Abstract
The utility model relates to a device mainly for a buffer effect for waste gas discharge of an anesthetic machine. The utility model aims to provide a buffer device for waste gas discharge of the anesthetic machine so as to solve a problem of the connection between a waste gas outlet and a negative pressure pipe of the anesthetic machine. The aim of the utility model is realized by the following measures: the buffer device for waste gas discharge of the anesthetic machine comprises an enclosed container and two ports which enable the container to be communicated with the outside environment; the two ports are respectively used for connecting a waste gas outlet and a negative pressure pipe of the anesthetic machine. The characteristics of the above scheme are that between the waste gas outlet and the negative pressure pipe of the anesthetic machine, the container has certain space so that waste gas discharged from the anesthetic machine can be buffered in the space, thereby reducing the influence of negative pressure in the negative pressure pipe upon the anesthetic machine.
Description
Technical field
This utility model relates to a kind of device that mainly plays cushioning effect when being used for the anesthetic machine toxic emission.
Background technology
In hospital, when anaesthetizing surgical patient, operating room all uses inhalation anesthesia medicine (laughing gas, isoflurane, enflurane etc.) in a large number at present.Therefore anesthetic machine can be discharged a large amount of waste gas of anesthesia, and the air in the operating room is polluted.If the medical worker works for a long time, can be subjected in various degree influence to health so under such environment.In order to solve the operating room pollution problem, utilize underbalance effect that waste gas of anesthesia is discharged out operating-room, the waste gas that needs to use the negative pressure pipe that the anesthetic machine outlet port is discharged siphons away, but can not there be big negative pressure in the anesthetic machine outlet port, because big negative pressure can cause the damage of anesthetic machine, so anesthetic machine outlet port and negative pressure pipe are can not be direct-connected.
Summary of the invention
This utility model is intended to provide a kind of waste gas of anesthesia discharging buffer unit, with the connectivity problem of anesthetic machine outlet port and negative pressure pipe in the solution prior art.
The purpose of this utility model can reach by following measure: comprise the container of a sealing, also be provided with two ports that described container is in communication with the outside, described port is respectively applied for and connects anesthetic machine outlet port and negative pressure pipe.
The characteristics of technique scheme are: be connected between anesthetic machine outlet port and the negative pressure pipe at this device, there is certain space in described container, and the waste gas that anesthetic machine is discharged can cushion at this, reduces the influence that the negative pressure in the negative pressure pipe is brought to anesthetic machine.
Further: described port is made of siphunculus, and described siphunculus mouthful is no more than five centimetres apart from container bottom internal tank, described siphunculus at the mouth of external container above container top.Such structure is the preferred version that the inventor thinks, gas is better convection current in container, can guarantee that waste gas of anesthesia is fully diluted by air in container.
Further: described container has been provided with the relief hole of unidirectional air pressure valve effect.When the negative pressure of internal tank was excessive, described relief hole was opened automatically and is sucked extraneous air with the air pressure in the equalizing reservoir, guaranteed that anesthetic machine is not subjected to the influence of excessive negative pressure, was to keep the container internal gas pressure reliably to guarantee stably.
Further: described vessel volume is not less than one liter.Because the common anesthetic machine waste gas velocity of discharge is about about 2L/min, the capacity of at least one liter can satisfy the most of anesthetic machine needs of output substantially.
Further: the distance of described relief hole and described container bottom is not less than ten centimetres.Because described port is near container bottom, described relief hole should be avoided port, avoids the possibility of the gas leak in the container as far as possible.
Further: described container is provided with and is used for fixing the hook that the position is used.So that medical personnel's described container of fixed placement in use.
Description of drawings
Below in conjunction with the drawings and specific embodiments this utility model is described in further detail:
Fig. 1 is the perspective diagram of this utility model embodiment.
The specific embodiment
Known concrete structure and characteristic are no longer set forth at this in the following proposal.As shown in Figure 1: it is filter vat 1 that PVC makes a closed container, ten centimetres of its diameters, and 17 centimetres of Senior Three, 0. 5 centimetres of wall thickness, internal capacity are 11 liter.Filter vat 1 upper base fastens two vertical PVC siphunculus 2, and the diameter of siphunculus 2 is 25 centimetres, and the end opening of siphunculus 2 is apart from go to the bottom three centimetres of filter vat 1.Respectively have long six centimetres, wide 15 a centimetre relief hole 3 about on the bucket wall of filter vat 1, be coated with the spoiler of band reed on 3 mouthfuls of the relief holes, described at ordinary times spoiler blocks relief hole 3 and stops gas communication, when filter vat 1 internal gas pressure during less than an atmospheric pressure, described spoiler externally bends under the atmospheric pressure effect, and extraneous air is flowed into, and guarantees that the air pressure of filter vat 1 can not continue to reduce, spoiler resets under described reed effect behind the air pressure balance, prevents gas communication.20 centimetres of the drum head of the bottom margin filter vat 1 of relief hole 3 also are stained with intrinsic one hook that is used for fixing 4 at the upper base edge of filter vat 1.During use two siphunculus are connected the anesthetic machine outlet port respectively and the negative pressure pipe gets final product.
Only preferred implementation of the present utility model before the above; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from this utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not influence effect and practical applicability that this utility model is implemented.
