Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a hemodialysis bubble removing device and a dialysis device thereof.
Background
Hemodialysis equipment includes dialyzers, hemofilters, hemoperfusion apparatus, endotoxin filters, etc. Wherein, the dialyzer usually comprises a bundle of hollow fiber semipermeable membranes and an external cylindrical container, blood flows into the hollow fiber membranes from one side of the cylindrical container during dialysis, dialysate flows out of the hollow fiber membranes from the other direction, and toxins and small molecular impurities in the blood diffuse into the dialysate through the semipermeable membranes to realize the purification of the blood. The structure of the hemofilter is basically the same as that of the dialyzer, but the material and the pore diameter of the hollow fiber semipermeable membrane are different, so that the hemofilter can achieve the blood purification effect different from that of the dialyzer. The endotoxin filter and the dialyzer are similar in structure and also consist of a plurality of hollow fiber semipermeable membranes, and are generally arranged before dialysis water enters the dialyzer to further purify the dialysis water, particularly the water for blood filtration fluid replacement. The hemoperfusion device is usually a cylindrical container with openings at two ends, and is filled with adsorption resin and preservation solution, and can be used independently or used together with a dialyzer after the hemoperfusion device is connected in series with the dialyzer.
Before dialysis begins, a dialyzer and a dialysis pipeline need to be connected, physiological saline is used for pre-charging the whole pipeline, during pre-charging, the blood perfusion device, the dialyzer, the blood filter and the endotoxin filter need to ensure that a pre-charging amount is sufficient, and the pipelines, the blood perfusion device, the dialyzer, the blood filter and the endotoxin filter are full of saline and free of bubbles so as to prevent possible coagulation and bubbles from entering blood. During the dialysis, the infusion is also guaranteed to be bubble-free.
However, the flow of liquid in the hemodialysis apparatus mainly depends on the external water pressure to make the liquid in the pipeline flow, so as to realize the liquid transportation and the liquid supplementation in the dialysis process, and the external water pressure can only realize the stress in the liquid flow direction, and cannot give the acting force in the direction perpendicular to the liquid flow direction, which results in the following consequences: liquid is not sufficiently fed into partial spaces of the dialyzer, the blood filter, the blood perfusion device and the endotoxin filter, and bubbles are easy to appear. Air bubbles, when present in the endotoxin filter, can cause a dialysis device to give a false alarm during self-testing; when air bubbles are present in the dialyzer or hemofilter, coagulation phenomena are initiated; when air bubbles exist in the blood perfusion device, the resin in the blood perfusion device is difficult to be effectively washed by normal saline and difficult to be effectively adsorbed by the resin. In addition, the existence of the air bubbles also increases the priming quantity, prolongs the priming time, consumes more priming saline water and discharges the air bubbles.
In order to ensure that no bubbles remain, the operator can manually beat and beat the pipelines, the dialyzer, the blood filter, the blood perfusion device and the endotoxin filter to remove the bubbles, but the mode has low efficiency and the bubbles existing everywhere are difficult to detect.

Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
As shown in fig. 1 to 7, an embodiment of the present invention provides a hemodialysis bubble remover, including: a clamping mechanism 1 and a transverse vibration mechanism 2.
The holding means 1 is adapted to hold a housing of one or more of a hemoperfusion cartridge, a dialyzer, a blood filter, an endotoxin filter. The clamping mechanism 1 is clamped on one or more of the housings of the hemoperfusion apparatus, the dialyzer, the blood filter and the endotoxin filter, and means that the hemodialysis bubble removing device can be clamped on any one of the housings of the hemoperfusion apparatus, the dialyzer, the blood filter and the endotoxin filter by the clamping mechanism 1, and two or more than two hemodialysis bubble removing devices can be arranged, so that the hemodialysis bubble removing device is suitable for any combination of the hemoperfusion apparatus, the dialyzer, the blood filter and the endotoxin filter.
The transverse vibration mechanism 2 is arranged on the clamping mechanism 1, is suitable for conducting vibration to the clamping mechanism 1, and has a vibration direction parallel to a plane where the clamping mechanism 1 is located.
When the clamping objects of the clamping mechanism 1 are used for clamping the blood perfusion device, the dialyzer, the blood filter and the endotoxin filter, the plane where the clamping mechanism 1 is located in the middle of the blood perfusion device, the dialyzer, the blood filter and the endotoxin filter and is perpendicular to the vertical direction formed by the top ends and the bottom ends of the blood perfusion device, the dialyzer, the blood filter and the endotoxin filter, namely the plane where the clamping mechanism 1 is located is the horizontal direction. The vibration direction of the transverse vibration mechanism 2 is parallel to the plane of the clamping mechanism 1, so that transverse vibration can be transmitted to the blood perfusion device, the dialyzer, the blood filter and the endotoxin filter which are clamped by the clamping mechanism 1. Because the vibration has an attenuation effect on the resistance caused by surface tension and yield stress, and can also reduce the pressure difference between two ends for pushing the liquid to move, the vibration can promote the floating and the discharge of the bubbles in the hemoperfusion device, the dialyzer, the hemofilter and the endotoxin filter, but new bubbles are formed if the liquid is separated from the liquid level during the vibration. The hemodialysis bubble remover transmits the vibration parallel to the plane of the clamping mechanism 1 to the hemoperfusion device, the dialyzer, the blood filter and the endotoxin filter clamped by the clamping mechanism 1 through the transverse vibration mechanism 2, so that the vibration in the vertical direction of the hemoperfusion device, the dialyzer, the blood filter and the endotoxin filter is avoided, the floating and the discharge of bubbles are promoted, and meanwhile, the surface layers of the hemoperfusion device, the dialyzer, the blood filter and the endotoxin filter, especially the liquid in the vertical direction is prevented from separating from the liquid level to form new bubbles under the action of vibration.
The blood perfusion device comprises adsorptive resin particles, injected physiological saline and heparin, and the transverse vibration mechanism vibrates to enhance the collision of the resin particles in the blood perfusion device so as to separate the resin particles from the adsorbed bubbles and further promote the discharge of the bubbles. The fine tube-shaped container can promote the floating and discharge of air bubbles in the dialyzer, blood filter and endotoxin filter with a hollow fiber structure.
For achieving the object of the present invention, the design manner of the clamping mechanism is not exclusive, and in this embodiment, a preferred implementation manner is provided, where the clamping mechanism 1 includes:
the clamping section 11 is composed of a long arm 111 and a short arm 112; the long arm 111 and the short arm 112 are suitable for being buckled to form a space for clamping the shell;
the rotating shaft 12 is arranged at the end parts of the long arm 111 and the short arm 112, and is suitable for rotatably connecting the long arm 111 and the short arm 112;
a handle segment 13, the handle segment 13 being composed of a first handle segment 131 and a second handle segment 132; the first handle segment 131 is connected with the end of the long arm 111; the second handle segment 132 is attached to the end of the short arm 112; the first handle segment 131 and the second handle segment 132 take the rotating shaft 12 as an intersecting axis and form an included angle;
a spring 14, wherein the spring 14 is disposed at an included angle between the first handle section 131 and the second handle section 132.
In order to increase the contact area between the clamping mechanism 1 and the shells of the hemoperfusion apparatus, the dialyzer, the blood filter and the endotoxin filter, the long arm 111 is arc-shaped, and the center of the circle is positioned in a clamping space formed by buckling the long arm 111 and the short arm 112; the short arm 112 is arc-shaped, and the center of the circle is located outside the clamping space formed by buckling the long arm 111 and the short arm 112.
In this embodiment, the long arm 111 is an arc with a central angle of 240 degrees and 210 degrees, so as to ensure a larger contact area with the clamped object; the short arm 112 is a minor arc, and the center of the arc is a reverse arc and is clamped towards the inner side of the clamping space. Due to the structural design, the long arm 111 and the cylindrical shell of the hemoperfusion device, the dialyzer, the blood filter and the endotoxin filter have larger contact area, the larger contact area can achieve better vibration defoaming effect, and more stable clamping can be achieved.
In order to ensure the stable clamping of the clamping mechanism 1 and the shells of the hemoperfusion device, the dialyzer, the blood filter and the endotoxin filter, the inner sides of the long arm 111 and the short arm 112 are provided with anti-skid layers. As an alternative design manner of this embodiment, the inner sides of the long arm 111 and the short arm 112 may further be provided with a toothed texture.
In order to facilitate the installation of the hemodialysis bubble removing device, a fixing clamp ring 15 is further arranged on the handle section 13, and the fixing clamp ring 15 is suitable for fixing the clamping mechanism 1. The hemodialysis bubble remover can be clamped on dialysis equipment through the fixing clamping ring 15.
In order to reduce the vibration influence of the hemodialysis bubble trap on the dialysis equipment, the inner side of the fixing snap ring 15 can be further provided with a shock absorption pad.
For the purpose of the present invention, the design manner of the transverse vibration mechanism 2 is not unique, and in the present embodiment, a preferable implementation manner is provided, where the transverse vibration mechanism 2 includes:
a housing 21, wherein the housing 21 is fixed on the long arm 111;
a vibrator 22, the vibrator 22 being provided in the case 21 and adapted to conduct vibration to the case 21;
the magnet 23 is arranged in the vibrator 22, and the magnetic pole direction of the magnet 23 is parallel to the plane of the clamping mechanism 1;
a coil 24, the position of the coil 24 being opposite to the position of the magnet 23.
In order to realize larger contact area and more uniform vibration conduction, the housing 21 is arc-shaped, and comprises an upper cover 211, a lower cover 212, an outer shell 213, an inner shell 214, a first end cover 215 and a second end cover 216, which form a hexahedron with a containing space; the inner shell 214 is fixed on the long arm 111 through an arc-shaped slot 25 and is attached to the long arm 111. That is, the upper cover 211, the lower cover 212, the outer shell 213, and the inner shell 214 are all arc-shaped, and the structure design is such that the contact between the lateral vibration mechanism 2 and the clamping mechanism 1 is surface contact, not point contact, and thus, vibration is more sufficiently transmitted to the long arm 111, and vibration loss is reduced.
As a specific design manner of this embodiment, the hemodialysis bubble remover further includes a first inner plate 217 and a second inner plate 218; the first inner plate 217 and the second inner plate 218 are provided in the case 21, and are adapted to form a space for accommodating the vibrator 22. In this embodiment, the first inner plate 217 and the second inner plate 218 are arc-shaped and correspond to an arc surface of the housing 21. This structure allows the vibrator 22 in the case 21 to be separated from the coil 24 and the like.
In order to fix the vibration direction of the hemodialysis bubble remover, the hemodialysis bubble remover also comprises a moving shaft 26; one end of the moving shaft 26 is fixed to the outer case 213, and the other end thereof is fixed to the inner case 214 and penetrates the vibrator 22. The 9-structured design is such that the moving shaft 26 is parallel to the plane of the clamping mechanism 1, the vibrator 22 vibrates along the moving shaft 26, and the ends of the moving shaft 26 are fixed to the outer case 213 and the inner case 214, respectively, so that the lateral vibration can be transmitted to the outer case 213 and the inner case 214, and further to the long arm 111 attached to the inner case 214, and transmitted to the clamped object in the clamping mechanism 1.
As a preferable scheme of the present embodiment, the vibrator 22 is provided with a long hole 221, the long hole 221 is adapted to pass through the moving shaft 26, and an extending direction of the long hole 221 is perpendicular to the moving shaft 26. The long hole 221 is disposed such that the vibrator 22 can move not only along the movement axis 26 but also along the extending direction of the long hole 221, so that the vibrator 22 can realize vibration in two directions on a horizontal plane. The vibration in two directions enables the vibrator 22 to have larger amplitude in the plane direction parallel to the clamping mechanism 1, so that a better vibration defoaming effect is achieved under the condition that liquid in the vertical direction is not separated from the liquid level to form new bubbles.
The material of the vibrator 22 is not exclusive, and in order to achieve a good vibration effect, the vibrator 22 may be made of a material having elasticity, for example, hard rubber, and those skilled in the art may select the material according to actual conditions.
In order to ensure better uniformity of vibration amplitude at each position of the long arm 111, the vibrator 22 of the transverse vibration mechanism 2 is arc-shaped and corresponds to the first inner plate 217 and the second inner plate 218; the three magnets 23 are arranged in the vibrator 22 at equal intervals; coils 24 are provided on both sides of each of the magnets 23. With this structure, the vibrator 22 can vibrate at three positions.
For the convenience of installation, the coils 24 on both sides of the magnet 23 are respectively installed between the first inner plate 217 and the outer case 213 and between the second inner plate 218 and the inner case 214.
As a specific design manner of the present embodiment, the coil 24 is mounted in the housing 21 through a mounting rod 27; one end of the mounting rod 27 is fixed to the upper cover 211, and the other end is fixed to the lower cover 212.
In order not to affect the vibration conduction of the moving shaft 26, the mounting rod 27 is provided with an annular hole 28; the annular hole 28 is adapted to pass the moving shaft 26. The hole area of the annular hole 28 is larger than the cross-sectional area of the moving shaft 26, so that the moving shaft 26 does not contact the mounting rod 27 even under vibration, thereby ensuring that the upper cover 211 and the lower cover 212 connected with the mounting rod 27 are not affected by vibration and avoiding the generation of vibration in the vertical direction.
In order to increase the contact area between the vibrator 22 and the second inner plate 218 during vibration, three arc surface sections, namely a first arc surface section 222, a second arc surface section 223 and a third arc surface section 224, are arranged on the surface, attached to the second inner plate 218, of the vibrator 22. As a preferred implementation manner of the present embodiment, when the central angle of the arc shape of the housing 21 is 240 °, as shown in fig. 8, and the direction of the arrow c shown in fig. 8 is 0 °, the three arc surface segments are respectively within three angular ranges of (-30 °, 30 °), (60 °, 120 °), and (150 °, 210 °), and there are three corresponding arc lines having a central angle of 60 ° and an arc shape identical to that of the second inner plate 218. When the central angle of the arc shape of the housing 21 is smaller than 240 °, the angular ranges of the first arc surface segment 222 and the third arc surface segment 224 may be reduced.
The working principle of the transverse vibration mechanism 2 is as follows: the coil 24 is energized to generate an alternating magnetic field, so that the magnet 23 in the vibrator 22 reciprocates under the action of the magnetic field to generate vibration, and the vibration is transmitted to the outer shell 213 and the inner shell 214 of the housing 21. The control of the energization of the coil 24 can be carried out by a person skilled in the art, depending on the actual situation, using conventional control circuits of the prior art.
Taking fig. 4 as an example, the coil 24 between the first inner plate 217 and the outer case 213 is energized to generate an N-pole on the side close to the magnet 23, the coil 24 between the second inner plate 218 and the inner case 214 is energized to generate an S-pole on the side close to the magnet 23, and the magnet 23 is moved to the coil 24 on one side by the magnetic field; the direction of the current is changed so that the coil 24 between the first inner plate 217 and the outer case 213 generates an S-pole on the side close to the magnet 23, the coil 24 between the second inner plate 218 and the inner case 214 generates an N-pole on the side close to the magnet 23, and the magnet 23 moves toward the coil 24 on the other side by the magnetic field, and the cycle is repeated, thereby vibrating the magnet 23.
The application method of the hemodialysis bubble remover in the embodiment is as follows: taking the blood perfusion apparatus as an example, the clamping mechanism 1 is clamped on the shell of the blood perfusion apparatus, so that the vibration of the transverse vibration mechanism 2 is transmitted to the blood perfusion apparatus, and further, the air bubbles in the blood perfusion apparatus are discharged.
