Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment, specifically to a device for evenly applying burn ointment. Background Technology

[0002] Burns are a common clinical condition, typically caused by heat (such as hot liquids, steam, high-temperature gases, flames, molten metal, etc.) that damages tissue, primarily affecting the skin and mucous membranes. In severe cases, it can damage subcutaneous tissues such as muscles, joints, and even internal organs. Currently, when applying ointments after a burn, existing ointment application devices dispense a loose, semi-solid paste, which cannot adequately cover the burn. To spread the ointment evenly, tools like cotton swabs are needed, which inevitably irritate the burn and cause additional pain. There is a lack of an application device that can evenly spread the ointment on the burn upon application. Utility Model Content

[0003] The purpose of this invention is to address the above-mentioned shortcomings by providing a device for evenly applying burn ointment.

[0004] This utility model includes a syringe and an extrusion head.

[0005] The extrusion head is trapezoidal and is installed at the outlet end of the syringe. A set of fan-shaped flow dividers is provided inside the extrusion head. An annular grip is provided on the lower outer wall of the syringe, and multiple sets of anti-slip grooves are provided on the annular grip.

[0006] The syringe has an elliptical outlet. The extrusion head consists of a connecting sleeve, a central tube, a pair of branch tubes, and a die. The bottom of the connecting sleeve has three outlet holes. The inlet ends of the central tube and the pair of branch tubes are connected to the corresponding outlet holes. The top of the die has three inlet holes. The outlet ends of the central tube and the pair of branch tubes are connected to the corresponding inlet holes. The connecting sleeve is fitted onto the syringe outlet.

[0007] The cross-section of the die head is an isosceles trapezoid, and the bottom of the die head is the drug outlet.

[0008] Each inlet hole of the die head is equipped with a pair of fan-shaped diverter plates at the bottom.

[0009] A pair of fan-shaped diverter plates are arranged in a figure-eight pattern.

[0010] The inlet end of the extruder is cylindrical, and the outlet end of the extruder has an elliptical cross-section.

[0011] A set of fan-shaped manifolds are installed inside the extruder in a fan-shaped distribution.

[0012] The syringe has an external thread on the outer wall of the outlet end and an internal thread on the inner wall of the inlet end of the extrusion head. The extrusion head is threadedly installed at the outlet end of the syringe.

[0013] The outlet end of the extruder is equipped with a latex sealing cap with an elliptical cross-section.

[0014] The advantages of this invention are: during extrusion, the ointment is shaped into a wider ointment surface through the die head, so that the ointment can be evenly covered on the patient's burn area. Attached Figure Description

[0025] As shown in the attached diagram, this utility model includes a syringe 1 and an extrusion head 2.

[0026] The extrusion head 2 is trapezoidal and is installed at the outlet end of the syringe 1. A set of fan-shaped flow dividers 3 are provided inside the extrusion head 2. An annular grip part 4 is provided on the lower outer wall of the syringe 1. Multiple anti-slip grooves are provided on the annular grip part 4.

[0027] The syringe 1 has an elliptical outlet. The extrusion head 2 consists of a connecting sleeve 5, a central tube 6, a pair of branch tubes 7, and a die head 8. The bottom of the connecting sleeve 5 has three outlet holes. The inlet ends of the central tube 6 and the pair of branch tubes 7 are connected to the corresponding outlet holes. The top of the die head 8 has three inlet holes. The outlet ends of the central tube 6 and the pair of branch tubes 7 are connected to the corresponding inlet holes. The connecting sleeve 5 is fitted onto the outlet of the syringe 1.

[0028] The cross-section of the die head 8 is an isosceles trapezoid, and the bottom of the die head 8 is the drug outlet.

[0029] Each inlet hole of the die head 8 is equipped with a pair of fan-shaped diverter plates 3 at the bottom.

[0030] A pair of fan-shaped diverter plates 3 are distributed in a figure-eight shape.

[0031] The inlet end of the extruder 2 is cylindrical, and the outlet end of the extruder 2 has an elliptical cross-section.

[0032] A set of fan-shaped flow dividers 3 are installed in the extruder head 2 in a fan-shaped distribution.

[0033] The syringe 1 has an external thread on the outer wall of its outlet end and an internal thread on the inner wall of its inlet end. The extrusion head 2 is threadedly installed at the outlet end of the syringe 1.

[0034] The outlet end of the extruder 2 is provided with a latex sealing cap 9 with an elliptical cross-section. After use, the outlet end of the extruder 2 can be temporarily sealed by the latex sealing cap 9.

[0035] Example 1: As shown in the attached document Figure 1-3 As shown, the medication application device can be used with one hand or two hands. When used with one hand, like a standard syringe, the thumb presses the syringe piston to squeeze out the ointment. When used with two hands, one hand holds the annular grip 4 at the bottom of the syringe barrel, and the other hand presses down on the syringe piston to squeeze out the ointment. The syringe piston forces the ointment into the connecting sleeve 5, which then flows through the central tube 6 and a pair of branch tubes 7 to the mandrel 8. After passing through a pair of fan-shaped diverter plates 3, the ointment flows out evenly from the outlet end of the mandrel 8 and is spread evenly on the patient's burn area. The mandrel 8 in this design is wider, allowing for a larger application area.

[0036] Example 2: As shown in the attached document Figure 4 and attached Figure 5 As shown, the medication application device can be used with one hand or two hands. When used with one hand, like a standard syringe, the thumb presses the syringe piston to squeeze out the ointment. When used with two hands, one hand holds the annular grip 4 at the bottom of the syringe barrel, and the other hand presses down on the syringe piston to squeeze out the ointment. The syringe piston forces the ointment into the extrusion head 2, where a set of fan-shaped diverter plates 3 guides the input ointment, ensuring it flows evenly from the outlet end of the extrusion head 2 and spreads evenly on the patient's burn area. The extrusion head 2 in this design is relatively narrow, but the structure is simple.
