Abstract
The utility model discloses a kind of infusion bags, including several mutually isolated chambers, are isolated between each chamber by weak welding rod；Two weak welding rods are set between the chamber, isolation buffer chamber is provided between two weak welding rods, weak welding rod is wavy far from isolation buffer chamber side.The weak welding rod between each chamber is set wave-like by the utility model double-chamber transfusion bag, has adjusted the stress distribution of weak welding rod, improves the efficiency that weak welding rod is opened；By reinforcing the weld strength of weak welding rod, improve that weak welding rod is anti-to open by mistake the ability opened；To reduce the task difficulty of medical staff, the safety of multi-cavity chamber infusion bag is improved.
Description
Technical field
The utility model relates to a kind of multi-cavity chamber infusion bag, especially a kind of novel weak weldering spacer structures multi-chamber infusion
Bag.
Background technique
Currently, the dual cavity infusion bag of hospital or medical space is (containing medical fluid and powder liquid infusion bag or medical fluid and medicine
Liquid infusion bag) infusion products are a kind of immediate dispensing infusion products, double-chamber transfusion bag product includes being equipped with 2 chamber two
Point, centre is separated with weak welding rod, before use, two chambers are not connected.In use, medical staff suitably firmly squeezes 2 chambers,
Weak welding rod 1 can be opened, for clinical use after being sufficiently mixed the drug of 2 chambers.Existing double-chamber transfusion bag such as Fig. 1
Shown, opening force is difficult to control；If the weld strength of weak welding rod 1 is high, clinical tasks are difficult to squeeze weak welding rod 1；If weak weldering
The weld strength of item 1 is lower, although being easy to squeeze weak welding rod 1, it is easy to happen in transportational process and opens by mistake the case where opening, is increased
The task difficulty of clinical use is added.
Utility model content
It is unique that the purpose of the utility model is to provide a kind of structure novels, easy to use, and can reduce task difficulty
Double-chamber transfusion bag；The specific technical proposal is:
A kind of novel weak weldering spacer structures multi-cavity chamber infusion bag, including several mutually isolated chambers, each chamber
Between be isolated by weak welding rod；Two weak welding rods are set between the chamber, it is slow that isolation is provided between two weak welding rods
Chamber is rushed, weak welding rod is wavy.
Further, the weak welding rod is straight flange close to isolation buffer chamber side.
Further, the most narrow place width of the weak welding rod is at 6 to 8 millimeters.
Further, the weak welding rod close to the wave top of the isolation buffer chamber radius of corner 5 to 8 millimeters it
Between.
Further, the outer surface of the weak welding rod is provided with cell structure.
Further, the both ends of the weak welding rod are provided with reinforcement part.
The novel weak weldering spacer structures multi-cavity chamber infusion bag of the utility model sets the weak welding rod between each chamber to
It is wavy, the stress distribution of weak welding rod is had adjusted, the efficiency that weak welding rod is opened is improved；It is strong by the welding for reinforcing weak welding rod
Degree, improves that weak welding rod is anti-to open by mistake the ability opened；To reduce the task difficulty of medical staff, multi-cavity chamber infusion bag is improved
Safety.

In figure: 1, weak welding rod；2, real weld ddge；3, isolation buffer chamber；4, first chamber；5, second chamber.
Specific embodiment
The utility model is made a more thorough explanation below with embodiment.The utility model can be presented as it is a variety of not
Same form, should not be construed as limited to the exemplary embodiments described herein.
The spatially relative terms such as "upper", "lower" " left side " " right side " can be used herein for ease of explanation, for saying
Relationship of the elements or features relative to another elements or features shown in bright figure.It should be understood that in addition in figure
Except the orientation shown, spatial terminology is intended to include the different direction of device in use or operation.For example, if in figure
Device is squeezed, and is stated as being located at other elements or the element of feature "lower" will be located into other elements or feature "upper".Cause
This, exemplary term "lower" may include both upper and lower orientation.Device, which can be positioned in other ways, (to be rotated by 90 ° or is located at
Other orientation), it can be interpreted accordingly used herein of the opposite explanation in space.
As shown in Figure 2 and Figure 3, the double-chamber transfusion bag in the present embodiment, including two mutually isolated chambers, the first chamber
It is isolated between room 4 and second chamber 5 by weak welding rod 1；It is provided with two wavy weak welding rods 1 between two chambers, two
Isolation buffer chamber 3 is provided between weak welding rod 1.The periphery of infusion bag is real weld ddge 2.After setting wavy for weak welding rod 1, prolong
The length for having grown weak welding rod 1 improves the intensity of weak welding rod 1；Utilize the wavy stress for having adjusted weak 1 each section of welding rod point
Cloth makes the stress generated when pressing cavity be concentrated mainly on the top of wave of the weak welding rod 1 close to isolation buffer chamber 3；It reduces
Squeeze the difficulty of weak welding rod.Weak welding rod 1 uses higher weld strength, reaches the 40% to 60% of real weldering intensity；It can effectively avoid
It is generated in transportational process and opens by mistake the case where opening.It is illustrated by taking double-chamber transfusion bag as an example in the present embodiment；The utility model is public
The weak welding rod structure opened can be also used for the infusion bag of three mutually isolated chambers or more.
It is wavy that the shape of weak welding rod 1, which can be two sides shown in Fig. 2,.It is also possible to close shown in Fig. 3
3 side of isolation buffer chamber is straight flange.When close to 3 side of isolation buffer chamber be straight flange when, from first chamber 4 unlatching after, liquid or
Gas enters isolation buffer chamber 3；Since 3 inner wall of isolation buffer chamber is straight line, anti-pressure ability is stronger, it is not easy to open from this direction
It opens.It needs to squeeze from second chamber 5, opens the weak welding rod 1 of lower section, achieve the purpose that first chamber 4 is connected to second chamber 5.
In this way, opening process is divided into two steps, it is more advantageous to and avoids maloperation.
In order to avoid opening force is too big, the most narrow place width of weak welding rod 1 should be controlled at 6 to 8 millimeters.
The fillet of weak wave top of the welding rod 1 far from isolation buffer chamber 3 does not require specifically.Weak welding rod 1 is close to isolation
The radius of corner of the wave top of cushion chamber 3 both guarantees can there is stronger stress when squeezing sap cavity between 5 to 8 millimeters
It concentrates, and weak welding rod 1 can be made to crack first in the near top of the wave close to isolation buffer chamber 3, and then weak welding rod 1 is punished
It opens, is connected to isolation buffer chamber 3.
In order to facilitate crawl, the outer surface of weak welding rod 1 is provided with cell structure or salient point array, increases the part
Frictional force.
The both ends of weak welding rod 1 and 2 junction of real weld ddge are easy to produce stress concentration, can be arranged at the both ends of weak welding rod 1
There is reinforcement part, increase the bonding area at the position, avoiding opening in the near sites influences real weld ddge 2, causes leakage.
Above-mentioned example is only intended to illustrate the utility model, and in addition to this, also there are many different embodiments, and these
Embodiment be all those skilled in the art after comprehension the utility model thought it is also envisioned that therefore no longer arranging one by one herein
It lifts.
