CN205145278U - Closed venous transfusion pressure equaliser in hyperbaric oxygen cabin - Google Patents

Abstract

The utility model discloses a closed venous transfusion pressure equaliser in hyperbaric oxygen cabin, including the plastics infusion bottle, with the transfusion system of plastics infusion bottle intercommunication, its characterized in that still includes: a follow its inside venous transfusion pressure balance needle is inserted to plastics infusion bottle bottom, the venous transfusion pressure balance needle be aseptic disposable syringe needle. The utility model discloses can solve the interior closed venous transfusion's of hyperbaric oxygen cabin exhaust problem well, keep gaseous unobstructed, make the interior pressure of the infusion bottle pressure interior with the hyperbaric chamber unanimously, avoid the pressure differential phenomenon. Let patient when accepting high -pressure oxygen therapy, can accomplish other venous transfusion medicament therapy, saved the valuable therapeutical time for patient.

Description

Sealed venous infusion pressure bascule in a kind of hyperbaric oxygen chamber

Technical field

This utility model relates to a kind of medical transfusion device, especially sealed venous infusion pressure bascule in hyperbaric oxygen chamber.

Background technology

Hyperbaric oxygen therapy be patient is placed oneself in the midst of in hyperbaric oxygen chamber carry out pressurizeing, oxygen uptake to be to reach the object of disease therapy.Along with hyperbaric oxygen therapy extensive use clinically, the nursing of hyperbaric oxygen chamber angular vein transfusion more and more receives attention and the concern of oxygen cabin nurse.Due to the diversity of the conventional environment that the physical environment in hyperbaric oxygen chamber and ambient atmosphere are depressed, make the venous transfusion in oxygen cabin have certain particularity, thus carry out hyperbaric oxygen chamber angular vein transfusion nursing, to ensure hyperbaric oxygentherapy carry out smoothly extremely important.Sealed venous transfusion in hyperbaric oxygen chamber, must keep infusion bottle external and internal pressure unanimously can normal infusion, if produce pressure differential, then there will be gas, liquid all flows to low-pressure area, and the serious consequences such as gassing, liquid spill.When starting to pressurize, in cabin, pressure increases gradually, and temperature raises gradually, in Maufee type dropper gas by compressing smaller volume, therefore fluid level is in higher position always, even can't see liquid dropping in dropper.Therefore, accompany cabin nurse that the fluid level in Murphy's pipe should be noted in pressure process to be adjusted to reduced levels, drip speed can observe.In oxygen cabin, pressure enters voltage stabilizing state after being pressurized to certain treatment pressure, and now pressure in oxygen cabin, temperature are all more constant, and patient starts oxygen inhalation therapy.Accompany cabin nurse the liquid level of Maufee type dropper should be adjusted to suitable level.At the uniform velocity instill after dripping speed by doctor's advice adjustment.After voltage stabilizing oxygen inhalation therapy is complete, in cabin, start decompression.Because pressure reduces during decompression, gas expansion in liquid bottles, Murphy's pipe, pressure increases, and liquid droping speed is accelerated and the decline of Murphy's intraluminal fluid face, has the danger making gas intravasation cause aeroembolism.Accompany cabin nurse before decompression, the liquid level in Murphy's pipe should be transferred to higher level, slow down liquid droping speed, and conscientiously check, close observation.At present, when carrying out sealed venous transfusion clinically in hyperbaric oxygen chamber, need standby minute hand head, minute hand head is inserted at the bottom of bottle from mouth of infusion bottle, exceed liquid level, folder closes the exhaustor of tube for transfusion upper end simultaneously, in the process, cannot reach the result changing transfusion pressure of the inside of a bottle at the bottom of minute hand head cannot be inserted to bottle sometimes.

Utility model content

The purpose of this utility model be to provide a kind of solve in hyperbaric oxygen chamber sealed venous transfusion time pressure differential hyperbaric oxygen chamber in sealed venous infusion pressure bascule.

For reaching above-mentioned purpose, concrete technical scheme of the present utility model is:

Sealed venous infusion pressure bascule in a kind of hyperbaric oxygen chamber, comprises plastic infusion bottle, and the transfusion device be communicated with plastic infusion bottle, characterized by further comprising: a venous transfusion pressure balance pin being inserted therein portion bottom described plastic infusion bottle.

Described venous transfusion pressure balance pin is aseptic disposable aspiration needle.

The beneficial effects of the utility model are:

The exhausting problem of sealed venous transfusion in hyperbaric oxygen chamber can be solved well, keep gas unobstructed, make in infusion bottle consistent with pressure in cabin, avoid pressure reduction phenomenon.Allow patient while accepting hyperbaric oxygentherapy, other venous transfusion medication treatment can be completed, for patient saves valuable treatment time.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

In the drawings, plastic infusion bottle 1, venous transfusion pressure balance pin 2, transfusion device 3.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, this utility model is described further.

Shown in Fig. 1, it is structural representation of the present utility model, from in figure, in the bottom of plastic infusion bottle 1, venous transfusion pressure balance pin 2 is inserted its position of having sterilized, the syringe needle of venous transfusion pressure balance pin 2 remains on the liquid level of liquid in plastic infusion bottle 1, the inner chamber of plastic infusion bottle 1 is communicated with outside, and the exhaust pipe clamp of transfusion device 3 is closed, change original ventilation direction thus, make the pressure in plastic infusion bottle 1 consistent with the pressure in hyperbaric cabin, avoid pressure reduction phenomenon.Described venous transfusion pressure balance pin 2 is the aseptic disposable aspiration needle of prior art products, wherein has used logical hole.

Claims (2)

1. a sealed venous infusion pressure bascule in hyperbaric oxygen chamber, comprises plastic infusion bottle (1), and the transfusion device (3) be communicated with described plastic infusion bottle (1), characterized by further comprising:

One is inserted therein the venous transfusion pressure balance pin (2) in portion from described plastic infusion bottle (1) bottom.

2. sealed venous infusion pressure bascule in hyperbaric oxygen chamber according to claim 1, is characterized in that:

Described venous transfusion pressure balance pin (2) is aseptic disposable aspiration needle.
