Infusion survival kit in marrow cavity

Abstract

The invention discloses an infusion survival kit in a marrow cavity, which comprises a base, a puncture needle, an ejection main cylinder, an ejection device, a mandrel, an upper cover and a rear handle, wherein the ejection device is positioned in the ejection main cylinder; the ejection device comprises a thrust spring, a thrust shaft and a steel ball lock structure; the thrust shaft is a solid body, a concave hole is formed at the lower part of the thrust shaft, and a magnetic connector is arranged in the thrust shaft; the thrust shaft is connected with the puncture needle through the magnetic connector; a concave hole is formed at the upper part of the thrust shaft; and the lower part of the mandrel can be placed in the concave hole at the upper part of the thrust shaft. The principle is as follows: by applying the vascular access technology in the marrow cavity, the puncture needle can penetrate through the bone to enter the marrow cavity in a few seconds, and a trocar can continuously infuse first-aid liquid to establish an infusion channel in a short time, thereby gaining the rescue time. The infusion survival kit has small volume, does not need to take electricity as power, is convenient to carry, is safe and reliable in use, can greatly shorten the time for establishing the infusion channel, and improves the rescue success ratio.

Description

technical field [0001] The invention relates to a new type of emergency medical device, more specifically to an emergency device for intraosseous cavity transfusion. Background technique [0002] In the clinical rescue of critically ill patients, the key is to establish a good venous channel, which is the prerequisite for determining whether the rescue is successful, especially for patients with shock, massive blood loss, and extreme dehydration, which may cause a series of serious microcirculation disorders and subcutaneous vein collapse. , vasoconstriction, blood stasis, high viscosity, increased permeability, and obese patients' veins are not obvious, which brings great difficulties to medical staff for venipuncture. The unsuccessful puncture causes the doctor to be unable to administer medicine, which directly affects the rescue result, or the puncture time is prolonged, which delays the rescue time. According to statistics, if the infusion channel can be established in...

AI Technical Summary

Problems solved by technology

However, if the puncture is unsuccessful, the doctor cannot administer the drug, which directly affects the rescue result, or the puncture time is prolonged, and the rescue time is delayed.

According to statistics, if the infusion channel can be established in the first 10 minutes for the wounded in wartime hemorrhagic shock, the casualty rate will be greatly reduced, while the traditional intravenous infusion takes an average of 12 minutes to establish
