Medical gas supply system terminal device

Technical field

The utility model relates to medical air supply systems, in particular to medical gas supply system terminal device.

Background technique

Medical gas supply system, also known as life-support system, for maintaining the life of urgent patient, promoting patient's health Again, drive various medical treatment apparatus etc.；The medical gas supply system terminal device that Hospitals at Present uses is substantially the same, including pedestal And air inlet pipe, realize that gas supply, Chinese patent CN2571406Y disclose medical gas supply system terminal dress by air inlet pipe air inlet Set, which is mainly made of socket and the connector being connected with steam line, and socket is fixedly connected with connector, socket with connect Design has two seals on the gas passage that head is constituted, and design has the gear for making two seals open-shut linkage between two seals Structure, design has the circular cone pilot hole for connection gas appliance plug on the gas passage in socket, designs on socket There is retaining mechanism plug being fixed in pilot hole, which is inserted into gas appliance plug and is taken out fast It is convenient, flexible, but the device realizes the open-shut linkage of two seals by sphere core and holddown spring, only works as sphere core The Shi Caineng on " O " type sealing ring that is pressed on tightly plays the role of preventing gas leakage, when sphere core can not be with " O " type sealing ring It fits closely, it will cause gas to leak, and the apparatus structure is complicated, the case where gas leakage is not easy to be found in time, makes At the waste of bulk gas.

Utility model content

It is not easy the problems such as finding in order to solve gas leakage in the prior art, the utility model provides medical gas supply system Terminal installation, the medical gas supply system terminal apparatus structure is simple, can find in time when leakage occurs in gas, and then timely Replacement, avoids largely wasting gas.The utility model specific technical solution is as follows:

The utility model provides medical gas supply system terminal device, which includes that top is opened The airway from top to bottom gradually collapsed that mouth, bottom end are equipped with the connector of through-hole and connect across through-hole with connector, ventilation are led Pipe is the structure of end sealing, bottom end opening, and one end that airway stretches out connector is connected with air supply pipe, and airway protrudes into One end of connector is from top to bottom arranged with seal pipe and spring respectively, and the top of spring is in contact with the bottom end of seal pipe, sealing The inner sidewall of pipe is fixedly connected with elastic sealing gasket, and airway side wall corresponding with elastic sealing gasket is equipped with venthole, Airway is greater than the internal diameter of seal pipe far from the diameter of air supply pipe one end, less than the outer diameter of seal pipe, under venthole and connector The distance between wall upper surface is greater than the sum of the length when length and spring-compressed of seal pipe.

Preferably, connector is made of transparent material.

Preferably, when spring-relaxation, the bottom connection of venthole and elastic sealing gasket is touched.

Preferably, the upper surface of seal pipe is equipped with gasket.

Wherein, the outer diameter of seal pipe is less than with the outer diameter of gas utensil, greater than the outer diameter of airway；The utility model structure Simply, it can be realized gas supply through the above arrangement, due to having a distance between venthole and the top of elastic sealing gasket, because This, even if the flexibility decrease of spring, as long as when spring-relaxation, the upper surface of elastic sealing gasket is higher than the upper surface of venthole Realize sealing, without gas leak phenomenon, if spring it is very poor leak air phenomenon when, user is in connection gas device Tool is exposed to except elastic sealing gasket with discovery venthole is also easy when connector, therefore can timely be taken measures, and gas is avoided Body is largely revealed.

Further to improve, medical gas supply system terminal device further includes for jointing and with the connection of gas utensil Part, connector include annular plate and the flexible fastening piece that is fixedly connected with the inner sidewall of annular plate, the circumferential side wall of annular plate Equipped with fastener, the inner sidewall of the one end of connector far from air supply pipe is equipped with the card slot cooperated with fastener, and card slot includes interconnected First card slot, the second card slot and third card slot, the first card slot and third card slot are each perpendicular to the second card slot and are located at the second card slot The same side, the one end of the first card slot far from the second card slot is connected with the top of connector, on flexible fastening piece and airway Lower correspondence.

The utility model avoids maloperation with the above arrangement, the connection using gas utensil and connector is more convenient, secured It is detached from using gas utensil and connector.

Further to improve, the first card slot is communicated with several the second card slots, and each second card slot is communicated with one the Three card slots, the side wall that airway is in contact with elastic sealing gasket are from top to bottom equipped with multiple ventholes, between adjacent vent holes Distance it is equal with the distance between adjacent second card slot, the distance between each venthole and connector lower wall upper surface are big The sum of length when the length and spring-compressed of seal pipe.

The utility model can be realized the purpose for adjusting gas supply flow, without being once again set up by the way that multiple ventholes are arranged Flow control valve, in use, need to make fastener mutually to fix with corresponding third card slot according to gas supply flow, simple and convenient, It is easily operated, low in cost.

It is further to improve, air supply pipe include the first air supply pipe being connected with airway and with the first air supply pipe bottom end The second air supply pipe and third air supply pipe being connected, the second air supply pipe and third air supply pipe are connected with air feed tank, and second supplies Tracheae and third air supply pipe are equipped with switch valve close to one end of the first air supply pipe.

By the first air supply pipe of setting, the second air supply pipe and third air supply pipe, when use, can first open the utility model One air supply pipe, an air supply pipe in the event of failure, by turning off the air supply pipe upper switch valve of failure, opens non-failure wherein Switch valve on air supply pipe saves the step of patient replaces entire supplying terminal, easy to operate, quick.

The beneficial effects of the utility model are as follows: medical gas supply system terminal apparatus structure letter provided by the utility model It is single, it can be realized gas supply, even if the flexibility decrease of spring, as long as when spring-relaxation, the upper surface of elastic sealing gasket is higher than ventilation Sealing can be realized in the upper surface in hole, when without gas leak phenomenon, when spring is very poor leak air phenomenon when, use Person is also readily seen that venthole is exposed to except elastic sealing gasket in connection gas utensil and connector, therefore can timely adopt Measure is taken, gas is avoided largely to reveal.
