Description

Dry powder barrel support

Technical Field

The invention relates to the technical field of medical instruments, in particular to a dry powder barrel support.

Background

In the hemodialysis process, the blood and the dialysate are subjected to solute exchange through a dialysis membrane, harmful substances in the dialysate can directly enter the blood, and endotoxin and fragments in the dialysate can pass through the dialysis membrane and enter the body of a patient to cause a heat source reaction, so that the patient generates symptoms such as hypotension, muscle spasm, headache, fever and the like, and the serious shock can be caused. Long-term endotoxin stimulation can cause long-term complications of dialysis, such as chronic inflammatory reaction and the like. Among them, chronic inflammatory reactions are strongly related to heart diseases, malnutrition and erythropoietin resistance in renal failure patients, and may be a significant life-threatening factor for patients. Ensuring the quality of the dialysis fluid is therefore a fundamental requirement of modern hemodialysis. The dialysis liquid is formed by mixing two concentrated solutions of back-osmosis water and A, B according to different proportions. The pH value of the B concentrated solution is slightly alkaline, and is more suitable for bacterial reproduction, so that the B concentrated solution has a direct relation with the bacteria and endotoxin superscripts of the dialysate.

There are two ways of supplying the concentrate B in the existing hemodialysis machine: directly providing liquid concentrated solution and online dry powder to dissolve into liquid concentrated solution on line. At present, the online dissolving mode of the dry powder is the accepted optimal liquid supply mode of the B concentrated solution. Its advantage does: the dissolved dialysate can be used immediately, so that the bacteria reproduction probability can be reduced to the maximum extent, and the microbial quality of the final dialysate can be ensured. The use of on-line dry powder on hemodialysis machines requires a dry powder bucket rack support.

The prior art lower bracket is shown in figure 1 of the attached drawings of the specification, a detection part of a proximity switch is arranged on the lower surface of a connecting plate, and a detected part is arranged at the outermost end of a rotary switch. The disadvantages of this support are: 1. when the connector is not in a working state, the small connector part is directly exposed in the air, dust falls or artificial touch is caused, and a sanitary problem exists; 2. when the hemodialysis is in a working state, the movable switch is easily opened due to careless touch, so that the dry powder barrel is not fixed stably; 3. when the equipment is in a cleaning state, due to the problems of the support, the installation sequence of the connectors can be various, if the connectors are not installed according to a specific sequence, the connectors are likely to be opened when not installed, and liquid is likely to splash; 4. the metal connecting pieces are too many, so that liquid contact is difficult to avoid in a working state, and the metal connecting pieces are easy to rust after long-term use.

As shown in figure 1, as shown in figure 1, the structure of the dry powder barrel bracket of the prior art is such that the inductive switch 21 of the prior art is arranged on the lower bracket base 16, the detection part is arranged on the rotary cover plate 24, the detected part is arranged at the tail part of the base 16, no matter whether the connector is connected on the lower bracket or not, as long as the tail part of the rotary cover plate 24 and the tail part of the base 16 are close to the inductive switch, the cleaning error is often generated, the phenomena of liquid leakage and the like occur, the waste is caused, and the medical staff is easy to be in a mess. And because the inductive switch 21 is disposed on the base 16 and the rotating cover 24, the upper bracket 17 cannot be used commonly with the base 16 of the lower bracket.

Disclosure of Invention

Aiming at the defects in the prior art, the invention aims to provide a dry powder barrel support, and the utility model provides a dry powder barrel support which has low production cost and is simple to maintain and replace.

In order to solve the technical problems, the invention provides the following technical scheme:

a dry powder barrel support comprises an upper support and a lower support which are matched up and down, wherein the lower support comprises a base and a connecting part, and the bases of the upper support and the lower support are the same.

Preferably, the lower support base and the upper support comprise two extending clamping jaws, clamping grooves are formed in the inner sides of the clamping jaws, and the back faces of the clamping jaws are provided with anti-shrinkage cavities.

Preferably, the depth of the shrink-proof clearance varies according to the transverse thickness of the jaws.

Preferably, an upper connector and a lower connector are respectively arranged on the upper support and the lower support, a proximity switch is arranged on the lower support and comprises a detection part and a detected part, the detection part is arranged on a connecting part of the lower support, the detected part is arranged on the upper connector, and the upper connector is detachably and movably connected with the upper support, the lower connector and the lower support.

The base of the upper bracket and the base of the lower bracket are the same, the base of the upper bracket and the base of the lower bracket of the dry powder barrel bracket in the prior art are different, so that two sets of molds are required to be opened during production, the production cost is very high, the base of the upper bracket and the base of the lower bracket are the same, one set of molds are enough during production, the production cost of products is reduced, and the universal dry powder barrel bracket is universal, so that all the dry powder barrel brackets are convenient to replace, the upper bracket or the lower bracket base does not need to be distinguished, and the dry powder barrel bracket can be directly installed.

The back of upper bracket or lower carriage base jack catch of this technical scheme sets up prevents the shrink and keeps away the sky, prevent at first that shrink and keep away the empty deformation problem that sets up whole part in can solving the cooling process of moulding plastics, and this technical scheme's the position that prevents the shrink and keep away the sky sets up more ingenious, because medical equipment's particularity, must regularly clean, the setting certainly can increase medical personnel's cleaning work load on the surface, so this technical scheme prevents the shrink and keeps away the empty setting at the back of jack catch, so not only keep the surface of product bright and clean, and do not have the influence to the bulk strength of product, and prevent the shrink and keep away the empty setting on the jack catch, increased the elasticity of jack catch from a certain extent, it is more convenient to use.

The depth of the shrink-proof clearance is changed according to the transverse thickness of the clamping jaws, so that the shrink-proof clearance can be set to be deeper at the wide position of the clamping jaws, the allowable variable can be larger, and the requirement of processing the variable is met according to local conditions.

The base and the upper bracket have the same structure. The design aims at that the base and the upper bracket can use the same die when producing products, so that the cost is saved; meanwhile, damage occurs in use, and the replacement cost is correspondingly reduced.
