Abstract
The utility model relates to a transfusion flow regulator, mainly comprising a shell, a slide rail, a roller, a roller shaft, a groove and a main part of a scale, wherein the shell is internally provided with the slide rail; the inner side of the slide rail is provided with the groove; the roller is embedded in the slide rail by the roller shaft; the side surface of the shell is provided with the scale; and the shell and the roller can be made of plastic materials. When in use, a guide tube is only needed to pass through the middle part of the shell of the regulator and making the roller to press the guide tube; when using hands to push the roller to move in the groove at the inner side of the slide rail, the access of the guide tube is controlled by the press of the roller, and the shift at which the roller is positioned is recorded by the scale at the side surface of the shell, thus achieving the purpose of accurately adjusting the liquid flow in the transfusion guide tube.
Description
Technical field
This utility model relates to a kind of infusion flow adjuster, relates to a kind of flow regulator that is installed on the transfusion catheter specifically, belongs to medical instruments field.
Background technology
The flow regulator that uses on the existing infusion set normally adopts plastic material to make, and is provided with inside groove and a roller in housing, utilizes the latus rectum of the rolling compressing change plastic catheter of roller, to reach the purpose of regulating fluid flow.But this traditional flow regulator exists certain defective and deficiency, the one, present general infusion set can accurately not determined flow, the number that drips that needs the operator to observe in the conduit kettle with eyes in the clinical manipulation is determined transfusion speed, inconvenient operation, and error is bigger; The 2nd, the slideway in the flow regulator is too smooth, when pulley is stuck in a site, be easy to generate the offset phenomena that skids, especially when indoor temperature is too high, transfusion catheter can the deliquescing along with the rising of temperature, and at this moment, the roller that the conduit latus rectum is regulated in compressing can slowly produce the displacement phenomenon, thereby cause the medicinal liquid flow velocity in the transfusion catheter to accelerate the life security that may jeopardize the patient when situation is serious.
The utility model content
The purpose of this utility model is in order to address the above problem, a kind of infusion flow adjuster is provided, this apparatus structure is simple, and production cost is low, and is easy and simple to handle, owing on the slideway of inclination inside groove, be provided with some tiny grooves, after the roller bearing of roller moved to pre-set position in the above, roller can not produce the nature offset phenomena because of skidding, and when the indoor environment temperature rising, during the transfusion catheter deliquescing, roller can not produce displacement along with the conversion of conduit; Owing to rule is arranged in the chute arranged outside of flow regulator, can be by the marked effect of rule, thus reach the purpose that allows user accurately regulate the fluid flow in the transfusion catheter, to satisfy the requirement of different patient's transfusion speeds.
In order to achieve the above object, this utility model is realized by following technological means.
A kind of infusion flow adjuster, it mainly includes housing, slideway, roller, roller shaft, groove, rule major part, wherein: be provided with slideway in enclosure interior, inboard at slideway is provided with groove, roller is embedded in the slideway by roller shaft, is provided with rule in the side of housing.
Described housing and roller can use plastic material to make.
During use, as long as conduit is passed the middle part of governor body, allow roller push down conduit, when usefulness hand propelled roller is mobile on the groove of slideway inboard, can control stimulating the menstrual flow of conduit by the pressure of roller, and can write down the residing gear of roller by the lateral rule of housing, thereby reach the purpose of the fluid flow in the accurate adjusting transfusion catheter.
This utility model mainly has following good effect and technical characterictic:
1, this apparatus structure is simple, production cost is low, easy and simple to handle, owing on the slideway of inclination inside groove, be provided with some tiny grooves, after the roller bearing of roller moved to pre-set position in the above, roller can not produce the nature offset phenomena because of skidding, and when the indoor environment temperature rising, during the transfusion catheter deliquescing, roller can not produce displacement along with the variation of conduit.
2, owing to rule is arranged in the chute arranged outside of flow regulator, can be by the marked effect of rule, thus reach the purpose that allows user accurately regulate the fluid flow in the transfusion catheter, to satisfy the requirement of different patient's transfusion speeds.

Accompanying drawing 2 is perspective view of a kind of infusion flow adjuster of this utility model.
As shown in the figure, the each several part title of above-mentioned a kind of infusion flow adjuster is represented by following Arabic numerals:
1. housing, 2. conduit, 3. slideway, 4. roller, 5. roller shaft, 6. groove, 7. rule.
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing for embodiment:
The specific embodiment
As shown in Figure 1 and Figure 2, a kind of infusion flow adjuster, it mainly includes housing 1, slideway 3, roller 4, roller shaft 5, groove 6, rule 7 major parts.
As shown in Figure 1 and Figure 2, be provided with slideway 3 in housing 1 inside, be provided with groove 6 in the inboard of slideway 3, roller 4 is embedded in the slideway 3 by roller shaft 5, is provided with rule 7 in the side of housing 1.
As shown in Figure 2, described housing 1 and roller 4 can use plastic material to make.
As shown in Figure 1 and Figure 2, during use, as long as conduit 2 is passed the middle part of governor body, allow roller 4 push down conduit 2, when with on the groove 6 of hand propelled roller 4 in the slideway inboard when mobile, can control stimulating the menstrual flow of conduit 2 by the pressure of roller 4, and can write down the residing gear of rollers, thereby reach the purpose of the fluid flow in the accurate adjusting transfusion catheter by the lateral rule 7 of housing.
