Description
Technical field
The utility model relates to anesthesia respiration loop pipe manufacturer's device that (leakage or stifled) checked to its impermeability when factory inspection.
Background technology
When patient when undergoing surgery, often to anaesthetize, and when anaesthetizing the requisite anesthesia respiration loop pipe of using.The gas delivery port of Anesthesia machine is formed a loop mutually with the patient respiration road, be called the anesthesia respiration loop.By the anesthesia respiration loop live gas and inhalation anesthetic are transported in patient's the respiratory tract, and arrive patient expired air scavenge external.
The anesthesia respiration loop pipe must check the impermeability of breathing circuit pipe when the factory inspection of medicine equipment manufacturer, patient anaesthetized efficiently when the operation guaranteeing.The leakage that the breathing circuit pipeline is small everywhere can cause the minimizing anaesthetic effect to influence the doctor patient in the operation is made judgement accurately.Each plastic injection-moulded assembly stops up because of the gas circuit that the injection moulding reason causes, and the breathing circuit that can influence patient is not smooth, causes expiratory dyspnea, and then influences carrying out smoothly of operation.
The utility model content
The purpose of this utility model just provides a kind of anesthesia respiration loop pipe airtight test device, when it can effectively check the small leakage of breathing circuit pipe everywhere, effectively detects the breathing gas circuit that causes because of injection moulding reason or assembly failure and stops up.
To achieve these goals, the technical scheme that the utility model adopted is:
A kind of anesthesia respiration loop pipe airtight test device, comprise little differential pressure indicator one, little differential pressure indicator two, standard anesthesia respiration loop pipe, the gases at high pressure reservoir bottle, the positive end interface of little differential pressure indicator one is communicated with the air inlet pipeline sealing of standard anesthesia respiration loop pipe by pipeline, the positive end interface of little differential pressure indicator two is communicated with the outlet pipe sealing of standard anesthesia respiration loop pipe by pipeline, the output terminal of gases at high pressure reservoir bottle is connected with bronchus one, bronchus two, gas filling valve one is installed on the bronchus one, gas filling valve two is installed on the bronchus two, and the end of bronchus one is communicated with the taper joint sealing of standard anesthesia respiration loop pipe.
Further preferred as such scheme, described gas filling valve one, gas filling valve two all select for use zero-pressure to start solenoid valve.Zero-pressure starts solenoid valve can be adjusted to gases at high pressure the low-pressure gas of 10-30Kpa, and can or close according to instruction unpack, the anesthetic gases pressure that adopts when effectively the simulated respiration machine is anaesthetized.
The utility model is simple in structure, adopts two little differential pressure indicators, and air inlet pipeline and the outlet pipe to the anesthesia respiration loop pipe detects respectively, can detect leakage that air inlet pipeline or outlet pipe produce or stifled easily.Pipe to be measured is connected with this device by the self-control modular connection, can detect the leakage of pipe pipe to be measured or block up in 6-8s, makes things convenient for manufacturing enterprise to carry out the large batch of detection of dispatching from the factory.
In a word, the beneficial effects of the utility model are: little differential pressure indicator that this device adopted, can detect the small pressure reduction of 0-500pa, guarantee under the gastight situation through the bowssening check in standard anesthesia respiration loop pipe, the leakage that the arbitrary pipeline of pipe to be measured produces or stifledly all can between pipe to be measured and standard pipe, produce small pressure reduction, thereby alarm indication helps the operating personnel to judge accurately and rapidly.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model anesthesia respiration loop pipe airtight test device comprises little differential pressure indicator 1, little differential pressure indicator 22, standard anesthesia respiration loop pipe 3, gases at high pressure reservoir bottle 4.The positive end interface of little differential pressure indicator 1 is communicated with air inlet pipeline 31 sealings of standard anesthesia respiration loop pipe 3 by pipeline, and the positive end interface of little differential pressure indicator 22 is communicated with outlet pipe 32 sealings of standard anesthesia respiration loop pipe 3 by pipeline.The output terminal of gases at high pressure reservoir bottle 4 is connected with bronchus 1, bronchus 26, gas filling valve 1 is installed on the bronchus 1, gas filling valve 2 61 is installed on the bronchus 26, and the end of bronchus 1 is communicated with taper joint 33 sealings of standard anesthesia respiration loop pipe 3.Wherein, gas filling valve 1, gas filling valve 2 61 all select for use zero-pressure to start solenoid valve.
When the utility model anesthesia respiration loop pipe airtight test device uses, the negative terminal interface of little differential pressure indicator 1 is communicated with air inlet pipeline 71 sealings of pipe 7 to be measured by pipeline, the negative terminal interface of little differential pressure indicator 22 is communicated with outlet pipe 72 sealings of pipe 7 to be measured by pipeline, and the end of bronchus 26 is communicated with taper joint 73 sealings of pipe 7 to be measured.
Concrete principle of work is as follows:
Zero-pressure starts solenoid valve according to instruction, simultaneously standard anesthesia respiration loop pipe 3 and pipe to be measured 7 is inflated, and general inflationtime is 1-2s, and after inflation finished, zero-pressure started closed electromagnetic valve.When the air inlet pipeline 71 of pipe 7 to be measured or outlet pipe 72 produce small leakage or stop up, will produce small pressure reduction at standard anesthesia respiration loop pipe 3 and pipe to be measured 7 two ends.Surpass the alarm range of little differential pressure indicator 1 or 22 settings of little differential pressure indicator when pressure reduction after, little differential pressure indicator 1 or the corresponding electric signal of little differential pressure indicator 22 outputs, the gas leakage or the obstruction of prompting operation workman's pipe 7 to be measured.Generally speaking, inflationtime is 1-2s, and relatively the time is 2-4s, and the whole process of finishing pipe 7 detections to be measured only needs 6-8s.
Detection validation: stab a little eye with the 7# pin on pipe 7 to be measured, this device can detect the leakage of respective line in 2s.Stab an eye with the 9# pin on pipe 7 to be measured, device can detect the leakage of respective line in 3s, tries to stop up on pipe 7 to be measured with gauze, and device can detect the obstruction of respective line in 1s.
Need to prove at this, be connected the modular connection of all adopting national standard between each pipeline and standard anesthesia respiration loop pipe 3, the various pipe 7 to be measured.The utility model can detect various types of breathing circuits (children's, adult etc.) easily.
This anesthesia respiration loop pipe airtight test device, practical simple, quick, safety, each modular connection can be connected with various breathing circuits easily, has guaranteed effect of one machine multiple purposes, detected pressures simulated respiration pressure that machine provides, the impermeability of the product that effectively guaranteed to dispatch from the factory.
The foregoing description only is used to the inventive concept of the present utility model of explaining, but not to the qualification of the utility model rights protection, allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should fall into protection domain of the present utility model.
