, the protection tube (540) can prevent one end of the supply pipe (300) and the discharge pipe (400) from being easily damaged. That is, the supply pipe (300) and the discharge pipe (400) have a thin thickness, and when flow occurs in the supply pipe (300) and the discharge pipe (400), one end of the supply pipe (300) and the discharge pipe (400) connected to the connector (500) is damaged. At this time, the protection tube (540) can prevent the supply pipe (300) and the discharge pipe (400) from being torn or easily damaged by wrapping one end of the supply pipe (300) and the discharge pipe (400).

Referring to FIG. 2, the connector portion (500) includes a first housing (510) and a second housing (520).

The first housing (510) is extended to a predetermined length, and a fixing groove (511) is formed at a predetermined depth in the center to fix a supply tube (600) that supplies water to the interior of the chamber (200). The supply tube (600) is connected to the chamber (200) and has a thin tube shape that receives water from the outside. When the supply tube (600) is fitted into the fixing groove (511), the supply tube (600) is stably fixed, thereby preventing a part of the supply tube (600) adjacent to the chamber (200) from being bent or constricted.

And, a pair of first fitting grooves (512) are formed in the first housing (510) to surround a portion of each side of the supply pipe (300) and the discharge pipe (400). Each of the first fitting grooves (512) can be spaced apart by the same interval as the interval between the inlet (220) and the discharge pipe (230). A portion of the side of the supply pipe (300) and the discharge pipe (400) is inserted into the first fitting grooves (512).

The second housing (520) is symmetrically connected to the first housing (510). The second housing (520) is formed with a second fitting groove (522) facing the first fitting groove (512). Part of the other side of each of the supply pipe (300) and the discharge pipe (400) is inserted into the second fitting groove (522).

Therefore, when the first and second housings (510, 520) are coupled to each other, the supply pipe (300) and the discharge pipe (400) can be fixed to the connector (500).

Referring to FIG. 2 and FIG. 7, a support rod (550) is further formed in the second housing (520). The support rod (550) is formed to extend to a predetermined length on the rear surface of the second housing (520) facing the post (150).

Referring to Fig. 7, a load-receiving groove (154) is further formed on the post (150) in which a portion of the end of the support rod (550) is received. The load-receiving groove (154) is formed by being recessed into the lower surface of the post (150) to a predetermined depth.

In addition, a water level indicator auxiliary part (153) is further provided on one side of the post (150) to visually check the water level inside the chamber (200) from the outside. The water level indicator auxiliary part (153) is equipped with an LED module, and the LED emits light to irradiate a predetermined light to the chamber (200). The irradiated light is reflected by the water contained inside the chamber (200) as it passes through the chamber (200), so that the water level of the water contained in the chamber (200) can be checked.

Referring to (a) of Fig. 7, the chamber (200) enters the main body (100) while being tilted at a predetermined angle. At this time, the tip of the support rod (550) is guided and inserted while first entering the rod fixing groove (154).

At the same time, the first electrical connector (152) and the second electrical connector (530) are partially connected. Afterwards, when the tilted chamber (200) is adjusted to maintain a horizontal position, the support rod (550) is supported by the rod fixing groove (154) and pushes the second electrical connector (530) upward. As a result, the second electrical connector (530) is more closely attached to the first electrical connector (152), thereby preventing poor contact. (See Fig. 7 (b))

Referring to FIG. 4, a fixing rib (541) may be further provided on the side of the protection tube (540) to guide the position of the protection tube (540) fixed to the connector (500) by inserting the first and second fitting grooves (512, 522). The fixing ribs (541) are provided on the upper and lower sides of the first and second fitting grooves (512, 522), respectively, and the protection tube (540) is fixed to the connector (500) when the first and second fitting grooves (512, 522) are inserted between the spaced-apart fixing ribs (541).

Referring to Fig. 2, the first electrical connector (152) is formed to have a shape that is open horizontally and downwardly, and the second electrical connector (530) is formed to have a shape that is open horizontally and upwardly. As a result, the first electrical connector (152) and the second electrical connector (530) can be connected as the connector (500) moves upwardly.

Referring to FIG. 6, as an example of a connection of the first and second electrical connectors (152, 530), the first and second electrical connectors (152, 530) are formed so that they are open in both the horizontal direction and the vertical direction, and the first electrical connector (152) is exposed at one end of the post (150), and the second electrical connector (530) is exposed at the rear of the connector (500). Accordingly, the entry direction of the connector (500) through which the first and second electrical connectors (152, 530) can be interconnected can be any direction, including the upper, lower, and side directions. Accordingly, the connector (500) can be fixed to the post (150) in various directions.

Referring to FIG. 2 and FIG. 6, guide wings (560) may be further formed on the rear surface of the connector (500) facing the post (150) to guide the connection positions of the first and second electrical connectors (152, 530). The guide wings (560) are configured as a pair spaced apart at a predetermined interval, and may be spaced apart at an interval corresponding to the width length of one end of the post (150).

Referring to FIG. 1 and FIG. 8, a fixing member (114) for fixing a chamber (200) mounted on a main body (100) is further formed on one side of the main body (110) facing the post (150). When the chamber (200) enters the main body (100) while being tilted at a predetermined angle, the protrusion (220) of the chamber (200) is first supported on the mounting member (151). Thereafter, the tilted chamber (200) is settled on the heating plate (112) to maintain a horizontal level, and at the same time, the protrusion (220) of the chamber (200) facing the fixing member (114) is fitted into the fixing member (114), so that the fixing member (114) can fix the chamber (200).

The fixed part (114) is inserted into the installation groove (110-1) formed in the main body (110) and can be detached from the protrusion (220) of the chamber (200) by sliding forward and backward.

When the protrusion (220) presses the upper surface of one side of the fixed part (114), an inclined part (114-1) having a predetermined angle of inclination may be further provided on the upper surface of one side of the fixed part (114) so that the fixed part (114) slides forward.

Meanwhile, an elastic member (113) for elastically supporting the heating plate (112) may be further provided at the bottom of the heating plate (112). The heating plate (112) has a predetermined amount of clearance in the vertical direction due to the elastic member (113). As a result, the chamber (200) mounted on the heating plate (112) is pressed with a predetermined amount of elasticity, thereby improving the adhesion between the bottom surface of the chamber (200) and the heating plate (112), and at the same time, preventing movement of the chamber (200) due to vibration transmitted to the chamber (200) after being fixed to the fixing member (114).

Referring to Fig. 9, the fixed part (114) is installed to slide forward and backward in the installation groove (110-1) and includes a body (114a) that selectively presses the protrusion (220) on one side and a grip part (114b) formed on the other side of the body (114a) to move the body (114a). In addition, a catch (114c) is further formed at the lower end of one side of the body (114a) to prevent the body (114a) from being separated from the installation groove (110-1) when the body (114a) is slid forward.

On both sides of the body (114a), guide protrusions (114d) for horizontal movement of the body (114a) are further formed, and a guide groove (110-2) can be formed by inserting a guide protrusion (114d) into the installation groove (110-1) to guide the movement direction of the body (114a).

In addition, the catch (114c) is formed with an insertion groove (114e) into which a protrusion (220) is inserted when the fixed portion (114a) slides toward the chamber (200). When the protrusion (220) is inserted into the insertion groove (114e), the chamber (200) can be prevented from being separated from the main body (110) by the elasticity of the heating plate (112). In addition, an elastic member (114f) is further provided between the catch (114c) and the inner surface of the main body (110) to elastically support the body (510).

Referring to FIG. 10, as an example of a heating plate (112), an elevating member (112-1) that rotates at a predetermined angle and descends may be further provided on one side of the heating plate (112) adjacent to the post (150).

The lift member (112-1) rotates at a predetermined angle and descends to provide a space in which the chamber (200) can be inserted when the chamber (200) tilts and enters the main body (110). A coil spring that elastically supports the lift member (112-1) may be further provided at the portion where the heating plate (112) and the lift member (112-1) are connected, and although not shown in the drawing, a coil spring may be further provided on the lower surface of the lift member (112-1).

The present invention with this configuration has the advantage of providing convenience of use in medical settings by allowing easy attachment/detachment of the connector portion (500) and the main body (100).
