Description

Negative pressure suction device

Technical Field

The utility model belongs to the field of medical equipment, especially, relate to a negative pressure suction device.

Background

In 1993, German Fleischmann finds that the wound surface is sealed and kept in a negative pressure state, so that the bacterial load of the wound surface can be reduced, and the healing time of the wound surface is shortened. In 1995, Negative Pressure Wound Therapy (NPWT) was formally approved by the U.S. food and drug administration for clinical treatment of soft tissue defects. Through long-term clinical application, the negative pressure wound treatment technology is proved to have good treatment effect on acute and chronic wounds.

The existing closed negative pressure suction device mostly needs to perform negative pressure suction treatment by means of a central negative pressure system of a ward, but wound outpatients have no treatment condition, so that the treatment effect of the outpatients is greatly influenced. In addition, some portable negative pressure suction devices are used in clinical treatment at present, but the negative pressure devices are generally large in size and not easy to carry about by a patient, and daily activities of the patient are seriously influenced; on the other hand, the price of the existing portable closed negative pressure device is more than 5000 yuan, and the cost is high, so that a plurality of outpatients abandon an effective treatment mode of negative pressure wound treatment.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem the utility model provides a negative pressure suction device.

The utility model discloses a realize through following technical scheme:

a negative pressure suction device comprises a negative pressure drainage bottle, wherein a drainage tube of the negative pressure drainage bottle is connected with a syringe shell, the drainage tube is hermetically connected with the tail part of the syringe shell, a catheter is arranged at the top part of the syringe shell, and a sponge is arranged at the tail end of the catheter; the sponge is provided with a blind hole, and the tail end of the catheter is inserted into the blind hole; the sponge is provided with a pad pasting which seals and fixes the sponge on the wound surface of the patient.

Preferably, the suction catheter is a disposable adult sputum suction catheter. The use has the advantages that: 1. the product is sterilized by ethylene oxide and is a disposable sterile product which is not required to be sterilized for use. Can be directly used for the wound surface of a patient without worrying about secondary infection; 2. the product material is easy to trim, and the corresponding side hole can be trimmed at any time according to the requirement of the wound surface, so that the smoothness of the drainage pipeline is ensured.

Preferably, the syringe housing has a capacity of 2 ml. The use reason is as follows: the 2ml empty needle can be directly connected with the suction catheter (the inner diameter of the disposable sputum aspirator F10 is 3.33mm and is matched with the diameter of the 2ml empty needle). The capacity of the negative pressure drainage bottle is 500 ml. The use reason is as follows: the negative pressure drainage bottle with relatively large volume is selected, so that sufficient negative pressure can be ensured to form effective negative pressure treatment in a vacuum environment; but does not select the drainage bottle with overlarge volume to influence the daily life of the patient.

Preferably, the joint of the catheter and the syringe shell and the joint of the syringe shell and the negative pressure drainage bottle are sealed and fixed through medical transparent films. The inner layer of the medical transparent film is a sterile surface, can play a role in safe and effective fixation, can form an effective closed environment, and can keep a negative pressure treatment state after negative pressure is applied.

Preferably, the port at one end of the catheter is inserted into the tail end of the blind hole of the adsorption sponge, and the tail end of the blind hole is positioned close to the bottom surface of the sponge, namely close to the position where the sponge is contacted with the wound of the patient. The applied adsorption sponge is very easy to cut, and can be randomly cut into required size and shape according to the wound surface of a patient.

Preferably, the sponge is fixed at the wound by adopting a skin-friendly medical transparent adhesive film.

Compared with the prior art, the utility model has the advantages of it is following:

the utility model provides a negative pressure suction device comprises devices such as negative pressure drainage bottle (500ml) more commonly used, cylinder shell (2ml), medical sponge, pipe (F10 disposable sputum suction catheter), medical transparent pad pasting, and is easy and simple to handle, and the price is far less than the like product (about 1/50). The utility model has the main advantages of simple material drawing and great convenience for the treatment of outpatient. Particularly for patients with unhealed wound for a long time, the treatment effect of the patients is improved due to the use of the closed negative pressure suction device while the frequent times of the patients for seeing a doctor are reduced. Clinical use proves that the price of the device is lower than that of similar products, and the device has good treatment effect, so that the treatment period of a patient is shortened, and the economic burden of the patient is also lightened.

Detailed Description

Example 1

As shown in fig. 1, the present embodiment provides a negative pressure suction device including: negative pressure drainage bottle 1, syringe shell 2, sponge 3, pipe 4, transparent pad pasting 5. Wherein, the common disposable negative pressure drainage bottle of preferred chooseing for use of negative pressure drainage bottle 1 is provided with the check valve on it, can produce the negative pressure through the extrusion body of the bottle, and the drainage tube that sets up through the bottleneck simultaneously links to each other with external equipment, and the capacity of preferred negative pressure drainage bottle is 500ml in this embodiment. The syringe housing 2 is the remaining syringe portion of a conventional syringe with the plunger rod removed, and a 2ml syringe is preferably used in this embodiment. The sponge 3 is preferably selected from common medical prepuce bags. The catheter 4 is preferably a disposable sputum aspirator. The transparent adhesive film 5 is an adhesive film with one side having viscosity, and preferably a medical transparent adhesive film with skin-friendly property.

The concrete connection relationship of the above-mentioned each part is: the sponge 3 is provided with a blind hole, one end of the conduit 4 is inserted into the blind hole, and the conduit 4 and the sponge 3 can be stably connected after one end of the conduit 4 is inserted due to certain elasticity of the sponge 3; meanwhile, the port at one end of the conduit 4 is inserted into the tail end of the blind hole, and the tail end of the blind hole is close to the inner surface of the sponge 3, so that negative pressure is formed on the inner surface of the sponge 3, namely the position contacted with the wound surface of a patient. The other end of the conduit 4 is connected with the top outlet end of the syringe shell 2, and in order to ensure the tightness, the position where the other end of the conduit 4 is connected with the top outlet end of the syringe shell 2 is sealed and fixed by a medical transparent film. The entry end of the tail of the syringe shell 2 is connected with the negative pressure drainage bottle 1, specifically, the entry end of the syringe shell 2 is connected with the drainage tube on the negative pressure drainage bottle 1, and the same position where the entry end is connected is sealed and fixed by a medical transparent film.
