Micro-cabinet with clot removal mechanism

Abstract

Nursing_Medical Technical Problem: One of the most commonly used equipment in hospitals is the microcentrifuge, which is used to administer a specific volume of fluid and dilute medications. The conventional method for removing blockages in the outlet port caused by small clots is to use a syringe to draw some serum and inject it directly into the Y-shaped port, or to use an automatic device to pull it firmly on the micro-tube to push the serum towards the outlet to remove the blockage. Solution: We designed a system that creates a flexible chamber between the Y-shaped tube and the blocking spool. By blocking the spool and squeezing the chamber, a volume of liquid flows towards the outlet and removes the blockage.

Description

Description of the invention Title of the invention Microset with chambered clot removal mechanism Technical background of the relevant invention The present invention relates to the field of medical equipment and a microset that can remove clots in the path of serum exit without using a syringe. Technical problem and stating the objectives of the invention In the hospital, the microset is a widely used tool that is used in all hospital departments to receive a controlled volume of fluids or to dilute medications. Patients who receive IV medications often experience blockages in the angiocatheter path between shifts. To clear the blockage, they apply some serum using a syringe or pen or a microset roller clamp and open the angiocatheter path. Using a syringe can increase the likelihood of transmitting infection to the patient, and for the medical staff who are at the patient's bedside, sometimes the nurse has to walk a relatively long distance to get the syringe. If we consider the number of times this process needs to be performed according to the number of patients, we realize the wear and tear of the medical staff, as well as the cost of waste disposal and storage of contaminated needles. The likelihood of needling of medical staff due to the use of syringes also increases.The method of using a roller clamp in most cases leads to damage to the clamp itself, which leads to the inefficiency of the microset and practically creates additional costs for the patient. The method of using a pen, due to the friction that occurs between the skin of the treatment staff and the microset tube, can lead to damage to the skin and loss of the integrity of the skin of the treatment staff and exposure to disease. Now, considering the disadvantages mentioned, in order to solve these problems, we have designed a system to eliminate the need to use needles and traditional methods and minimize other undesirable consequences.

Providing a solution to an existing technical problem along with an accurate, sufficient, and integrated description of the invention The present invention is a microcatheter with a chamber (Figure 1, Part 11), a cylinder with a height of 10 cm and a diameter of 2 cm, with a volume of 30 cc, made of flexible PVC, which is installed between the Y-shaped tube (Figure 1, Part 9) and the blocking spool (Figure 1, Part 17). If the microcatheter's exit path is blocked by a clot, a volume of serum can be sent to the angiocatheter with high pressure by closing the spool and squeezing the reservoir by hand. If it is not damaged, it will open the angiocatheter and relieve the blockage of the vein. Explanation of shapes, maps and diagrams Figure 1. Overview of the Microsat map Figure 2.

A clear and precise statement of the advantages of the claimed invention over prior inventions. Reducing the workload of medical staff and job attrition Increased speed of drug injection due to ease and speed in opening the angiocath pathway Reduced risk of needlestick injury due to not using a syringe to open the angiocath route Reducing the risk of transmitting infections and blood-borne diseases due to not using a syringe to open the angiocath passage Reducing costs related to needle production due to not using a syringe to open the angiocath route Reducing costs related to the storage of infectious and hazardous waste (production of safety boxes) due to the lack of use of syringes to open the angiocatheter Reducing costs related to the decontamination and disposal of this waste (safety boxes containing needles) due to the lack of use of syringes to open the angiocath route. Reduces the possibility of damage to the microstructure  Reducing the risk of injury and skin integrity of medical staff Description of at least one implementation method for implementing the invention We hang the microset from the serum base and fill the graduated chamber with the recommended amount of serum for drug dilution, hold the reservoir upside down until the cylindrical chamber is filled with serum, release it and vent the entire tube path and connect it to the patient's angiocatheter. When serum needs to be injected and the angiocatheter path is blocked, by closing the blocking spool and squeezing the chamber, the serum is forced towards the angiocatheter, opening the path and the serum enters the patient's body. Explicit mention of the industrial application of the invention Considering the annual consumption of microsatellites in the country, which is at least 9.6 million per year, and the provision of medical services in hospitals, blockage in the angiography path due to the lack of continuous serum is a natural occurrence. In order to eliminate it and facilitate the work of more than 215 thousand medical staff and reduce the transmission of infection, we have installed a flexible chamber to remove the blockage, and by using it, we can easily open the angiography path without spending time, equipment, and performing invasive work, reducing costs. The annual production of this type of microsatellite will be at least 9.6 million per year.
