Description

Heat preservation bag for replacement liquid

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a heat-insulating bag for replacement liquid.

Background

The blood purification process is to lead the blood of a patient out of the body and remove some pathogenic substances (toxins) in the blood through a blood purification device, thereby achieving the purposes of purifying the blood and treating diseases.

Blood purification plants use a blood purification machine CRRT for blood purification. CRRT (continuous renal replacement therapy) is a blood purification technique that can continuously remove solutes and support organ functions.

CRRT is driven by a pump to carry out extracorporeal circulation, excessive water is removed through the ultrafiltration of a high-flux dialyzer, large, medium and small molecular solutes are removed by the convection principle, and the CRRT has a plurality of unique advantages in the aspects of multi-organ function failure and the like.

Hypothermia is another complication of the most common CRRT, which is usually manifested as a cold whole body and no rise in body temperature, and mainly causes a large amount of blood in a patient to circulate outside the body when the amount of replacement fluid is increased in the CRRT process, so that heat is dissipated, and the temperature of the input replacement fluid is too low, so that hypothermia is caused.

The blood purifier is not provided with a device for heating the replacement liquid, so that the replacement liquid is often heated to avoid the phenomenon of low body temperature of a patient and then hung on a weighing hook of the blood purifier, the temperature of the heated replacement liquid is reduced quickly because the replacement liquid is not provided with a heat preservation device outside the replacement liquid, and the phenomenon of low body temperature of the patient cannot be avoided in the CRRT process.

SUMMERY OF THE UTILITY MODEL

1. Technical problem to be solved

Aiming at the problems in the prior art, the utility model aims to provide a heat-preservation bag for replacement fluid, which can preserve heat and heat the heated replacement fluid and avoid the phenomenon that the temperature of the replacement fluid is too low to cause low temperature of a patient.

2. Technical scheme

In order to solve the above problems, the present invention adopts the following technical solutions.

An insulation bag for replacement liquid comprises an insulation bag body wrapped outside a replacement liquid bag; the heat preservation bag body comprises a cloth bag layer, an inner heat preservation layer, a first sponge layer, a spiral heating wire, a second sponge layer, a lead and a switch; the cloth bag layer, the inner heat insulation layer, the first sponge layer and the second sponge layer are fixedly connected from outside to inside in sequence; the spiral heating wire is connected between the first sponge layer and the second sponge layer; one end of the lead is connected with the spiral heating wire, and the other end of the lead sequentially passes through the first sponge layer, the inner heat-insulating layer and the cloth bag layer and extends out of the cloth bag layer; the switch is electrically connected with the lead; the inner surface of the second sponge layer is in contact with the outer surface of the replacement fluid bag.

Preferably, the top end of the cloth bag layer is provided with a hanging hole.

Preferably, the inner heat-insulating layer is aluminum foil pearl wool.

Preferably, the weight of the heat preservation bag body and the replacement liquid bag does not exceed 290 g.

3. Advantageous effects

Compared with the prior art, the utility model has the advantages that:

(1) this practicality can keep warm to the replacement liquid that has heated through setting up of interior heat preservation, reduces the heat of replacement liquid and scatters and disappears to avoid the replacement liquid temperature to hang down excessively and lead to the patient to appear microthermal phenomenon.

(2) This practicality can heat the replacement liquid of placing in this internal replacement liquid bag of insulated bag through the setting of spiral heater strip.

(3) This practicality makes the spiral heater strip can carry out the even heating to the replacement liquid in the liquid bag through the setting on first sponge layer and second sponge layer through the second sponge layer.

Drawings

Fig. 1 is a schematic cross-sectional structure of the present invention.

The reference numbers in the figures illustrate:

1 heat preservation bag body, 2 sack layers, 3 interior heat preservation, 4 first sponge layers, 5 spiral heater strips, 6 second sponge layers, 7 wires, 8 switches, 9 hang the hole.

Detailed Description

Please refer to fig. 1, which illustrates a heat preservation bag for replacement fluid, comprising a heat preservation bag body 1 wrapped outside the replacement fluid bag; the insulating bag body 1 comprises a cloth bag layer 2, an inner insulating layer 3, a first sponge layer 4, a spiral heating wire 5, a second sponge layer 6, a lead 7 and a switch 8.

The cloth bag layer 2, the inner heat insulation layer 3, the first sponge layer 4 and the second sponge layer 6 are fixedly connected from outside to inside in sequence.

Interior heat preservation 3 can keep warm to the replacement liquid that has heated, slows down the heat of replacement liquid and scatters and disappears to avoid the replacement liquid temperature that has heated to reduce and lead to the patient to appear microthermal phenomenon too fast.

The spiral heating wire 5 is connected between the first sponge layer 4 and the second sponge layer 6, and the second sponge layer 6 enables the spiral heating wire 5 to uniformly heat the replacement liquid in the replacement liquid bag.

Wire 7 one end is connected with spiral heater strip 5, and the other end passes first sponge layer 4, interior heat preservation 3 and sack layer 2 in proper order and extends to outside sack layer 2.

The switch 8 is electrically connected with the lead 7; the inner surface of the second sponge layer 6 is contacted with the outer surface of the replacement liquid bag, and the spiral heating wire 5 is controlled by the switch 8 to heat the replacement liquid.

The top end of the cloth bag layer 2 is provided with a hanging hole 9, which is convenient for hanging the replacement liquid in the thermal insulation bag body 1.

The inner heat-insulating layer 3 is made of aluminum foil pearl wool.

The weight of the heat preservation bag body 1 and the replacement liquid bag is not more than 290g, so that the influence of the weight of the heat preservation bag body 1 and the replacement liquid bag on the weighing detection of the liquid in the replacement liquid by the blood purifier is avoided.
