Description

Technical Field

[0001] The utility model relates to the field of blood filtration pipelines, in particular to a blood filter machine neck tube which is easy to fix. Background Art

[0002] Hemofiltration is the process of introducing the patient's arterial blood into a semi-permeable membrane filter with good permeability and an area equivalent to the glomerular filtration membrane. Due to the transmembrane pressure gradient between the blood area and the outside of the membrane, when the blood passes through the filter, the plasma, except for formed elements such as proteins and cells, water and most small and medium-molecule substances are filtered out, so as to achieve the therapeutic purpose of clearing excess water and solutes retained in the blood. Some hemofiltration tubes will be inserted through the patient's neck.

[0003] The intrajugular tube needs to be inserted into the patient's neck. Twisting the patient's head will cause the tube to shift or bend, affecting blood filtration and causing discomfort to the person's head.

[0004] Therefore, it is necessary to propose a blood filter neck tube that is easy to fix to solve the above problems. Utility Model Content

At the same time, the two arc clips can slide on the corresponding first semicircular hoop and second semicircular hoop to facilitate personnel to adjust the position.

[0014] 2. Warm water can be input into the input port, and the warm water flows into the inner cavity, and generates heat in the first semicircular hoop and the second semicircular hoop. The heat is transferred to the engaged pipe, so that the liquid or blood passing through is heated to a suitable temperature, thereby avoiding the situation where the blood is cooled through the pipe when the weather is cold. At the same time, the silicone pad can improve the comfort of the first semicircular hoop and the second semicircular hoop when worn on the patient's head. The warm first semicircular hoop and the second semicircular hoop can increase the patient's body temperature and avoid excessive hypothermia. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will be combined with the accompanying drawings in the embodiments of the present invention to clarify the technical solutions in the embodiments of the present invention; it is clear that the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] The utility model provides Figure 1 one Figure 3 The shown embodiment is a blood filter machine neck tube that is easy to fix, comprising a first semicircular hoop 1 and a second semicircular hoop 3. The first semicircular hoop 1 and the second semicircular hoop 3 are both elastic, and are elastically connected to each other. The first semicircular hoop 1 and the second semicircular hoop 3 are combined into a circular shape, and the circular structure is sleeved on the patient's head.

[0021] A fixing plate 2 is fixed at both ends of the first semicircular hoop 1 and the second semicircular hoop 3. An elastic rope 4 is provided between the two corresponding fixing plates 2. A through hole is provided on the fixing plate 2 for the elastic rope 4 to pass through and be knotted.

[0022] In the actual operation of the present invention, the first semicircular hoop 1 and the second semicircular hoop 3 can be put on the patient's head. Since the first semicircular hoop 1 and the second semicircular hoop 3 are elastic themselves, they can adapt to different head shapes. And since the first semicircular hoop 1 and the second semicircular hoop 3 are connected by an elastic rope 4, when the patient's head is larger, the elastic rope 4 is stretched, which can increase the distance between the first semicircular hoop 1 and the second semicircular hoop 3 to adapt to patients with different head radii.

[0023] The top of the first semicircular hoop 1 and the second semicircular hoop 3 are both provided with a sliding groove 5, and the two sliding grooves 5 are slidably fitted with an L-shaped slider 7. An arc-shaped clip 9 is provided on one side of the two L-shaped sliders 7, and a pipe is clamped in the arc-shaped clip 9. Silicone pads 6 are fixed on the inner sides of the first semicircular hoop 1 and the second semicircular hoop 3, and electric heating wires are fixed inside the two L-shaped sliders 7. One end of the pipe is connected to the blood filter machine, and the other end of the pipe is inserted into the patient's neck.

[0024] In the actual operation of the present invention, when the first semicircular hoop 1 and the second semicircular hoop 3 are sleeved on the patient's head, the blood filtration pipe can be fixed to the patient's head through the arc clamp 9 to avoid the pipe from moving and bending during blood filtration. At the same time, the two arc clamps 9 can slide on the corresponding first semicircular hoop 1 and the second semicircular hoop 3, which is convenient for personnel to adjust the position.

[0025] The first semicircular hoop 1 and the second semicircular hoop 3 are both provided with an inner cavity, and the outer side of the first semicircular hoop 1 and the second semicircular hoop 3 are both provided with an input port 11, which is connected to the corresponding inner cavity, and warm water can be input into the input port 11, and the warm water flows into the inner cavity, and generates heat in the first semicircular hoop 1 and the second semicircular hoop 3, and the heat is transferred to the engaged pipe, so that the passing liquid or blood is heated to a suitable temperature, avoiding the situation where the blood is cooled through the pipe when the weather is cold. At the same time, the silicone pad 6 can not only improve the comfort of the first semicircular hoop 1 and the second semicircular hoop 3 when worn on the patient's head, but also the warm first semicircular hoop 1 and the second semicircular hoop 3 can increase the patient's body temperature and avoid excessively low temperature.

[0026] Specifically, the sliding structure of the L-shaped slider 7 is that a slider is fixed on the L-shaped slider 7, and the slider slides in the corresponding sliding groove 5. A fixed block 8 is fixed on one side of the two L-shaped sliders 7, and the arc card 9 is fixed to the corresponding fixed block 8, and the arc card 9 is elastic.
