Abstract
The utility model relates to a tracheotomy tube air sac pressure monitoring device which belongs to a medical instrument. The utility model has the technical scheme that the tracheotomy tube air sac pressure monitoring device is provided with a support seat, and a water storage box, a scale plate and a pressure-measuring tube are arranged on a frame board of the support seat. One end of the pressure-measuring tube is communicated with the water storage box, and one end of a three-way tube for medical use is communicated with the water storage box through a connection tube. The inflation pressure and capacity of an air sac can be accurately measured by the utility model, and the rapidly quantitative work is realized. The medical quality is enhanced, and disposal therapy procedures are simplified. The safety of patients can be effectively ensured. Because of simple structure of the utility model, the operation is convenient and the cost is low. The utility model is suitable for hospitals of all levels.
Description
Technical field
This utility model relates to a kind of tracheostomy cannula aerocyst pressure monitoring device, belongs to medical apparatus.
Background technology
Existing tracheostomy cannula is made up of conduit, the air bag, the air injection pipe that are contained in conduit outside, when using respirator, conduit is placed in the trachea that patient is cut open, the pipeline of respirator is communicated with the conduit upper port, air bag is clipped between conduit and the tracheal wall, inflates in air bag, and air bag is opened, air bag seals, and can prevent respiratory tract gas leakage and prevent that the anti-thing mistake that flows of digestive tract is drawn to respiratory tract.The metering device that is used for inflation in the air bag at present costs an arm and a leg, be not used widely, because the aeration quantity in the air bag varies with each individual, rely on operator's sensation and experience to grasp aeration quantity in the work, when aeration quantity is not enough, do not reach the effect of sealing, the too much pressure of aeration quantity is greater than 250 millimeter of water (mmH
2O) time, air bag will be oppressed the tracheal wall blood capillary, cause corresponding tracheal wall ischemic necrosis easily, further cause complication such as tracheomalacia, trachealgia leakage, critical patient tracheostomy cannula indwelling time is long simultaneously, and needing repeatedly air bag deflation, charge operation of every day, the pressure of inflation, capacity are difficult to grasp, and therefore control the blowing pressure accurately and rapidly and capacity is of crucial importance.
Summary of the invention
The purpose of this utility model provides a kind of tracheostomy cannula aerocyst pressure monitoring device, and it can accurately monitor the blowing pressure in the air bag, and low price, and is easy to use.
The technical solution of the utility model is: a kind of tracheostomy cannula aerocyst pressure monitoring device, has bearing, it is characterized in that: ater storage box, pressure-measuring pipe, graduated tile are housed on the frame plate of bearing, pressure-measuring pipe is corresponding with graduated tile, the lower end is communicated with ater storage box, and medical tee T one end is communicated with by connection tube and ater storage box are suitable for reading.
During use, the another port of medical tee T is communicated with syringe, and the 3rd port is connected on the air injection pipe of air bag.Because syringe is in the time of the air bag gas injection, gas acts on the liquid level in the water box by connection tube simultaneously, liquid level in the pressure-measuring pipe is risen, this liquid level changes corresponding with the air pressure change in the air bag, the volume change of syringe is corresponding with the capacity of air bag during output gas, the scale of liquid level correspondence is the blowing pressure data record on graduated tile, the milliliter number of syringe output is the data record of air bag capacity, therefore use this monitor can be air bag deflation, inflation provides corresponding data accurately, the operation of realization fast quantification, can simplify and dispose treatment procedure, improve quality of medical care, effectively guarantee patient's safety.Present technique is because simple in structure and make easy to operately, and low cost of manufacture is convenient to popularization and application.
Description of drawings
Accompanying drawing is this utility model tracheostomy cannula aerocyst pressure monitoring device sketch map.
1 end box, 2 ater storage box, 3 frame plates, 4 pressure-measuring pipes, 5 graduated tiles, 6 connection tubes, 7 medical tee Ts, 8 syringes, 9 the 3rd ports, 10 air bags, 11 air injection pipe, 12 conduits, 13 inlet pipes among the figure.
The specific embodiment
The bearing of tracheostomy cannula aerocyst pressure monitoring device is hinged by end box (1) and frame plate (3) and forms, and frame plate when depositing (3) is contained in the end box (1), during work at the bottom of the placement of box (1) level, frame plate (3) is vertical with end box (1).Be equipped with on the frame plate (3) ater storage box (2), pressure-measuring pipe (4) and with pressure-measuring pipe (4) graduated tile (5) side by side, establish inlet pipe (13) in the ater storage box, its mouth of pipe one end places middle part in the box, the other end is fixed on the lid and is communicated with connection tube (6), pressure-measuring pipe (4) upper end open, the lower end is communicated with ater storage box (2), and the water surface of ater storage box (2) is at the 0mmH of pressure-measuring pipe
2On the O graduation mark, the other end of connection tube (6) and syringe (8) link together by medical tee T (7), the 3rd port (9) of medical tee T (7) is communicated with by air injection pipe (11) and air bag (10), air bag (10) invests conduit (12) surface, and air injection pipe (11) one ends are attached on conduit (12) outer wall.The pressure measurement principle of this monitor is identical with sphygomanometer, also sphygomanometer can be converted.Use this monitor at first to determine suitable pressure and the pairing scale of capacity in the tracheostomy cannula air bag, later on according to this calibration data to capable venting of air bag or charge operation.Definite method of convenient pressure value and capability value is to do following operation according to the nursing principle of minimum gas leakage technology of tracheostomy cannula air bag and minimal closure capacity technologies: because of the tracheostomy cannula air bag capacity of placing in the patient's trachea generally is no more than 10ml, so with syringe exhaust 10ml, inject air and make that water column rises to 300mmH in the pressure-measuring pipe to air bag gradually
2O, stethoscope is placed the outer tracheostomy cannula air bag place's auscultation of trachea, after deflate gradually, each 0.5ml finds small leak until auscultation, (uses the respirator person to be as the criterion air-breathing latter stage, autonomous respiration person is as the criterion with EEP), and then inject the 0.5ml air, and this moment, pressure-measuring pipe showed that force value is minimum confining pressure (MOP), syringe shows that the gas flow that has injected is considered as minimum enclosed volume (MOV).This product also can be in the endotracheal tube gasbag pressure of non-tracheotomy, use when capacity is monitored.
