Description

Transfusion pressure warning unit

Technical field

This utility model relates to a kind of therapeutic medical assistive device, specifically a kind of transfusion pressure warning unit.

Background technology

Infusion is treatment means conventional in clinical treatment work.At present, most of infusion process is generally by patient or another name is accompanied and served personnel or medical personnel's moment is observed medicinal liquid residual volume situation, but also usually fails to find in time, causes a large amount of manpower wastes, inefficiency.In the time of patient infusion, need patient or its entourage to keep a close eye on transfusion progress, prevent because there is dripping empty phenomenon, if liquid is totally lost and is failed to find in time and change liquid or pull out syringe needle, there will be the situation of air intravasation, increase unnecessary misery to patient, even jeopardize patient's life.In order to alleviate patient or its entourage's burden, avoid the adverse consequences that causes because of human negligence, successively someone has carried out attempting based on the technology of various principles, common are electrode method, level detection method, drop count technique and weight method.Whether wherein electrode method is to insert two electrodes from mouth of infusion bottle, utilize the electric conductivity of medicine to carry out inspecting bottles inner liquid medicine and be finished, and this method easily makes medicinal liquid contaminated, does not meet security regulations.Level detection method is that the photoelectric sensor by being fixed on body or tube for transfusion outside detects liquid level, thereby judges whether transfusion finishes, and for being fixed on infusion bottle device with it, now universal transfusion bag is inapplicable; For the device being fixed on tube for transfusion, start interval to medical personnel response from reporting to the police shorter, there is security risk.Drop count technique is by photoelectric sensor, drop counted and reported to the police the moment in conjunction with initial drop total amount judgement, total number of drops when this method need to be added up every kind of specification transfusion bag transfusion in advance, cumbersome, and size and the speed of drop is all not quite similar during due to each transfusion, this has just introduced very large deviation to system, causes the reduction of system reliability.Existing check weighing method utilizes spring scale or LOAD CELLS to realize, and all has that precision is low, the problem of poor reliability.Also have some infusion alarm systems to intend use terminal unified management, when multiple like this berths are called out simultaneously, nurse has little time response, and complexity is installed, involves great expense, and is unfavorable for promoting at small-middle hospital.

It is CN102526827A that State Intellectual Property Office discloses publication number on July 4th, 2012, the application for a patent for invention document of utility model title solar energy infusion alarm, this application document is made up of battery, alarm and spring scale, and implementation step is that the position that spring scale is measured to sky infusion bottle is denoted as the point into A; The position of measuring full infusion bottle with spring scale is denoted as the point into B; On spring scale from A point to B point fixed conductor sheet, as static contact; The number of degrees iron plate of spring scale is as movable contact spring; A wire on alarm is connected on static contact, and another root is connected on movable contact spring; The two-stage of solaode is connected on static contact and movable contact spring; When consumption gradually of the liquid level in infusion bottle, until the A point on spring scale when contacting with B point, circuit disconnects, and alarm sends alarm sound; Technique scheme can remind transfusion person to notice that liquid level changes.The technical scheme of above-mentioned patent is different from present patent application, and it has complex structure, the easy shortcoming of reporting by mistake.

Summary of the invention

The purpose of this utility model is to provide a kind of easy and simple to handle, transfusion pressure warning unit that warning precision is high.

For achieving the above object, the technical scheme that this utility model adopts is:

Transfusion pressure warning unit, its master is made up of ring type pressure transducer, shell and single-chip microcomputer, the speaker established in the enclosure, shell is provided with two above in order to place the through hole of infusion bottle, described ring type pressure transducer is located at the lower port place of each through hole, the inner surface of described through hole and the shape of infusion bottle are suitable, and the bottleneck of infusion bottle passes from the lower port of through hole, the body of infusion bottle is supported on ring type pressure transducer; Ring type pressure transducer sends the pressure information of infusion bottle to single-chip microcomputer, and single-chip microcomputer starts speaker according to pressure information and reports to the police; The corresponding starting switch being electrically connected with single-chip microcomputer of ring type pressure transducer in each through hole.

Described through hole is provided with four, and the aperture of four through holes is different, and four through holes are used for respectively placing the infusion bottle that volume is 50ml, 100ml, 250ml, 500ml.

The degree of depth of described through hole is less than the height of infusion bottle, and this structure facilitates infusion bottle to put into and take out in the through hole with pressure warning unit in transfusion.

Described shell is provided with battery main switch.

The four sides of described shell is respectively equipped with alarm lamp, and described alarm lamp is electrically connected with single-chip microcomputer.

Four jiaos, the top place of described shell is provided with suspension ring.

Described single-chip microcomputer adopts SC91F72B type single-chip microcomputer.

The beneficial effects of the utility model: owing to adopting above-mentioned version, when transfusion, as long as infusion bottle is put into corresponding through hole and started corresponding starting switch, save the program that alarm device is arranged, easy to operate; Owing to having set up the through hole of multiple different model infusion bottles, so can be suitable for the infusion bottle of different model.
