Problems solved by technology

This utility model solves the problem that the infusion needle is easy to slide and fall out, but because the infusion needle is still in the impact mode, fractures at the puncture site are more likely to occur, and the thread structure cannot achieve a better effect

Embodiment 1

[0045] Such as Figure 7-9 The intraosseous infusion set shown is composed of a protective cover 1, a sleeve 2, a combined infusion needle 3, a rotating spring 4, a locking device and an ejection device. The casing 2 is made of plastic material and has a cavity inside, which is mainly used to accommodate the rotary spring 4 and the combined infusion needle 3 . Sleeve 2 has an opening on one side of the infusion needle outlet, and a base 24 on the other side. There is a protective cover 1 at the opening. The function of the protective cover 1 is to protect the internal structure from contamination when the intraosseous infusion set is not in use. A handle 23 is provided on the sleeve 2 for clamping.

[0046] Such as Figure 1~5 As shown, the combined infusion needle 3 is composed of a puncture needle core 31 and a hollow infusion needle 32, all of which are made of medical high-strength alloy materials. For connection, the head end 312 of the puncture needle core is tapered;...

Embodiment 2

[0050] An intraosseous infusion set, the rest of which are the same as in Embodiment 1. The sleeve 2 is divided into tubes and is divided into an upper sleeve 21 and a lower sleeve 22. The two sleeves are connected by threads, and the upper sleeve 21 is provided with a hand-held The handle 23 contains the combined infusion needle 3 and the rotary spring 4 inside. The lower casing 22 is provided with a guide groove 25, and a limited depth valve 7 is also provided, and the limited depth valve is mainly composed of a regulator 71, a baffle plate 72 and a buckle 73. The depth limit valve is mainly based on the working principle of the utility knife handle. The external regulator 71 and the internal baffle 72 are connected through the guide groove 25. The position of the baffle 72 is adjusted by moving the regulator 71, and the buckle 73 is adjusted downward in the closed state. The machine 71 can move freely, and the adjuster 71 and the baffle 72 are fixed when pulled apart. The ...

Embodiment 3

[0052] An intraosseous infusion set, the rest of which is the same as that in Embodiment 1. There is an internal spline at the end 311 of the puncture needle core, and an external spline at the end 321 of the hollow infusion tube. The two are riveted together to prevent the hollow infusion needle 32 from penetrating into the bone. Come off with the puncture needle core 31 during quality. Markings are engraved on the surface of the casing 2. When the puncture needle core 31 is combined with the hollow infusion tube 32, the puncture needle core head end 312 is 4mm longer than the hollow infusion needle end 322, so that the skin and soft tissue can be pierced until the bone surface when punctured, and it can be drilled into the cancellous bone as a drill bit The infusion needle establishes an intraosseous channel and at the same time prevents soft tissue from being embedded in the infusion needle and causing the needle hole to be blocked.

Abstract

The invention relates to the medical equipment technical field, and discloses an intraosseous infusion device used for fast building a liquid recovery channel in emergency rescue; the intraosseous infusion device comprises a sleeve having a handle; the top of the sleeve is a pedestal; a combined infusion needle, formed by sleeving a puncture needle core with a hollow infusion needle, is contained in a cavity of the sleeve; a rotary spring is arranged in the sleeve; one end of the rotary spring is fixed on the pedestal, and the other end is fixed on a limit connector connecting with the upper portion of the tail of the puncture needle core; a slide way connected with the cavity of the sleeve is arranged in the handle, and clamped with a limit part; when the rotary spring is rotated and compacted, the limit part can clamp the limit connector through the slide way. The conventional impacting needle insertion mode is replaced by a rotary ejection mode, so the impact energy on a puncture position is small, and fracture can hardly happen; the head of the intraosseous infusion device is preset with threads, thus preventing infusion needle puncture position seepage and infusion needle slipping phenomenon.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an intraosseous infusion set for quickly establishing a fluid resuscitation channel during emergency rescue. Background technique [0002] There are mainly three ways of fluid resuscitation or drug infusion in clinical emergency rescue, including vein, artery and intraosseous infusion. Patients with traumatic hemorrhagic shock, severe dehydration, and severe dehydration in infants and young children. Such patients cannot quickly and effectively establish vascular emergency channels due to massive blood loss and fluid loss leading to venous collapse; in addition, severe edema, severe burns, and life-threatening In difficult situations such as epileptic seizures, shaking ambulances or helicopters, and dim light, intraosseous infusion has the advantages of simple operation, rapid and effective operation, and can establish an infusion channel in time, and apply rescue drugs a...
