[0021] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0023] In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, "multiple" means two or more, unless otherwise clearly and specifically defined. In addition, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0024] Example 1

[0025] like Figure 1 , Figure 2 and Figure 4 As shown, the utility model provides a tonsil bloodletting device, which is inserted into the oral cavity of a patient when the tonsils are inflamed to bleed the tonsils. The structure includes a needle tube 1 and a push rod 2 that cooperate with each other. The push rod 2 is located at one end of the needle tube 1 and is fixedly mounted with a piston 4 and a needle body. The piston 4 is arranged at the connection between the push rod 2 and the needle body. The axes of the push rod 2 and the needle body coincide with each other. The outer diameter of the needle body is smaller than the inner diameter of the outlet of the needle tube 1, so that the needle body hidden in the needle tube 1 can extend out of the needle tube 1 through the outlet end of the needle tube 1.

[0026] The needle body includes a connecting rod 5 and a puncture needle 6 fixed in the connecting rod 5. The connecting rod 5 is fixedly mounted on the push rod 2. In this embodiment, the connecting rod 5 and the push rod 2 can be arranged as an integrally formed structure.

[0027] The needle tube 1 is made of a transparent material, and an indicator scale is provided on the outer wall of the needle tube 1 along its axial direction, which is convenient for observing the push-out length of the needle body and accurately controlling the insertion depth of the needle during use.

[0028] A handle 3 is symmetrically arranged on the outer wall of the needle tube 1, and a wavy profile that fits the finger joints is arranged on one side of the handle 3 facing the outlet end of the needle tube, thereby improving the stability when holding the bloodletter.

[0029] An annular liquid-stopping ring 7 made of rubber material is provided on the inner wall of the outlet end of the needle tube 1. The annular liquid-stopping ring 7 can prevent blood or oral mucus from entering the needle tube 1 on the one hand, and can drain blood and mucus on the puncture needle 6 when the puncture needle 6 retracts on the other hand.

[0030] Example 2

[0031] like Figure 3 As shown, compared with Example 1, the technical feature of this embodiment is that a return spring abutting against the piston 4 is provided inside the needle tube 1, so that the needle body can be automatically retracted to prevent the oral mucosa from being punctured.

[0032] Example 3

[0033] Comparing this embodiment with Embodiment 1 and Embodiment 2, the distinguishing technical features are: the connecting rod 5 and the push rod 2 are connected by threads, the end of the connecting rod 5 is provided with an external thread, and the end of the push rod is provided with a threaded groove, and the needle body can be disassembled and replaced by twisting the connecting rod.

[0034] In the technical solution, the needle body is fixedly installed on the end of the push rod 2 so that the needle body is hidden in the needle tube 1 when in use. The needle body is moved out of the needle tube 1 by pressing the push rod 2 to bleed the tonsils. The needle body of the improved bloodletting device can be hidden, which can alleviate the patient's resistance to seeing the needle tip.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
