Abstract
The utility model relates to a medical heating device for transfusion, which belongs to a transfusion auxiliary device. The device is mainly composed of a heating bag, a housing body and an end cover, wherein, the housing body is cylindrical. The heating bag is positioned in the housing body, and the end of the heating bag is sealed by the end cover. The outside surface of the housing body is provided with a spiral slot with a semicircular cross section, and the lateral parts of the upper end and the lower end of the spiral slot are provided with fastening belts and fastening posts matched with the fastening belts. Air holes which are communicated with the inner part of the housing body are arranged on the lateral surface. The utility model has the advantages of simple structure and convenient use, and the utility model can continuously heat and does not generate pollution.
Description
This utility model is a kind of medical infusion solution heating device, belongs to the transfusion additional device.
In human transfusion, blood transfusion process, if ambient temperature is too low, the time that transfusion (blood) process continues is grown (often several hrs) again, the medicinal liquid or the blood that are significantly less than the blood heat so will make patient temperature descend, cause patient shivery, even bring other untoward reaction, and especially child, old patient, this type of reaction is more obvious.
The purpose of this utility model is a kind of disposable infusion warmer of design, is used with transfusion catheter, input liquid can be heated before entering human body, avoids patient untoward reaction to occur.
The designed disposable infusion warmer of this utility model mainly is made of heating bag, housing and end cap, housing is cylindrical tubular, heating bag is positioned at housing, its end is sealed by end cap, having the cross section in housing outer surface is semicircular spiral helicine groove, the button column that the sidepiece of its upper and lower end has cingulum and cooperates with it, have on the side surface with housing in the pore that communicates.
The groove of the disposable infusion warmer that this utility model is designed is left-handed groove.
The effective internal volume of housing of the disposable infusion warmer that this utility model is designed is 100～150cm
3
The disposable infusion warmer that this utility model is designed with pore be uniform pore, all the pore total sectional areas are not less than 6cm
2
The total length of the spiral grooves of the disposable infusion warmer appearance that this utility model is designed is in 300～460mm scope.
The designed disposable infusion warmer of this utility model is sealed in oxygen flow not, the not wet thoroughly packaging bag at ordinary times, need only during use it is taken out from this bag, above the conduit of housing helicla flute steering handle transfusion device is wrapped in, and conduit is fixed on the two ends of warmer with cingulum, after treating several minutes, warmer can heat by the transcatheter solution of convection current.
The advantage of the disposable infusion warmer that this utility model is designed is:
1. can continue to heat, remain on and to be heated human body carry out flowing through in the successive infusion process solution of conduit.
During the work of disposable infusion warmer, its internal temperature can reach more than 70 ℃.When infusion flow was 4ml/min (dripping about 85 droplets/minute of speed), if ambient temperature is 20 ℃, from about 27～32 ℃ of the effusive dropping liquid temperature of entry needle, the persistent period was not less than 3 hours; If ambient temperature is 1～3 ℃, the dropping liquid temperature can reach more than 10 ℃, and the persistent period also was not less than 3 hours.
2. safe in utilization, do not produce pollution.Why the disposable infusion warmer generates heat is not to rely on extra power (as electric energy), be to rely on the interior spontaneous heating material of device body behind ingress of air fully, oxidation reaction takes place and being accompanied by reduction and discharging heat, contingencies such as short circuit therefore can not occur, guarantees safe in utilization.The disposable infusion warmer is outer heating to the implementation of the solution in the transfusion catheter of flowing through, adverse effects such as therefore can not polluting, poison infusing.
3. easy and economical, and can guarantee the continuity of infusion process.
The designed disposable infusion warmer of this utility model is mainly used in the human transfusion of ambient temperature when being lower than 21 ℃, also can be used for other in particular cases.
Fig. 1 is the structure chart of the designed disposable infusion warmer of this utility model.
Fig. 2 is the user mode figure of Fig. 1.
In conjunction with specific embodiments the structure and the embodiment of the designed disposable infusion warmer of this utility model is described further with reference to the accompanying drawings below.
Embodiment
Disposable infusion warmer as shown in Figure 1 mainly is made of end cap 1, housing 2, heating bag 3, and housing 2 is cylindrical, have left-handed spiral helicine groove 4 on it, the cross section of groove 4 is semicircle, width 4mm, the pitch of spiral helicine groove 4 is 30mm, and the total length of groove 4 is 354mm.Effective internal volume of housing 2 is 110cm
3The upper and lower end in housing 2 outsides has cingulum 5 and the button column 7 that matches.The evenly-distributed air holes 6 that also to have 24 diameters on the housing 2 be 6mm.Heating bag 3 is the cloth bag of the spontaneous heating material of packing into, and heating bag 3 is positioned in the housing 2, and end cap 1 cooperates with housing 2 heating bag 3 is encapsulated in the housing 2.
When using, the conduit of transfusion device is wrapped in the groove 4 on the housing 2 of disposable infusion warmer, as shown in Figure 2, two ends cooperate with button column 7 by cingulum 5 fixes conduit.When flow of liquid during through conduit that the disposable infusion warmer is twined, by warmer liquid in the conduit is heated outward, temperature of liquid can be improved 8～20 ℃, as far as possible near body temperature, the untoward reaction when eliminating patient infusion.
That the disposable infusion warmer is sealed in before use is airtight, in the not wet thoroughly packaging bag, avoid the exothermic material of 3 li of heating bags to meet the air heating that reacts.And in use, just open.The disposable infusion warmer of this structure is simple in structure, easy for installation, safe in utilization, does not need outside resources, but can guarantee to continue in infusion process heating.And cost is low, all can use at clinical setting below 21 ℃, is ideal auxiliary delivery device.
