Technical Field
The utility model relates to a disposable peripheral venous pressure tester belongs to medical instrument technical field.
Background
At present, a device for measuring peripheral venous pressure clinically mainly comprises a stainless steel needle and 2 glass catheters; need medical personnel manually to connect 3 people in proper order during the use, after injecting aseptic normal saline into glass puts the pipe, prick the needle into upper limbs periphery vein fast, read the scale on the glass puts the pipe afterwards, obtain periphery vein pressure value. Such devices have a number of limitations: 1. the device is fragile and is not easy to store due to the glass product; 2. the repeated use is easy to pollute; 3. the adoption of a multi-section connecting device is easy to slip, and the device is heavy and difficult to operate; 4. the influence of the easy flowing of the normal saline after injection is measured. Therefore, there is a need in the art for a disposable device that is disposable, low cost, easy to use, and convenient for detecting peripheral venous pressure.
Disclosure of Invention
The utility model aims at solving the technical problem of how to conveniently and quickly detect the peripheral vascular venous pressure.
In order to solve the above problems, the technical solution adopted by the present invention is to provide a disposable peripheral venous pressure measuring device; comprises an L-shaped plastic hollow tube, a needle head, a cover and a switch; one end of the L-shaped plastic hollow pipe is provided with a needle head, and the other end is provided with a cover; the middle part of the L-shaped plastic hollow pipe is provided with a switch which is communicated with or closes the two sides of the pipe cavity of the L-shaped plastic hollow pipe.
Preferably, the L-shaped plastic hollow pipe is provided with a corner, and the angle of the corner is 90 degrees.
Preferably, the pipe wall of the L-shaped plastic hollow pipe is provided with scales.
Preferably, a switch is arranged on one side of the corner of the L-shaped plastic hollow pipe, which is far away from the needle head.
Preferably, the switch is provided as a rotary knob switch.
Preferably, the switch is a plug-in type opening/closing switch.
Compared with the prior art, the utility model discloses following beneficial effect has:
ascites is a common disease in the digestive department, and the differential diagnosis of the ascites is very important. The determination of the peripheral venous pressure is crucial to the identification of ascites; meanwhile, the measurement of the venous pressure is also helpful for diagnosis and treatment of heart diseases. The utility model provides a simple and easy apparatus for measuring has simplified the survey step, and easy operation is convenient, and data is more reliable easily acquireing, alleviates patient's misery. The measuring device is light and handy, easy operation, and patient's misery reduces, and contaminated possibility in the operation process reduces.

Detailed Description
In order to make the present invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings:
as shown in figures 1-3, the technical proposal adopted by the utility model is to provide a disposable peripheral venous pressure tester; comprises an L-shaped plastic hollow tube 1, a needle 2, a cover 3 and a switch 4; one end of the L-shaped plastic hollow pipe 1 is provided with a needle head 2, and the other end is provided with a cover 3; the middle part of the L-shaped plastic hollow pipe 1 is provided with a switch 4 which is communicated with or closes the two sides of the pipe cavity of the L-shaped plastic hollow pipe 1. The L-shaped plastic hollow pipe 1 is provided with a corner, and the angle of the corner is 90 degrees. The pipe wall of the L-shaped plastic hollow pipe 1 is provided with scales. A switch 4 is arranged on one side of the corner of the L-shaped plastic hollow pipe 1 far away from the needle head 2. The switch 4 is a rotary knob switch; or a plug-in switch.
The utility model consists of an aseptic plastic hollow pipe 1 with scales, the front part of the plastic hollow pipe 1 is bent by 90 degrees and is provided with a metal steel needle (used for peripheral venipuncture), the joint of the steel needle and the plastic pipe is connected with a plastic knob (similar to a three-way switch), and the sterilized normal saline in the plastic pipe can flow into a needle tube after being opened; the top end of the plastic tube is provided with an opening which can be connected with a sterile syringe to inject sterilized normal saline.
Before clinical use, a nurse selects a proper peripheral pressure measuring vein for aseptic disinfection, carries out aseptic gloves on the sterile pressure measuring vein, then opens an outer envelope of the disposable pressure measuring instrument, takes out the disposable pressure measuring instrument, checks the tightness of the instrument and checks whether a knob at the joint of a needle tube and a plastic pressure measuring tube is normal or not; then, the knob is closed, and sterilized normal saline is injected through the top end opening; after the nurse successfully inserts the instrument front end needle tubing in the peripheral vein, open junction knob, treat that the fluctuation of physiological salt horizontal plane is stable after, read the pressure value and record, take out disposable piezometer pipe after the survey finishes and arrange in the edge tool box and retrieve, disinfect the patient acupuncture department once more.
The utility model discloses a working process:
as shown in figures 1-3, the instrument of the present invention is portable, easy to operate and convenient for clinical application. The instrument mainly comprises a disposable peripheral pressure measuring tube in a disposable closed sealing film, wherein the measuring tube is bent by 90 degrees, a disposable stainless steel needle tube is connected to the lower part of the measuring tube, a disposable plastic tube is sleeved on the needle tube before use, a through knob is arranged above the bending tube and is in a closed state, the measuring tube is opened after being rotated by 90 degrees, liquid can flow down from the upper part, and the liquid cannot flow out after being closed. A sterile plastic tube with 50cm length and scale marks is arranged above the connecting tube, the diameter in the plastic tube is about 0.5cm, and an opening at the top end can be connected with a sterile injection syringe to inject sterilized normal saline; during the use, the patency of the instrument is detected earlier, and after the lower extreme acupuncture periphery vein succeeded, through the top injection sterilization normal saline, open lower extreme junction valve, wait afterwards to read the pressure value after the water column is stable, later close the valve once more, extract the piezometer pipe from the periphery vein, disinfect the acupuncture mouth again.
