[0002] During surgical treatment, wound cleaning, etc., the patient's treatment area will produce blood, pus, effusion and other fluids or other secretions. These fluids need to be cleaned in time to avoid interfering with the treatment process.

[0003] In the prior art, a professional aspirator is used to collect the liquid. The aspirator head is close to the liquid, and the liquid is sucked under the action of negative pressure.

[0004] In the prior art, a plurality of through holes for sucking liquid are provided at the suction head of the suction device, such as a suction head structure of a suction device with publication number CN206508306U.

[0005] The through hole in the prior art is generally located on the side or one end of the suction head. When a small amount of liquid adheres to the surface of the patient's body tissue, if it is directly sucked through the through hole, it is very easy to cause the human tissue to be sucked into the through hole, thereby causing injury to the patient. Utility Model Content

[0006] In view of the shortcomings of the prior art, the utility model provides a suction head of an aspirator, which is more convenient by gathering a small amount of liquid attached to the surface of body tissue and then absorbing it centrally. At the same time, during the absorption process, the suction hole is not facing the body tissue, so the body tissue will not be sucked into the suction hole, thus avoiding damage caused by this, and can effectively solve the problems in the background technology.

[0007] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: an aspirator suction head, comprising a primary tube, one end of which is provided with a negative pressure assembly, the negative pressure assembly comprising a hollow pressure plate fixedly arranged at one end of the primary tube, the one end of the primary tube being in communication with the interior of the hollow pressure plate;

The suction holes are arranged on the inner side of the rubber drainage ring, and the cross-section of the rubber drainage ring is a right triangle. The rubber drainage ring has a drainage function and can gather liquid at the suction holes.

[0009] Furthermore, two symmetrical connecting arms are fixedly provided at the outer end of the primary tube, a connecting hose is fixedly provided at the other end of the primary tube, a secondary tube is fixedly provided at one end of the connecting hose, and the connecting hose serves to connect the primary tube and the secondary tube.

[0010] Furthermore, two symmetrical mounting rods are fixedly provided at the outer end of the secondary tube, one end of the two mounting rods respectively passes through two connecting arms, and the connecting arms can rotate with the mounting rods as axes;

[0011] A baffle plate fixed to the outer end of the mounting rod is provided on the side of the connecting arm facing the diode, and a fastening nut is provided on the side of the connecting arm away from the diode. The fastening nut is threadedly sleeved on the outer end of the mounting rod. After tightening the fastening nut, the connecting arm can be clamped between the baffle plate and the fastening nut, thereby fixing the position of the connecting arm.

[0012] Furthermore, a rubber handle is fixedly provided at the outer end of the secondary tube, a negative pressure hose with a valve is fixedly provided at one end of the secondary tube away from the primary tube, and one end of the negative pressure hose is connected to the main body of the suction device, so that the suction head has suction force.

[0013] Furthermore, an annular cabin is fixedly provided at the outer end of the first-level tube, and a plurality of water inlet holes are opened at the outer end of the first-level tube. The water inlet holes are located inside the annular cabin and are connected to the inside of the annular cabin. A liquid guiding hose is fixedly provided on the side of the annular cabin away from the negative pressure component.

[0014] Furthermore, a liquid storage cylinder storing pure water is fixedly provided at the outer end of the secondary tube, and one end of the liquid guiding hose extends into the liquid storage cylinder and is fixedly connected to the liquid storage cylinder, so that the absorbed liquid can be diluted with the help of pure water to reduce the resistance during the flow of the liquid;

[0016] Compared with the prior art, the utility model provides a suction head of an aspirator, which has the following beneficial effects:

[0017] By pressing the negative pressure component against body tissue with liquid attached, the part will be sunken downward, and the liquid will gather in the sunken part under the action of gravity, flow to the hollow pressure plate, and finally be absorbed by the suction hole. This method can gather a small amount of liquid attached to the surface of body tissue and absorb it in a concentrated manner, which is more convenient. At the same time, during the absorption process, the suction hole is not facing the body tissue, so the body tissue will not be sucked into the suction hole, thus avoiding damage.

DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] like Figure 1-5 As shown, the utility model provides a suction head of an aspirator, comprising a primary tube 1, one end of the primary tube 1 is provided with a negative pressure assembly 3, the negative pressure assembly 3 comprises a hollow pressure plate 301 fixedly arranged at one end of the primary tube 1, and one end of the primary tube 1 is communicated with the interior of the hollow pressure plate 301;

[0026] The hollow pressure plate 301 is provided with a plurality of suction holes 303 on the side facing the primary tube 1. A rubber drainage ring 302 is fixedly provided on the side facing the primary tube 1. The suction holes 303 are arranged on the inner side of the rubber drainage ring 302. The cross section of the rubber drainage ring 302 is a right triangle. The rubber drainage ring 302 has a drainage function and can gather liquid at the suction holes 303.

[0027] During use, the side of the hollow pressing plate 301 away from the primary tube 1 is pressed against the body tissue with liquid attached. Since the body tissue is generally soft and elastic, when the hollow pressing plate 301 presses the body tissue downward, the part will be concave downward, and the hollow pressing plate 301 is located in the concave part. The liquid attached to the body tissue gathers in the concave part under the action of gravity and flows to the hollow pressing plate 301. A rubber drainage ring 302 is fixed on the hollow pressing plate 301, and the shape of the rubber drainage ring 302 is also concave inwardly. Therefore, the liquid gathered at the hollow pressing plate 301 will be in the rubber drainage ring 302. Under the guidance of the rubber drainage ring 302, the liquid reaches the suction hole 303. Under the action of suction, the liquid is sucked into the hollow pressure plate 301 through the suction hole 303 and is finally sucked away along the primary tube 1. This method of sucking liquid can gather a small amount of liquid attached to the surface of body tissue and absorb it centrally, which is more convenient. At the same time, during the absorption process, the suction hole 303 is not facing the body tissue, so the body tissue will not be sucked into the suction hole 303, thus avoiding damage. This method is suitable for body tissue in soft and tough parts, and is not suitable for tissue parts with poor strength and cannot be pressed.

[0028] During use, the angles of the primary tube 1 and the negative pressure assembly 3 can be adjusted as needed. Figure 1 , 5 As shown, two symmetrical connecting arms 5 are fixedly provided at the outer end of the primary tube 1, a connecting hose 4 is fixedly provided at the other end of the primary tube 1, a secondary tube 11 is fixedly provided at one end of the connecting hose 4, and the connecting hose 4 serves to connect the primary tube 1 and the secondary tube 11.

[0029] Two symmetrical mounting rods 12 are fixedly provided at the outer end of the secondary tube 11. One end of the two mounting rods 12 passes through two connecting arms 5 respectively. The connecting arms 5 can rotate around the mounting rods 12 as axes.

[0030] The side of the connecting arm 5 facing the secondary tube 11 is provided with a baffle 13 fixed to the outer end of the mounting rod 12, and the side of the connecting arm 5 away from the secondary tube 11 is provided with a fastening nut 14, and the fastening nut 14 is threadedly sleeved on the outer end of the mounting rod 12. After tightening the fastening nut 14, the connecting arm 5 can be clamped between the baffle 13 and the fastening nut 14, thereby fixing the position of the connecting arm 5.

[0031] The primary tube 1 and the secondary tube 11 are connected by the connecting hose 4. After loosening the fastening nut 14, the connection arm 5 can be released, so that the connecting arm 5 can rotate around the mounting rod 12 and drive the primary tube 1 and the negative pressure component 3 to rotate, so as to adjust the angle of the negative pressure component 3 to suit different usage scenarios. After the adjustment, tighten the fastening nut 14, and the connecting arm 5 is clamped between the baffle 13 and the fastening nut 14.

[0032] In order to reduce the resistance of the liquid during the absorption process, Figure 1-4 As shown, a rubber handle 7 is fixedly provided at the outer end of the secondary tube 11, and a negative pressure hose 8 with a valve is fixedly provided at one end of the secondary tube 11 away from the primary tube 1. One end of the negative pressure hose 8 is connected to the main body of the suction device, so that the suction head has suction force.

[0033] An annular cabin 2 is fixedly provided at the outer end of the first-level tube 1. A plurality of water inlet holes 9 are opened at the outer end of the first-level tube 1. The water inlet holes 9 are located inside the annular cabin 2 and are connected to the inside of the annular cabin 2. A liquid guide hose 10 is fixedly provided on the side of the annular cabin 2 away from the negative pressure component 3.

[0034] The outer end of the secondary tube 11 is fixedly provided with a liquid storage cylinder 6 storing pure water, and one end of the liquid guiding hose 10 extends into the liquid storage cylinder 6 and is fixedly connected to the liquid storage cylinder 6. The pure water can dilute the absorbed liquid to reduce the resistance during the liquid flow process;

[0035] The outer end of the liquid storage cylinder 6 is provided with a water injection port and a rubber plug is provided at the water injection port. Pure water can be injected into the liquid storage cylinder 6 by opening the rubber plug.

[0036] The liquid storage cylinder 6 is stored with sterilized pure water, and the liquid storage cylinder 6 and the annular cabin 2 are connected by a liquid guiding hose 10. When the liquid secreted from the body is absorbed, suction is also generated at the water inlet 9. Under the action of the suction, the water inside the liquid storage cylinder 6 is sucked into the annular cabin 2 along the liquid guiding hose 10, and finally enters the first-level tube 1 through the water inlet 9. The water can dilute the liquid such as blood and pus entering the first-level tube 1, reduce its viscosity, prevent it from sticking to the inner wall of the first-level tube 1, and make it flow more smoothly.

[0037] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
