Description

BLOOD BAG VALVE
BREAKER
Technical Field
The invention belongs to the field of medicine, and relates to devices-gadgets for closing and opening containers in the form of containers-bags for storage, transport and processing bodily fluids. According to the International Patent Classification (IPC) the invention is classified into class A61M 39/00 which defines tubes, tubes connections, tubes connectors, valves, distribution units and likes, specially adapted for medical use, or into class A61M 39/22 which defines valves or valve parts. The invention may also be classified into class B65B 7/00 which defines manual or mechanical devices for opening closed containers.
Technical Problem
The technical problem solved by this invention is how to design a device for breaking blood bag valves, in order to, by applying electromotor coupled with excenter by excenter-lever mechanism, to whose push rod a specially designed fork for reception an¾Tbreaking the closed-check outlet valve on the blood bag is connected, enable fast, simple and safe opening of the valve for leakage of the blood separates from the bag. Background Art
By review of patent and non-patent documentation, the inventors did not find similar solutions for blood bag valve breakers. It is usual for these valves, after the performed centrifugation, to be broken manually. This procedure is complicated, requires substantial effort and may be painful and risky for the person operating the blood separator.
By review of the patent documentation, within classes A61J 1/00, A61J 1/10, A61M 1/00, A61M 1/02, A61M 39/00 and A61M 39/22, in the national patent corpus of Republic of Serbia, no relevant documents were found.
By review of the patent documentation, within classes A61J 1/00, A61J 1/10, A61M 1/00, A61M 1/02, A61M 39/00 and A61M 39/22, in international bases EPO and the American patent organization base, the following documents were found:

EP-B patents: EP 0 348 682 Bl;
Rest of the world: JP 9108303 A and JP 2005192784 A.
By detailed analysis of the stated documents it was determined that all subject patents relate to: design of blood separators, connector of medical bags for fluids, design of valvesy, liquid separator, device for storing the bag and holding the bag and the centrifugal separation procedure. All documents stated in the background art, based on the presented reasons may be considered an orientational background art.
Therefore, none of the stated patents includes design of blood bag valve breaker, which is the subject of this patent application. Disclosure of Invention
The technical problem is successfully solved by the design of a blood bag valve breaker according to this invention.
The process of obtaining blood products from a donor consists of several phases. Following the donation process, the blood in the main bag of the system is centrifuged for a certain time and at a certain speed, and by this the blood products are separated to red blood cells, platelets, plasma etc. Since they have different density and specific weight the products in the main bag are stratified into several layers. Following this, a separation of the products into separate containers-bags is performed using manual or automatic presses. In order to make this possible, it is necessary to break the check valve on the main bag.
The design of the blood bag valve breaker according to this patent application is made in such a manner that the output shaft of the driving electromotor is coupled with the excenter of the excenter-lever mechanism. The coupling of this mechanism is connected to the push rod, to which a fork for reception and breaking the valve on the blood bag is connected. The described mechanism is an integral part of the device for centrifugal separation of blood, whose design is a subject of another patent solution.
Brief Description of Drawings
The invention is described in detail by the drawing in which:
Figure 1 - Displays a block scheme of the blood bag valvei'breaker;
Figure 2 - Displays an axonometric view of the excenter-lever mechanism
assembly of the device according to figure 1;
Figure 3 - Displays a horizontal projection of the assembly shown in Fig. 2.; Figure 4 - Displays a lateral projection of the assembly shown in Fig. 2.;
Figure 5 - Displays an axonometric view of the details of the fork of the device in Fig. 2. and,
Figure 6 - Displays an axonometric view of the details of the excenter-lever mechanism with the fork in Fig. 2; Detailed Description of the Invention
According to the attached drawings (Fig. 1-6) the design of the blood bag valve breaker is made in such a manner that the output shaft of the electromotor 1 is coupled with the excenter 2 of the excenter-lever mechanism, which have their bearing in the housing K. The connecting lever 3, of the excenter-lever mechanism, is on one end rotationally connected to the excenter 2, and on the other end to the push rod 4. On the push rod 4, the fork 5 is attached, which moves together with the push rod 4 to the left and to the right for about 30-40°. In the mentioned case the optimum movement is about 30°, but it may be adjusted as needed. Below the movable fork 5, on the housing K, a feed fork 6 for reception and retaining the valve 83 is placed. Beneath the fork 6 spikes 7 for holding the bag 8 are placed. Onto the spikes 7, the positioning openings 82 are slipped, which are constructed on the reinforcement 81 of the bag 8. Between the forks 5, 6 the valve 83 of the bag 8 is placed in such a manner that the rotation axis of the fork 5 is positioned, approximately in the axis of the fork 6, that is in the centre of the valve 83. If necessary, and depending on the position of the valve 83, or the type of the bag 8, the axis of rotation may be adjusted. Opening and breaking the valve 83 occurs after the completed centrifugation process, in such a manner that the activation of the electromotor 1 activates the excenter-lever mechanism, rotating the fork 5 for about 30° left-right-left, resulting in breaking the valve 83. In this manner the path for the separates in the bag 8 becomes open. The number of rotations of the electromotor 1 is also set according to the needs and requirements.
On the outer sides of their arms the movable fork 5 and the fixed fork 6 have built-in screws 51, 61 for adjustment, which through springs, not shown in the drawings, press the balls 52, 62 for reception of the valve 83. Industrial Applicability
The described invention is intended for pilot installation into newly produced devices for blood separation, as well as for installation, as a modular part into already existing devices. It may be positioned into several positions on the device itself. This may be a position on the place of the blood bag, on the place of the separations bags, on the place of the red blood cells bag and on the place of an empty bag.
The described device may be adjusted for installment into all existing blood separators, at any position. This is because the bag systems may be divided by blood separation type into two groups, into Top-Top (TT) and Top-Bottom (TB). Depending on the total number of bags, both systems may be two-system, three- system, four-system, and rarely five-system. The TT bags are specific because all their tubes are placed only on the upper side, while on the TB bags one tube is mandatorily attached to the bottom side.
Depending on the type of the bag and the system, and the requirements set, an appropriate number of (modules) devices are applied.
