Description

Improved transfusion alarm

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to an infusion alarm of improvement.

Background

Intravenous infusion and fluid irrigation are widely applied operation items in modern medical activities, are particularly common in the process of anesthesia operations, and in the process of common operations, an anesthesiologist and a nurse can continuously observe and control the infusion process.

In some special occasions, such as when a patient is rescued or an emergency operation is performed due to a great blood loss during the operation, the administrative energy of anesthetists and nurses is limited, and in addition, the blood vessel condition of some patients is poor, the operation position and the action of intravenous infusion drugs can cause that even partial liquid in the intravenous infusion bag during the operation cannot normally flow downwards or the flow rate is slow or even stopped, so that the intravenous infusion drugs cannot effectively enter the body of the patient, thereby causing serious consequences such as intraoperative knowledge and even death due to serious complications. On the other hand, some endoscopic surgeries, such as cystoscopy and hysteroscopy, which require flushing, require a large amount of fluid, and the flushed fluid needs to flow into the flushing cavity under a certain volume and pressure. If the liquid is not enough, the effective flushing can not be carried out, thereby seriously influencing the operation process and endangering the benefits of patients.

The existing transfusion alarm is designed for blind people, intensive care patients, solitary old people, handicapped people, patients who are transfused for a long time or lie in bed by utilizing the laws of gravity, transfusion running empty and the like, and is an electronic alarm device for monitoring transfusion and prompting empty dropping. However, the existing transfusion alarm device often cannot predict the liquid empty condition in advance and the problems of too low liquid flow rate and even stagnation, and the like, so that the clinical danger still exists.

The prior art, for example, CN207429467U discloses a device in which the bracket is fixed and the light source and the light control switch are located on both sides of the liquid bag. When the device is used, the support and the liquid bottle are required to be arranged, then the position of the inclined beam is adjusted to enable the observation liquid bag to be placed right, the angle of the light-emitting device and the angle and the height of the light-operated reminding device are adjusted, one section of the line light beam of the light-emitting device is enabled to be emitted onto the observation liquid bag, and the other end of the line light beam is emitted onto the light display surface which is level to the blind hole. Because of the refraction of light, when there is liquid in the observation liquid package, the light beam that sees through the observation liquid package can not shine in the dark hole, and when liquid runs out in the observation liquid package, the light beam that sees through the observation liquid package will shine in the dark hole, makes light-operated reminding device send out the police dispatch newspaper through the photoswitch.

The fixing by the bracket has the advantages of being convenient for installing and fixing the device on a specific position, but has the defects that the distance between the light source and the photoswitch is too far, and stray light interference is easy to occur; because the light source and the light-operated switch are positioned at two sides of the liquid bag, the surface of the liquid bag easily reflects ambient light to cause the alarm to give an alarm by mistake; in the actual infusion treatment, a plurality of medicine solutions are often used for mixed treatment, when the medicine is added, the liquid bag needs to be repeatedly extruded to ensure that the liquid in the liquid bag is uniformly mixed, and the liquid bag is often extruded by family members of a patient, so that the device can send out wrong alarm reminding; the device can normally operate only when the light source and the light-operated switch form a specific angle, and the angle needs to be adjusted and confirmed every time of installation, so that the operation is complicated; improper contact by some patients can cause the light source to deflect from the light operated switch, which in turn can cause the device to fail; the whole device occupies too much volume, which is not beneficial to preservation and placement.

Furthermore, on the one hand, due to the differences in understanding to the person skilled in the art; on the other hand, since the inventor studied a lot of documents and patents when making the present invention, but the space did not list all details and contents in detail, however, this is by no means the present invention does not possess these prior art features, but on the contrary the present invention has possessed all features of the prior art, and the applicant reserves the right to increase the related prior art in the background art.
