Description

Suction metering device of medical aspirator

Technical Field

The utility model relates to the technical field of medical equipment, concretely relates to suction metering device of medical aspirator.

Background

Bleeding is a common complication in surgical operations, and the amount of bleeding directly determines the fluid replacement strategy of an intraoperative anaesthetist: if the amount of bleeding is small, only crystal or colloidal fluid needs to be supplemented; if the amount of bleeding is large, blood products need to be infused. The bleeding volume may be indirectly using a suction bag. The suction bag is used for sucking and removing the contents in hemorrhage, exudate, pus and thoracic organs in the operation, so that the operation is clear and the pollution chance is reduced. The principle of the suction bag is that the negative pressure state of the suction head is manufactured by a certain method, so that substances outside the suction head can be extruded to the suction head by atmospheric pressure, and the suction effect is achieved.

There are currently a number of methods to estimate the amount of bleeding during anesthesia: scales are marked on the suction bag, so that the scale is easy to find in actual work, and the error between the estimated bleeding amount and the actual bleeding amount is larger; secondly, the suction bag is poured into the measuring cup, although the method is more accurate, the risk of polluting an operating room and infecting medical staff due to the fact that blood products are poured and measured can be avoided; and (III) the precision measurement aspirator is high in cost and is generally only used for operations expecting a known massive hemorrhage, such as liver transplantation, brain tumor operations and the like.

Therefore, aiming at the defects existing in the bleeding volume measurement in the current operation, the suction metering device of the medical aspirator is needed to be provided, the blood volume can be measured accurately, and the expenses of hospitals and patients are saved.

Detailed Description

The technical solution of the present invention will be described clearly and completely through the following detailed description. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-2, a suction metering device of a medical aspirator, which is used in cooperation with a negative pressure device, comprises a measuring device 1 and a suction bag 2, wherein the suction bag 2 comprises a bag cover 21 and a bag body 22, and the bag cover 21 and the bag body 22 are integrally formed and are sealed and airtight. The bag cover 21 is a hard shell 112, the bag body 22 is similar to a plastic bag, the bag body 22 is placed in the suction bottle, and the bag cover 21 is sealed and arranged on the flat opening of the suction bottle. The top of the bag cover 21 is provided with a suction inlet 211 and a suction outlet 212, the suction inlet 211 is used for connecting with a bleeding part of a patient, and the bleeding amount is sucked into the bag body 22 from the suction inlet 211; the outlet 212 is used to connect with a negative pressure device, so that the negative pressure in the bag body 22 is the same as the negative pressure provided by the negative pressure device, and thus the operations of sucking blood volume, sucking phlegm or draining can be performed. The negative pressure generated by the negative pressure device sucks the bleeding part of the patient in sequence through the catheter and the suction port 211 and enters the bag body 22. The measuring device 1 is used for measuring the amount of bleeding in the bag body 22, and when the measuring device is used, the suction bag 2 is directly hung on the measuring device 1 for measurement; when not in use, the utility model can be taken off directly.

The bag body 22 is formed by sealing and pressing two bag body layers, and the insertion hole 221 is arranged at the outer end edge of the pressing part of the two bag body layers. The two-layer bag layer is laminated at the outer end and is equivalent to two separated bag layers, and the insertion hole 221 is arranged at the position of the two-layer bag layer, so that the sealing performance of the bag body 22 is not influenced. The insertion holes 221 can be formed in the left side, the right side and the lower edge of the lower portion of the bag body 22, the number of the insertion holes 221 can be set according to actual conditions, and the position of the insertion holes 221 cannot influence the sealing performance of the bag body 22. The insertion hole 221 may be circular or square, as long as it is sufficient that the hook 111 can be conveniently hung in the insertion hole 221. Preferably, the insertion holes 221 are formed at the lower edge of the pocket 22, and the number of the insertion holes 221 is one. When the measuring device 1 measures, the bag body 22 is directly turned over for measurement, so that the jack 221 is conveniently found, the measuring device 1 is easy to measure, and the measuring efficiency is improved.

The measuring device 1 can be a meter 11, wherein the meter 11 comprises a shell 112, a spring 114, a cylinder 115 and a hook 111, the spring 114 is sleeved on the cylinder 115, the upper end of the spring 114 can be in releasable elastic support against the top end of the cylinder 115, and when the spring 114 is stressed and compressed, the upper end of the spring 114 can be in releasable connection with the top end of the cylinder 115; the lower end of the spring 114 is releasably resiliently urged against the base of the post 115. The hook 111 is fixedly connected or integrally formed on the bottom of the column 115. When the hook 111 is hung on the bag body 22, the hook 111 drives the column 115 to move downwards, and the column 115 simultaneously drives the spring 114 to compress downwards. Through setting up couple 111, make things convenient for to be connected between couple 111 and the jack 221, and then conveniently measure the amount of bleeding. The housing 112 is transparent and scales are provided on the surface of the housing 112. When the cylinder 115 moves downward together with the spring 114, the position of the top end of the cylinder 115 is indicated, and the data of the amount of bleeding and the suction bag 2 is obtained.

Through-hole 113 has been seted up at casing 112 top, and through-hole 113 just can hold putting into of finger, makes things convenient for the measurement of counter 11, also prevents the influence of external to measuring device 1 measurement value among the measurement process.

Before meter 11 is used, meter 11 is zeroed: the top of the cylinder 115 needs to be aligned with the zero graduation line, and the extending direction of the spring 114 needs to be aligned with the pulling direction. Before the operation, the gauge 11 measures the unused aspiration bag 2; in the operation, (1) the bag body 22 is put into the suction bottle, the bag cover 21 is covered on the suction bottle mouth, and the bag cover 21 is tightly buckled on the suction bottle by the buckle; the suction inlet 211 is connected with the bleeding part of the patient through a catheter, and the suction outlet 212 is connected with the negative pressure device, so that the negative pressure in the bag body 22 is the same as the negative pressure provided by the negative pressure device, and the blood volume suction operation is performed; (2) closing the negative pressure device, opening the buckle, taking down the conduit, covering and sealing the suction inlet 211 and the extraction outlet 212 by the cover provided by the conduit, and taking out the suction bag 2 with negative pressure; the bag body 22 with the bleeding amount is directly hung on the hook 111 of the meter 11 through the jack 221, and the measurement is carried out; (3) comparing the data of the non-suction bag 2 with the data of the suction bag 2 sucking the bleeding amount, and obtaining the difference value of the two data, namely the bleeding amount of the patient. In actual use, the suction bag 2 will have different qualities depending on the size and material, but the quality part is relatively constant.

The utility model provides a pair of medical aspirator's attraction metering device should attract metering device to measure the amount of bleeding in attracting bag 2 through the counter, can more accurate measurement amount of bleeding, facilitates the use and can save hospital, patient's spending.
