In-vitro amputated limb preservation bag capable of automatically releasing hydrogen ions

Abstract

The invention discloses an in-vitro amputated limb preservation bag capable of automatically releasing hydrogen ions. The in-vitro amputated limb preservation bag comprises a first outer bag, a secondouter bag, an inner bag and a reverse osmosis membrane bag; cold accumulation layers are respectively formed between the inner bag and the first outer bag and between the inner bag and the second outer bag; a temperature sensor clings to the inner wall of the inner bag, and the outer wall of the first outer bag is provided with a temperature display; the bottom of the first outer bag is providedwith a water drain pipe; and the reverse osmosis membrane bag comprises a bag body and a sampling reaction body, the bag body comprises a porous supporting layer and a compact layer, the sampling reaction body comprises a calcium hydride sampling part, a first reaction tank and a second reaction tank. The in-vitro amputated limb preservation bag is simple in structure; an amputated limb is preserved by adopting double layers, the cold storage of the amputated limb is realized due to the adoption of the cold accumulation layers, and the cold storage temperature can be monitored in real time, sothat the maximum demand for amputated limb storage is met; substances except for water and hydrogen are separated by a reverse osmosis membrane, so that the quality of a preserving liquid is guaranteed; and due to the adoption of the sampling reaction body, the aim of slow release is achieved, the release time of hydrogen is prolonged, and the survival rate of amputated limb replantation is increased.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to an isolated limb preservation bag capable of automatically releasing hydrogen ions. Background technique [0002] With the development of society, all kinds of mechanical equipment and transportation have been developed and improved rapidly, but more and more people will also have certain safety hazards, such as severed limbs and fingers. Patients with broken limbs are relatively common in clinical work, mainly including cutting disconnection, rolling disconnection, crushing disconnection, tearing disconnection and disconnection caused by explosive high-temperature drum. Most patients have Indications for emergency replantation surgery. The greatest significance of the preservation of severed limbs in vitro is to prepare for the replantation of severed limbs and lay a good foundation. However, some patients do not have the conditions for replantation of amputated li...

Problems solved by technology

[0004] During the process from the scene of the accident to the hospital, the conditions for the preservation of the severed limbs are limited. Usually, the severed limbs are stored in containers for preservation, and ice-water mixture is used for refrigeration, but the temperature of the refrigeration cannot be monitored and regulated in real time. The best cold storage effect for severed limbs cannot be guaranteed, and the container cannot seal the severed limbs well. The severed limbs are easily affected by the outside world, which cannot meet the better storage requirements, cannot guarantee a long storage time, and reduces the risk of severed limbs. The survival rate or function after limb replantation; and there is no simple equipment or device specially used to provide hydrogen for the storage solution in today's amputated limb storage containers. It is not convenient to add hydrogen to the storage solution alone. After the rich hydrogen is consumed, hydrogen needs to be added to the preservation solution again. Generally speaking, a certain amount of power is required, which not only consumes energy, but also wastes people's time, and the operation is also more troublesome.
