Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical supplies, in particular to a nasopharyngeal hemostatic cotton swab with a sleeve. Background Art
[0002] In clinical practice, nasal endoscopy has become one of the most valuable and advantageous examination methods for observing nasopharyngeal lesions because of its clear images, strong brightness, ability to guide instrument operation, and accurate biopsy positioning.
[0003] The nasopharyngeal mucosa is rich in blood supply and is prone to bleeding after biopsy. Currently, cotton swabs are routinely used in clinical practice to stop bleeding. The surface of the cotton swab is rough, and the friction with the nasal septum when passing through the nasal cavity causes obvious pain to the patient. In addition, because the nasal passage is narrow, only cotton swabs with small heads can enter the nasopharynx. The diameter of the cotton head is 4-5mm, which often cannot cover the wound surface. Slight movement may cause the pressing position to move, and the pressing hemostasis effect is poor. Therefore, in order to solve the above problems, we propose a nasopharyngeal hemostatic cotton swab with a cannula. Utility Model Content
[0004] 1. Technical issues to be resolved
[0005] In view of the deficiencies in the prior art, the utility model provides a nasopharyngeal hemostatic cotton swab with a cannula to solve the technical problem that due to the narrow nasal passage, only cotton swabs with a small head can enter the nasopharynx, the diameter of the cotton head is 4-5mm, which often cannot cover the wound surface, and the slightest movement may cause the pressing position to move, resulting in poor pressing and hemostatic effect.
[0006] (II) Technical solution

[0020] The embodiment of the present application provides a nasopharyngeal hemostatic cotton swab with a sleeve, which effectively solves the technical problem that due to the narrow nasal passage, only cotton swabs with small heads can enter the nasopharynx, and the diameter of the cotton head is 4-5mm, which often cannot cover the wound surface. The slightest movement may cause the pressing position to move, resulting in poor hemostatic effect.
[0021] Example
[0022] like Figure 1 , Figure 2 , Figure 3 ,and Figure 4 As shown, the technical solution in the embodiment of the present application effectively solves the technical problem that due to the narrow nasal passage, only a cotton swab with a small head can enter the nasopharynx, and the diameter of the cotton head is 4-5mm, which often cannot cover the wound surface. A slight movement may cause the pressing position to move, and the pressing hemostasis effect is poor. The overall idea is based on the following:
[0023] In view of the problems existing in the prior art, the utility model provides a nasopharyngeal hemostatic cotton swab with a sleeve, comprising a cotton swab sleeve 1, the inner wall of the cotton swab sleeve 1 is provided with an elastic rubber ball 2, and the outer side of the elastic rubber ball 2 is wrapped with a cotton wool layer 21; the cotton wool layer 21 is slidably installed on the upper section of the inner wall of the cotton swab sleeve 1; the inner wall of the cotton swab sleeve 1 is provided with a support handle 22; the elastic rubber ball 2 is fixedly installed with the upper end of the support handle 22, and the cotton wool layer 21 is fixedly installed with the upper end of the support handle 22, the elastic rubber ball 2 and the cotton wool layer 21 are pushed out of the cotton swab sleeve 1, and the compressed elastic rubber ball 2 after being pushed out is expanded to open the cotton wool layer 21, so that the cotton wool layer 21 and the nasopharynx have a larger compression area, completely covering the nasopharyngeal biopsy wound surface, and achieving a better compression and hemostasis effect.
[0024] The outer side of the cotton swab sleeve 1 is provided with anti-slip grooves 11; the anti-slip grooves 11 are located at the lower section of the outer side wall of the cotton swab sleeve 1; the anti-slip grooves 11 have greater friction to prevent the user from slipping out of the hand, and the inner side wall of the cotton swab sleeve 1 is provided with a rotating groove 12; the rotating groove 12 is located below the support handle 22; a built-in rotating block 13 is rotatably installed on the inner side wall of the rotating groove 12, and two limiting grooves 15 are provided on the inner side wall of the built-in rotating block 13; the two limiting grooves 15 are symmetrically provided.
[0025] A push handle 14 is slidably installed through the inner side wall of the built-in rotating block 13; the push handle 14 is fixedly connected to the lower end of the support handle 22; two limit blocks 16 are fixedly installed on the side end of the push handle 14; the push handle 14 is subjected to force to drive the limit blocks 16 to move, wherein the two limit blocks 16 are respectively slidably installed on the inner side walls of the limit slide groove 15, and the limit blocks 16 are subjected to force to slide in the limit slide groove 15, and when the limit blocks 16 contact the upper end of the limit slide groove 15, the limit slide groove 15 limits the limit blocks 16.
[0026] Working principle:
[0027] The first step is that when the nasopharyngeal hemostatic cotton swab with a sleeve is used, the elastic rubber ball 2 and the absorbent cotton layer 21 are compressed and stored in the cotton swab sleeve 1 during the process of passing through the nasal cavity. When the cotton swab sleeve 1 enters the nasopharynx, the rear edge of the push handle 14 is pushed, and the elastic rubber ball 2 and the absorbent cotton layer 21 are pushed out of the cotton swab sleeve 1. After being pushed out, the compressed elastic rubber ball 2 is expanded to open the absorbent cotton layer 21, so that the absorbent cotton layer 21 and the nasopharynx have a larger compression area, completely covering the nasopharyngeal biopsy wound, thereby achieving a better compression and hemostasis effect. The nasopharyngeal hemostatic cotton swab with a sleeve is designed to consist of an inner layer of elastic rubber ball 2 and an outer layer of absorbent cotton layer 21. During use, the push handle 14 pushes the support handle 22, and the support handle 22 pushes the elastic rubber ball 2 and the absorbent cotton layer 21 out of the cotton swab sleeve 1, and the compressed elastic rubber ball 2 and the absorbent cotton layer 21 are expanded to completely cover the nasopharyngeal biopsy wound, thereby achieving a better compression and hemostasis effect.
[0028] In the second step, when the nasopharyngeal hemostatic cotton swab with a cannula is used, the push handle 14 is pushed, and the push handle 14 moves to drive the support handle 22 to move. The support handle 22 is forced to push the elastic rubber ball 2 and the absorbent cotton layer 21, and the push handle 14 is forced to drive the limit block 16 to move. The limit block 16 is forced to slide in the limit slide groove 15. When the limit block 16 contacts the upper end of the limit slide groove 15, the limit slide groove 15 limits the limit block 16, so that the limit block 16 limits the push handle 14, and then the push handle 14 is rotated, and the push handle 14 is pushed. The built-in rotating block 13 is driven to rotate by the force, and the built-in rotating block 13 is forced to rotate in the rotating slide groove 12. The push handle 14 of the nasopharyngeal hemostatic cotton swab with a sleeve is limited, and the push handle 14 can drive the support handle 22 to rotate, so that during use, the limitable push handle 14 can prevent the elastic rubber ball 2 and the absorbent cotton layer 21 from pushing the cotton swab sleeve 1 too much, and the rotatable push handle 14 is conducive to fine-tuning the absorbent cotton layer 21, so as to better cover the nasopharyngeal biopsy wound surface, effectively improving the practicability of the device.
[0029] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
