Description

Technical Field

[0001] The utility model relates to the technical field of endocrine effusion extraction, in particular to an effusion extraction device. Background Art

[0002] The Endocrinology Department is a place in the hospital that specializes in the treatment of endocrine diseases. It is mainly responsible for the clinical diagnosis and treatment of diabetes, obesity, osteoporosis, gout, lipid metabolism disorders, and diseases of the thyroid, pituitary, adrenal glands, gonads, parathyroid glands, etc. Endocrine disorders can cause various discomforts in the human body and can also cause many diseases and hazards, such as: skin deterioration, many women have had such experiences, many yellow spots and pigmentation suddenly appeared on their beautiful faces, and a lot of cosmetics did not help. In fact, this is not just a skin problem, these pigmentation spots are also caused by adverse stimulation from external factors when the endocrine is unstable. Patients with endocrine disorders will have fluid accumulation in their bodies, which cannot be automatically discharged from the body and need to be discharged with the help of fluid extraction equipment.

[0003] After searching, the patent with announcement number CN213048454U discloses a device for extracting effusion in the endocrinology department, including an extraction tube, the left side of the extraction tube is connected to a liquid extraction tube, the left end of the liquid extraction tube is fixedly installed with a needle tube, the bottom of the liquid extraction tube is fixedly installed with a fixed block, the top of the fixed block is provided with a liquid outlet, the liquid outlet is connected to the liquid extraction tube, a sealing gasket arranged obliquely is fixedly installed below the inner cavity of the liquid outlet, and a liquid storage bottle is installed with internal threads of the fixed block. The utility model can prevent the effusion from seeping out of the connection when the effusion is extracted by making the upper end of the liquid storage bottle contact with the sealing gasket, and the liquid storage bottle is easy to install and disassemble, and the control valve at the top of the extraction tube can be closed when the liquid storage bottle is almost full to prevent the internal effusion from flowing back, and at the same time solves the problem that once the device is tilted during use, the effusion is easy to leak out from the bottle mouth, which not only affects the collection of the effusion, but also causes the effusion to flow back.

[0004] The technical solution has the following problems:

[0005] In the process of extracting the effusion, it is necessary to pull the push rod with one hand and hold the fixed handle with the other hand to extract the effusion into the storage bottle. When the doctor needs to extract with one hand, it is not convenient for the medical staff to extract the effusion into the storage bottle with one hand, which is quite inconvenient. At the same time, if the medical staff fails to hold the extraction tube and accidentally drops it on the ground, when the needle tube contacts the ground, the whole thing can only be replaced, which increases the cost. Utility Model Content

[0006] The purpose of the utility model is to solve the problem in the prior art that in the process of extracting the accumulated fluid, it is necessary to pull the push rod with one hand and hold the fixed handle with the other hand to extract the accumulated fluid into the liquid storage bottle. When the doctor needs to extract the fluid with one hand, it is inconvenient for the medical staff to extract the accumulated fluid into the liquid storage bottle with one hand, which is quite inconvenient. At the same time, if the medical staff fails to hold the extraction tube and accidentally drops it on the ground, when the needle tube contacts the ground, the whole thing can only be replaced, which increases the cost disadvantage. Therefore, a fluid extraction device is proposed.

[0014] In a possible design, one side of the push handle and one side of the handle are both provided with anti-skid grooves for increasing hand friction and preventing slipping.

[0015] In a possible design, the extraction tube and the liquid storage bottle are both made of medical transparent PP material.

[0016] In the present application, when in use, the medical staff clamps the index finger and the middle finger on both sides of the extraction tube and fits one side of the handle, and then places the thumb on the push handle. If the extraction tube accidentally falls on the ground and the needle contacts the ground, the cover body can be opened, and the spare needle in the placement box can be taken out and installed on the extraction tube through a threaded connection. The spare needle and the placement box can be used as a spare when the needle falls on the ground, and there is no need to disassemble the unopened extraction tube as a whole, which saves costs. Then the push handle is pushed, and the movement of the push handle drives the movement of the push rod, and also drives the telescopic rod to be extended and retracted. During the movement of the push handle, the spring is compressed. The movement of the push rod drives the movement of the piston, and then the needle is inserted into the position where the patient needs to extract the accumulated fluid, and then the thumb pushing the push handle is released. At this time, the force of the spring is released, and the push handle is pushed by the force of the spring to drive the push rod and the piston to rebound. The movement of the piston generates suction, and the accumulated fluid is extracted into the extraction tube through the needle, and then transported to the liquid storage bottle through the installation tube to store the accumulated fluid, completing one-handed extraction. The inner wall of the sealing cover is provided with an internal thread, which can be connected to the extraction tube thread. When not in use, one end of the extraction tube can be closed to prevent dust from entering. Two spare needles (or needles and spare needles) can be placed in the storage box.

[0017] In the utility model, the device for extracting effusion is described. Through the rebound mechanism, the medical staff clamps the index finger and the middle finger on both sides of the extraction tube and fits one side of the handle. Then, the thumb is placed on the push handle and the push handle is pushed. The movement of the push handle drives the movement of the push rod and also drives the telescopic rod to be extended and retracted. During the movement of the push handle, the spring is compressed. The movement of the push rod drives the movement of the piston. Then, the needle is inserted into the position where the patient needs to extract the effusion. Then, the thumb pushing the push handle is released. At this time, the force of the spring is released. The push handle is pushed by the force of the spring to drive the push rod and the piston to rebound. The movement of the piston generates suction. The effusion is extracted into the extraction tube through the needle and then transported to the liquid storage bottle through the installation tube. The effusion is stored, which is convenient for the doctor to complete the extraction with one hand.

[0018] In the utility model, the device for extracting effusion has a backup mechanism. If the extraction tube accidentally falls on the ground and the needle contacts the ground, the cover can be opened to take out the backup needle in the placement box and install the backup needle on the extraction tube through a threaded connection. The backup needle and the placement box can be used as a backup when the needle falls on the ground, without the need to additionally disassemble the unopened extraction tube as a whole, thus saving costs.

[0019] The utility model has a reasonable structure. The rebound mechanism can facilitate single-handed extraction by medical personnel. The spare mechanism can be used as a spare when the needle falls on the ground. There is no need to disassemble the unopened extraction tube as a whole, thus saving costs.
